Solution Overview
Problem
Current battery packs face challenges in thermal management and expansion force absorption, leading to reduced battery life due to excessive pressure causing lithium precipitation and irreversible capacity loss, with existing solutions either compromising heat dissipation efficiency or providing insufficient reaction pressure.
Innovation Solution
A temperature control component comprising a first and second side plate, and a buffer plate that extends obliquely to absorb expansion forces, reducing deformation and improving heat dissipation by forming channels for air flow, thereby enhancing the service life of batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid structure is used to maintain structural strength, then structural strength is improved, but expansion forces from batteries cause deformation and reduce battery life
Solution Approach 1:
The side plates are designed with flexible buffer zones that can deform elastically to absorb battery expansion forces. The buffer plate includes buffer zones with reduced thickness that allow controlled deformation, preventing rigid structure damage while maintaining battery contact for thermal management.
Solution Approach 2:
The side plates incorporate regions with changed geometric parameters (reduced thickness in buffer zones) that allow the structure to adapt its mechanical properties. These parameter changes enable the structure to transition from rigid to flexible in specific zones, absorbing expansion forces while maintaining overall structural integrity.
2Force
If buffer materials are added to absorb expansion forces, then expansion force absorption is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The side plates themselves serve dual functions: providing structural support and absorbing expansion forces through their flexible buffer zones. This eliminates the need for separate buffer materials that would insulate heat, as the structural components perform the cushioning function directly, maintaining thermal contact with batteries.
Solution Approach 2:
The side plates are designed to perform multiple functions simultaneously: structural support, thermal management contact, and expansion force absorption. The buffer zones within the side plates provide mechanical cushioning while the plates maintain thermal conductivity pathways, eliminating the trade-off between cushioning and heat dissipation.
3Stability of the object's composition
If the side plates are made rigid to maintain structural integrity, then structural integrity is improved, but the ability to absorb expansion forces deteriorates
Solution Approach 1:
The side plates are segmented into different functional zones: rigid zones that maintain structural integrity and buffer zones that absorb expansion forces. This segmentation allows different parts of the same component to have different mechanical properties, combining the benefits of rigidity and flexibility within a single structure.
Solution Approach 2:
The side plates function as composite structures with regions of different mechanical properties. The combination of rigid and flexible zones within the same component creates a composite effect that provides both structural integrity and expansion force absorption capabilities.
