Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional driving control IC with multiple pins is used, then multiple illumination functions can be achieved, but the number of electric wires increases
Solution Approach 1:
The patent merges data transmission and power transmission into a single wire by using time-division multiplexing. The controller alternates between sending data signals and power signals through the same wire, eliminating the need for separate data and power wires. This reduces the total wire count while maintaining full illumination functionality.
Solution Approach 2:
The single wire serves multiple functions: it carries both data signals for controlling illumination patterns and power signals for energizing the light bulbs. The controller is designed to multiplex these different signal types in time, allowing one wire to perform what traditionally required two wires.
2Reliability
If multiple electric wires are used for data and power transmission, then proper control signals can be transmitted, but manufacturing cost increases
Solution Approach 1:
By combining data and power transmission into a single wire, the patent reduces component count and assembly complexity. Fewer wires mean lower material costs, simpler wiring procedures during manufacturing, and reduced labor costs, all while maintaining reliable signal transmission through proper timing control.
3Loss of information
If multiple electric wires are used, then data and power can be transmitted separately, but the manufacturing process becomes more complex
Solution Approach 1:
The controller pre-establishes a timing schedule that alternates between data transmission phases and power transmission phases. This preliminary timing arrangement ensures that data and power signals do not interfere with each other, maintaining data accuracy while simplifying the overall wiring structure and manufacturing process.
