Battery Cell Gap Layout for Compact Collision Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery designs require reserved spaces for electrical safety and collision cushioning, leading to poor space utilization and an inefficient, non-compact structure.
Innovation Solution
Incorporating gaps between the battery cell and the case or bottom cover, with the electrode terminal oriented towards these gaps, which serve as both collision cushions and reserved spaces for electrical safety, enhancing space utilization and structural compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reserved space is arranged between the battery cell and the case for electrical safety and collision cushioning, then safety performance is improved, but space utilization rate deteriorates
Solution Approach 1:
The patent merges the collision cushioning function and electrical safety reserved space function into a single gap structure. The gap between the battery cell and case body simultaneously serves as the cushioning space for impact absorption and the reserved space for electrical safety, eliminating the need for separate reserved spaces and improving space utilization rate while maintaining safety performance.
Solution Approach 2:
The gap structure is designed to perform multiple functions: it acts as both a collision cushioning space and an electrical safety reserved space. By orienting the electrode terminal toward this multi-functional gap, the design ensures that the same spatial region provides both mechanical protection against impact and electrical insulation, thereby resolving the contradiction between safety requirements and space efficiency.
2Reliability
If reserved space is arranged for electrical safety and collision cushioning, then safety performance is improved, but structural compactness deteriorates
Solution Approach 1:
The patent combines the collision cushioning space and electrical safety reserved space into a single integrated gap structure. This merging eliminates redundant spatial arrangements and simplifies the overall battery structure, achieving better structural compactness while maintaining the required safety performance through the multi-functional gap design.
