Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a controller is installed in parallel connection with power cords to provide uninterrupted power supply, then the controller can operate continuously, but the relay mechanics become bigger and the system complexity increases
Solution Approach 1:
The patent replaces mechanical relay systems with electronic switching components. The controller uses electronic circuitry to switch the LED lamp on and off, eliminating the need for mechanical relay moving parts. This substitution maintains the uninterrupted power supply function while significantly reducing mechanical complexity and allowing for a compact controller design that can be integrated into the lamp assembly.
2Ease of operation
If batteries are used to power the controller for wireless operation, then the controller can operate independently, but additional cost and safety risks are introduced
Solution Approach 1:
The controller is designed to harvest and store electrical energy from the existing power line that feeds the LED lamp. A rectifier circuit converts the AC power to DC, and a capacitor stores this energy to power the controller's electronic components and wireless communication module. This self-powered approach eliminates batteries entirely, removing fire risks and additional costs while maintaining wireless control capability.
3Adaptability or versatility
If terminal block is changed to a smart one for controller integration, then the control functionality is improved, but an electrician is needed creating extra cost
Solution Approach 1:
The controller is designed with universal compatibility to work with standard lamp holders and existing terminal blocks. It incorporates multiple connection options including parallel and series wiring configurations, allowing installation in various lamp types without requiring specialized smart terminal blocks. This multi-functionality enables do-it-yourself installation while maintaining advanced control features.

AI summary
A controller (116) of an LED illuminating lamp (110) is provided. The controller is configured to replace a starter of a gas discharge tube and it comprises a processing unit (204), pins (200, 202) contactable with counterparts of a starter socket, a power harvesting arrangement (206, 208) operationally coupled between the pins, and a switch (210) electrically coupled between the pins. The processing unit (204) is configured to control the switch between an electrically conducting state for switching light of the LED illuminating lamp on and an electrically non-conducting state for switching light of the LED illuminating lamp off. The power harvesting arrangement is configured to derive power for the controller from electric power fed to the pins irrespective of a state of the switch.
