Battery Module Housing Guide Structure for Shock-Resistant Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems for mobile applications lack the necessary robustness and flexibility to meet the mechanical requirements for portable, shock-resistant, and versatile power supply solutions.
Innovation Solution
A housing design for a battery system comprising multiple individual battery modules with cylindrical lithium-ion cells and electronic modules, where the housing features guide structures such as pins and ribs for secure fixation and protection against vibrations and environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single battery block is used, then the structure is simple, but the flexibility and portability are reduced
Solution Approach 1:
The battery system is divided into multiple individual battery modules (first battery module, second battery module, etc.) that can be independently arranged and configured within the housing. Each module contains battery cells and can be selectively positioned or removed, providing flexibility while maintaining a manageable structured through the housing's organized compartments.
2Reliability
If battery modules are loosely arranged in the housing, then the installation is simple, but the protection against vibrations and shocks is insufficient
Solution Approach 1:
The housing is pre-equipped with guide structures (guiding ribs, guiding grooves, positioning pins) during manufacturing that automatically guide and secure battery modules into the correct positions. This preliminary preparation ensures both easy installation (modules snap into place) and reliable vibration protection (modules are firmly positioned).
Solution Approach 2:
Guide structures act as intermediary elements between the housing and battery modules, providing both positioning and securing functions. These intermediate components facilitate easy module installation while simultaneously ensuring robust protection against vibrations and shocks.
3Strength
If the housing is made more robust for mobile use, then the shock resistance improves, but the weight increases
Solution Approach 1:
The housing is constructed from composite materials combining plastic and metal components. The plastic housing halves provide lightweight protection, while strategically placed metal elements (positioning pins, reinforcing ribs) add localized strength and shock resistance without significantly increasing overall weight.
4Reliability
If guide structures are added for secure fixation, then the vibration protection improves, but the manufacturing complexity increases
Solution Approach 1:
Multiple functions are merged into single components: the housing structure itself incorporates guiding ribs and positioning features, while battery module housings integrate corresponding grooves and pins. This consolidation reduces the number of separate parts and simplifies manufacturing processes despite the enhanced fixation capabilities.
