Adjustable Bicycle Operating Device Connector
Solution Overview
Problem
Conventional bicycle brake and shift operating devices are often difficult to operate when integrated, as the fixed relative positions can hinder accessibility and usability, especially when the shapes of the operating members do not align optimally with the handlebar.
Innovation Solution
A bicycle operating unit connector that includes a first operating unit with a clamp portion, a second operating unit with a housing, and a connecting member with adjustable attachments allowing for independent linear and angular adjustments of the second operating unit relative to the first operating unit and the handlebar, enabling flexible positioning and improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the shift operating device is attached to the handlebar inside the bracket of the brake lever, then the device integration is improved, but the ease of operation deteriorates
Solution Approach 1:
The invention divides the operating device into separate functional modules: a brake lever assembly and a shift operating device assembly, connected through a connecting member. This segmentation allows each component to be positioned independently for optimal operation while maintaining overall integration through the connecting member that attaches to the handlebar bracket.
2Device complexity
If the brake lever and shift operating device are fixed relative to each other, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The connecting member incorporates adjustable connection mechanisms including slots and adjustment holes that enable dynamic repositioning. The shift operating device can be adjusted along the longitudinal axis and angularly oriented to accommodate different handlebar shapes and user preferences, transforming a static fixed-structure into an adaptable dynamic system.
3Manufacturing precision
If the shift operating device is positioned in a fixed location, then the manufacturing precision requirements are simplified, but the ease of operation deteriorates
Solution Approach 1:
The connecting member features adjustable parameters including longitudinal position (via slots and adjustment holes) and angular orientation. This allows the shift operating device to be positioned at multiple discrete locations and angles, enabling optimization of operational accessibility without requiring high-precision fixed positioning during manufacturing.

AI summary
A bicycle operating device is provided with a first operating unit, a second operating unit and a connecting member. The first operating unit includes a clamp portion for attaching the bicycle operating device to a bicycle and a first operating member. The second operating unit includes a second operating member. The connecting member includes first and second attachment portions. The first attachment portion is detachably attached to the first operating unit by a first adjustable connection. The second attachment portion is detachably attached to the second operating unit by a second adjustable connection. The first adjustable connection changes a relative position of the connecting member with respect to the clamp portion in a first direction. The second adjustable connection changes a relative position of the connecting member with respect to the second operating unit in a second direction that is different from the first direction.
