Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electrical connector parts are arranged laterally offset on fluid coupling parts, then the connection arrangement allows for separate assembly of electrical and fluid components, but the production complexity increases and the overall structure becomes more vulnerable to mechanical stresses

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates the electrical connector parts directly into the fluid coupling parts by forming them as one piece during the molding process. This merging eliminates the need for separate assembly of electrical and fluid components, thereby reducing production complexity while maintaining the adaptability of separate assembly when needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fluid coupling parts are designed to serve multiple functions: they provide fluid connection, electrical connection, and mechanical coupling all in one component. This multi-functionality reduces the overall number of parts and assembly steps, addressing the production complexity issue while preserving versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If electrical connector parts are arranged laterally offset on fluid coupling parts, then assembly flexibility is maintained, but mechanical protection against environmental stresses is reduced
