Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a mounting device uses a rigid body portion to provide structural strength, then the structural strength is improved, but the vibration dampening capability deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidvibration dampening
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The body portion is designed with an elastically deformable bend that allows dynamic flexibility while maintaining overall structural integrity. This enables the mounting device to adapt to vibrations rather than resisting them rigidly, thereby providing both strength and vibration isolation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The material properties of the body portion are selected to exhibit elastic deformation characteristics within a specific range. The bend is designed to deform elastically under vibration loads, absorbing energy while maintaining structural strength, thus resolving the contradiction between rigidity and vibration dampening.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If a mounting device incorporates complex vibration isolation mechanisms, then the vibration dampening capability is improved, but the device complexity increases

Engineering Contradiction:
Improvevibration dampeningVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The vibration isolation function is merged into the body portion itself through the elastically deformable bend, rather than being implemented as a separate mechanism. This integration achieves vibration dampening without adding complexity to the overall device structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastically deformable bend provides automatic vibration isolation through its inherent elastic properties, requiring no additional control systems or complex mechanisms. The structure serves its own vibration dampening needs through passive elastic deformation.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If the body portion is made fully rigid to simplify manufacturing, then the ease of manufacture is improved, but the vibration isolation capability deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidvibration isolation
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Instead of making the entire body portion rigid or flexible, only the bend region is designed with elastically deformable characteristics. This localized approach maintains ease of manufacture for most of the structure while providing vibration isolation where needed, balancing manufacturing simplicity with functional performance.

Inventive Principle:
Principle #3Local quality
