Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wired lighting control systems are used, then reliable power and control signals are provided, but installation complexity and flexibility are reduced due to wiring requirements
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. The LED driver and control devices communicate via Bluetooth Low Energy (BLE) mesh network, eliminating the need for physical control wiring while maintaining reliable signal transmission for dimming and control functions.
Solution Approach 2:
The patent introduces a wireless communication intermediary (BLE mesh network) between the control devices and LED driver. This intermediary enables signal transmission without direct physical connections, allowing flexible installation while maintaining system reliability through established wireless communication protocols.
2Adaptability or versatility
If conventional lighting control systems are used, then basic dimming control is achieved, but advanced control features and large-scale network support are limited
Solution Approach 1:
The patent implements a universal control system based on BLE mesh network that supports multiple control functions including dimming, scene setting, remote control, and automation. The system can accommodate various control devices (smartphones, tablets, wireless switches) and scales to support large numbers of LED drivers, providing multi-functional control without requiring separate systems for each function.
3Length of moving object
If wireless control is implemented without mesh topology, then simple point-to-point control is achieved, but operational range and network scalability are restricted
Solution Approach 1:
The patent transitions from simple point-to-point wireless communication to a mesh network topology, adding the dimension of multi-hop signal routing. This enables signals to traverse through multiple intermediate devices, extending the operational range beyond direct communication limits and allowing scalable network expansion while managing complexity through standardized mesh protocols.
