Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-powered vehicle operating devices have complex structures and limited flexibility in controlling multiple operated units using multiple operating members.
Innovation Solution
The operating device incorporates a base structure, a circuit board with electric switches, and multiple movably coupled operating members. The electric switches are activated by the movement of the operating members, and their arrangement on the circuit board simplifies the structure while enhancing control flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electric switches are provided separately from the circuit board, then the operating device has a more robust structure, but the structure becomes complex and flexibility in controlling multiple operated units is limited
Solution Approach 1:
The patent integrates multiple electric switches directly onto a single circuit board, merging what would traditionally be separate components into one unified structure. This consolidation reduces the overall number of parts, simplifies assembly, and enables more flexible control configurations for multiple operated units while maintaining structural robustness through the circuit board's integrated design
2Adaptability or versatility
If multiple operating members are added to control multiple operated units, then control flexibility is improved, but the device structure becomes more complex
Solution Approach 1:
The circuit board is designed as a universal platform that can accommodate multiple electric switches and control multiple operated units through a single integrated structure. This multi-functional design allows the same circuit board to handle various control functions without requiring separate structural assemblies for each control element, thereby improving control flexibility while preventing structural complexity from increasing proportionally
