Innovation Solution
A system with control devices that integrate a voltage converter and control unit on a common assembly, eliminating the intermediate voltage conversion step and allowing for a compact, space-saving design, where the voltage converter directly converts 230V to 5V, and each control device is designed to be small and attachable to an elongated profile with the LED strands and data line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If control units and voltage converters are separated into distinct components, then each component can be optimized independently, but the overall system size increases and installation space requirements increase
Solution Approach 1:
The patent combines the control unit and voltage converter into a single integrated control device. The control unit includes a microcontroller that directly controls the MOSFETs while the voltage converter circuitry is housed in the same device enclosure, eliminating the need for separate control units and voltage converters, thus reducing overall system size and installation space requirements
2Reliability
If multiple voltage conversion steps are used (230V to 24V, then 24V to 5V), then voltage conversion can be performed in stages, but the system complexity increases and more components are required
Solution Approach 1:
The patent extracts and eliminates the intermediate 24V voltage conversion stage from the system. The voltage converter directly converts 230V to 5V in a single conversion step, removing the unnecessary intermediate step while maintaining reliable voltage conversion through direct switching control of the MOSFETs
3Adaptability or versatility
If control units are distributed separately from LED strands, then control functionality can be modular, but installation becomes more complex and space-consuming
Solution Approach 1:
The patent merges the control unit with the voltage converter housing to create a single integrated control device that is installed directly at the LED strand location. This eliminates the need for separate distributed control units and simplifies installation by reducing the number of components that need to be positioned and connected throughout the system
