Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a rigid electrode device is used, then measurement precision may be improved, but skin adhesion and comfort deteriorate due to inability to adapt to body shape variations

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidskin adhesion

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent employs an elastic member that can dynamically transform its shape to adapt to different body contours while maintaining electrode contact. The elastic member transitions from a stored state to a transformed state that conforms to the body surface, ensuring both measurement precision and skin adhesion across various body shapes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The elastic member changes its physical parameters (shape, position) during transformation to accommodate body shape variations. By adjusting the transformable range and shape of the elastic member, the device maintains consistent electrode-skin contact while adapting to different anatomical structures, resolving the contradiction between rigid measurement requirements and flexible skin adhesion.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the elastic member has a large transformable range, then adaptability to various body shapes improves, but electrode movement and measurement accuracy deteriorate

Engineering Contradiction:

Improveadaptability to body shapesVSAvoidmeasurement accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The elastic member is designed with differentiated local properties: the first point allows a relatively large transformable range to adapt to body shape variations, while the second point maintains a relatively small transformable range to stabilize electrode position. This local differentiation enables simultaneous achievement of adaptability and measurement precision.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the clamp electrode device is made rigid, then structural stability improves, but pain and discomfort increase due to uneven pressure distribution

Engineering Contradiction:

Improvestructural stabilityVSAvoidpain and discomfort

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes an elastic member that functions as a flexible element within the clamp structure. This flexible component distributes pressure evenly across the contact surface while maintaining overall structural stability, thereby reducing pain and discomfort without compromising the device's structural integrity.

Inventive Principle:

Principle #30Flexible shells and thin films

4Ease of operation

If the elastic member is highly flexible, then comfort and adaptability improve, but electrode position stability and measurement reliability deteriorate

Engineering Contradiction:

Improvecomfort and adaptabilityVSAvoidelectrode position stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The elastic member exhibits localized flexibility: the first point region provides high flexibility for comfort and adaptability, while the second point region maintains relative rigidity to ensure electrode position stability. This spatial differentiation of mechanical properties resolves the contradiction between comfort and reliability.

Inventive Principle:

Principle #3Local quality
