Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control switch is configured between the LED driver and the lamp through wiring, then the LED lamp can be controlled for on, off or brightness adjustment, but the wiring configuration becomes cumbersome and inconvenient for users
Solution Approach 1:
The patent merges the control switch function directly into the LED driver body, integrating the control circuit board with the driver circuit. This allows the LED driver to directly output control signals to the lamp, eliminating the need for separate external wiring configurations and control switches, thereby simplifying the overall system structure and improving user convenience.
Solution Approach 2:
The LED driver is designed with multi-functionality, serving both as a power supply device and a control device. The control circuit board within the driver can process control signals and directly regulate the LED lamp's operation, making the driver universal in handling both power delivery and control functions, thus eliminating the need for separate control wiring.
2Productivity
If the existing LED driver is connected to an overloaded LED lamp, then the driver can power the lamp, but the driver is easily damaged and its service life is reduced
Solution Approach 1:
The patent incorporates an overload detection and prompting mechanism in the control circuit board. The control circuit continuously monitors the load conditions and provides feedback when the connected LED lamp exceeds the driver's rated power capacity. This feedback function alerts users to disconnect overloaded lamps, preventing damage to the driver and extending its service life while maintaining full power output capability under normal conditions.
