Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional power supply circuit is used to connect LEDs in series, then the circuit can operate with low voltage (3-300V), but the voltage received by each LED is insufficient to generate high-voltage electric field for exciting nano-silver
Solution Approach 1:
The power supply circuit is segmented into three independent modules: rectifier circuit for voltage rectification, boost loop for voltage boosting, and combining circuit for voltage synthesis. Each module performs a specific function, allowing the system to achieve high voltage output while maintaining manageable circuit complexity through functional decomposition
Solution Approach 2:
The patent transitions from a single-voltage-source approach to a multi-voltage-level approach by combining first voltage level from rectifier circuit and second voltage level from boost loop. This dimensional change in voltage structure enables achieving high voltage electric field (above 300V) that is necessary for exciting nano-silver to produce silver ions
2Temperature
If quantity of light emitting diodes connected in series is increased to achieve higher voltage, then the working voltage increases, but the circuit complexity and voltage control difficulty increase significantly
Solution Approach 1:
The patent introduces intermediate voltage processing stages (rectifier circuit and boost loop) between the power source and the LED array. Instead of directly connecting many LEDs in series to achieve high voltage, the intermediary circuits transform and boost the voltage to the required level, simplifying the overall circuit configuration and improving voltage control
Solution Approach 2:
The patent changes the voltage parameter through active circuit transformation rather than passive series connection. The rectifier circuit converts AC to DC and establishes a first voltage level, the boost loop increases this to a second voltage level, and the combining circuit synthesizes the final high voltage. This parameter transformation approach allows precise voltage control without increasing the number of LEDs
