Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional rigid fixing structures are used to prevent workpiece shaking, then stability is improved, but adaptability to different workpiece specifications deteriorates

Engineering Contradiction:
Improveworkpiece stabilityVSAvoidadaptability to different workpiece specifications
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent employs elastic members (springs) instead of rigid fixing structures, allowing the fixing member to dynamically adapt to different workpiece dimensions while maintaining stable contact force. The elastic deformation of the springs enables the same fixing structure to accommodate various workpiece specifications without losing stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the physical state of the fixing components from rigid to elastic, allowing parameter adjustment through elastic deformation. This enables the fixing member to adapt its effective dimensions and contact pressure to match different workpiece specifications while maintaining firm fixation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If elastic members are used to provide adjustable positioning, then adaptability is improved, but fixing strength deteriorates

Engineering Contradiction:
Improveadjustable positioning capabilityVSAvoidfixing strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The patent uses composite elastic members (springs) that combine flexibility with sufficient mechanical strength. The elastic material properties are selected to provide both the necessary adaptability for positioning adjustment and the strength required for secure fixation, resolving the contradiction between softness and strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The elastic members are pre-loaded or pre-compressed during assembly to ensure that sufficient fixing strength is maintained from the outset. This preliminary action ensures that the workpiece is firmly secured while still allowing for adaptive positioning adjustments within the elastic range.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If multiple elastic members in intersecting directions are used to fix workpiece in multiple directions, then workpiece stability is improved, but device complexity increases

Engineering Contradiction:
Improvemulti-directional workpiece stabilityVSAvoidnumber of elastic members
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent divides the fixing function into multiple independent elastic members arranged in intersecting directions, with each member responsible for constraining the workpiece in a specific direction. This segmentation allows each component to remain simple while collectively achieving multi-directional stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic members serve multiple functions simultaneously: they provide adaptive positioning, maintain constant contact force, and constrain the workpiece in multiple directions. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in overall device complexity.

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