Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single coupling device is used to connect pipe elements of significantly different outer diameters, then adaptability is improved, but mechanical stability deteriorates

Engineering Contradiction:
Improveadaptability to different pipe diametersVSAvoidmechanical stability of connection
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The coupling device is divided into two separate coupling parts (first coupling part and second coupling part), each optimized for specific pipe diameter ranges. This segmentation allows each part to provide optimal mechanical stability for its designated size range while the system as a whole achieves adaptability across different diameters.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling device achieves universality by combining multiple coupling parts with different geometries into a single system. Each coupling part is designed with specific features (different wall thicknesses, diameters, and positive-locking element configurations) to handle specific pipe diameter ranges, allowing the overall device to connect pipes of significantly different outer diameters while maintaining mechanical stability.

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

2Reliability

If positive-locking elements are used to ensure mechanical stability, then connection reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcomplexity of coupling structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The positive-locking mechanism is segmented into multiple elements distributed around the coupling parts. Instead of one complex locking mechanism, several simpler positive-locking elements are arranged circumferentially, each contributing to overall connection reliability while keeping individual element design simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The positive-locking elements are integrated directly into the coupling parts themselves rather than being separate components. The coupling parts are designed with built-in positive-locking features (protrusions, recesses, or interlocking geometries) that combine the coupling function and locking function into a single unified structure, reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
