Bicycle Control Body Layout for Separate Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle controls with electrically operated gearshifts complicate access to the electronic board and battery, necessitating simultaneous removal during maintenance or replacement, which is inconvenient and time-consuming.
Innovation Solution
An integrated control system with two distinct openings in the control body allows separate access to the electronic board and battery, facilitating independent installation and maintenance by enabling independent placement and connection of these components without requiring simultaneous removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery and electronic board are housed in the same cavity with a single opening, then the control body structure is simplified, but access to components for maintenance and replacement becomes complicated and time-consuming
Solution Approach 1:
The single opening in the control body is segmented into two separate openings: a first opening for accessing the electronic board and a second opening for accessing the battery. This segmentation allows independent access to each component, enabling maintenance personnel to replace the battery without removing the electronic board and vice versa, thereby significantly improving ease of repair while maintaining structural simplicity
2Device complexity
If the battery and electronic board are accessed through the same opening, then the number of openings is minimized, but maintenance time and downtime increase due to simultaneous removal requirement
Solution Approach 1:
The access opening is segmented into two distinct openings positioned at different locations on the control body. The first opening provides access to the electronic board while the second opening provides access to the battery. This segmentation eliminates the need to remove both components simultaneously, reducing maintenance time and operational downtime while adding minimal structural complexity
Solution Approach 2:
The battery is positioned and secured in the cavity before the electronic board during assembly. This preliminary placement allows the battery to be pre-installed and connected, so that during maintenance, only the electronic board needs to be accessed through the first opening while the battery remains accessible through the second opening, thereby reducing the time required for maintenance operations
