Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the probe length is fixed, then the device structure is simple, but the probe cannot adapt to objects of varying heights and thicknesses, causing inadequate contact or excessive penetration

Engineering Contradiction:

Improveprobe adaptability to different object heightsVSAvoidprobe adjustment mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The probe length is made dynamically adjustable through a telescopic structure with multiple segments that can extend and retract. This allows the probe to adapt its length to match different object heights and thicknesses, resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The probe is divided into multiple telescopic segments that can be independently adjusted. This segmentation enables flexible length adjustment while maintaining a relatively compact overall structure when retracted, balancing adaptability with device complexity.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If the probe is too short, then the device structure is compact, but the probe cannot make adequate contact with the object surface

Engineering Contradiction:

Improveprobe contact qualityVSAvoidprobe length

Core Design Contradiction:

Measurement precisionVSLength of stationary object

Solution Approach 1:

The telescopic probe can dynamically extend to the required length to ensure adequate contact with the object surface, then retract to a compact size when not in use. This resolves the contradiction between measurement precision requiring sufficient probe length and device compactness requiring short probe length.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If the probe is too long, then the probe can reach distant surfaces, but it penetrates too deeply causing damage to the probe and object

Engineering Contradiction:

Improveprobe contact controlVSAvoiddamage to probe and object

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The adjustable-length telescopic probe allows precise control of the contact depth by extending only to the necessary length. This prevents excessive penetration and damage while still enabling reach to distant surfaces, resolving the contradiction between measurement precision and harm prevention.

Inventive Principle:

Principle #15Dynamics

4Measurement precision

If the detection device has limited adjustability, then the device structure is simple, but it cannot accommodate different orientations and positions required for precise measurement

Engineering Contradiction:

Improvecoordinate adjustment precisionVSAvoidmulti-axial adjustment mechanism

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The detection device incorporates multi-axial adjustment mechanisms that add dimensional freedom for positioning and orienting the probe. This allows precise coordinate adjustments in multiple directions while maintaining a structured approach that manages the complexity of the adjustment system.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

5Measurement precision

If the probe clamping mechanism is insufficient, then the device structure is simple, but the probe cannot be securely held, impacting measurement accuracy

Engineering Contradiction:

Improveprobe clamping stabilityVSAvoidclamping mechanism complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The clamping mechanism uses a V-shaped groove with a curved profile that naturally centers and secures the cylindrical probe. This geometric approach provides stable probe holding through contact at multiple points along the probe surface, achieving secure clamping with a relatively simple V-shaped structure rather than complex multi-component mechanisms.

Inventive Principle:

Principle #14Spheroidality (Curvature)
