Bicycle Operating Device with Hybrid Mechanical and Electrical Control
Solution Overview
Problem
Current bicycle operating devices lack an efficient mechanism to simultaneously operate multiple bicycle components, such as transmission and seatpost adjustments, using a single intuitive interface, which complicates user operation and control.
Innovation Solution
A bicycle operating device comprising a base member, an operating member, and an operating structure with a take-up member that moves operation cables to control first and second bicycle components, along with an electrical switch and controller for user input operation, allowing independent control of both components via a single interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate operating devices are used for different bicycle components, then each component can be controlled independently, but the device complexity and number of controls increase
Solution Approach 1:
The operating device integrates multiple functions into a single control unit. The operating member can control both the first bicycle component (via cable operation) and the second bicycle component (via electrical switch), allowing one device to perform multiple control functions that previously required separate devices.
Solution Approach 2:
The patent combines the mechanical cable operation system and the electrical control system into a single integrated operating device. The operating member serves as a common interface for both the take-up member (mechanical) and the electrical switch (electrical), merging previously separate control systems.
2Ease of operation
If a single operating interface controls multiple components, then user operation is simplified, but the mechanism complexity increases
Solution Approach 1:
The operating device is divided into distinct functional segments: the operating member, the take-up member for mechanical cable operation, and the electrical switch for electrical control. Each segment handles a specific function, allowing complex multi-component control to be broken down into manageable, independent operational paths.
Solution Approach 2:
The operating member acts as an intermediary that translates user input into two different types of control actions. It can directly move the take-up member for mechanical cable tensioning or activate the electrical switch for electronic component control, serving as a mediator between the user and multiple control systems.
3Reliability
If mechanical cable operation is used for component control, then reliable force transmission is achieved, but the ability to operate multiple components simultaneously is limited
Solution Approach 1:
The patent replaces purely mechanical cable operation with a hybrid system. While the first component is controlled through traditional mechanical cable tensioning by the take-up member, the second component is controlled through an electrical switch that generates electrical signals, substituting mechanical force transmission with electrical signal transmission for certain control functions.

AI summary
A bicycle operating device comprises a base member, an operating member, an operating structure, and an operating unit. The operating member is movable relative to the base member between a rest position and an operated position. The operating structure includes a take-up member movable relative to the base member to move a first operation cable in a pulling direction and a releasing direction opposite to the pulling direction. The operating unit is mounted to the base member to operate a second bicycle component in response to an input operation from a user. The operating unit includes an electrical switch and a controller. The electrical switch is configured to receive the input operation from the user. The controller is configured to generate an operation signal to operate the second bicycle component in response to the input operation inputted from the electrical switch.
