Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional illumination devices with simple light sources are used, then the device complexity is low, but the decorative effect is insufficient
Solution Approach 1:
The illumination device is segmented into multiple light emitting sections with different emission patterns (planar light emitting section and linear light emitting section). This segmentation allows each section to contribute differently to the overall decorative effect, resolving the contradiction by creating visual complexity through functional division without requiring a completely complex device structure.
Solution Approach 2:
The patent merges planar light emission and linear light emission into a single integrated illumination device. By combining different light emission patterns in one device, it achieves enhanced decorative effect while maintaining reasonable device complexity, as the multiple functions are integrated rather than requiring separate devices.
2Illumination intensity
If multiple light emitting sections are integrated, then the decorative effect is enhanced, but the device complexity increases
Solution Approach 1:
The illumination device achieves multi-functionality by incorporating both planar and linear light emitting sections that can serve different purposes. The planar section provides broad area illumination while the linear section provides directional accent lighting, allowing one device to perform multiple decorative functions simultaneously, thus enhancing decorative effect without proportionally increasing complexity.
Solution Approach 2:
The patent transitions from simple point or linear light sources to two-dimensional planar light emission. This dimensional change creates richer visual effects and more versatile illumination patterns, enhancing the decorative effect while the planar structure itself provides a framework that manages the complexity of integrating multiple emission types.
