Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative lighting systems require lengthy and error-prone setup times and suffer from unacceptable downtime due to the need for readdressing when a lighting device fails, as they rely on addressing schemes that complicate the replacement and integration of new devices.
Innovation Solution
An address-less LED lighting control system where each lighting module receives a digital instruction stream, extracts a portion for local execution, and passes the remainder to the next module, eliminating the need for addressing information and allowing seamless integration and replacement of modules without reprogramming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If addressing schemes are used to control individual lighting devices, then lighting control precision is improved, but system complexity and setup time increase
Solution Approach 1:
The system segments the digital instruction stream into discrete control blocks, where each block contains control information for a specific lighting device. This segmentation allows precise control of individual devices without requiring complex addressing schemes, as each device simply processes its designated control block from the stream.
Solution Approach 2:
The patent extracts the control block for each lighting device from the digital instruction stream and delivers it to the corresponding device. This extraction mechanism eliminates the need for devices to have unique addresses or for the system to perform complex address matching, thereby reducing system complexity while maintaining precise control.
2Measurement precision
If addressing schemes are used to control individual lighting devices, then lighting control precision is improved, but setup time increases
Solution Approach 1:
The control system prepares the digital instruction stream in advance with control blocks pre-organized for each lighting device. This preliminary arrangement eliminates the need for time-consuming address configuration and device identification during setup, allowing the system to begin operation immediately with precise control already in place.
3Measurement precision
If addressing schemes are used, then individual device control is improved, but system reliability decreases due to readdressing requirements
Solution Approach 1:
Each lighting device autonomously processes its designated control block from the digital instruction stream without requiring system-wide readdressing or configuration. This self-service mechanism ensures that individual device control is maintained while eliminating the reliability issues associated with readdressing requirements, as devices simply execute their pre-assigned control blocks.
4Ease of repair
If replacement devices are integrated into the system, then system maintainability is improved, but readdressing time increases
Solution Approach 1:
Replacement lighting devices automatically process their control blocks from the digital instruction stream without requiring readdressing or system reconfiguration. This self-service capability allows devices to be replaced and integrated seamlessly, maintaining system operation while eliminating time-consuming readdressing procedures.
