Bicycle Brake Lever Segmentation for Flexible Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle operating devices lack flexibility in design due to the integration of electrical switches and wireless communication units, which limits their integration with various bicycle components and user convenience.
Innovation Solution
A bicycle operating device comprising a base member and a brake operating member with an electrical switch and wireless communication unit, where the electrical switch is positioned near the user's hand and the wireless communication unit is separately located, allowing for flexible design and enhanced communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electrical switch and wireless communication unit are integrated into a single electrical unit, then the device structure is simplified, but the design flexibility of the brake operating member and base member is reduced
Solution Approach 1:
The electrical unit is divided into two separate units: an electrical switch unit and a wireless communication unit. This segmentation allows each unit to be independently sized and positioned, enabling flexible design of the brake operating member and base member while maintaining overall structural simplicity
Solution Approach 2:
The patent utilizes spatial distribution by placing the electrical switch and wireless communication unit at different positions (one on the brake operating member, the other on the base member). This dimensional separation resolves the conflict between integration simplicity and design flexibility
2Volume of moving object
If the wireless communication unit is positioned close to the electrical switch for compact design, then the device size is reduced, but the communication performance and user access are degraded
Solution Approach 1:
By separating the wireless communication unit from the electrical switch into different components (brake operating member and base member), each unit can be optimally positioned for its function. The electrical switch remains accessible to the user's hand while the wireless communication unit is positioned for optimal signal transmission
Solution Approach 2:
Each unit is positioned at its optimal location: the electrical switch is placed where the user's hand naturally rests for easy operation, while the wireless communication unit is positioned separately to ensure optimal communication performance without being constrained by compactness requirements

AI summary
A bicycle operating device comprises a base member, a brake operating member, an electrical switch, and a wireless communication unit. The brake operating member is movably coupled to the base member. The electrical switch is to provide an electric signal. The electrical switch is disposed at one of the base member and the brake operating member. The wireless communication unit is connected to the electrical switch to transmit a wireless signal based on the electric signal. The wireless communication unit is disposed at the other of the base member and the brake operating member.
