1. Backyard Cat/Racoon Deterent

Current backyard deterent divices rely on either; triggered water sprinkler, ultrasonic sound and or flashing lights to deter cats and racoons from backyard gardens. These devices initially work, however, as animals get used to them, they figure out ways to "outsmart" the deterent. The team is to expected to design and build (budget of < $100) a non-harmful (to animals, humans and plants) multi-faceted deterent system.

2. Internet of Things (IoT) - Tomato Covers

On of the problems faced by gardeners in the spring is the risk of frost for tender tomato seedlings. A sensor based solution may be too late in covering the tomato seedling, as much of the heat may already be lost to surrounding air. Whereas a cover left on too long, may "cook" the seedling as heat builds up. Using an ESP8266 wifi module to get weather forecasts, temperature sensors, cloud computing and a servo motor, the selected team will build a device to cover tomatoes when the risk of frost is imminent, and uncover the tomatoes when the temperature warms up.

3. Lego Sorting Robot with DoBot Magician

Using a webcam, a PC and Matlab, your team is to design and build a lego sorting robot using the DoBot in the Mechatronics lab. The program (Matlab) should use machine vision to recognize the lego pieces and then sort them into bins. Specialized grippers, parts feeders, interfacing using an Arduino may be required and will be supplied. The ideal team would be made up of Solids Design, Manufacturing and Mechatronics students.

4. Self Balancing Lever

Working with a local industrial partner, the team will explore applictions of a self balancing lever (pantent pending). The intellectual property of this project will be protected by a non disclosure agreement (NDA) with the industrial partner.

Prof. Daolun Chen - EPH 340B

1.  Design of lightweight and corrosion-resistant magnesium body panels
The new fuel economy standards require automakers to bring the average fuel efficiency for all cars and trucks sold to 23.2 kilometres per litre (54.5 miles per US gallon) by 2025, nearly double the current average. According to a recent survey, lightweight structural materials will have the most impact in helping automakers meet fuel-economy targets. Design a new lightweight magnesium sheet metal panels for the next-generation auto production.
2. Design of a car engine cradle using lightweight magnesium alloys
Reducing weight in ground vehicles and aircraft is today considered as one of the most effective approaches to improve fuel economy and reduce anthropogenic environment-damaging emissions. The application of magnesium alloys, being the lightest structural metallic materials, has thus attracted considerable interest in the automotive and aerospace industries in recent years. Design a new car engine cradle using lightweight magnesium alloys to replace the heavier steel counterpart.
3.  Design of a rotating bending fatigue testing machine
A rotating bending fatigue testing machine will be designed to test smooth round specimens. Bending stress is applied to the specimen by means of dead weights. An indicator providing the number of completed cycles with automatic shut-off upon specimen failure and providing an indication of the operating speed (in rotations per minute or RPM) is needed.

4.  Design of a three-point bending fatigue test stage
A three-point bending fatigue test stage will be designed to fit into the existing Instron 8801 fatigue testing system, with a capacity of 50 kN and a factor of safety of 5.

Prof. Seth Dworkin - EPH 324

1. Design of an automatic sensor-controlled residential geothermal heating and cooling system

Geothermal heating and cooling (geoexchange) systems are becoming inexpensive and desirable in residential homes. They can provide an environmentally sustainable source of heating and cooling at competitive prices. Integrating a geoexchange system into an existing thermostat controlled dwelling is challenging.

The goal of this project is to design a geothermal ground loop heating and cooling system, suitable for an upscale residential dwelling (4000 – 6000 sq.ft). The system should be thermostat controlled in both the heating season and cooling season. It will have a ground loop through which fluid flows and takes on the ground temperature, a heat pump, a circulation pump, temperature and flow rate sensors, and a heat exchanger so that a forced air stream can be either heated or cooled. It should be hybridized with a conventional HVAC system for peak shaving. The control system should be able to intelligently decide which systems are running and at what time.

2. Residential Flood Prevention System
Residential floods can be caused by pipes freezing and bursting, or by leaks that spring from worn or faulty fittings and joints. Leak severity can be anywhere from a slow drip to a major flow. Leaks can cause flooding, especially when occupants are out of the house or away on vacation, and the leak goes undetected. Damage can range be hundreds of thousands of dollars, and may only be partially covered by insurance.

The goal of this project is to design a leak monitoring and flood prevention system, that can automatically detect leaks, distinguishing them from normal water use, and then alert the home owner and shut off the water to prevent flooding and major damage. The system should be relatively un-intrusive to install, simple to operate, and reliable.

Prof. Alan Fung - EPH340A

 1. Design, Prototyping, and Performance Testing of Transcritical CO2 based Heat Pump System (highest Priority and must be done in W2018)

This project entails the conceptual design, prototyping, and performance testing of a transcritical CO2 based heat pump integrated energy system suitable for mechanical engineering education and research. The project will eventually provide a set of equipment for our thermofluids/energy related laboratories to better reflect the current state and interest of alternative/sustainable/renewable energy systems by the society, industry, and students. This CO2 heat pump based integrated energy system will be capable for providing space heating, space cooling, and domestic water heating in current and future energy efficient/net-zero energy residential houses in North America. The overall system will be suitable and used for various levels of mechanical engineering courses to demonstrate fundamental thermodynamics concepts/cycles, heat transfer principles, applied integrated energy systems and the related control strategies, and environmental issues. It should be noted that this project is partially funded by Ryerson FEAS and Department of Mechanical and Industrial Engineering and ASHRAE. It is expected that the chosen team will start working with our local heat pump manufacturer, Ecologix, right away to develop/build the CO2 heat pump for performance testing with proper instrumentation. At least one of the team members, along with a member the previous team, will attend the ASHRAE 2018 Winter Conference to be held in Chicago at end of January 2018 to present the project.

2. Design and Prototyping of a Cloud-based Smart Dual Fuel Switching System (SDFSS) for Residential Hybrid HVAC System: (second highest priority)

For this project, we are seeking a control-focused capstone team to design, integrate, instrument, and develop a custom-made cloud-based Smart Dual Fuel Switching System (SDFSS). This project should be able to demonstrate and highlight the flexibility and effectiveness of these hybrid HVAC systems in terms of energy efficiency, and energy cost and greenhouse gas (GHG) emission reduction potentials to the homeowners, industry, and society. The expected cloud-based modeling and optimization platform should be suitable for the deployment of the SDFSS controller for a large number of residential houses simultaneously. If such a controller is widely deployed, it could potentially provide a cost effective and ubiquitous mechanism as a dispatchable load for utilities (both electric and natural gas) to better manage their infrastructure by maximizing the utilization of their assets through minimization of the mismatch between supply and demand under the smart grid infrastructure automatically and transparently without intervention by the home owners. Therefore, the proposed system will not only be beneficial to governments and utilities but also to home owners, by having a more flexible energy supply at a lower energy cost. It is expected that during the winter season the developed SDFSS will allow ASHP to operate at milder outdoor temperatures and/or during the off-peak electricity price hours while utilizing nature gas furnace at colder outdoor temperatures (when ASHP capacity and performance drop [2, 3]) and/or during the on-peak electricity price hours so that both energy cost and GHG emission can be minimized for residential space heating.

3. Design Refinement and Performance Testing of a Heat Transfer Enhanced Hybrid Air-based Roof-mounted Building Integrated Solar Photovoltaic/Thermal (BIPV/T) Collector: (lowest priority of the three projects and should be done after the first two are filled)

Building Integrated Photovoltaic/Thermal (BIPV/T) systems are arrays of photovoltaic panels integrated into the building structures such as facades and roofs that can produce electricity and recover useful thermal energy by circulating fluid behind the array of photovoltaic panels. This energy can be used for space heating, domestic water heating, and even air conditioning. For continuous and sufficient space heating in cold climate like Canada, BIPV/T systems must be coupled with air source heat pumps (ASHPs). Recent advances in two-stage (TS) variable capacity (VC) air source heat pump (ASHP) have demonstrated that such system can be successfully used with comparable overall performance of ground source heat pump (GSHP) in the harsh Toronto climatic condition (Kamel & Fung, 2014a; 2014b), cold in winter and hot in summer, without requiring any supplementary heat source even during the coldest period encountered at -22°C (Safa et al., 2015a; 2015b).  Thus, by providing space heating, domestic water heating, summertime cooling, and electricity production, the coupling of BIPV/T with two-stage VC-ASHPs will bring existing buildings closer to the goal of net-zero energy status in a cost-effective, environmentally-friendly manner, providing possibilities for long-term greenhouse gas (GHG) emission reduction, employment and green business opportunities.  Currently, there are a few challenges in making air based BIPV/T system a viable cost-effective net-zero energy building technology. Among them are 1) heat transfer enhancement to cool off PV panels while recovering thermal energy efficiently, and 2) efficient way of mounting PV panels to building facades (wall and roof) to ensure air- and water-tight system with ease of installation, service, and repair. Therefore, the overall objective of this project is to design and prototype structural insulated panel (SIP) supported BIPV/T collector(s) with enhanced heat transfer mechanism. The eventual prototype(s) will be used for both laboratory studies (both at Ryerson and Concordia University’s Solar Simulator and Climate Chamber facility) as well as for actual implementation at the full-scale (30ft x 25ft) BIPV/T test hut facility located at the TRCA Kortright Centre.  It is envisioned that the prototype(s) will include some kind of heat transfer fins attached at the back of the PV modules for allowing more efficient way to dissipate heat from PV modules into the moving cooling air between the PV modules and the SIP. Standardized PV module mounting system onto the SIP based building facades should be designed and prototyped, perhaps with the aid of 3-D printing technology. Other additional experimental study related equipment (such as variable drive fan/blower) and sensors (temperatures, solar radiation-pyranometers, and air flow rate) are to be selected and properly integrated into the prototype(s) for testing.

1. Design depth measurement system
This project is to design a depth measurement system for applications such as facial recognition, gesture recognition, mobile 3D scanner, 3D camera, etc. The depth measurement system includes the light source (e.g., scanning infrared light beam) and the detecting unit. It integrates both optical and mechanical parts, as well as simple circuits with a compact structure. Beside the design of the whole measurement system, one focus of the project lies in the design of the light beam scanning component.

The piezoelectric power harvesters are embedded in the road and can harvest and output power for a short time period to illuminate part of the road for vehicles to pass through. The system includes mechanical design, mechanics/vibration analysis, and design of simple control/circuits.


Prof. Wey Leong - EPH 306A

1. Designs of solar-assisted hybrid ground source heat pump systems
In this project, collected solar thermal energy during the summer is used to supplement the heating of a building in the heating season for a hybrid ground source heat pump system. Different innovative hybrid designs must be developed.

2. Design of a waste heat recovery system for electricity production
In this project, a heat recovery system will be designed to recover waste heat from hot flue gas for electricity production. The produced electricity will either be sold to the grid or be stored for use later.

3. Phase Change Material - constant water bath device
Working with a local industrial partner the team is to design a small device that will house organic phase change material (PCM) to control water temperature. The device, filled with the pcm, will be submerged into a container of boiled water (approx.8-14 oz) (100 degrees Celsius approx,). We will require the device to first reduce the temperature of the water to approx. 80 degrees C then slowly transfer the energy back into the water as the water temperature drops in an indoor environment. The initial goal is to maintain the temperature of the water at 80 degrees C for at least an hour. This will all happen in a temperature controlled 20-25 C room. Ideally the device could be electronically set to maintain a customized temperature depending on the size of the container (ex. set device at 10 oz, 80 C). All solutions and approaches are welcome. The intellectual property of this project will be protected by a non disclosure agreement (NDA) with the industrial partner.

Prof. David Naylor - EPH 

1. Design of a “Hands-on” Heat Conduction Lab for MEC710 Heat Transfer

The current heat conduction apparatus (used in MEC701 Lab 1) is not engaging for students. Typically, more than twenty students watch a teaching assistant set up and run the experiment.  The goal is to design an improved laboratory experience that gets students involved. The objective is to design an apparatus which is easy to use, i.e. with limited supervision from the teaching assistant. The time to achieve steady state conditions and an accurate measurement must be well within a standard two-hour lab period.  The design goal is to measure the thermal conductivity of an aluminum alloy 2024 bar with an accuracy of ±5%. The accuracy of the proposed design (and the time to achieve steady state conditions) will be predicted using simulation e.g. SolidWorks Simulation. A detailed experimental uncertainty analysis will be performed as part of the design process. Safety will also be a central concern, since this is a “hands-on” experiment for students.

The design team will select a commercially available power supply, heater(s), pump, constant temperature bath, instrumentation, etc. Once the design is finalized, a detailed budget will be prepared, in order to replicate the apparatus. Ultimately, the vision is to have five identical lab stations where small groups of students can measure the thermal conductivity of different metal samples and share their results.

2. Design of a Refrigeration Cycle Lab using an Off-the-Shelve A/C Unit:  

In our current lab, more than twenty students stand around one piece of equipment while the teaching assistant runs the experiment. This is not an engaging learning experience. The goal is to design a highly interactive lab, using a small off-the-shelf air conditioner (with the cover removed). This type of system could be replicated, so that each group of five students could have a hands-on experience with an actual A/C unit. They will be able to trace the piping system and identify the compressor, condenser, TXV (thermal expansion valve) and the evaporator on an actual commercial A/C system. At steady state operation, simple instrumentation (wattmeter, contact thermocouples and thermocouple reader, anemometer, etc.) will be used to:
-           Obtain the T-s diagram for the refrigeration cycle
-           Estimate the unit COP, cooling capacity, and mass flow rate of refrigerant
-           Estimate the evaporator and condenser pressure
-           Can other parameters be accurately measured? e.g.  isentropic efficiency of compression
This is not just an “on paper” design.  Funding to purchase a small A/C unit (5000 BTU) and all the required instrumentation will be provided by Dr. Naylor.
The project will involve testing and refining a very simple instrumentation system for an A/C unit. The design team will need to assess the assumptions and approximations used in the analysis of the data. The deliverables for the design team will include a draft of the lab instructions, suitable for use by engineering students in an instructional setting. These instructions will include the learning objectives, a description of the experiment, detailed procedures, and the A/C performance paramters to be calculated.
To be successful, the design team must deliver a turn-key lab experiment, suitable for use in MEC309. The design team will also prepare the detailed budget required to replicate the apparatus.
If the development of the apparatus proceeds quickly, the new hands-on lab could be tested with student volunteers. It would useful to get feedback on whether the hands-on lab is a better teaching tool than the current refrigeration apparatus. The goal is to demonstrate better student engagement and improved learning outcomes.

1. Design of an inline powder flow rate monitoring and adjustment system
The repeatability of abrasive jet machining operations is negatively affected by fluctuations in powder flow as it is mixed with the accelerating fluid.   In this project, the team will design a system to monitor and adjust the powder flow rate in real time, to ensure a steady powder mass flow rate.   Possible mechanisms for measuring flow rate to be investigated might include gravimetric, acoustic, or optical methods.  Whichever method is chosen will need to be coupled to a control system that allows rapid changes in flow rate to be made by instantaneous changes in powder reservoir orifice size.

2. Design of a whirling arm abrasive jet micro-machining apparatus operating in a vaccum
Abrasive jet micromachining uses a jet of  compressed fluid to accelerate micro-abrasive particles to high speeds.  The jet impinges a target which has been covered with an erosion resistant masked pattern in order to create features such as microchannels, etc.   It has been found that more accurate and smaller features can be made if the size of the abrasive particles is decreased.  However, at below ~<10 um, aerodynamic effects hinder the ability of the particles to strike the surface as the particles tend to follow fluid streamlines.   This difficulty could be overcome if the machining was performed in a vacuum.  To this end, the team will design a whirling arm apparatus to launch the particles, and a vacuum chamber in which to perform the machining.  Possible avenues for feeding the particles into the whirling arm will also be explored.

Prof. Fil Salustri - EPH 306B 1.  Re-conceptualizing the clothes dryer
The clothes dryer is the second most energy-consumptive appliance in a typical North American household, yet little attention has been paid to it. The task is to re-conceptualize the clothes dryer with the particular goal of lowering energy consumption. This project involves examining every assumption made about existent clothes dryers, and looking at innovative - though not necessarily “high-tech” - ways to dry clothes. Some key aspects include: how to heat air efficiently; how to distribute that air evenly within the dryer; how to prevent waste heat; and how to control the heating process for improved efficiency. The project may focus on one or more of these features.

1. Design and simulation of microfluidic chemical mixing channels

Microfluidic lab-on-a-chip systems have become ubiquitous in biomedical research. For example, microfluidic devices have been used for single cell studies, DNA sequencing, and drug testing. Due to the small-scale of microfluidic systems, microfluidics is well-suited for manipulation of cell-scale biological agents and particles, and reduces the amount of reagents required during experiments. 

However, despite the promise of microfluidics to miniaturize and transform biochemical assays, microfluidic devices are still hampered by slow molecular diffusion process at small scales. Since fluid flow in microfluidic systems is completely laminar, diffusion happens only passively. Many diffusion-limited reactions are very slow as a consequence of this weakness of microfluidic devices. It is therefore desirable to develop microfluidic mixing channels that increase the diffusion area between different chemical effluents, without dramatically increasing the overall footprint of the microfluidic devices.

In this project, the students will use COMSOL Multiphysics, to design various microfluidic channel geometries, and simulate fluid flow and diffusion dynamics in the channels, to analyze the channel's fluid mixing efficiency. Students will review the scientific literature to understand what designs may improve mixing efficiency, develop their own ideas on new designs, and implement those designs in COMSOL Multiphysics.

2. Design and simulation of microfluidic geometries that enable the separation of particles by size and density

Microfluidic lab-on-a-chip systems have become ubiquitous in biomedical research. For example, microfluidic devices have been used for single cell studies, DNA sequencing, and drug testing. Due to the small-scale of microfluidic systems, microfluidics is well-suited for manipulation of cell-scale biological agents and particles and reduces the amount of reagents required for experiments.

One of the most important microfluidic biomedical applications is microscale flow cytometry--the separation of two or more types of particles based on their physical and/or biological properties. The capability to efficiently separate microparticles may find utility in cell sorting, enrichment, and isolation. While microfluidic flow cytometry by electromagnetic means has been demonstrated in the past, these approaches require the microparticles to be "tagged" by objects that are either magnetic or produce an electrical dipole under an applied electric field. To date, there has not been a widely accepted way to perform microfluidic flow cytometry without applying electromagnetic tags.

In this project, students will use COMSOL Multiphysics to design various microfluidic channels that enable the efficient separation of two types of particles by particle size and density, without tagging the particles. Students will review the relevant scientific literature to understand the state-of-the-art techniques being employed for microfluidic flow cytometry, and devise new and novel designs to exploit physical phenomena (e.g. inertia) to separate the particles in microfluidic systems.

1. Design of a DC- or AC- powered light-duty electrical declogger  
In many household or industrial settings, u-bend or other types of bends are used for connections or their purposes in their piping systems. As a result, debris and foreign objects tend to rest and clog the piping systems.  In this capstone project, a light-duty declogger will be designed to clean up a clogging in 1.25, 1.5 and 2” bends.  Below are the requirements
-          The brushing-head will penetrate at least 3 feet into a pipe of various curvatures.

-          The shaft carrying the brush head need to be flexible and rotate. 

-          The brushing head need to have the object-conveying function to transport the clogging debris out in a continuous manner. 

-          For a compact design and efficiency, a quiet multi-stage PGT is needed to reduce the speed from the motor shaft to the brushing head. 

-          A prototype is desired but not required.  

-          Other requirements: low noise, durable, affordable. 

2. Design of a wheel-less vehicle for climbing and other treacherous tasks   
Traditional machines empowered by various mechanisms to achieve some complex functions or motions with reference to its base, frame or ground either fixed in space or whose motion is irrelevant. Now in this project, motion of the base is the key.  The delivery of base motion is done through the coordinated mechanisms, gravity and contact.  The objective of the project is to design two or more planar or spatial mechanisms driven by one or multiple “engines” or “motors” to move in a coordinated manner to deliver the desired motion of climbing a hill with bumps.        

3. Design of a motor-driven high speed flexible mechanism for dynamic stability studies 
A testing machine driven by an AC/motor and speed controller is to be designed and made to validate experimentally the dynamic instability theory of a high-speed flexible mechanism (crank rocker) with a speed increaser under idle and load conditions.   .

In both small and large companies, new engineering projects are often farmed out to engineering consulting companies.  To hire the right consultants, companies will put out a Request for Proposals (RFP).  An RFP is a way for consulting companies to bid on engineering projects.  In a way, its lays out how an engineering project should proceed, and a method to explain to your potential client why you have the expertise to carry out this project.

For MEC825 - the design projects will be given to groups based on the merit of their RFP.  Your proposal should include the following information:

Page 1 - Executive Summary - a brief description of your project
Page 2 - Information about your team, qualifications and contact information
Page 3 & 4 - Detailed description of the project
Page 5 - Quality, testing and benchmarking
Page 6 - Project stages and milestones
Page 7 - Deliverables at the end of the project
