Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs face challenges in protecting battery cells from external shock and vibration due to increased manufacturing costs and complexity, with the need for additional components and processing steps.
Innovation Solution
A battery pack design featuring a case with injection holes and a shock-absorbing member integrally formed using a double injection process, which includes a prop unit and support units to absorb external shocks and prevent cell movement, made from materials like rubber or urethane, reducing the number of components and processing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate crack preventing member is provided between the battery module and the inner wall of the external case to prevent battery module movement, then the battery cells are protected from external shock and vibration, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The shock absorbing member is integrated directly into the case structure, merging the protective function with the case itself. The case includes a shock absorbing portion that extends inward to contact and support the battery module, eliminating the need for separate crack preventing members while maintaining protection against external shock and vibration.
