Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electromagnetic wave emitting structure is used, then manufacturing is simple, but functionality and quality of operation areas on lateral and back surfaces are limited
Solution Approach 1:
The substrate is divided into a first flat part and a second curved part, allowing different regions to serve different functions. The electromagnetic wave emitting units are segmented into two groups with different pitches, enabling optimized performance for both front and lateral/back surface operation areas.
Solution Approach 2:
Different pitches are applied to different locations: a first pitch for units on the flat part and a second pitch for units on the curved part. This local differentiation optimizes light distribution and viewing angles specific to each surface region, improving overall adaptability without uniform complexity.
2Illumination intensity
If electromagnetic wave emitting units have uniform pitch, then manufacturing is easy, but light distribution quality on curved surfaces is poor
Solution Approach 1:
The patent applies different pitch values to different locations of electromagnetic wave emitting units based on their position on the substrate. Units on the curved part have a second pitch while units on the flat part have a first pitch, optimizing light distribution for each specific region's geometric characteristics.
Solution Approach 2:
The pitch parameter of the electromagnetic wave emitting units is changed based on location. By varying the pitch from the first value (on flat part) to the second value (on curved part), the structure adapts to different surface geometries and achieves superior illumination quality across varied surfaces.
3Area of stationary object
If electromagnetic wave emitting structure covers lateral and back surfaces, then operating area is extended, but structure complexity increases
Solution Approach 1:
The substrate is segmented into distinct flat and curved parts, with the curved part specifically designed to extend electromagnetic wave emission to lateral and back surfaces. This segmentation allows area expansion while managing complexity through functional zonation.
Solution Approach 2:
The structure transitions from a two-dimensional flat substrate to a three-dimensional form with curved surfaces extending in additional spatial dimensions. This enables operation areas on lateral and back surfaces while the pitch variation manages the complexity of this dimensional expansion.
