Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid clamping elements (rivets, bars) are used to secure straps, then the straps are firmly fixed to the support, but the strap base may be prematurely broken due to lack of deforming characteristics

Engineering Contradiction:
Improveclamping strengthVSAvoidstrap base durability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent changes the physical state and mechanical properties of the clamping system by using an elastic platform instead of rigid clamping elements. The platform's elasticity allows it to deform under load, distributing stress away from the strap base while maintaining secure fixation. This parameter change from rigid to elastic resolves the contradiction between clamping strength and strap base durability.

Inventive Principle:
Principle #35Parameter changes

2Strength

If straps are clamped tightly to prevent excessive spacing, then secure fixation is achieved, but the distribution uniformity becomes difficult to control

Engineering Contradiction:
Improvefixation securityVSAvoidstrap distribution uniformity
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The patent employs a flexible elastic platform that can conform to the support surface and uniformly distribute straps. The flexibility of the platform allows it to adapt to variations in strap positioning while maintaining secure fixation, thereby achieving both fixation security and distribution uniformity without requiring precise manufacturing tolerances.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of manufacture

If conventional rigid clamping systems are used, then assembly is straightforward, but the system lacks deforming characteristics to prevent strap base breakage

Engineering Contradiction:
Improveassembly simplicityVSAvoidstrap base longevity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The invention changes the mechanical parameter of the clamping system from rigid to elastic, allowing the platform to deform and absorb stress. This elastic deformation capability prevents stress concentration at the strap base, extending its life while maintaining assembly simplicity through the integrated platform design that requires no complex clamping mechanisms.

Inventive Principle:
Principle #35Parameter changes
