Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a vacuum device evacuates a chamber to deflect a panel body for defect inspection, then defects can be revealed through deformation, but high evacuation pressure may damage the panel body

Engineering Contradiction:

Improvedefect detection capabilityVSAvoidpanel body damage

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent reduces the evacuation pressure applied by the vacuum device to a lower level that is sufficient to deflect the panel body and reveal defects through deformation, but not so high as to cause damage to the panel body. This parameter optimization resolves the contradiction between defect detection capability and prevention of panel damage.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the panel body is deflected into the chamber for defect propagation, then defects can be revealed, but the testing area may be limited

Engineering Contradiction:

Improvedefect propagation effectivenessVSAvoidtesting area

Core Design Contradiction:

Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent introduces angular orientation as an additional dimension for testing. The base pivot alternates the angular orientation of the base relative to the panel body, creating multiple deflection patterns that expand the effective testing area beyond what a single orientation could achieve, thereby resolving the contradiction between defect propagation effectiveness and testing area coverage.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent makes the base angular orientation dynamic rather than fixed. The base pivot enables the base to alternate between different angular orientations during the inspection process, allowing the panel body to be tested from multiple angles and increasing the homogeneous stress distribution across the entire panel surface.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If the base angular orientation is fixed, then the device structure is simple, but the stress distribution within the panel body is non-uniform

Engineering Contradiction:

Improvebase structure complexityVSAvoidstress distribution homogeneity

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The patent transforms the static base structure into a dynamic one by introducing a base pivot that enables angular orientation changes. This additional degree of freedom allows the system to achieve homogeneous stress distribution across the panel body by alternating between different angular orientations, resolving the contradiction between structural simplicity and stress distribution uniformity.

Inventive Principle:

Principle #15Dynamics
