Battery Pack Array Retention via Flange and Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securing battery arrays within a battery pack enclosure requires significant packaging space, posing challenges in compact design and stabilization.
Innovation Solution
The use of a flange and recess mechanism, where one of the endwall or endplate provides the flange and the other provides the recess, secured by a fastener that extends through an unthreaded or threaded bore, allowing for efficient stabilization of the battery array within the enclosure with minimal packaging space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional securing methods are used to secure battery arrays within the battery pack enclosure, then the battery arrays are stabilized, but significant packaging space is required
Solution Approach 1:
The flange is received within a recess in the endwall, creating a nested configuration where one component fits into another. This nesting approach secures the battery array while utilizing minimal packaging space, as the securing mechanism does not require additional external space but rather integrates within the existing structure.
Solution Approach 2:
The invention transitions from traditional external securing methods to an internal recess-based securing approach. By moving the securing interface into the recess dimension of the endwall, the solution achieves stabilization without increasing the external packaging volume, effectively utilizing the third dimension (depth of recess) to resolve the space conflict.
2Volume of moving object
If a flange and recess mechanism is used to secure the battery array, then packaging space is reduced, but the device complexity increases
Solution Approach 1:
The flange and recess are integrated as unified components of the battery array and endwall respectively, rather than separate securing elements. This merging reduces the number of discrete parts and simplifies the overall securing mechanism while achieving the same space-saving effect.
Solution Approach 2:
The recess in the endwall automatically provides the securing interface for the flange, eliminating the need for additional securing components or complex assembly procedures. The structure serves its own securing function through the inherent recess-flange interface, reducing device complexity.

AI summary
An exemplary battery assembly includes an endwall, an endplate, and a flange secured within a recess to secure the endwall relative to the endplate. One of the endwall or the endplate provides the flange, and the other of the endwall or the endplate provides the recess.
