Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional insulating block structure is used, then manufacturing is simple, but structural strength is insufficient

Engineering Contradiction:

Improvestructural strengthVSAvoidinsulating block structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The insulating block is divided into multiple segments including a body portion and multiple protruding posts. This segmentation allows each component to contribute to overall structural strength while maintaining manufacturing feasibility through modular construction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protruding posts are designed with asymmetric sector-shaped cross-sections having different radii of curvature. This asymmetric design enhances structural strength and provides different mechanical properties in different directions, while the symmetry between opposing posts enables part sharing.

Inventive Principle:

Principle #4Asymmetry

2Object-affected harmful factors

If contact portions are positioned close together, then device size is reduced, but signal crosstalk increases

Engineering Contradiction:

Improvesignal crosstalkVSAvoidconnector size

Core Design Contradiction:

Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

The sector-shaped protruding posts create localized geometric features that position contact portions at offset locations. This local geometric design reduces signal crosstalk between adjacent contacts while maintaining a compact overall connector size through optimized spatial arrangement.

Inventive Principle:

Principle #3Local quality

3Strength

If more protruding posts are added to insulating block, then structural strength improves, but manufacturing complexity increases

Engineering Contradiction:

Improveinsulating block strengthVSAvoidinsulating block manufacturing

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

Opposing protruding posts are designed with identical sector-shaped cross-sections that can be used interchangeably. This universality allows the same mold or manufacturing process to produce multiple posts, reducing manufacturing complexity while providing enhanced structural strength through the additional posts.

Inventive Principle:

Principle #6Universality (Multi-functionality)
