Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple power storage devices are arranged to provide sufficient power storage capacity, then the power storage capacity is improved, but the overall size and space occupation increase
Solution Approach 1:
The patent combines multiple storage batteries and heat-exchangers into a single integrated power storage device. The device includes a housing containing multiple storage batteries arranged in parallel, with heat-exchangers integrated into the same housing to perform both power storage and thermal management functions simultaneously. This merging of functions reduces the need for separate devices and optimizes space utilization.
Solution Approach 2:
The power storage device is designed with multi-functionality, serving as both an energy storage system and a thermal management system. The heat-exchangers are integrated within the same housing as the storage batteries, allowing the device to simultaneously store electrical energy and dissipate heat generated during charging and discharging operations, thereby eliminating the need for separate cooling devices.
2Reliability
If storage batteries and heat-exchangers are integrally combined into a module, then thermal management efficiency is improved, but space efficiency deteriorates
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement within the housing to optimize the configuration of storage batteries and heat-exchangers. The heat-exchangers are positioned to efficiently contact the battery surfaces while maintaining compact overall dimensions. The housing structure is designed to arrange components in multiple dimensions, maximizing heat transfer surface area while minimizing the external volume occupied by the device.
