Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If low voltage is used for LED lamp string control, then power consumption is reduced and battery operation is enabled, but signal transmission loss occurs and light emission stability deteriorates
Solution Approach 1:
The patent transforms the voltage parameter from low voltage to high voltage during signal transmission. The controller boosts the low-voltage control signal to high voltage for transmission through the lamp string, ensuring sufficient signal strength and stability. After transmission, the voltage is stepped down again to drive the LED beads. This parameter transformation resolves the contradiction by enabling both low power consumption (battery operation) and reliable signal transmission.
2Reliability
If additional DC power supply is added to improve voltage, then signal transmission is improved, but device complexity increases
Solution Approach 1:
The patent merges the voltage boosting function into the existing controller unit. Rather than adding a separate DC power supply device, the controller integrates the high-voltage generation and signal modulation functions, combining multiple functions into a single device. This reduces overall system complexity while maintaining reliable signal transmission through the boosted high-voltage signal.
3Adaptability or versatility
If lamp string length is increased to cover larger areas, then application versatility is improved, but signal transmission loss increases
Solution Approach 1:
The patent uses high-voltage signal transmission to extend the effective coverage distance. By transmitting control signals at high voltage, the signal maintains sufficient strength over longer distances, enabling lamp strings to cover larger areas without significant signal loss. This parameter change (voltage level) directly supports both extended coverage and signal integrity.
