Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If signals are transmitted through power lines in traditional in-line LED point control lamps, then the structure is simple and wiring is reduced, but the signal stability deteriorates due to interference from power supply fluctuations
Solution Approach 1:
The patent segments the electrical connections by separating power transmission and signal transmission into distinct pathways. The power lines and signal lines are physically separated and connected to different terminals on the LED bracket, preventing electromagnetic interference while maintaining structural simplicity. This segmentation resolves the contradiction by allowing simple wiring without compromising signal stability.
Solution Approach 2:
The patent extracts the signal transmission function from the power transmission pathway. By providing dedicated signal lines separate from power lines, the signal transmission is taken out from the interfering power supply environment. This extraction enables reliable signal transmission while keeping the overall structure simple through shared mounting infrastructure.
2Quantity of substance
If traditional 2-wire carrier point control is used, then the number of wires is minimized, but the maximum number of lamps that can maintain stable signal is limited
Solution Approach 1:
The patent applies segmentation by providing separate power lines and signal lines for each lamp connection. This allows multiple lamps to be connected in parallel with dedicated signal pathways, preventing signal degradation and interference that limits traditional 2-wire systems. The segmentation enables scaling to more lamps while maintaining stable signals.
Solution Approach 2:
The patent introduces dedicated signal lines as intermediary pathways between the controller and multiple lamps. These intermediary signal lines isolate the control signals from power fluctuations, enabling stable communication across a larger number of lamps compared to direct power-line carrier communication.
3Device complexity
If power lines are used to transmit both power and signal, then the device complexity is reduced, but the signal stability and yield of lamp beads deteriorate
Solution Approach 1:
The patent segments the connection structure by providing separate power connecting parts and signal connecting parts on the LED bracket. This segmentation maintains relatively simple device structure while ensuring stable signal transmission by isolating it from power line interference, thereby improving lamp bead yield and reliability.
Solution Approach 2:
The patent applies local quality by providing specialized connection terminals for different functions. The power connecting parts and signal connecting parts have different local characteristics optimized for their respective functions, with signal terminals designed to minimize interference and maximize signal integrity, thus improving overall lamp bead stability.
