Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the luminaire is changed to produce different illumination light patterns, then the light pattern adaptability is improved, but the device complexity and cost increase

Engineering Contradiction:
Improvelight pattern adaptabilityVSAvoidluminaire complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs dynamic adjustment of the optical lens assembly, where the lens can move between different positions (first position and second position) to change the light pattern. This dynamic mechanism allows a single luminaire to adapt to different illumination needs without requiring multiple fixed luminaires, thereby improving light pattern adaptability while avoiding the complexity of multiple luminaire configurations.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple luminaires are used to achieve different light patterns, then the light pattern versatility is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvelight pattern versatilityVSAvoidoperation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple light patterns into a single luminaire by integrating an optical lens assembly that can switch between different optical states. Instead of operating multiple separate luminaires to achieve different patterns, the merged design allows a single device to produce various light patterns through internal lens positioning, significantly improving ease of operation while maintaining light pattern versatility.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the optical lens assembly structure is simplified, then the device complexity is reduced, but the light pattern adjustment capability deteriorates

Engineering Contradiction:
Improveoptical lens assembly complexityVSAvoidlight pattern adjustment capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The optical lens assembly is segmented into distinct functional components: an optical lens with specific refractive index, a light source, and a support structure. The lens itself is divided into different regions (first lens region and second lens region) with different optical properties. This segmentation allows each component to be optimized independently while working together to provide multiple light patterns, achieving adaptability without excessive overall complexity.

Inventive Principle:
Principle #1Segmentation
