Solution Overview
Problem
Existing temperature regulation compartments for electrochemical storage modules in vehicles require multiple assembly stages, leading to increased complexity, production costs, and potential infiltration risks, while existing solutions do not optimize heat exchange efficiency.
Innovation Solution
A one-piece tray design with integrated bottom and side walls, combined with a metal or composite external plate featuring channels and disrupting elements, enhances heat exchange and simplifies assembly by reducing components and assembly steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate walls are used to form the compartment, then the compartment can be assembled in stages, but the number of assembly operations increases and production cost increases
Solution Approach 1:
The bottom wall and side walls are merged into a single one-piece tray structure, eliminating the need for multiple assembly operations while maintaining manufacturing flexibility. This integration reduces the number of parts and assembly steps without sacrificing the ability to produce the compartment in a controlled manufacturing environment
2Ease of manufacture
If multiple separate walls are used to form the compartment, then assembly can be done in stages, but the risk of infiltration from outside increases
Solution Approach 1:
The one-piece tray construction eliminates multiple joints and seams where infiltration could occur, significantly improving sealing performance and reliability while still allowing for staged assembly of the complete temperature regulation device
3Ease of manufacture
If multiple separate walls are used, then assembly can be done in stages, but the need for joining materials increases the weight
Solution Approach 1:
The integrated one-piece tray design eliminates the need for joining materials such as adhesives, sealants, or fasteners between wall components, thereby reducing the overall weight of the compartment while maintaining modular assembly capabilities at higher levels
4Temperature
If the contact surface between component and bottom wall is increased, then heat exchange is optimized, but the design complexity increases
Solution Approach 1:
The bottom wall is designed with a substantially planar flat internal face, maximizing the contact surface area with the component in a simple, two-dimensional configuration. This approach optimizes heat exchange efficiency without introducing complex three-dimensional structures or additional design elements
