Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems require significant effort and infrastructure changes to implement digital control systems, especially when upgrading or retrofitting, as they necessitate laying additional data lines, which can be impractical or impossible in existing buildings.
Innovation Solution
A lighting system with control units that generate and transmit digital control commands wirelessly to operating devices, using sensors with independent power supplies and wireless communication standards like Bluetooth, eliminating the need for extensive data line installation and allowing for easy integration of sensors and control elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate data lines are laid for digital control command transmission, then control precision and coordination are improved, but installation effort and complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical/electrical system of separate data line installation with a wireless communication system. Control commands are transmitted via wireless signals (such as radio frequency communication) between the control unit and luminaires, eliminating the need for physical data line infrastructure while maintaining digital control precision and coordination capabilities.
2Adaptability or versatility
If lighting systems are upgraded to digital control, then functionality and coordination are improved, but infrastructure changes and costs increase
Solution Approach 1:
The control unit is designed to perform multiple functions: it generates control commands, transmits them wirelessly to luminaires, receives status information from the luminaires, and coordinates their operation. This multi-functional design eliminates the need for separate dedicated infrastructure components for each function, reducing overall system complexity while maintaining enhanced functionality and adaptability.
3Ease of manufacture
If wireless communication is used for control commands, then installation effort is reduced, but reliability and coordination may be compromised
Solution Approach 1:
The patent implements a feedback mechanism where luminaires transmit their status information back to the control unit via wireless communication. The control unit uses this feedback to monitor system state, detect potential issues, and adjust control commands accordingly, thereby maintaining system reliability and coordination without requiring physical data lines.
