Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each two-pin LED pixel-controlled light emitting diode lamp requires different address codes to be driven correctly, then the lamps can be controlled individually, but the quantity of address codes increases with the number of lamps, making manufacturing more complex
Solution Approach 1:
The system divides the control function into two parts: a controller that generates picture signals and data capture converters that are integrated into the LED lamp strings. This segmentation allows the LED lamps to be manufactured with simple integrated circuits rather than requiring complex individual addressing logic in each lamp, thus reducing manufacturing complexity while maintaining individual control capability.
Solution Approach 2:
The patent introduces data capture converters as intermediary devices between the controller and the LED lamp strings. These converters receive picture signals from the controller and convert them into control signals that drive the LED lamps. This intermediary approach eliminates the need for complex address code management in the LED lamps themselves, simplifying their manufacturing while preserving individual controllability.
2Ease of operation
If control signal lines are used to transmit control signals to LED pixel-controlled light string sets, then the LED sets can be driven correctly, but additional control lines are required beyond the power lines
Solution Approach 1:
The patent makes the power lines serve multiple functions: they simultaneously provide both power transmission and control signal transmission to the LED pixel-controlled light string sets. This multi-functionality eliminates the need for separate control signal lines, reducing the total number of wires required while maintaining full control capability over the LED sets.
Solution Approach 2:
The system merges the power transmission function and control signal transmission function into a single infrastructure using the existing power lines. By combining these two functions that were previously handled by separate lines, the patent reduces wiring complexity and the quantity of materials needed without compromising the ability to drive the LED sets correctly.

AI summary
A two-pin LED pixel-controlled light string system includes a controller, data capture converters, power lines and two-pin LED pixel-controlled light string sets. The controller sends a picture signal to the data capture converters. Each of the number-setting circuits sets a number of the data capture converter. According to the number, the data capture converter captures a captured part of the picture signal. The data capture converter converts the captured part of the picture signal to obtain a light signal. The data capture converter sends the light signal through the power line to the two-pin LED pixel-controlled light string set that the two-pin LED pixel-controlled light string set is in accordance with and electrically connected to the data capture converter, to drive the two-pin LED pixel-controlled light string set to light. Each of the two-pin LED pixel-controlled light string sets lighting together forms a picture representing the picture signal.
