Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs face issues with increased component count, leading to deteriorated assemblability and workability, particularly in assembling and disassembling multiple battery modules, which also results in higher costs and larger volume.
Innovation Solution
A battery module design incorporating a magnet inserted into an insertion groove of a battery case, coupled with a carbon fiber coupling member to enhance coupling force and prevent damage to the groove, and a fixing plate to secure multiple modules, reducing the need for additional coupling components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional coupling components (blot and bracket) are used to assemble battery modules, then the battery modules can be connected, but the number of components significantly increases and assembling/disassembling takes a lot of time
Solution Approach 1:
The patent merges the coupling function into the battery case itself by providing insertion grooves directly on the case, eliminating the need for separate blot and bracket components. The magnet integrated into the case further combines the coupling and fixing functions into a single integrated structure.
Solution Approach 2:
The patent extracts the coupling function from separate components (blot and bracket) and relocates it directly to the battery case through insertion grooves, simplifying the overall structure while maintaining the coupling capability.
2Force
If magnets are inserted directly into insertion grooves of battery cases, then coupling force between battery modules is achieved, but the insertion grooves may be damaged by the magnet
Solution Approach 1:
The patent introduces a coupling member as an intermediary component between the magnet and the insertion groove. This coupling member transmits the coupling force while protecting the insertion groove from direct contact with the magnet, preventing damage to the groove structure.
Solution Approach 2:
The coupling member serves as a protective buffer placed in advance between the magnet and insertion groove, cushioning against potential damage before it can occur during assembly or operation.
3Strength
If multiple coupling components are used to secure battery modules, then the modules are firmly connected, but the volume and cost increase
Solution Approach 1:
The patent combines multiple functions (coupling, fixing, and positioning) into a single integrated battery case structure with insertion grooves and embedded magnets, eliminating the need for separate coupling components and thereby reducing overall volume.
Solution Approach 2:
The battery case is designed with multi-functionality, serving both as the structural housing and as the coupling mechanism through integrated insertion grooves and magnets, eliminating the need for dedicated coupling components.

AI summary
A battery module of the present invention includes: a cell stack in which two or more battery cells are connected in series or parallel; a battery case in which the cell stack is accommodated; a magnet inserted into an insertion groove defined in each of both sidewalls of the battery case; and a coupling member provided between the magnet and the insertion groove to increase coupling force between the magnet and the insertion groove and perform buffering so that the insertion groove is not damaged by the magnet.
