Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If tensegrity structures use cables to connect beams for stress distribution, then structural stability and self-support capability are improved, but device complexity and design calculation requirements increase

Engineering Contradiction:
Improvestructural stabilityVSAvoiddesign complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts the cable connection element from the tensegrity structure and replaces it with direct beam-to-beam contact through connecting elements. This eliminates the need for complex cable tension calculations while maintaining stress distribution through the connecting elements between beams.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent substitutes the cable-mechanism with a direct mechanical contact system where beams rest on each other through connecting elements. This replaces the tensile force mechanism of cables with a compressive contact mechanism, simplifying the mechanical model and design calculations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Stability of the object's composition

If foldable structures use triangular sections for ground stability, then structural stability is improved, but internal volume optimization and adaptability to terrain geometries deteriorate

Engineering Contradiction:
Improveground stabilityVSAvoidterrain adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent employs asymmetric beam configurations where beams can have different lengths and orientations, allowing the structure to adapt to various terrain geometries while maintaining stability. The connecting elements accommodate asymmetric arrangements without requiring symmetric triangular sections.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent creates a dynamic structure where beams can be positioned at varying angles and heights through the connecting elements, enabling adaptation to different terrain conditions while maintaining ground stability through the convex polygon configuration of support points.

Inventive Principle:
Principle #15Dynamics

3Strength

If structures use extensive material and complex assemblies at beam ends, then resistance to compressive and tensile forces is improved, but material requirements and assembly complexity increase

Engineering Contradiction:
Improveforce resistanceVSAvoidmaterial quantity
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The patent segments the force resistance function across multiple beam-to-beam contact points rather than concentrating it at beam ends. Each connecting element distributes local forces, eliminating the need for extensive end assemblies and reducing overall material requirements while maintaining strength.

Inventive Principle:
Principle #1Segmentation
