Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power supply and dimming control lines are used for each lighting equipment, then reliable control is achieved, but the number of lines and power outlets increases, leading to higher installation costs and labor costs
Solution Approach 1:
The patent combines power supply and dimming control functions into a single integrated controller. The controller includes both a power supply circuit and a dimming control circuit, allowing it to provide both power and control signals through one connection point, thereby reducing the number of lines and outlets while maintaining reliable control.
Solution Approach 2:
The controller is designed with multi-functionality, serving both as a power supply device and a dimming control device. It can connect to the lighting load through a single power outlet and provide both electrical power and control signals, eliminating the need for separate control wiring.
2Ease of operation
If multiple power outlets are installed to support both power supply and dimming control, then adequate power and control are provided, but installation time and labor costs increase
Solution Approach 1:
By merging power supply and control functions into one device, the installation process requires only a single power outlet connection rather than multiple outlets, significantly reducing installation time and labor requirements.
Solution Approach 2:
The system uses modular controllers that can be independently installed and configured. Each controller is a self-contained unit with standardized connections, allowing for quick installation and easy replacement without affecting other parts of the system.
3Extent of automation
If a centralized control system is used to manage large area lighting, then synchronized control is achieved, but system complexity and maintenance costs increase
Solution Approach 1:
The control system is divided into independent modular controllers, each managing a specific lighting zone or fixture. This segmentation allows synchronized control across multiple devices while keeping each controller simple and self-contained, reducing overall system complexity.
Solution Approach 2:
The controller includes a signal adjustment circuit that acts as an intermediary between the control signal input and the dimming control output. This circuit standardizes and conditions signals, enabling synchronized control across multiple devices while simplifying the control architecture.
