Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If single-unit power converters are connected in parallel using conventional connection methods, then large-capacity power converter systems can be constructed, but the installation and wiring process requires lots of time and labor
Solution Approach 1:
The connection apparatus is divided into modular components including a lead-in board with opening/closing means and separate connecting means for each power converting unit. This segmentation allows independent connection and disconnection of individual units without affecting the entire system, significantly reducing installation and maintenance time while enabling parallel connection of multiple units to achieve large capacity
Solution Approach 2:
The lead-in board is pre-configured with opening/closing means that can automatically connect or disconnect power lines when cover is opened or closed. This preliminary arrangement of connection mechanisms eliminates the need for time-consuming manual wiring during installation and allows rapid system assembly by simply mounting the power converting units
2Adaptability or versatility
If conventional connection methods are used for parallel power converters, then systems can be assembled, but the wiring process is labor-intensive and complex
Solution Approach 1:
The connection apparatus merges the lead-in board with integrated opening/closing means and the connecting means of power converting units into a unified connection system. This integration allows simultaneous connection of multiple power converting units through a single automated action (opening/closing the cover), eliminating complex manual wiring operations while maintaining parallel connection capability
Solution Approach 2:
The opening/closing means on the lead-in board automatically performs the connection and disconnection functions when the cover is opened or closed. This self-service mechanism eliminates the need for manual wiring operations, reducing labor intensity and simplifying the installation process while enabling versatile parallel connections of multiple units
