Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery stacks in electric vehicles face challenges in stability due to their spatial size and dead weight, requiring external stabilization elements that add weight and occupy installation space.
Innovation Solution
A module housing for stackable battery modules that incorporates internal and external battery receptacles on a base section, allowing for force transmission between battery units, reducing the need for external stabilization and enhancing the inherent rigidity of the battery stack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If external stabilization elements are used to ensure battery stack stability, then stability is improved, but weight and installation space increase
Solution Approach 1:
The patent merges the stabilization function into the battery module housing itself by integrating stiffening elements and connection structures directly into the housing design. This allows the housing to perform both protective enclosure and structural stabilization functions simultaneously, eliminating the need for separate external stabilization elements and reducing overall weight.
Solution Approach 2:
The housing structure is designed with multi-functionality, serving as both the protective enclosure for battery units and the primary stabilization structure for the battery stack. The integration of stiffening elements and connection structures into the housing enables it to fulfill multiple structural roles, reducing the need for additional dedicated stabilization components.
2Stability of the object's composition
If external stabilization elements are used to ensure battery stack stability, then stability is improved, but installation space is consumed
Solution Approach 1:
The stabilization structures are merged with the housing design, integrating stiffening elements and connection structures directly into the housing. This integration eliminates the need for separate external stabilization components, thereby preserving installation space while maintaining structural stability.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously provides protective enclosure and structural stabilization. By incorporating stiffening elements and connection structures into the housing itself, the design maximizes space utilization without requiring additional external stabilization elements.
3Stability of the object's composition
If additional components are added to stabilize the battery stack, then stability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the housing structure itself. The housing integrates stiffening elements and connection structures, merging the protective enclosure function with the structural stabilization function. This reduces the number of separate components and simplifies the overall battery stack structure.
Solution Approach 2:
The housing is designed as a universal component that performs multiple functions: protective enclosure, structural support, and stabilization. This multi-functionality reduces the need for additional dedicated components, thereby simplifying the overall device complexity while maintaining stability.
