Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional vibration management solutions are used, then vibration isolation performance is achieved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvevibration isolation performanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring element is divided into distinct functional segments: loop sections for vibration isolation and fastening portions for mounting. This segmentation allows each part to be optimized independently while maintaining overall performance, resolving the contradiction between performance and manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring element serves multiple functions simultaneously: it provides vibration isolation, structural support, and mounting capabilities through integrated fastening portions. This multi-functionality eliminates the need for separate components, reducing manufacturing complexity while maintaining performance.

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

2Reliability

If multi-directional vibration isolation is achieved, then performance in all vibration directions is improved, but structural complexity increases

Engineering Contradiction:
Improvevibration isolation performance in all directionsVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring element employs asymmetric loop sections with different geometries oriented in different directions. This asymmetric design allows the structure to provide vibration isolation in multiple directions while maintaining a relatively simple overall form, resolving the contradiction between multi-directional performance and structural complexity.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The spring element utilizes three-dimensional loop configurations that provide vibration isolation capabilities in multiple spatial directions. By designing loops that extend in different dimensions, the element achieves multi-directional performance without requiring multiple separate components.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If simple and economic manufacturing is achieved, then ease of manufacture is improved, but vibration isolation performance may be compromised

Engineering Contradiction:
Improvemanufacturing simplicity and costVSAvoidvibration isolation performance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The spring element is constructed from thin plate material that is cut or cast into the final shape. This approach allows complex three-dimensional loop structures to be manufactured from simple flat stock using standard cutting or casting processes, maintaining both manufacturing simplicity and vibration isolation performance.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The vibration isolation performance is controlled by adjusting geometric parameters of the loop sections (such as loop size, thickness, and orientation) rather than changing the fundamental manufacturing process. This allows performance optimization while maintaining simple and economic manufacturing methods.

Inventive Principle:
Principle #35Parameter changes
