Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvedevice integrationVSAvoidcommunication quality
Core Design Contradiction:
Adaptability or versatilityVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improveconnector compactnessVSAvoidnoise interference
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #7Nested doll (Nesting)
