Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light emitting diode is used, then the device structure is simple, but the lighting flexibility and adaptability are limited
Solution Approach 1:
The light emitting chip is divided into multiple light emitting diodes (first LED, second LED, third LED) with different light distribution characteristics. Each LED segment has a specific light distribution curve optimized for particular viewing angles, allowing the overall chip to provide adaptable lighting effects across different directions while maintaining a unified chip structure.
Solution Approach 2:
Different regions of the light emitting chip are designed with different light emitting properties. The first, second, and third light emitting diodes are positioned at different locations and oriented at different angles, creating local variations in light distribution that collectively achieve versatile lighting performance throughout the chip.
2Adaptability or versatility
If multiple light emitting diodes with different light distribution curves are integrated into a single chip, then lighting adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple light emitting diodes with different light distribution curves are merged into a single light emitting chip. The first, second, and third LEDs are integrated on the same substrate with their respective anodes and cathodes connected to corresponding electrodes, enabling coordinated control while simplifying the overall device structure compared to using separate components.
Solution Approach 2:
The light emitting chip is designed as a multi-functional component that can simultaneously provide different light distribution patterns. By integrating multiple LEDs with distinct light distribution characteristics into one chip, the device achieves universal applicability for various lighting scenarios without requiring multiple separate components.
3Illumination intensity
If light emitting diodes are arranged to provide different light distribution curves, then brightness control at different angles is improved, but the device complexity increases
Solution Approach 1:
The light emitting diodes are arranged asymmetrically on the chip substrate with different orientations and positions. The first LED is oriented at a first angle, the second LED at a second angle, and the third LED at a third angle, creating asymmetric light distribution patterns that enable precise brightness control at different viewing angles while maintaining a relatively simple chip structure.
