Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a mechanical turntable is used to rotate the object being tested, then spherical space sampling data can be obtained, but test efficiency is reduced due to mechanical rotation requirements

Engineering Contradiction:

Improvespherical space sampling data accuracyVSAvoidtest efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces the mechanical turntable system with a fixed probe array system. Multiple probes are distributed in three-dimensional spherical space around the object being tested, and electrical switching is used to activate different probes for omnidirectional sampling. This eliminates mechanical rotation while maintaining measurement capability, thereby improving test efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent transitions from a two-dimensional planar sampling approach to a three-dimensional spherical sampling approach. Probes are arranged in multiple vertical planes at different heights, creating a spherical distribution that enables comprehensive omnidirectional measurement without requiring mechanical rotation of the test object.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a mechanical turntable is used for sampling, then rotation can be achieved, but test precision is affected by turntable rotation precision uncertainty

Engineering Contradiction:

Improverotation capabilityVSAvoidtest precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent eliminates the mechanical turntable entirely and replaces it with a fixed probe array system. The probes are stationary and positioned at known locations in three-dimensional spherical space, eliminating the precision uncertainties associated with mechanical rotation while maintaining the ability to perform omnidirectional sampling through electrical switching.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a turntable structure is used, then sampling can be performed, but the device structure becomes complex and volume increases

Engineering Contradiction:

Improvesampling capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex mechanical turntable subsystem from the sampling device. Instead of using a rotating platform, the design employs a fixed array of probes distributed in spherical space, significantly simplifying the overall device structure while maintaining comprehensive sampling capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical turntable system with an electrical switching system that activates different probes in a fixed array. This substitution eliminates mechanical components, reduces structural complexity, and simplifies the device while maintaining omnidirectional sampling capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If a turntable is used to support the object being tested, then rotation is enabled, but weight capacity is limited by bearing capacity

Engineering Contradiction:

Improverotation functionVSAvoidweight capacity

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The patent replaces the mechanical turntable support system with a fixed probe array system. The probes are mounted on a rigid structure that does not require rotation, eliminating weight capacity limitations associated with mechanical bearings while maintaining the ability to perform omnidirectional sampling through electrical switching of the probe array.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
