Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional opaque enclosure is used to contain electromagnetic energy, then safety is improved, but visibility into the interior space deteriorates

Engineering Contradiction:

Improveelectromagnetic energy containmentVSAvoidvisibility into interior space

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The enclosure is divided into different portions with different optical properties. The transparent portion allows visibility while the overall enclosure maintains electromagnetic containment. This local differentiation resolves the contradiction by allowing visibility in specific areas without compromising overall safety.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The enclosure uses composite material structures that combine transparency with electromagnetic filtering capabilities. The transparent portion is constructed from materials or coatings that selectively transmit visible light while blocking harmful electromagnetic wavelengths, thus achieving both visibility and safety simultaneously.

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The filtering is applied selectively to specific wavelength ranges rather than uniformly across all wavelengths. The transparent portion filters harmful electromagnetic wavelengths while preserving transmission of visible light wavelengths, thus maintaining both safety and acceptable color appearance/visibility.
