Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a vibration detection instrument with multiple sensors is used, then measurement precision is improved, but device complexity and ease of operation deteriorate due to bulky size and cumbersome attachment

Engineering Contradiction:

Improvevibration detection accuracyVSAvoidattachment ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The base part is designed to change its mechanical properties dynamically during installation. Initially flexible to conform to the counter surface, it becomes rigid after plastic deformation to ensure accurate vibration measurement. This dynamic transition resolves the contradiction between ease of attachment and measurement precision.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The base part undergoes a parameter change from elastic to plastic state during installation. This parameter transformation allows the base to adapt to surface irregularities initially, then maintain a stable, rigid connection for precise measurement, thereby resolving the contradiction between attachment ease and measurement accuracy.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If a vibration detection instrument with multiple sensors is used, then measurement precision is improved, but device complexity increases due to bulky structure

Engineering Contradiction:

Improvevibration detection accuracyVSAvoidinstrument structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The attachment system is segmented into distinct functional parts: the base part for surface adaptation, the attachment screw for securing, and the sensor assembly for measurement. This segmentation allows each component to be optimized independently, reducing overall device complexity while maintaining measurement precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The deformable base part acts as an intermediary between the rigid sensor assembly and the machine surface. It mediates the connection by providing surface adaptation and rigid attachment, allowing the sensor assembly to remain compact and precise without requiring complex mounting structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If traditional attachment methods are used, then reliability of attachment is improved, but ease of manufacture deteriorates due to requirement of machining counter surface

Engineering Contradiction:

Improveattachment securityVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The base part undergoes parameter change from elastic to plastic state during installation, transforming from a flexible form-fitting component to a rigid locked-in structure. This parameter transformation achieves reliable attachment without requiring pre-machined surfaces, improving ease of manufacture while maintaining attachment security.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The base part performs preliminary action by conforming to the counter surface shape before final attachment. This preliminary adaptation eliminates the need for surface machining, and the subsequent plastic deformation during tightening secures the reliable connection, thereby improving ease of manufacture while maintaining attachment reliability.

Inventive Principle:

Principle #10Preliminary action
