Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance electric vehicles face limitations in securing the overall height of the vehicle due to the installation of battery systems in the lower part, leading to instability and inadequate surface pressure maintenance of battery cells, which can result in issues with structural rigidity and effective cooling.
Innovation Solution
A battery system reinforcement apparatus that allows for the mounting of battery modules and cooling blocks in multiple stages, incorporating a case with a lower and upper section, support members, and a cooling hose system to maintain surface pressure and structural rigidity, enabling diverse installation locations and effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery modules are mounted in multiple stages to diversify installation locations, then installation flexibility is improved, but structural stability deteriorates
Solution Approach 1:
The battery system is divided into multiple battery modules mounted in different stages (upper and lower stages), allowing flexible installation in various vehicle locations while maintaining individual module stability through separate support structures
Solution Approach 2:
The battery modules are arranged in vertical stages rather than a single horizontal plane, enabling diverse installation locations within the vehicle's three-dimensional space while maintaining structural integrity through vertical support members
2Adaptability or versatility
If battery modules are mounted in multiple stages to diversify installation locations, then installation flexibility is improved, but structural rigidity deteriorates
Solution Approach 1:
The support members are strategically positioned at asymmetric locations around the battery modules, providing enhanced rigidity where needed while allowing flexible mounting configurations in different vehicle spaces
Solution Approach 2:
The support members act as counteracting structures that compensate for the reduced rigidity inherent in multi-stage configurations, distributing mechanical loads to maintain overall structural strength
3Adaptability or versatility
If battery modules are mounted in multiple stages to diversify installation locations, then installation flexibility is improved, but surface pressure maintenance deteriorates
Solution Approach 1:
The support members serve multiple functions simultaneously: they provide structural support for multi-stage installation flexibility while also maintaining consistent surface pressure on battery cells through their contact design
