Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light emitting chips use a single driving voltage configuration, then the device structure is simple, but the adaptability to different applications and light emitting efficiency are limited
Solution Approach 1:
The light emitting chip is divided into multiple independently controllable light emitting regions (first, second, and third regions), each capable of being driven by different voltages. This segmentation allows selective activation of regions based on application requirements, enhancing adaptability without requiring complete redesign of the entire chip structure.
Solution Approach 2:
The chip structure is designed to support multiple driving voltage configurations simultaneously. The same chip can operate in single-voltage mode for simple applications or multi-voltage mode for complex applications, providing universal functionality across different use cases while maintaining a unified structural framework.
2Productivity
If light emitting chips use multiple driving voltages for sectional driving, then light emitting efficiency and flexibility are enhanced, but the device complexity increases
Solution Approach 1:
The power supply circuit is designed with dynamic voltage output capability, where the multi-output linear power driver can adjust and provide different voltage levels to different light emitting regions based on real-time requirements. This dynamic voltage control enables optimized light emitting efficiency while maintaining circuit manageability through programmable control.
3Productivity
If light emitting elements have different area sizes for optimized performance, then light emitting density is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Different light emitting regions are designed with different area sizes and geometries optimized for their specific functions. The first, second, and third light emitting regions can have different dimensions tailored to their respective light emitting requirements, achieving local optimization of light emitting density while the overall chip manufacturing process remains standardized.
