Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery packs in electric vehicles occupy significant space due to the need for structural members, which can be reduced by using shear walls coupled with energy storage devices to provide structural support, thereby minimizing the number of bolts required for assembly.
Innovation Solution
The integration of shear walls within the battery pack, coupled with energy storage devices using adhesives, eliminates the need for longitudinal or lateral structural members, allowing for a more compact and lightweight design by distributing forces around the energy storage devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional structural members are used in battery packs, then structural stability is ensured, but the battery pack size and weight increase
Solution Approach 1:
The patent combines energy storage devices with structural members into integrated assemblies where the structural members are disposed within the battery pack and coupled to energy storage devices, eliminating the need for separate longitudinal or lateral structural members. This merging reduces overall battery pack weight while maintaining structural stability through the combined system.
Solution Approach 2:
The structural members serve dual functions: providing mechanical support for structural stability and serving as mounting structures for energy storage devices. This multi-functionality eliminates the need for additional dedicated structural components, reducing overall weight while maintaining strength.
2Strength
If traditional structural members are used in battery packs, then structural stability is ensured, but the battery pack occupies more space
Solution Approach 1:
By merging structural members with energy storage device housings or mounts, the patent eliminates dedicated structural components that would occupy additional space. The structural members are integrated within the battery pack footprint, reducing overall area while maintaining structural stability.
Solution Approach 2:
Structural members perform multiple functions including providing structural support and serving as mounting structures for energy storage devices. This eliminates the need for separate dedicated structural components, thereby reducing the battery pack's occupied space.
3Strength
If multiple bolts are used for assembly, then structural stability is ensured, but manufacturing and installation costs increase
Solution Approach 1:
The patent extracts and eliminates the need for multiple bolts by using adhesive coupling between structural members and energy storage devices. This reduces assembly complexity and manufacturing costs while maintaining structural stability through the adhesive bonding system.
Solution Approach 2:
The patent replaces the mechanical fastening system (multiple bolts) with an adhesive bonding system. This substitution simplifies the assembly process, reduces manufacturing and installation costs, while maintaining structural stability through the adhesive's bonding strength.
