Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling LEDs in pattern cutouts embedded in floor, ceiling, and wall panels face issues with voltage drop and interference due to long cable lengths, leading to malfunctions such as loss of brightness and incorrect color mixing, especially when using large numbers of LEDs with high current requirements.
Innovation Solution
The solution involves an LED control arrangement using a voltage source, an LED controller that generates and converts SPI signals into optical signals, and multiple LED converters to extend the range without voltage drop or interference, incorporating a motherboard with a processor for setting light properties via Bluetooth or WiFi, and an evaluation circuit for fire alarm integration, allowing seamless data transmission and fault-tolerant operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If long cable lengths are used to extend the control range, then the coverage area is improved, but voltage drop and signal distortion occur leading to LED malfunctions
Solution Approach 1:
The patent replaces the electrical signal transmission system with an optical signal transmission system. Instead of transmitting control signals through electrical cables over long distances (which causes voltage drop and signal distortion), the system uses optical fibers or light-based transmission media. This substitution eliminates the electrical resistance and signal degradation issues inherent in long electrical cable runs, allowing extended control range without compromising LED operation reliability.
2Productivity
If a high number of LEDs are controlled, then the illumination coverage is improved, but the current increases requiring large conductor cross-sections
Solution Approach 1:
The patent substitutes electrical current transmission with optical signal transmission to control multiple LEDs. By using optical fibers or light-based communication instead of high-current electrical conductors, the system can control a large number of LEDs without requiring proportionally large conductor cross-sections. The optical transmission carries control signals rather than power, eliminating the direct relationship between LED quantity and conductor size requirements.
3Length of stationary object
If electrical signals are transmitted over long distances, then the control range is improved, but signal distortion and interference occur
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission to maintain signal integrity over long distances. Optical signals transmitted through optical fibers or light-based media are immune to electromagnetic interference and signal distortion that plagues electrical signals over long cable runs. This substitution preserves data accuracy and control signal fidelity while extending the achievable transmission distance.
