Detachable Bicycle Frame Connector for Hub Motor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for bicycles directly connect with wheel hub motors during installation, causing inconvenience and potential misalignment issues, and do not allow for easy detachment or maintenance.
Innovation Solution
A detachable electrical connector system for bicycle frames featuring a fixed seat and an inserted seat with a core shaft installation hole, where the inserted seat is movable and equipped with electrically conductive structures, allowing for manual or tool-assisted connection and disconnection with the wheel hub motor using a quick-release core shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical connector is directly connected during wheel hub motor installation, then the electrical connection is established, but misalignment issues and inconvenience occur
Solution Approach 1:
The patent introduces an intermediary mechanism (the movable inserted seat with conductive structure) that mediates between the fixed electrical connector and the wheel hub motor. This intermediary allows for alignment adjustment and prevents direct misalignment issues, while also enabling the fool-proof connection feature where the connector cannot be improperly installed.
2Ease of repair
If the electrical connector is directly connected during installation, then electrical connection is achieved, but maintenance and detachment become difficult
Solution Approach 1:
The electrical connector is segmented into two distinct parts: a fixed seat that remains installed on the bicycle frame and an inserted seat that can be easily removed. This segmentation enables simple detachment for maintenance while keeping the overall structure relatively simple through the use of basic mechanical components.
3Ease of operation
If the inserted seat is made movable for easy connection, then ease of operation improves, but connection stability may be compromised
Solution Approach 1:
The inserted seat is designed to be movable during the connection process, allowing users to easily insert and adjust it. Once connected, the system transitions to a stable state where the movable seat is secured in position, providing both ease of operation and connection stability.

AI summary
The present invention illustrates an electrical connector for detachable installation in a bicycle frame (20), which is detachably installed in a lower fork of a bicycle frame (20) and includes a fixed seat (40) and an inserted seat (50). The fixed seat (40) is installed in the aforementioned lower fork. The fixed seat (40) is hollow in shape. The inserted seat (50) is inserted in the fixed seat (40) movably back and forth. The inserted seat (50) has a first end surface (51), a second end surface (52) opposite to the first end surface (51), and a core shaft installation hole (53) penetrating through the first and second end surfaces (51,52). The first end surface (51) of the inserted seat (50) is provided with a set of electrically conductive structure (54). As a result, when a wheel hub motor (60) is installed on the bicycle frame (20), the electrical connector is able to be pushed to be electrically connected with the wheel hub motor (60) as needed.
