Battery Module Connecting Assembly With Molded Insulating Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connecting piece in battery modules is prone to separation from the insulating plate due to vibration stress, posing a safety risk.
Innovation Solution
A connecting assembly is designed where the connecting piece is embedded in an integrally molded insulating plate, forming a non-detachable integral structure that restricts movement and enhances stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting piece is detachably connected to the insulating plate, then the ease of assembly is improved, but the reliability of connection deteriorates due to separation under vibration stress
Solution Approach 1:
The connecting piece and insulating plate are merged into a single integral structure through injection molding, eliminating the detachable connection interface that causes separation under vibration. The connecting piece is embedded within the insulating plate during the molding process, creating a unified component that cannot separate.
Solution Approach 2:
The connecting piece is nested within the insulating plate structure. The injection molding process forms the insulating plate around the connecting piece, with the connecting piece embedded in a cavity or recess of the insulating plate, creating a nested configuration where the inner component is protected and secured by the outer structure.
2Stability of the object's composition
If the connecting piece and insulating plate are formed as an integral structure, then the connection stability is improved, but the manufacturing complexity increases
Solution Approach 1:
Two separate components (connecting piece and insulating plate) are merged into a single integral structure through injection molding. This combining of functions into one manufacturing process creates structural stability while the molding technology manages the complexity of forming integrated features.
Solution Approach 2:
The insulating plate serves multiple functions: it provides electrical insulation, structural support, and houses the embedded connecting piece. The injection molding process simultaneously creates all these features in one operation, making the manufacturing process universal and efficient despite the complex integrated structure.
