1. Automated delivery package lock box

A number of devices have come onto the market that provide a porch lock box to prevent delivery theft. However, these tend to be quite large and take a lot of space on the porch. Your team is tasked to design a package recepticle that is small and unobtrusive on the porch, but using sensors and servo motors (driven by a battery powered arduino), expands to secure the package once the delivery person has placed the box on the device. Due to the pandemic, only the design is expected at the end of the semester. (no prototype)


2. A Smart Anti-squirrel Bird Feeder

Many bird feeders use passive mechanical devices (springs, baffles, etc) to prevent squirrels from feeding on seed at a bird feeders. In this project, you are asked to design an acitve anit-squirrel bird feeder using an Arduino, sensors and servos. Due to the pandemic, only the design is expected at the end of the semester. (no prototype)

3. Arduino interfaced Dynamometer

A Prony break is a simple device used to measure the torque and power output of a motor or engine. In this project, you will design a small Prony brake to gather data to measure the torque and power curves for small hobby sized electric motors and gear motors. The data that you will need to gather: voltage, current, torque (force & distance), power (mechanical = torque x rpm and electical = voltage x current) and store this data on an SD card in an Excel format. Your Prony brake should be able to adapt to different motor & gear motor sizes with different output shaft sizes. More explanation is available on my video: link

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.

Project 1 Scanning LIDAR based interactive projection screen

Student will develop an interactive projection screen based on a general projection screen (cloth, flat wall, etc.), a projector, a computer and scanning LIDAR (light detection and ranging). The 1D scanning LIDAR is mounted at the corner of the screen. Once presenter’s figure touches or is (1~2 mm) close to the screen, the LIDAR detects the finger’s position and send it to computer. The computer is connected to the projector and superimposes an image (e.g., buttons) to the PPT slide, which is projected to the screen. Once the computer receives the signal from the LIDAR on the finger’s position on the screen, the following action is taken by the computer, e.g., 1) if the finger is on one of buttons (e.g., “page-down” or “page-up” or “Enter” or keyboard), the computer will control the PPT software to page down/up/enter or respond to key board input; 2) If the finger is not on the button position, the computer can follow the trajectory of the finger tip to draw a line for highlighting. That line is superimposed on the PPT slide in a real time mode. Similar interactive projection screens are available in the market but very expensive. This project is to develop a low cost interactive projection screen. The students are to: 1) Design the whole system; 2) Purchase parts including the single-point LIDAR; 3) Developing the micromirro based 2D scanning LIDAR by integrating a 1D scanning micromirror with the single –point LIDAR 4)Developing the software; 5) Developing the hardware for mounting; 6) Testing.

Project 2 Scaning micromirror and retroreflective material based interactive projection screen

Student will develop an interactive projection screen based on a general projection screen (cloth, flat wall, etc.), a projector, a computer and a laser scanner using micromirror. The laser scanner is made of a scanning micromirror, an infrared laser and a photodiode (photo detector). Two such scanners are mounted at two lower corners of the display screen. A rim/wall made of retroreflective material is mounted on the top of the display screen. Once presenter’s figure touches or is (1~2 mm) close to the screen, the scanner can detect the finger’s position on the screen and send it to computer. The computer is connected to the projector and superimposes an image (e.g., buttons) to the PPT slide, which is projected to the display screen. Once the computer receives the signal from the scanner about the finger’s position on the screen, the following action is taken by the computer, e.g., 1) if the finger is on one of buttons (e.g., “page-down” or “page-up” or “Enter” or keyboard), the computer will control the PPT software to page down/up/enter or respond to key board input; 2) If the finger is not on the button position, the computer can follow the trajectory of the finger tip to draw a line for highlighting. That line is superimposed on the PPT slide in a real time mode. This project is to develop a low cost interactive projection screen.

Active Electrical Heating Stick for Keeping Coffee Hot

Hot coffee can become cold quite quickly. This will lead to less favorable enjoyment for some coffee drinkers. In order to keep the coffee hot for a longer period of time, a smart coffee heating stick is to be designed. It should be small and portable. It will sense the temperature of the coffee and automatically maintain an appropriate/desirable temperature setpoint of the coffee using an active electrical heating in the stick. A controller will analyze the rate change of coffee temperature and adjust an appropriate power to maintain the coffee at an appropriate/desired temperature of the coffee. Once the battery is low, it will turn on a light indicator to signal the coffee drinker to quickly drink the coffee before it becomes cold and also to indicate that the stick should be recharged before its next use.

(note: Dr. Leong is only taking on 1 additional group)

1) Design of a portable generator for back-country camping using water power

The aim is to design a device that can harvest the energy from moving water in order to provide power for back-country camping trips. The device could use wave power or employ a water turbine to generate electricity which would then be stored in a battery. The device must provide a footprint that is 20 cm square or less, and be able to at least provide a 50% charge on a typical cell phone battery based on the energy harvested overnight (~ 8hrs). It should weigh no more than 1 kg. It is assumed that lake conditions will be those that are typical for a lake in Algonquin Park during the summer months.

2) Design of a portable generator for back-country camping using wind power

Project 1. Design of a microfluidic platform for mRNA-encapsulating lipid nanoparticles

Microfluidic systems have become ubiquitous in biomedical research. In the current COVID-19 pandemic, some of this research has emerged to become critical elements in the development of the most effective vaccines, namely the mRNA vaccines from Pfizer and Moderna. Due to the degradation of mRNA in the body, scientists encapsulate the mRNA in lipid-coated nanoparticles to formulate the vaccine--this is done using approaches developed through microfluidics. Despite the success of microfluidics for lipid nanoparticle generation, this process is still hampered by slow molecular diffusion at small scales--hence, large-scale manufacturing of the mRNA vaccines have required alternative, higher throughput approaches. Since fluid flow in microfluidic systems is laminar, diffusion happens only passively. Many diffusion-limited reactions associated with nanoparticle formation are slower as a consequence of this weakness of microfluidic devices. It is therefore desirable to develop enhanced 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, and utility in generating lipid nanoparticles. Students will review the scientific literature to understand how the current mRNA-encapsulating nanoparticles were developed, what designs may improve mixing efficiency. Then, students will develop their own ideas on new designs, and implement those designs in COMSOL Multiphysics.

Project 2. Stress and displacement analyses of modern enduro hardtail mountain bike frames

Mountain bike geometry has evolved significantly over the past decade, as the sport of mountain biking has generally become more technical. Aside from cross country racing bikes, most mountain biking disciplines have become more decent-oriented, thereby necessitating modern mountain bike designs that have "longer, lower, and slacker" geometries. This evolution is also true for hardtail mountain bikes (bikes that have a suspended front end, and a rigid back end), culminating in the recent emergence of "enduro" hardtails. The newness of the sub-category of enduro hardtails means that the frame designs likely have room for improvement. In this capstone project, students will learn to use finite element analysis (via COMSOL Multiphysics software), in combination with computer-aided design (via SolidWorks software) to study a roster of modern enduro hardtail mountain bike frames. Students will perform stress and displacement analysis of each hardtail frame, and identify strengths and weaknesses of each design. Finally, students will use the knowledge gathered to design a new enduro hardtail frame that simultaneously achieves the goals of maximizing compliance over technical terrain, minimizing energy loss during pedaling, balanced handling, and good durability.

Topic 1 Design of an electric powered food processor

To prepare fine Italian/Greek/Chinese cuisine, vegetables and meat need to be chopped into desired sizes and shapes. It is difficult to accomplish the tasks with the traditional rotating type of food processor. In this capstone project, a light-duty food processor with reciprocating blades will be designed to do the jobs efficiently for household and industrial uses. The most important design is the 3D mechanisms with single input and multiple coordinated outputs. Below are the requirements - Adjustable stroke - Adjustable angular feed - Twin blades - Durable and affordable - Quiet - For a compact design and efficiency, a multi-stage PGT is needed to reduce the speed from the motor shaft to desired linear/angular speeds at the output shafts/joints. - A prototype is desired but not required.
