Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OLED light sources are used to achieve complex three-dimensional light emitting surfaces and personalized aesthetic shapes, then the lighting functions and visual effects are improved, but the manufacturing costs increase significantly
Solution Approach 1:
The patent segments the light emitting surface into multiple discrete LED elements arranged in a matrix pattern. This segmentation allows complex three-dimensional shapes to be achieved through selective activation and arrangement of individual LED elements, while maintaining compatibility with standard LED manufacturing processes, thereby reducing costs compared to OLED solutions.
Solution Approach 2:
The patent applies local quality by varying the distribution, density, and activation states of LED elements across different regions of the light emitting surface. This enables personalized aesthetic shapes and complex three-dimensional effects in specific areas while using simpler configurations in other areas, optimizing manufacturing efficiency and reducing overall costs.
2Ease of manufacture
If traditional LED lighting devices are used, then manufacturing costs are reduced, but the ability to create complex three-dimensional light emitting surfaces and display information messages is limited
Solution Approach 1:
The patent transitions from traditional two-dimensional LED arrangements to a three-dimensional configuration by stacking multiple LED layers and using varying emission angles. This dimensional enhancement allows complex three-dimensional light emitting surfaces to be created using cost-effective discrete LED elements rather than expensive OLED technology.
Solution Approach 2:
The patent implements dynamic control of LED elements through independent addressing of matrix elements, enabling the light emitting surface to change shapes, patterns, and three-dimensional configurations over time. This dynamic capability allows complex visual effects and information display while maintaining the cost advantages of discrete LED technology.
3Manufacturing precision
If high definition and resolution light emitting surfaces are created with constant pitch, then the visual quality is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs universal mounting structures and standardized interconnection methods that work across all LED elements in the matrix. This universality maintains constant pitch and high definition quality while simplifying manufacturing processes and reducing device complexity through standardized components and assembly procedures.
