Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power supply terminals and communication terminals are integrated in the same connector structure, then device integration is improved, but communication quality deteriorates due to noise interference from power supply lines
Solution Approach 1:
The connector housing is divided into a first holding portion for power supply terminals and a second holding portion for communication terminals. These portions are spatially separated and isolated from each other, preventing noise interference while maintaining integration within a single connector structure.
Solution Approach 2:
Different regions of the connector are assigned different functional qualities: the first holding portion is optimized for power supply connections while the second holding portion is optimized for communication connections. This local differentiation ensures that each terminal type operates in its own optimized environment without interference.
2Volume of moving object
If power supply terminals and communication terminals are placed adjacent to each other, then connector compactness is improved, but noise interference increases degrading communication quality
Solution Approach 1:
A partition wall is introduced as an intermediary structure between the first holding portion and the second holding portion. This partition wall physically separates the two terminal groups, blocking the propagation of electromagnetic noise from power supply lines to communication lines while maintaining the compact integrated structure.
Solution Approach 2:
The first and second holding portions are nested within the same connector housing structure, with each portion containing its respective terminals. This nested arrangement achieves compact integration while the internal partitioning prevents noise interference between the nested components.
