Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If phase change materials are used to absorb heat and maintain uniform temperature, then thermal management effectiveness is improved, but the risk of heat propagation and chain reactions increases
Solution Approach 1:
The patent divides the thermal management system into multiple independent heat-absorbing units distributed throughout the battery module. Each unit contains phase change materials enclosed in porous particles, creating segmented heat absorption zones that prevent heat propagation between battery cells while maintaining overall temperature uniformity
Solution Approach 2:
The patent introduces porous particles as intermediary carriers that encapsulate phase change materials. These particles act as mediators between the heat-generating battery elements and the phase change materials, controlling heat transfer and preventing direct contact that could lead to heat propagation and chain reactions
2Reliability
If thermal management materials are added to battery modules, then heat treatment capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated component: the porous particles simultaneously serve as structural fillers, phase change material carriers, and thermal management agents. This merging eliminates the need for separate thermal management systems, maintaining battery module simplicity while improving heat treatment capability
Solution Approach 2:
The porous particles perform multiple functions: they provide structural support within the battery module, serve as encapsulation containers for phase change materials, facilitate heat transfer, and maintain electrolyte distribution. This multi-functionality reduces overall system complexity while enhancing thermal management
3Use of energy by moving object
If phase change materials are encapsulated in porous particles, then heat absorption efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs a self-assembly approach where porous particles are mixed with molten phase change materials, allowing the materials to naturally penetrate and fill the porous structure during cooling. This self-service mechanism eliminates complex encapsulation processes while maintaining high heat absorption efficiency through effective material distribution within the porous matrix
