Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If multiple light sources are used to achieve optimal light output and color, then illumination quality is improved, but device size and complexity increase

Engineering Contradiction:
Improvelight outputVSAvoidnumber of light sources
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent divides the lighting system into multiple independently controllable light source arrays (first light source array, second light source array, third light source array) with different light emission characteristics. Each array can be selectively activated to provide different light colors and luminous flux levels, enabling optimal illumination quality without requiring all light sources to operate simultaneously, thus managing device complexity through modular segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a multi-functional lighting system where the same physical light source arrays can serve multiple functions: providing different light colors (white, yellow, red), adjusting luminous flux levels, and adapting to various external environments. This universality allows the system to achieve optimal light output for different scenarios without requiring separate dedicated light sources for each function, thereby reducing overall device complexity.

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

2Volume of moving object

If light source arrays are densely packed to reduce lamp size, then compactness is improved, but heat dissipation and electrical isolation become more difficult

Engineering Contradiction:
Improvelamp sizeVSAvoidelectrical isolation
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent employs a nested substrate structure where a second substrate is disposed on a first substrate, and light sources are arranged in multiple arrays across these nested layers. This nesting approach enables compact packaging of multiple light source arrays within a reduced lamp volume while maintaining adequate spacing and electrical isolation between arrays through the substrate architecture, thus achieving both compactness and reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If light sources are individually controlled to adjust luminous flux, then adaptability is improved, but control complexity increases

Engineering Contradiction:
Improveluminous flux adjustmentVSAvoidcontrol system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic control of luminous flux by enabling independent activation and intensity adjustment of different light source arrays based on external environmental conditions. The system can dynamically switch between different combinations of light sources (e.g., activating only the first light source array for low-luminous-flux conditions, or combining multiple arrays for high-luminous-flux requirements), providing adaptability while managing control complexity through environment-based decision logic.

Inventive Principle:
Principle #15Dynamics
