Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If sensing type lighting devices are used independently, then automatic lighting control is achieved, but installation cost increases significantly
Solution Approach 1:
The system divides the sensing function into a dedicated sensing type lighting device that acts as a controller, while other lighting devices function as executors. This segmentation allows only one device to have the expensive sensing component, reducing overall installation cost while maintaining automatic control capability across the group.
Solution Approach 2:
The sensing type lighting device serves multiple functions: it acts as both a lighting device and a control center for the entire group. By integrating control functionality into the sensing device, the system eliminates the need for separate control equipment, reducing overall system cost.
2Area of stationary object
If multiple sensing type lighting devices are deployed, then coverage area increases, but lighting interference and inconsistency occur
Solution Approach 1:
The sensing type lighting device receives sensing information from its sensors and uses wireless communication to coordinate with other lighting devices in the group. This feedback mechanism ensures that all devices work in unison based on the sensed environment, eliminating lighting interference and maintaining consistency across the expanded coverage area.
Solution Approach 2:
The sensing type lighting device acts as an intermediary between the sensing elements and the other lighting devices. It processes sensing information and transmits control signals to coordinate the operation of all devices, ensuring consistent lighting performance across multiple units.
3Adaptability or versatility
If additional control functions are added to lighting devices, then functionality increases, but device complexity and cost increase
Solution Approach 1:
The sensing type lighting device is designed as a multi-functional unit that combines lighting, sensing, and wireless communication capabilities. By integrating these functions into a single device rather than adding separate control systems, the overall system complexity is reduced while maintaining versatile control functionality.
