Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If only diffused light sources are used, then the lighting is uniform and comfortable, but the lighting intensity is insufficient and the lighting range is limited

Engineering Contradiction:

Improvelighting intensityVSAvoideye strain and discomfort

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The lighting system is segmented into two independent parts: a diffused light source for comfortable ambient lighting and a concentrated light source for intense illumination. This segmentation allows each source to perform its specialized function without interfering with the other, resolving the contradiction between lighting intensity and comfort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges two different types of light sources (diffused and concentrated) into a single lighting unit that can operate independently or simultaneously. This combination enables the system to provide both comfortable uniform lighting and intense focused lighting, eliminating the need to choose between the two.

Inventive Principle:

Principle #5Merging (Combining)

2Illumination intensity

If only concentrated light sources are used, then the lighting intensity is sufficient and the lighting range is extended, but the lighting is uneven and causes eye strain

Engineering Contradiction:

Improvelighting intensityVSAvoidlighting uniformity

Core Design Contradiction:

Illumination intensityVSStability of the object's composition

Solution Approach 1:

The lighting system is segmented into two independent parts: a diffused light source for comfortable ambient lighting and a concentrated light source for intense illumination. This segmentation allows each source to perform its specialized function without interfering with the other, resolving the contradiction between lighting intensity and comfort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the lighting unit have different qualities: the diffused light source provides uniform illumination for general areas, while the concentrated light source provides intense illumination for specific areas. This local differentiation allows the system to achieve both intensity and uniformity where needed.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If a single light source is used, then the device complexity is low, but the lighting functionality is limited and cannot meet diverse needs

Engineering Contradiction:

Improvelighting functionalityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges two different types of light sources (diffused and concentrated) into a single lighting unit that can operate independently or simultaneously. This combination enables the system to provide both comfortable uniform lighting and intense focused lighting, eliminating the need to choose between the two.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lighting unit is designed with multi-functionality to serve different lighting needs: the diffused light source handles ambient illumination, while the concentrated light source handles focused illumination. This universal design allows a single device to perform multiple lighting functions that would otherwise require separate devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)
