Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent power supplies and controlling modules are used to supply power to multiple light source loads, then each load can be independently controlled, but the assembling process becomes complicated and the wiring becomes chaotic
Solution Approach 1:
The patent combines multiple power supplies and controlling modules into a single integrated power supply unit. This integrated unit includes a controlling module that can independently control multiple light source loads, thereby reducing the number of separate components and simplifying the assembling process while maintaining independent control capability.
Solution Approach 2:
The integrated power supply is designed with multi-functional capability to control multiple types of light source loads (such as LED strings, LED modules, or individual LEDs) through a single device. The controlling module can manage different loads simultaneously, making the power supply universal and adaptable to various lighting configurations.
2Adaptability or versatility
If multiple independent power supplies are used, then each power supply can be optimized for specific loads, but the inner wiring becomes complicated and chaotic
Solution Approach 1:
Multiple power supply circuits are merged into a single integrated power supply unit with a unified controlling module. This consolidation reduces the wiring complexity by eliminating the need for separate connections between multiple independent power supplies and their respective loads, while the controlling module maintains the ability to optimize power distribution to different load types.
3Reliability
If separate power supplies are installed at different positions, then each load receives dedicated power, but electromagnetic interference occurs due to complicated wiring
Solution Approach 1:
The patent merges multiple power supply functions into a single integrated unit, which reduces the complicated wiring between separately positioned power supplies and loads. By consolidating the power supply and controlling module into one unit, the source of electromagnetic interference is minimized, while dedicated power delivery to each load is maintained through internal circuit design.
4Productivity
If multiple independent power supplies are used, then power can be supplied to multiple loads simultaneously, but the production cost increases
Solution Approach 1:
The patent merges the functionality of multiple independent power supplies into a single integrated power supply unit. This integrated unit can supply power to multiple light source loads simultaneously through its multi-functional controlling module, thereby reducing the total number of power supply components needed while maintaining the capability to serve multiple loads.
Solution Approach 2:
The integrated power supply is designed with universal functionality to replace multiple specialized power supplies. A single device can control and supply power to different types of light source loads (LED strings, modules, or individual LEDs), reducing component quantity while maintaining multi-load power supply capability.

AI summary
The present disclosure provides a power supply applied to multiple loads, an integrated power supply and a lighting fixture. The power supply comprises a first connector, at least one isolated power supply and at least one non-isolated power supply. The first connector is electrically connected with the at least one isolated power supply and the at least one non-isolated power supply, and is used for being electrically connected with a controller, in order to adjust power states of the at least one isolated power supply and the at least one non-isolated power supply by receiving a power supply control signal from the controller. The at least one isolated power supply and the at least one non-isolated power supply are respectively connected with corresponding load circuit, to supply power to the load circuits, and control working states of the connected load circuits according to the power states thereof.
