Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If active light-emitting components are used with high power consumption for bright illumination, then illumination intensity is improved, but energy efficiency deteriorates due to high lead resistances and voltage fluctuations
Solution Approach 1:
The integrated circuit determines the switching time in advance based on the length of the received serial data stream before actually controlling the light source. This preliminary timing calculation allows all series-connected components to switch simultaneously, preventing voltage fluctuations and improving energy efficiency while maintaining high brightness output.
2Adaptability or versatility
If individual control of active light-emitting components is implemented, then adaptability is improved, but device complexity increases due to numerous supply and return lines
Solution Approach 1:
Multiple supply and return lines are merged into a single serial data stream that is transmitted through the series-connected components. Each component extracts its own control information from this single stream, eliminating the need for complex individual wiring while maintaining individual control capability.
Solution Approach 2:
The single serial data stream serves multiple functions: it provides power transmission, control signals, and timing information to all components simultaneously. This multi-functional approach replaces the need for separate dedicated lines for each function, significantly reducing wiring complexity.
3Reliability
If constant voltage supply is provided to series-connected light-emitting components, then reliability is improved, but energy efficiency deteriorates due to energy dissipation in Zener diodes
Solution Approach 1:
The integrated circuit calculates the switching time in advance based on data stream length before the actual brightness change occurs. This allows all components to switch simultaneously, eliminating voltage fluctuations and improving reliability without requiring energy-dissipating Zener diodes, thus maintaining energy efficiency.
4Device complexity
If brightness values are transmitted via serial data stream, then device complexity is reduced, but transmission errors increase due to fluctuating voltage levels
Solution Approach 1:
The integrated circuit determines the switching time in advance based on the length of the serial data stream before actual brightness modulation. This preliminary timing synchronization ensures that all components switch simultaneously, stabilizing voltage levels during data transmission and preventing transmission errors while maintaining wiring simplicity.
