Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell blocks for vehicle applications are bulky and heavy due to the need for separate clamping and temperature control elements, which occupy excessive installation space and increase costs.
Innovation Solution
A cell block design where a single temperature control plate serves both as a clamping element and a temperature control medium, reducing the need for additional clamping elements and optimizing thermal management by being thermally coupled to the cells via conductive foils or compounds, allowing for efficient cooling and heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate clamping elements and temperature control plates are used, then reliable clamping and temperature control are achieved, but weight and installation space increase
Solution Approach 1:
The patent combines the clamping element and temperature control plate into a single integrated component. The temperature control plate serves dual functions: it provides thermal management through fluid circulation channels while simultaneously acting as a clamping element that mechanically secures the flat cells in position. This integration eliminates the need for separate clamping structures, thereby reducing overall weight while maintaining both clamping reliability and temperature control effectiveness.
Solution Approach 2:
The temperature control plate is designed as a multi-functional component that performs both thermal management and mechanical clamping functions. By incorporating fluid circulation channels directly into the clamping structure, the plate becomes a universal element that addresses multiple requirements (cooling/heating and structural support) with a single component, thus reducing the total number of parts and overall system weight.
2Stability of the object's composition
If separate clamping elements and temperature control plates are used, then stable cell block formation is achieved, but installation space increases
Solution Approach 1:
The integration of clamping and temperature control functions into a single plate structure reduces the overall footprint of the cell block assembly. By eliminating separate clamping elements and their associated mounting structures, the design minimizes the horizontal and vertical space required for installation while maintaining structural stability through the integrated plate's dual functionality.
Solution Approach 2:
The multi-functional temperature control plate serves as both a thermal management device and a structural clamping element, thereby reducing the total component count and installation space. The plate's design allows it to simultaneously secure multiple flat cells while providing thermal regulation, creating a more compact cell block configuration that requires less installation space.
3Reliability
If multiple separate components are used for clamping and temperature control, then functional reliability is improved, but manufacturing cost increases
Solution Approach 1:
By merging the clamping element and temperature control plate into a single integrated component, the patent reduces the total number of parts that need to be manufactured, inventoried, and assembled. This integration simplifies the manufacturing process, reduces material costs, and lowers assembly complexity while maintaining the functional reliability of both clamping and temperature control through the unified design.
