Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional IPT systems use separate power converters for each energy source, then independent control of energy sources is achieved, but system complexity and cost increase
Solution Approach 1:
The patent combines multiple power converter functions into a single integrated power converter that handles multiple energy sources (primary energy source and alternative energy source) and the IPT system. This single converter performs functions that traditionally required separate converters, thereby reducing system complexity and component count while maintaining the ability to independently control energy flow from each source through its respective controller.
2Adaptability or versatility
If additional power converters are added to integrate alternative energy sources, then energy source integration is enabled, but system reliability decreases
Solution Approach 1:
By merging the power conversion functions into a single integrated converter, the patent reduces the number of components that could potentially fail. The integrated design maintains adaptability to integrate multiple energy sources while improving reliability by eliminating the need for multiple separate power converters and reducing overall system complexity.
3Ease of operation
If multiple power converters are used for multiple energy sources, then individual control is achieved, but cost increases
Solution Approach 1:
The patent merges multiple power converter units into a single integrated power converter, significantly reducing component count and system cost. Individual control of each energy source is maintained through dedicated controllers that communicate with the integrated converter, allowing the system to achieve both cost efficiency and operational flexibility.
4Productivity
If traditional IPT systems use discrete magnetic couplers with super-capacitor banks, then dynamic EV charging is enabled, but system complexity increases
Solution Approach 1:
The patent integrates the alternative energy source and its power conversion functionality into the existing IPT system architecture through a single integrated power converter. This approach enables dynamic EV charging capabilities while avoiding the need for separate super-capacitor banks and discrete magnetic couplers, thereby reducing overall system complexity compared to traditional dynamic charging solutions.
