Improving Tricycle Biomechanics: Concept

Tricycle Biomechanics TeamMarch 22, 2007Xin He, Katherine Wong, Mario Bollini, Elizabeth Au, Lindsay Todman

Community Partnership

Abdullah: tricycles versus wheelchairs Medical, environmental, stigmatic

reasons Rory: synchronous versus

asynchronous crank Power efficiency, mobility

General difficulty in communication

Concept: Modify Current System

Provides tangible results for community partners by the end of the term.

Will seek to optimize: Gear ratio Crank configuration

(synchronous vs. asynchronous)

Crank position Steering system

Modules

Steering Gears

Ratio, derailers, speed, arms

Crank Symmetric and

Asymmetric Adjustability Position

Next Step:Testing power output

Find the maximum power output for different people using the hand crank

This power output should be measured for a reasonable period of time to ensure it is sustainable

Vary the position of the crank and see how the power output changes
