P16214: Bicycle Power Meter

Project Summary Project Information

Problem Statement:

A bicycle power meter is a device used by professional and amateur cyclists in order to show the cyclist their power output on the bicycle. The RIT Cycling Team approached this MSD team to provide a power meter for their Imagine RIT bicycle blender exhibit. Their desire is to have this device take the input force from the cyclist and display their power output and calories burned. The current devices on the market which provide these features are not quite instantaneous. There is a lag associated with the time between the rider exerting force on the bike and when the rider receives feedback from the system.

The goal of this project is to develop a functioning power meter for the bicycle blender exhibit. In order to achieve this task the MSD team aims to improve upon the communication speed between the power meter sensors and the display in existing devices. This will assist in achieving a more instantaneous system and closer to real-time display.

The preliminary rough outline for the scope of this project can be found at the Project Readiness Package.

MSD I

As seen above our MSD team came up with a problem statement that we plan to solve for the RIT cycling team by the end of the Senior Design Project. After the problem statement was created more thought was put into how we would define this problem further and some initial steps were taken on how we plan to over come the problem that we are faced with. More information for the initial phases of this project, where items such as the potential use cases and the key customer requirements were defined, can be found at the Problem Definition page.

After having a list of customer requirements, engineering requirements, and some constraints and preliminary risks that we may face during this project we were ready to brainstorm some preliminary concepts for our system design. The system design phase containing our MSD team concept generation with selection criteria designed to meet all of our customer requirements can be found at the Systems Design page.

Once the Systems Design for the bicycle power meter was solidified our MSD then turned our attention to come up with clearer subsystems designs. The overall bicycle power meter systems was broken into the following subsystems: crankarm/crankset, strain gauges, microcontroller (containing bluetooth capabilities), accelerometer, battery, and the smartphone app. Our MSD team deliberated on the best designs for each subsystem and were able to create the subsystems design. The selection of each subsystem design can be found at the Subsystem Design page.

After the subsystems for the bicycle power meter were clearly laid out the MSD team then decided to develop our preliminary detailed design for our device. The Preliminary Detailed Design phase was used to start making final design decisions by first starting with the higher risk items and putting more focus into solving these issues and trying to mitigate these issues prior to the final detailed design. The finalized design decisions for this MSD team can be found at the Preliminary Detailed Design page. This page also contains some of the testing and analysis that was performed to come to the conclusion of the finalized design decisions.

The Preliminary Detailed Design answered most of our high risk items and left us with a design that was roughly 90% complete. This helped to lead our MSD team into the next design phase which is the Detailed Design phase. The purpose of this phase is to completely finalize the design for our Bicycle Power Meter. This phase focuses on the low risk items that still need to be solved. Continuing on from last phase, more testing was completed in this phase to verify that our MSD team did in fact make the correct design choices. The finalized design decisions and the results of the continued testing can be found at the Detailed Design page. By the end of this phase our MSD team was in a very good position to start MSD II which is the building and testing part of this Senior Design Project.
