Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a sensor is attached to a curved surface, then the application scope of sensors is expanded, but folds occur and sensitivity is affected

Engineering Contradiction:

Improveapplication scopeVSAvoidsensitivity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The sensor is divided into multiple independent sensing units that can be separately attached to different regions of the curved surface. Each sensing unit maintains its structural integrity and sensing capability independently, preventing fold-induced sensitivity degradation while enabling attachment to complex curved geometries.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from planar sensor attachment to three-dimensional curved surface attachment by designing sensing units with spatial adaptability. The sensing units are configured to conform to curved surfaces in multiple dimensions, expanding application scope while maintaining sensing performance through proper spatial orientation and structural design.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a sensor is attached to a curved surface, then the application scope of sensors is expanded, but manufacturing complexity increases

Engineering Contradiction:

Improveapplication scopeVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor system is segmented into standardized sensing units that can be manufactured independently using conventional processes. These modular units are then assembled onto curved surfaces, simplifying manufacturing by avoiding the need to manufacture entire curved sensors as single complex components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sensing units are designed with universal attachment characteristics that enable them to be applied to various curved surfaces with different radii and geometries. This universality reduces manufacturing complexity by using the same basic sensing unit design across multiple applications rather than creating custom sensors for each curved surface.

Inventive Principle:

Principle #6Universality (Multi-functionality)
