Bicycle Battery Assembly Installation Aid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of bicycle batteries within the frame, particularly in the down tube, is complex due to the need for precise alignment and fixing, which involves manual adjustment and use of screws through openings, making it cumbersome and requiring additional stoppers for proper positioning.
Innovation Solution
A bicycle battery assembly with an integrated installation aid at the battery opening of the down tube, featuring a boss and complementary locating/abutment surfaces, facilitates easy adjustment and securing of the battery using screws, allowing for both longitudinal and lateral adjustments without additional frame fastening, thus simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is fixed inside the frame tube using screws through openings, then the battery can be securely fastened, but the installation process becomes complex requiring manual adjustment and alignment
Solution Approach 1:
The battery housing is equipped with self-aligning features including a locating surface that automatically aligns with the frame tube opening and integrated fixing elements that self-position during insertion, eliminating the need for manual alignment adjustments
Solution Approach 2:
The fixing elements and locating surfaces are pre-configured on the battery housing before installation, so that when the battery is inserted into the frame tube, the alignment features automatically engage without requiring preliminary manual adjustment of screw positions or battery orientation
2Ease of operation
If the bicycle is turned upside down for battery insertion, then the battery can be easily inserted, but manual positioning must be maintained while screwing
Solution Approach 1:
The battery housing includes self-aligning locating surfaces and integrated fixing elements that automatically position the battery correctly during insertion, eliminating the need for manual positioning maintenance and reducing installation time
3Manufacturing precision
If a stopper is installed inside the frame tube to prevent over-insertion, then the battery positioning is constrained, but the stopper installation itself is complex
Solution Approach 1:
The positioning function previously requiring a separate stopper component is merged into the battery housing itself through integrated locating surfaces and positioning features that prevent over-insertion without requiring frame tube modifications
Solution Approach 2:
The stopper function is extracted from the frame tube and transferred to the battery housing, eliminating the need to modify the frame tube structure while maintaining the over-insertion prevention function

AI summary
A bicycle battery assembly comprises a bicycle frame tube, such as a down tube. A battery is adapted to be inserted through a battery opening in the longitudinal direction of the bicycle frame tube. For allowing for a simple fixing of the battery to the bicycle frame tube, in particular by means of screws, an installation aid is connected to the battery and/or the bicycle frame tube, in particular in the area of the battery opening. The installation aid allows for an easy installation since in particular screw holes in the bicycle frame tube are flush with threaded bore holes in the battery.
