Our idea is a dock for a bicycle which will allow a person to exercise in a fixed location and monitor their physical activity while charging a battery, or devices. This idea is novel because while designs that accomplish one of the two tasks exist, they are very expensive, and require an invasive procedure on the bike. There are independent objectives for this project that we will focus our attention towards. First, we can increase the efficiency of converting torque to electrical power. However, we will not sacrifice any other objectives, so our generator may not produce the advertised 100 to 300 watts out there in the open market. Second, we will charge our own exercise monitor as well as phones, tablets, and laptops. Laptop batteries can store about 45 watt-hours of energy, and our machine's goal is to charge it to full in one hour. Third, our exercise monitor will measure energy generated and distance travelled. Fourth, our project is meant to be cheap and easy to set-up. We want to avoid requiring users to take apart their bike like their rear wheel. The hardware aspects of this project will consist of two main components. The first subsystem is the power aspect of the project which will include generators, a battery, and conversion between ac and dc power. The second subsystem will be the exercise aspect of the bike. This will involve counting the rotations of the wheel and using it to calculate the speed, distance and approximate calories burned. We will most likely use an encoder, a few discrete integrated circuits and a processor in this step. Minor aspects will be software implementation to calculate exercise stats, and system identification of mechanical and electrical components. https://courses.engr.illinois.edu/ece445/pace/view-topic.asp?id=26987 (our idea post) |
