Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources and individual optical systems are used to selectively illuminate specific areas, then the ability to selectively irradiate light onto specific regions is improved, but the device complexity and manufacturing difficulty increase significantly
Solution Approach 1:
The reflective surface is divided into multiple segmented reflective elements (first reflective surface, second reflective surface, third reflective surface, fourth reflective surface) arranged in a matrix pattern. Each reflective element corresponds to a specific light source and directs light to a specific area, enabling selective area illumination without requiring complete individual optical systems for each light source.
Solution Approach 2:
Multiple light sources (first, second, third, fourth light sources) are combined into a single integrated lighting lamp unit that contains all light sources and the segmented reflective structure. This merging reduces the need for separate optical systems while maintaining the ability to selectively illuminate different areas through individual light source control.
2Adaptability or versatility
If a separate reflective surface and light source are installed for each individual optical system to achieve selective area illumination, then the selective illumination capability is improved, but the weight and manufacturing difficulty increase
Solution Approach 1:
The patent integrates multiple light sources and multiple segmented reflective surfaces into a single lighting lamp assembly. This combined structure eliminates the need for separate assemblies for each light source, significantly reducing overall weight while maintaining the capability to individually control illumination in different areas through the segmented reflective elements.
Solution Approach 2:
The lighting lamp unit is designed as a universal assembly that can perform multiple functions: it can selectively illuminate different areas by controlling individual light sources, and the segmented reflective surfaces work together as a coordinated system rather than requiring separate reflective surfaces for each light source.
3Adaptability or versatility
If multiple light sources and individual optical systems are used to selectively illuminate specific areas, then the selective area illumination is improved, but the manufacturing complexity and ease of manufacture deteriorate
Solution Approach 1:
The reflective surface is segmented into distinct reflective elements (first, second, third, fourth reflective surfaces) that can be manufactured as integrated components of a single lighting lamp. This segmentation enables selective area illumination while the integrated design simplifies manufacturing compared to assembling multiple separate optical systems.
Solution Approach 2:
The patent combines multiple light sources and segmented reflective surfaces into a single manufacturing unit (lighting lamp). This merging allows the entire assembly to be manufactured as one integrated component rather than requiring complex assembly of multiple separate optical systems, significantly improving ease of manufacture.
4Adaptability or versatility
If individual light sources are controlled to turn on/off for specific areas, then the selective area illumination is improved, but the overall light distribution uniformity deteriorates
Solution Approach 1:
Different reflective surfaces are positioned and oriented to direct light from different light sources to different target areas. The first reflective surface directs first light to a first area, the second reflective surface directs second light to a second area, and so on. This local quality approach ensures that each area receives appropriate illumination while maintaining overall distribution uniformity through coordinated design.
Solution Approach 2:
The segmented reflective surfaces are arranged in a matrix pattern with multiple light sources positioned at different spatial locations. By utilizing three-dimensional spatial arrangement and angular positioning of reflective surfaces, the system achieves selective area illumination while maintaining uniform overall light distribution through geometric optimization.
