Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single illumination distribution pattern is used, then the device structure is simple, but the adaptability to different applications is limited
Solution Approach 1:
The optical module is segmented into multiple independent lens groups (first lens group and second lens group), each capable of producing different illumination distribution patterns. This segmentation allows the system to achieve multiple illumination patterns without requiring a completely different optical design for each pattern, thus improving adaptability while controlling complexity.
Solution Approach 2:
The patent implements dynamic switching between different illumination distribution patterns by controlling which lens group is active. The system can dynamically adjust the illumination pattern by selecting different lens groups based on environmental conditions or application requirements, transforming a static single-pattern system into a dynamic multi-pattern system.
2Adaptability or versatility
If multiple optical modules are added to achieve multiple illumination patterns, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
Multiple lens groups are merged into a single integrated optical module structure. The first lens group and second lens group are combined within the same housing and share common mounting structures, allowing the system to achieve multiple illumination patterns while avoiding the complexity of separate optical modules for each pattern.
Solution Approach 2:
The optical module is designed with universal functionality by incorporating multiple lens groups that can each serve different illumination purposes. The same physical space and mounting structure support multiple lens groups, allowing the system to perform multiple illumination functions without proportionally increasing overall device complexity.
3Reliability
If fixed illumination distribution is used, then the manufacturing is simple, but the effectiveness in various applications is reduced
Solution Approach 1:
The optical module is divided into separable lens groups that can be independently manufactured and then assembled. This segmentation allows each lens group to be optimized for specific illumination patterns while maintaining relatively simple individual manufacturing processes, and the assembly process is simplified by using standardized mounting interfaces.
