Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two circuits are used per lamp group with current-limiting resistors, then the string light can be operated, but the working current and power consumption increase
Solution Approach 1:
The patent merges two separate circuits into a single circuit by combining the rectifier and booster functions into one integrated circuit. This eliminates the need for parallel circuit connections and current-limiting resistors, thereby reducing power consumption while maintaining operability.
Solution Approach 2:
The patent changes the voltage parameter from standard AC voltage to boosted voltage (higher than AC output voltage). By increasing the voltage parameter, the working current is reduced, which directly lowers power consumption while keeping the string light operational.
2Quantity of substance
If multiple current-limiting resistors are used, then the LED lamps can be driven, but the number of LED lamps is limited and production cost increases
Solution Approach 1:
The patent combines multiple functional components (rectifier, booster) into a single circuit, eliminating the need for multiple current-limiting resistors. This reduces device complexity and allows more LED lamps to be driven in the same circuit.
Solution Approach 2:
The patent extracts and eliminates the current-limiting resistors from the circuit by using a boosted voltage approach. This removes unnecessary components, simplifying the circuit structure and enabling support for more LED lamps.
3Reliability
If two circuits connected in parallel are used, then the string light can operate, but the working current increases
Solution Approach 1:
The patent merges two parallel circuits into a single series circuit, changing the current flow path. This reduces the working current while maintaining the ability to operate the string light.
Solution Approach 2:
The patent changes the circuit configuration parameter from parallel to series, and simultaneously increases the voltage parameter. This parameter change reduces the working current while preserving operability.
