Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UPS is designed to work in a single mode, then the device complexity is reduced, but the adaptability to different application environments deteriorates
Solution Approach 1:
The patent implements a universal circuit design where the same circuit components can operate in multiple modes (three-input-three-output mode and three-input-one-output mode) by reconfiguring the connection relationships of wiring terminals. The first, second, and third conversion units can function as either input or output depending on the operational mode, eliminating the need for separate dedicated circuits for each mode and achieving multi-functionality without proportionally increasing complexity.
Solution Approach 2:
The patent employs dynamic reconfiguration of circuit connections through switching mechanisms that can change the connection relationships between wiring terminals based on the required operational mode. This dynamic switching capability allows the UPS to adapt between different modes by reassigning the functional roles of conversion units and terminal connections, enabling flexibility without requiring multiple static circuit designs.
2Adaptability or versatility
If additional circuit breakers or wiring blocks are added to enable mode switching, then the adaptability improves, but the manufacturing cost increases
Solution Approach 1:
The patent achieves mode compatibility using the existing conversion units and wiring terminals without requiring additional circuit breakers or wiring blocks. The same hardware components perform multiple functions by changing their connection relationships, which significantly reduces manufacturing costs compared to designs that would require duplicate components for each operational mode.
Solution Approach 2:
The patent merges the functionality of multiple operational modes into a single integrated circuit design. By combining the three-input-three-output and three-input-one-output modes within the same circuit architecture and using the same physical components, the design eliminates the need for separate dedicated circuits, thereby reducing component count and manufacturing cost while maintaining full adaptability.
