Hinged Frame-Tube Battery Compartment for Easy Battery Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery compartments in vehicle frame tubes, such as those in bicycles, make it difficult to easily remove batteries while maintaining a seamless integration with the frame design.
Innovation Solution
A battery compartment with a pivotally hinged cover designed as a frame tube section allows easy access for battery insertion and removal, utilizing hinges and a sliding mechanism with locking elements and a spring-loaded operating section for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the battery is mounted inside the frame tube, then the external design of the frame tube is not affected, but removing the battery from the frame tube becomes more difficult
Solution Approach 1:
The frame tube is segmented into a fixed portion and a movable cover portion. The cover can be pivoted open to access the battery while remaining connected to the frame tube through hinges, allowing easy battery removal while preserving the integrated appearance when closed.
Solution Approach 2:
The cover is designed to be dynamic rather than fixed. It can pivot between a closed position (maintaining aesthetic integration) and an open position (enabling battery access). The hinges and locking mechanism allow controlled movement while maintaining structural integrity.
2Ease of operation
If the cover is pivotally hinged to the frame tube, then easy battery removal is enabled, but the closure security may be compromised
Solution Approach 1:
The locking elements are automatically positioned by the sliding cam mechanism before the cover is fully closed. When the cover approaches the closed position, the locking elements engage with the cam's engagement sections, pre-establishing the secure locked state before final contact.
Solution Approach 2:
The sliding cam acts as an intermediary mechanism between the cover and the locking elements. It translates the covering motion into locking/unlocking actions, providing controlled engagement and disengagement of the locking elements without requiring direct manual manipulation.
3Reliability
If locking elements are arranged at the upper edge of the lid, then secure closure is ensured, but the device complexity increases
Solution Approach 1:
The locking elements are integrated into the cover structure itself rather than being separate components. The sliding cam mechanism combines the locking, unlatching, and positioning functions into a single integrated system that operates automatically with cover movement.
Solution Approach 2:
The locking mechanism operates automatically through the sliding cam's interaction with the locking elements during cover opening and closing. The spring-loaded operating section provides self-actuating functionality, eliminating the need for separate manual locking or unlatching actions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and secure removal of batteries while maintaining a seamless integration with the frame tube, preserving the frame's aesthetic integrity and functionality.
Implementation Method 1
The sliding mechanism is preferably spring-loaded, and the cover is released against a spring force. The spring force returns the sliding mechanism to its initial position.

AI summary
A battery compartment integrated into the frame tube of a vehicle, designed to house at least one accumulator, is provided that the compartment has at least one cover, which is formed as a section of the frame tube and pivotally attached to it. This battery compartment allows for easy removal of the accumulator while otherwise integrating seamlessly into the design of the bicycle frame. Furthermore, a manually propelled vehicle equipped with such a battery compartment is shown.
