Solution Overview
Problem
Existing bicycle operating devices have complex structures due to the integration of electrical switches within the brake and additional operating levers, making wireless operation of electrical bicycle components cumbersome and difficult to simplify.
Innovation Solution
A bicycle operating device with a base member, brake operating lever, additional operating lever, electrical switch, and wireless communication unit, where the electrical switch is disposed at the base member, simplifying the structure of the brake and additional operating levers and enabling wireless operation of electrical bicycle components with a mechanical control cable or hydraulic fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the electrical switch is disposed within the brake operating lever or additional operating lever, then the wireless operation of electrical bicycle components is enabled, but the structure becomes complex and difficult to simplify
Solution Approach 1:
The patent separates the electrical switch from the operating levers and places it on the base member. This segmentation allows the brake operating lever and additional operating lever to maintain simple mechanical structures while the electrical switch independently provides wireless communication functionality, resolving the contradiction between automation and structural complexity
Solution Approach 2:
The base member acts as an intermediary carrier for the electrical switch. By placing the electrical switch on the base member rather than integrating it into the moving levers, the patent enables wireless communication functionality without complicating the lever structures, as the base member serves as a stable platform for housing electronic components
2Device complexity
If the electrical switch is disposed at the base member, then the structure of brake operating lever and additional operating lever is simplified, but the actuation mechanism must be designed to press the switch from the base member
Solution Approach 1:
Instead of having the operating levers directly activate the electrical switch through integration, the patent inverts the approach by having the levers activate a mechanical control cable or hydraulic unit that indirectly actuates the electrical switch on the base member. This inversion simplifies the lever structures while maintaining ease of operation through the indirect actuation mechanism
3Adaptability or versatility
If the additional operating lever is pivotally coupled in multiple directions to the base member, then the movement freedom is increased for electrical component operation, but the structural complexity increases
Solution Approach 1:
The additional operating lever is designed with multi-directional pivotal coupling capabilities, allowing it to function as a universal control element for different electrical bicycle components. By enabling the lever to pivot in multiple directions (first direction for one function, second direction for another function), the patent achieves versatility without requiring separate control mechanisms for each function, thus balancing adaptability with structural efficiency

AI summary
A bicycle operating device comprises a base member, a brake operating lever, an additional operating lever, an electrical switch, and a wireless communication unit. The brake operating lever is pivotally coupled to the base member in a first direction. The additional operating lever is pivotally coupled to one of the base member and the brake operating lever in a second direction and in a third direction different from the first direction and the second direction. The electrical switch is to provide an electric signal in response to a movement of the additional operating lever in the third direction. The electrical switch is disposed at the base member. The wireless communication unit is connected to the electrical switch to transmit a wireless signal based on the electric signal.
