Elastic Battery Module Connector for Vibration Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules lack the ability to absorb vibrations or shocks from external sources, which can lead to damage or loosening of the module connector.
Innovation Solution
A battery module with a module connector that includes a fastening portion with elastic supports, allowing it to absorb vibrations or shocks by imparting an elastic force in specific directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the module connector is securely fixed to the module case, then the electrical connection is stable, but the connector cannot withstand vibrations or shocks from external sources
Solution Approach 1:
The patent applies beforehand cushioning by incorporating an elastic support member in the fastening portion of the module connector that can elastically deform to absorb vibrations and shocks before they reach the electrical connection terminals. This elastic support member acts as a pre-positioned cushion that protects the connector from external harmful factors while maintaining stable electrical connection.
Solution Approach 2:
The patent applies parameter changes by utilizing the elastic properties of the support member, which can dynamically change its stiffness and deformation characteristics in response to external vibrations and shocks. The elastic support member changes its physical state between rigid (when no vibration occurs) and flexible (when vibration or shock occurs), allowing it to adapt to different operational conditions and protect the connector accordingly.
2Manufacturing precision
If the module connector is rigidly fixed, then manufacturing precision is easier to achieve, but the connector breaks when receiving external loads
Solution Approach 1:
The patent applies segmentation by dividing the fastening portion of the module connector into multiple independent elastic support members. Each support member can independently deform to absorb shocks, while collectively maintaining the connector's positioning accuracy. This segmentation allows the structure to have both rigidity for positioning and flexibility for shock absorption.
Solution Approach 2:
The patent applies composite materials by combining rigid components (connector body, module case) with elastic materials (support members) to create a composite structure. The rigid parts provide manufacturing precision and structural integrity, while the elastic support members provide shock absorption capability, resolving the contradiction between rigidity and flexibility.
