Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dense charging infrastructure with many charging devices is deployed to enable economical electric vehicle charging, then the ease of operation and accessibility for electric vehicle users is improved, but the load on the electrical power distribution system increases significantly
Solution Approach 1:
The patent combines multiple functions into a single charging device: it serves both as a charging station for electric vehicles and as a energy storage unit that can supply power to multiple vehicles simultaneously. The charging device includes an energy storage system that accumulates electrical energy and can distribute it to multiple electric vehicles, thereby reducing the need for multiple separate charging devices and reducing overall grid load.
Solution Approach 2:
The charging device performs preliminary energy storage by accumulating electrical energy in its integrated energy storage system before charging electric vehicles. This allows the device to provide power during peak demand periods without requiring continuous high-capacity grid connection, thereby reducing the overall load on the power distribution system while maintaining charging accessibility.
2Adaptability or versatility
If multiple charging devices are distributed spatially to provide widespread charging coverage, then the versatility and availability of charging options is improved, but the complexity of the charging infrastructure increases
Solution Approach 1:
The charging device is designed as a universal multi-functional unit that can serve multiple electric vehicles simultaneously, provide energy storage, and operate independently or in networked configurations. This multi-functionality allows a single device to replace what would traditionally require multiple specialized charging devices, thereby providing widespread charging coverage while reducing infrastructure complexity.
Solution Approach 2:
The charging device is designed as a modular segmented system with separate functional units for charging, energy storage, and control that can be independently configured and deployed. This segmentation allows the infrastructure to be scaled and adapted to different locations and demand levels without requiring complex integrated systems, thereby improving charging coverage while managing infrastructure complexity.
