Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional surface emitting element uses a simple concave mirror, then the device complexity is low, but the element cannot impart special characteristics to the light output
Solution Approach 1:
The patent applies local quality by adding specific structures (protrusions or recesses) to only certain regions of the concave mirror surface rather than modifying the entire mirror. This allows the mirror to impart special characteristics to the light output while keeping the overall structure relatively simple and maintaining manufacturing feasibility.
2Reliability
If the concave mirror includes additional structures for special characteristics, then the optical performance is improved, but the manufacturing process becomes more difficult
Solution Approach 1:
The patent segments the concave mirror into a base mirror portion and additional structures (protrusions or recesses). This segmentation allows the base mirror to be manufactured using conventional processes, while the additional structures can be added through separate, simpler processes such as molding or surface treatment, thereby maintaining good manufacturability while achieving improved optical performance.
3Adaptability or versatility
If multiple structures are added to the concave mirror, then the special characteristics are enhanced, but the device complexity increases
Solution Approach 1:
The patent employs asymmetry by designing protrusions or recesses with specific shapes, sizes, and distributions that are not uniformly symmetric across the mirror surface. This asymmetric structure allows the mirror to impart special characteristics such as beam shaping or pattern generation while avoiding the need for overly complex symmetric multi-structure designs.
