Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate positive and negative terminals are provided for each semiconductor converting element, then electrical connection reliability is improved, but device size increases
Solution Approach 1:
The patent combines multiple terminals (positive terminals, negative terminals, control terminals) into a single integrated terminal structure. The terminal includes a common negative terminal shared by multiple semiconductor converting elements and integrated control terminals, eliminating the need for separate positive and negative terminals for each element while maintaining reliable electrical connections.
Solution Approach 2:
The common negative terminal serves multiple functions: it acts as the negative terminal for multiple semiconductor converting elements simultaneously and provides a shared reference potential for control signals. This multi-functional design reduces the total number of terminals needed while ensuring reliable electrical connections.
2Adaptability or versatility
If a separate control board is provided for inputting control signals, then control signal input capability is improved, but device complexity increases
Solution Approach 1:
The patent integrates control terminals directly into the terminal structure of the semiconductor module device. The control terminals are formed as integral parts of the terminal assembly, allowing control signals to be input directly through the terminal without requiring a separate control board, thereby simplifying the overall device structure.
Solution Approach 2:
The terminal structure serves dual purposes: it provides electrical connections for power transmission (positive and negative terminals) and simultaneously accepts control signals (control terminals). This multi-functional terminal design eliminates the need for separate control hardware while maintaining full control signal input capability.
3Adaptability or versatility
If multiple separate components are provided for terminals and control boards, then functional capability is improved, but number of parts increases
Solution Approach 1:
The patent merges multiple separate components (positive terminals, negative terminals, control terminals) into a single integrated terminal structure. The terminal is formed as one unified component that incorporates all necessary electrical connection points, significantly reducing the total number of parts while maintaining all required functional capabilities.
Solution Approach 2:
The integrated terminal structure performs multiple functions simultaneously: it provides power connection points (positive and negative terminals) and control signal input points (control terminals) all within a single component. This multi-functional design reduces the number of parts needed while preserving complete functional capability.
