Bicycle Fitting System Using Motion Capture for Rider Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle fitting systems face challenges in determining a suitable riding posture for riders due to variations in rider body characteristics, bicycle types, and riding types, making it difficult to achieve optimal comfort and performance.
Innovation Solution
A bicycle fitting system that includes a controller programmed to assess the rider's flexibility level using a motion capturing apparatus, measuring rider body parameters, and adjusting bicycle components such as the seat and handlebar based on these parameters and category information like bicycle and riding types to determine appropriate positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bicycle fitting systems measure rider body sizes and adjust bicycle components based on body sizes, then basic fitting can be achieved, but suitable riding posture cannot be determined due to variations in rider body characteristics, bicycle types, and riding types
Solution Approach 1:
The system transitions from measuring only static body sizes to measuring dynamic body parameters including flexibility levels through motion capturing apparatus. This parameter expansion allows the system to account for variations in rider body characteristics, bicycle types, and riding types, thereby improving adaptability while maintaining measurement precision through comprehensive data collection
Solution Approach 2:
The fitting assessment is segmented into multiple independent measurements: body size parameters, flexibility levels, and dynamic movement parameters. Each parameter is measured and evaluated separately, then integrated to provide a comprehensive fitting assessment that addresses individual rider characteristics accurately
2Ease of operation
If bicycle components are adjusted based on rider body sizes alone, then fitting process is simple, but rider comfort and performance cannot be optimized
Solution Approach 1:
The system enables automatic measurement of multiple parameters including flexibility levels and dynamic body parameters through motion capturing apparatus. This self-service capability reduces manual intervention while comprehensively assessing rider characteristics, thereby maintaining ease of operation while significantly improving the reliability and effectiveness of fitting results
Solution Approach 2:
The system incorporates continuous feedback loops where measured parameters (body sizes, flexibility levels, dynamic parameters) are used to automatically adjust bicycle component positions. This feedback mechanism ensures that adjustments are based on comprehensive rider characteristics, improving fitting effectiveness while maintaining operational simplicity through automation
