The Titan Lift: Automatic Bench Press Assist, 2013/2014 - 4th year project, UBC
- Researched, designed, built a pneumatic bench press system to assist the lifter if needed
- Presented and wrote reports on the process to the final product
The Titan Lift will provide a spot and additional assistance to the user once activated by the user via a stomp pad. Additionally, the Titan Lift will meter the level of assistance it provides to only effectively remove sufficient weight from the total weight, enabling the user to complete their repetitions safely.
The Titan Lift utilizes an electrical system, pneumatic system and a microcontroller. The pneumatic systems primary function is to engage the pneumatic pistons to support and raise the weight the user is bench pressing. The microcontroller receives electrical input signals from the stomp pad and pressure sensor and converts the electrical input signals into engineering units necessary to model the current state and operation of the pneumatic system. After the status of the pneumatic system is known, the microcontroller sends electrical output signals to the electro-pneumatic transducer and solenoid to make the necessary changes to the pneumatic system as dictated by the microcontrollers code. The coding of the microcontroller is designed as a feedback loop, constantly checking for and minimizing the feedback error.
Cooling Motorcycle Jacket, 2012/2013 - 3rd year project, UBC
- Researched, designed, built a jacket to keep the user cool while riding in the hot summer sun
- Presented and wrote reports throughout the entire process
Our group conducted research, developed mathematical models and used decision matrices to identify a suitable design for a motorcycle jacket that protects the rider while keeping the rider’s core temperature at a comfortable level. The chosen design utilizes a phase change material inside the motorcycle jacket in conjunction with a refrigeration cycle on the bike, to keep the riders temperature at a comfortable level, without compromising safety. The motorcycle jacket was manufactured with leather and used R-134A as the refrigerant and MPCM 24-D as the phase change material.
Volumetric Water Flow Meter, 2010/2011 - 2nd year project, UBC
- Designed and built a flow meter that could easily attach to a shower head to keep the consumer aware of their water usage
- Presented and wrote multiple reports during the course
The basic principle behind our idea was, once purchased a person would unscrew their shower head and screw our flow meter onto the pipe and the shower head back onto the flow meter. An LED screen protruding from the side of the flow meter will display the amount of water used during an shower and this can be turned on and off by a waterproofed mechanical switch. There are three main parts to our design; the measurement system – which will be in direct contact with the water and pipes, the hardware and LED screen and lastly the housing unit that will in case everything.
