Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If partial source information is transmitted for luminance control, then luminance adjustability is improved, but communication reliability deteriorates
Solution Approach 1:
The patent combines source information transmission with channel information transmission into a unified data packet structure. The data packet includes both the first information sequence (channel information for error correction) and the second information sequence (partial source information for luminance control), allowing simultaneous achievement of luminance adjustability and communication reliability through integrated transmission
Solution Approach 2:
The data packet structure serves multiple functions simultaneously: it transmits channel information for error correction, transmits partial source information for luminance control, and enables the receiver to restore original source information. This multi-functional design resolves the contradiction by making a single transmission mechanism serve both luminance control and reliability enhancement purposes
2Illumination intensity
If additional information sequences are transmitted for luminance control, then luminance adjustability is improved, but device complexity increases
Solution Approach 1:
The information to be transmitted is segmented into two distinct sequences: the first information sequence for channel information and error correction, and the second information sequence for partial source information and luminance control. This segmentation allows the system to manage complexity by organizing different functional information into separate, clearly-defined components within the data packet
