Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a luminary uses a single light guide for either area or distance lighting, then the lighting function is simple and reliable, but the luminary cannot provide both area and distance lighting simultaneously without manual switching
Solution Approach 1:
The luminary divides the single light guide into multiple segments, each with a different emission angle. The first light guide segment emits light at a first emission angle for area lighting, while the second light guide segment emits light at a second emission angle for distance lighting. This segmentation allows the luminary to provide both lighting modes simultaneously without requiring manual switching or complex mechanical adjustments.
Solution Approach 2:
The patent combines multiple light guide segments with different emission angles into a single integrated luminary structure. By merging the area lighting function and distance lighting function into one device with concurrent emission capability, the luminary achieves versatility without requiring separate devices or complex switching mechanisms.
2Ease of operation
If a luminary requires manual switching between area and distance lighting states, then the device structure can be simpler, but the operation becomes burdensome and time-consuming in critical situations
Solution Approach 1:
The luminary enables continuous simultaneous emission of both area lighting and distance lighting through the permanent light guide segments. This eliminates the need for manual switching actions, allowing the useful lighting function to continue uninterrupted in both modes simultaneously, which is particularly valuable in time-critical emergency or tactical situations.
3Reliability
If a luminary uses permanent light guides with fixed emission angles, then the device is more reliable and requires less maintenance, but the lighting patterns are less adjustable
Solution Approach 1:
The luminary applies the local quality principle by assigning different fixed emission angles to different segments of the light guide. The first light guide segment has a first emission angle optimized for area lighting, while the second light guide segment has a second emission angle optimized for distance lighting. Each segment maintains its specialized function with fixed characteristics, ensuring reliability while the combination provides versatility.
