Solution Overview
Problem
Existing methods for addressing light modules in matrix arrangements are either prone to errors due to incorrect assembly or require significant manual effort, leading to incorrect control and display issues in video sequences or optical effects.
Innovation Solution
Light modules equipped with sensors to detect light from adjacent modules, allowing for automatic determination of position and address assignment without the need for direct communication between modules or multiple communication units, using a coordinated light switching process to identify positions and assign addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If addresses are assigned directly before installation or during production, then address assignment is predetermined, but each light module must be attached exactly to the predetermined position, increasing installation complexity and risk of incorrect assembly
Solution Approach 1:
The light module automatically determines its own position and assigns its own address by detecting light from neighboring modules. The control unit receives this self-determined position information and automatically assigns the address, eliminating the need for manual position determination or predetermined address assignment.
2Ease of operation
If manual address assignment is performed after installation, then installation flexibility is maintained, but considerable effort and time are required, and operating errors can occur
Solution Approach 1:
The light module automatically determines its own position and assigns its own address by detecting light from neighboring modules. The control unit receives this self-determined position information and automatically assigns the address, eliminating the need for manual position determination or predetermined address assignment.
Solution Approach 2:
The manual mechanical process of determining position and assigning addresses is replaced by an optical detection system. Sensors detect light from neighboring modules to automatically determine position, and the control unit automatically assigns addresses based on this information.
3Ease of operation
If manual address assignment is performed, then installation flexibility is maintained, but operating errors can occur leading to incorrect activation of light modules
Solution Approach 1:
The light module automatically determines its own position and assigns its own address by detecting light from neighboring modules. The control unit receives this self-determined position information and automatically assigns the address, eliminating the need for manual position determination or predetermined address assignment.
Solution Approach 2:
The system uses feedback from light sensors detecting neighboring module light to automatically determine position and assign addresses. This closed-loop approach ensures that the address assignment accurately reflects the actual physical arrangement of modules.
4Reliability
If communication units are added to each side of light modules for automatic addressing, then address assignment accuracy improves, but device complexity increases due to additional communication units
Solution Approach 1:
The manual mechanical process of determining position and assigning addresses is replaced by an optical detection system. Sensors detect light from neighboring modules to automatically determine position, and the control unit automatically assigns addresses based on this information.
Solution Approach 2:
The existing light emission function of the modules serves a dual purpose: both for displaying video sequences and for position determination during address assignment. The sensors use this existing light function to detect neighboring modules, eliminating the need for separate communication units.
