1Adaptability or versatility

If adapter apparatus is introduced to bridge RJ-45 and RJ-12 connectors, then legacy sensor compatibility is improved, but device complexity increases

Engineering Contradiction:
Improveconnector compatibilityVSAvoidadapter structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter combines multiple functions into a single compact device: it integrates the RJ-45 connector, RJ-12 connector, and the wiring harness that maps between them into one unified component. This merging approach eliminates the need for separate conversion devices or complex software configuration, reducing overall system complexity despite adding a physical adapter component.
