Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single focused beam light source is used to illuminate the path ahead, then path illumination effectiveness is improved, but user visibility and conspicuity deteriorate
Solution Approach 1:
The illumination device is segmented into two distinct light sources: a first light source (LED) for diffuse illumination to enhance user visibility, and a second light source (laser) for focused beam projection to illuminate the path ahead. This segmentation allows each light source to perform its specialized function independently, resolving the contradiction between path illumination effectiveness and user visibility.
2Ease of manufacture
If a diffuse light source is used to enhance user visibility, then user conspicuity is improved, but path illumination effectiveness deteriorates
Solution Approach 1:
The device uses separate diffuse and focused light sources instead of relying on a single light source to perform both functions. The first light source provides 360-degree diffuse illumination for user visibility, while the second light source provides concentrated beam illumination for path lighting, eliminating the trade-off between these two functions.
Solution Approach 2:
The illumination device merges two different illumination technologies (diffuse LED lighting and focused laser beam) into a single integrated system. This combination allows the device to simultaneously achieve both user visibility enhancement and effective path illumination without compromising either function.
3Adaptability or versatility
If multiple light sources are added to provide both diffuse and focused illumination, then illumination versatility is improved, but device complexity increases
Solution Approach 1:
The device segments illumination functions into two distinct light sources with different characteristics. The first light source (LED) provides diffuse illumination for visibility, while the second light source (laser) provides focused beam illumination for path lighting. This segmentation achieves illumination versatility while maintaining manageable device complexity through clear functional separation.
