Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rigid clamp structure is used to hold the flat wiring member, then the holding position is fixed and stable, but the clamp cannot adapt to changes in wiring member thickness

Engineering Contradiction:
Improveadaptability to thickness changesVSAvoidholding stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The press part is designed to pivot about a hinge axis, transforming a static rigid clamp into a dynamic structure that can adjust its position. The press part rotates from an initial position to a pressed position, enabling adaptation to different wiring member thicknesses while maintaining stable contact through the pressing action.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pressing force parameter is adjusted by the elastic press piece, which deforms elastically under the wiring member. This allows the clamp to adapt to thickness variations by changing the contact force parameter while maintaining reliable holding through controlled elastic deformation.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a rigid clamp structure is used to hold the flat wiring member, then the structure is simple and strong, but it cannot firmly hold the wiring member when thickness varies

Engineering Contradiction:
Improvefirm holding capabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The hinge-connected press part introduces dynamic adjustment capability without significantly complicating the overall structure. The simple rotational movement about a hinge axis provides adaptability while maintaining structural integrity and firm holding capability across different thickness conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic press piece automatically adjusts to the wiring member thickness through elastic deformation, eliminating the need for complex adjustment mechanisms. The structure serves itself by using the inherent elastic properties of the press piece to adapt and maintain firm holding.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the press part is made elastic to adapt to thickness changes, then adaptability improves, but the pressing force may become insufficient

Engineering Contradiction:
Improvethickness adaptationVSAvoidpressing force
Core Design Contradiction:
Adaptability or versatilityVSForce

Solution Approach 1:

The elastic press piece changes its deformation parameter according to the wiring member thickness, allowing full contact while maintaining adequate pressing force. The elastic deformation enables adaptation without sacrificing force, as the piece naturally adjusts its shape to match the thickness variation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The press part dynamically adjusts its position and contact force through the hinge mechanism. As the press part rotates to the pressed position, it applies force that adapts to the thickness while the elastic press piece ensures continuous contact with sufficient pressing force.

Inventive Principle:
Principle #15Dynamics
