Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional coaxial cable and connector components are manufactured and assembled individually, then manufacturing flexibility is maintained, but manufacturing complexity increases and assembly becomes difficult

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the coaxial cable and connector into a single integrated contactor structure where the core part, insulation part, and shield part are formed as one piece. This eliminates the need for separate assembly of multiple components, thereby reducing manufacturing complexity and assembly difficulty while maintaining manufacturing flexibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated contactor structure performs multiple functions simultaneously: the core part provides signal transmission, the insulation part provides electrical isolation, and the shield part provides electromagnetic shielding. This multi-functional design eliminates the need for separate components, simplifying both manufacturing and assembly processes.

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

2Reliability

If rigid components are used in the contactor, then structural stability is improved, but connection reliability decreases due to inability to accommodate surface tolerances and shape differences

Engineering Contradiction:
Improveconnection reliabilityVSAvoidstructural stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent changes the physical state of the contactor components from rigid to elastically deformable. This parameter change allows the core part, insulation part, and shield part to deform elastically during insertion and connection, enabling them to accommodate surface tolerances and shape differences between mating components, thereby improving connection reliability while maintaining structural stability through elastic recovery.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If elastically deformable components are used, then connection reliability is improved through close contact, but manufacturing precision requirements increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddimensional precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent employs the flexible shell concept by making the core part, insulation part, and shield part elastically deformable. This flexibility compensates for minor dimensional variations and surface irregularities that occur during manufacturing, reducing the stringency of manufacturing precision requirements while ensuring reliable close contact between mating components.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The elastic deformability of the contactor components provides beforehand cushioning against dimensional tolerances and shape differences. The elastic deformation capability acts as a buffer that absorbs manufacturing variations, ensuring reliable connection without requiring extremely tight manufacturing precision.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Productivity

If multiple separate components are used, then functional specialization is improved, but assembly time and manufacturing cost increase

Engineering Contradiction:
Improveassembly efficiencyVSAvoidcomponent quantity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (coaxial cable and connector) into a single integrated contactor structure. This merging reduces the number of components from multiple separate parts to one unified structure, thereby eliminating assembly steps and significantly improving assembly efficiency and productivity while reducing manufacturing cost.

Inventive Principle:
Principle #5Merging (Combining)
