Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED packages are used as light sources to achieve surface light emission, then lighting efficiency is improved, but the number of light emitting devices increases leading to higher cost and greater device complexity
Solution Approach 1:
The patent merges multiple light source modules into a single integrated unit where a first light source module and a second light source module share common structural elements. The first light guide member and second light guide member are positioned adjacent to each other with their light emitting surfaces facing each other, creating a compact configuration that reduces overall device complexity while maintaining efficient light emission.
Solution Approach 2:
The patent implements multi-functionality by having the first light guide member and second light guide member serve dual purposes: each guides light from its own light source while also receiving and guiding light from the adjacent light source module. This cross-guiding capability allows fewer light sources to achieve broader illumination coverage, reducing the total number of light emitting devices required.
2Illumination intensity
If multiple LED packages are used to achieve surface light emission, then illumination intensity is improved, but cost increases due to higher number of devices and circuit implementation complexity
Solution Approach 1:
The patent combines multiple light guiding functions into adjacent modules that share structural and optical pathways. By positioning light guide members with their light emitting surfaces facing each other and enabling cross-guiding of light, the system achieves enhanced surface illumination with fewer independent light sources, thereby simplifying circuit implementation and reducing overall cost.
Solution Approach 2:
The patent utilizes a spatial arrangement where light guide members are positioned in adjacent modules with light emitting surfaces facing each other. This creates additional optical pathways and illumination zones without requiring proportionally more light sources, achieving enhanced surface light emission through efficient spatial utilization rather than simply increasing the number of devices.
3Illumination intensity
If light guide members with emission layers are used to enhance light transmission, then luminance is improved, but the structure becomes more complex
Solution Approach 1:
The patent merges the emission layer functionality into the light guide members themselves, where the first light guide member includes a first emission layer and the second light guide member includes a second emission layer. These emission layers are integrated directly into the light guiding structure, eliminating the need for separate emission components and simplifying the overall device structure while maintaining enhanced luminance.
Solution Approach 2:
The patent employs composite material structures where light guide members are combined with emission layers formed on their surfaces. The emission layers are made of materials that can be excited by light from adjacent modules, creating a composite structure that simultaneously performs light guiding and light emission functions, thereby enhancing luminance without significantly increasing structural complexity.
