Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a grounding structure with multiple grounding terminals and shielding sheets is used, then the shielding effect is improved, but the installation complexity increases

Engineering Contradiction:
Improveshielding effectVSAvoidinstallation complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines multiple grounding terminals into a single integrated grounding terminal structure that spans across the insulating housing. This single grounding terminal incorporates multiple contact points and integrates the functions of what would otherwise require multiple separate terminals and shielding sheets, thereby maintaining the shielding effect while significantly simplifying the installation process

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The grounding terminal is designed with multi-functional capabilities: it provides grounding contact through its body, establishes electrical connection via the grounding pin, and maintains structural stability through the clamping structure. This universal design allows a single component to perform multiple functions that would traditionally require separate components, reducing installation complexity while preserving shielding effectiveness

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

2Object-affected harmful factors

If a grounding structure with overlapping shielding sheets is used, then the shielding effect is improved, but the installation precision requirement increases

Engineering Contradiction:
Improveshielding effectVSAvoidoverlap precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent extracts the complex overlapping shielding sheet structure and replaces it with a simplified grounding terminal design. The grounding terminal directly contacts the insulating housing and establishes grounding connections without requiring multiple layers of shielding sheets to be precisely overlapped and positioned, thereby eliminating the high precision overlap requirement while maintaining shielding effectiveness

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using multiple shielding sheets that require precise overlap from the outside in, the invention inverts the approach by using a single grounding terminal that establishes grounding from the inside out. The grounding terminal's clamping structure secures it firmly to the insulating housing, ensuring stable electrical contact without requiring external shielding sheets to be precisely aligned

Inventive Principle:
Principle #13The other way round (Inversion)
