Battery Locking Mechanism With Blocking Element Against Impact Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery securing systems in battery compartments, such as those on bicycles, are inefficient and prone to unintentional unlocking, especially under strong impacts, leading to potential battery ejection.
Innovation Solution
A locking mechanism integrated onto the battery itself, comprising rotatable locking elements and a blocking element on the battery compartment, which prevents unintentional unlocking and ensures secure battery retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking mechanism is integrated into the battery compartment with a bolt, then the battery can be secured, but the system becomes complex and expensive to manufacture
Solution Approach 1:
The locking mechanism is inverted from the conventional approach by placing it on the battery rather than in the battery compartment. The battery carries the locking elements that engage with counter-elements in the compartment, reversing the traditional role assignment and simplifying the compartment structure.
Solution Approach 2:
The locking mechanism is divided into separate functional components: locking elements on the battery, counter-elements in the compartment, and a blocking element. This segmentation allows each component to be optimized independently and reduces overall system complexity.
2Reliability
If a conventional bolt-based locking system is used, then the battery can be secured, but the system is prone to unintentional unlocking under strong impacts
Solution Approach 1:
The blocking element is positioned to preemptively prevent the locking elements from disengaging under impact forces. By blocking the unlocking path before impact can occur, the system prevents unintentional unlocking without requiring the locking mechanism itself to resist the full impact force.
Solution Approach 2:
The blocking element acts as a protective measure in place before impact occurs, preventing the harmful effect of impact-induced unlocking by eliminating the possibility of disengagement under shock loads.
3Ease of manufacture
If the locking mechanism is placed on the battery, then manufacturing costs are reduced, but the locking mechanism must be compact and lightweight
Solution Approach 1:
The heavy-duty bolt and bearing components are extracted from the moving battery and left in the stationary battery compartment. Only the essential locking elements remain on the battery, significantly reducing its weight while maintaining security functionality.
Solution Approach 2:
By inverting the locking system placement, the heavy load-bearing components are positioned in the stationary compartment rather than on the moving battery, reducing the weight of the moving object while maintaining structural integrity.
4Weight of moving object
If the blocking element does not need to withstand locking forces, then the system can be made smaller and lighter, but the blocking element must prevent movement of the locking mechanism
Solution Approach 1:
The functional roles are inverted: instead of the blocking element bearing locking forces, the locking elements bear the locking forces while the blocking element only prevents disengagement movement. This role reversal allows the blocking element to be lightweight while maintaining reliability.

AI summary
The invention relates to a system for securing a battery in a battery compartment, comprising a locking mechanism formed on the battery and manually operable, which has at least one locking element that can be engaged with a counter element formed on the battery compartment and associated with the locking element to lock the battery in the battery compartment, and with a blocking element formed on the battery compartment by which the locking mechanism can be blocked in such a way that the battery locked in the battery compartment cannot be unlocked.
