Wireless Bicycle Derailleur Power Interface for Flexible Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle derailleurs lack efficient and wireless communication systems for gear shifting, and their power supply mechanisms are limited by direct battery integration, which restricts flexibility and ease of use.
Innovation Solution
A bicycle derailleur system with a wireless communicator, electrical connector receiving portion, and power supply portion that allows for detachable battery charging and wireless control, enabling flexible power management and seamless gear shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless communicator is integrated into the derailleur system, then gear shifting control becomes more convenient and flexible, but device complexity increases due to additional electronic components
Solution Approach 1:
The patent replaces traditional mechanical cable-based gear shifting control with a wireless communication system. The wireless communicator receives signals wirelessly (via radio frequency or other wireless protocols) and translates them into mechanical actuation signals that move the derailleur, eliminating the need for physical cable connections between the control interface and the derailleur mechanism.
Solution Approach 2:
The derailleur system is enhanced with multiple functions: it maintains its primary mechanical gear shifting function while simultaneously integrating wireless communication capabilities, power management functions (battery and charging), and electronic control. This multi-functionality allows a single device to serve both mechanical and electronic purposes.
2Adaptability or versatility
If a detachable battery system with electrical connector receiving portion is implemented, then power supply flexibility and ease of charging improve, but device complexity increases due to additional electrical components
Solution Approach 1:
The power supply system is segmented into separate components: a rechargeable battery unit that can be detached from the main derailleur body. The battery contains its own charging port and electrical connector, allowing it to be charged independently or when attached to the derailleur. This segmentation enables flexible power management where the battery can be removed for charging, replacement, or conservation purposes.
Solution Approach 2:
The electrical connector receiving portion is designed to dynamically accept and disconnect electrical connectors. The connector interface allows for repeated attachment and detachment cycles, enabling the battery to be connected for charging and then disconnected for storage or replacement. This dynamic connection capability provides adaptability in power supply management.

AI summary
A bicycle derailleur includes a base member, a movable member, a linkage structure, a wireless communicator, an electrical connector receiving portion, and a power supply portion. The movable member is movable with respect to the base member. The linkage structure is connected with the base member and the movable member. The wireless communicator is disposed at at least one of the base member, the movable member and the linkage member. The electrical connector receiving portion is configured to receive a connector. The power supply portion is configured to receive electricity from a battery disposed at a location apart from the bicycle derailleur. The electrical connector receiving portion is configured to be electrically connected to the power supply portion. The battery is configured to be charged with electricity through the electrical connector receiving portion and the power supply portion.
