Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sets of color generators are used to generate different color lights, then the color perception testing capability is improved, but the device complexity and cost increase

Engineering Contradiction:
Improvecolor perception testing capabilityVSAvoidnumber of optical elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple color generation functions into a single integrated system. The light source generates multiple light beams that are directed through a reflective grating to different areas of a single optical switch, which then routes them to different areas of a single light mixer. This merging approach eliminates the need for multiple separate color generators while maintaining the ability to produce various color lights for comprehensive color perception testing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single light source serves multiple functions by generating different color lights through the reflective grating and optical switch system. The light mixer also performs multiple functions by combining light beams in different configurations to produce various color outputs. This multi-functionality allows the system to conduct diverse color perception tests without requiring separate dedicated color generation devices for each test type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If manual inspection methods are used for color blindness diagnosis, then the operational simplicity is maintained, but the inspection time and eye fatigue increase

Engineering Contradiction:
Improveoperational simplicityVSAvoidinspection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces manual inspection methods with an automated optical testing system. The light source, reflective grating, optical switch, and light mixer work together as an automated system that can rapidly present different color stimuli to the test subject without requiring manual intervention. This automation significantly reduces inspection time while maintaining operational simplicity through electronic control rather than manual manipulation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If prolonged inspection time is used to ensure accurate color perception testing, then the testing completeness is improved, but the eye fatigue and result deviation increase

Engineering Contradiction:
Improvecolor distinction accuracyVSAvoideye fatigue
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The automated system can implement periodic testing cycles where color stimuli are presented in a structured sequence. The optical switch can rapidly cycle through different color combinations, allowing the test subject to respond to multiple stimuli in quick succession without prolonged exposure to single colors. This periodic presentation maintains testing completeness while reducing eye fatigue through varied and brief stimulus exposure.

Inventive Principle:
Principle #19Periodic action
