Bicycle Battery Holder Lateral Insertion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs for holding additional batteries on bicycles, especially those with 'intube' batteries, face challenges due to limited space, leading to unfavorable placement that restricts movement and makes it difficult to connect cables while riding, as the battery blockage obstructs moving parts or restricts user movement.
Innovation Solution
A compact holding device with a receiving area and a fixing element that allows the battery to be pushed laterally onto it, featuring guides for stable positioning and a snap-on connection, which also integrates an electrical contact device for wireless connection, ensuring secure mechanical and electrical fixation without obstructing the user's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is fixed to the bicycle frame with a bracket, then the battery can be securely mounted, but the battery blocks moving parts and restricts user movement
Solution Approach 1:
The patent positions the battery holder in the rear wheel area, utilizing the vertical and depth dimensions of the bicycle frame rather than horizontal placement. The holder is mounted on the rear dropout or seat stay, allowing the battery to be secured in a location that does not interfere with the crank or user movement, thus resolving the contradiction between secure mounting and ease of operation
Solution Approach 2:
The patent introduces a cable as an intermediary element that connects the battery to the electrical system. The cable is routed through the frame in a way that allows battery removal and installation without requiring disconnection of electrical components, enabling secure mounting while maintaining ease of operation for battery replacement
2Ease of manufacture
If the battery holder is designed with a compact structure, then the battery can be easily mounted, but the electrical connection may be complicated
Solution Approach 1:
The patent combines the mechanical mounting function and electrical connection function into a single integrated battery holder assembly. The electrical contacts are built into the holder structure itself, so that when the battery is mechanically secured in the holder, the electrical connection is automatically established without requiring separate connection steps, thus resolving the contradiction between ease of manufacture and device complexity
Solution Approach 2:
The battery holder is designed with spring-loaded electrical contacts that automatically engage with the battery terminals when the battery is inserted into the holder. This self-service mechanism eliminates the need for manual electrical connection, allowing the battery to be both mechanically mounted and electrically connected through a single insertion action, resolving the contradiction between ease of manufacture and device complexity

AI summary
The present invention relates to a holding device (1) for holding a battery (200), in particular an auxiliary battery, of a bicycle (100) powered by muscle power and/or an electric motor. The holding device (1) comprises a receiving area (2), a mounting area (3), and a fixing element (4). The receiving area (2) is configured to receive a battery (200) and extends in a direction (501). The holding device (1) can be attached to a frame (101) of the bicycle (100) via the mounting area (3). The fixing element (4) is configured to fix the battery (200) in a direction (502) perpendicular to the direction of extension (501). The receiving area (2) is designed such that the battery (200) can be slid laterally onto the receiving area (2) in the direction (502) perpendicular to the direction of extension (501).
