Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining the addresses of each light node in a complex lighting arrangement is challenging and error-prone, especially with the use of splitters, as existing methods lack automated solutions, leading to inefficiencies and potential failures in creating desired light displays.
Innovation Solution
A system utilizing a bus configuration with a controller device that transmits signals and receives responses to assign addresses to light nodes, including those connected through splitters, using a daisy chained address line and splitter signals to dynamically determine the addresses of light nodes in an automated manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual methods are used to determine light node addresses, then the process can be completed with simple equipment, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system enables automated self-addressing of light nodes through a controller that automatically detects and assigns addresses to light nodes in a daisy-chained network, eliminating the need for manual address configuration and reducing both time and human error in the addressing process
Solution Approach 2:
The controller receives feedback signals from light nodes to automatically determine their positions in the network, using the presence or absence of responses to establish addressing sequences without manual intervention, thereby improving accuracy while reducing time consumption
2Adaptability or versatility
If splitters are used to create complex lighting arrangements, then the system becomes more versatile and adaptable, but the addressing process becomes more complex and error-prone
Solution Approach 1:
The system segments the lighting network into multiple branches through splitters, with each branch independently addressable through automated detection, allowing complex tree-structured arrangements to be managed systematically without increasing addressing complexity
Solution Approach 2:
The addressing system transitions from linear sequencing to multi-dimensional addressing by detecting light node positions in a tree structure with multiple branches, enabling the controller to assign addresses based on hierarchical position rather than simple sequential order
3Productivity
If automated addressing is implemented, then the process becomes more efficient and accurate, but the system complexity increases
Solution Approach 1:
The controller automatically performs address assignment by detecting light node responses and generating addresses based on detection sequences, eliminating manual configuration and significantly improving efficiency without requiring complex external addressing equipment
Solution Approach 2:
The controller integrates multiple functions including signal transmission, response detection, address generation, and network configuration into a single device, improving productivity while minimizing the need for additional specialized equipment

AI summary
A device, system, and method determine addresses of nodes for an arrangement including strings that have nodes and a splitter. The system includes a controller device connected to a first string, the first string also connected to the splitter. The system includes a bus configuration connecting the nodes to one another and to the controller device. The controller device transmits first signals to the nodes of the first string and sequentially receives first responses. The controller device assigns addresses to the nodes of the first string. The controller device generates a second signal that defines a path to a splitter output. The controller device sequentially receives second responses from nodes of a second string on the splitter output and then assigns addresses to the nodes of the second string.
