Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized lighting control system is used, then all lighting devices can be controlled from one location and energy costs are reduced, but the system becomes vulnerable to failures and limitations in scalability
Solution Approach 1:
The patent divides the centralized lighting control system into multiple independent distributed control units, each capable of autonomous decision-making. This segmentation eliminates the single point of failure in centralized systems while maintaining coordinated control across the lighting network.
Solution Approach 2:
The system implements dynamic control where lighting devices can adapt their operation based on real-time sensor data and network conditions. Each device possesses intelligent control capabilities that allow the system to reconfigure dynamically in response to failures or changes, enhancing reliability.
2Extent of automation
If a centralized lighting control system is used, then automated lighting control is achieved, but the system is limited in scalability and complexity increases when adding new devices
Solution Approach 1:
By distributing control functions to individual lighting devices rather than requiring all devices to connect to a central controller, the system enables easy scalability. New devices can be added to the mesh network without increasing central controller complexity or requiring complex commissioning procedures.
Solution Approach 2:
Each lighting device in the distributed system possesses autonomous control capabilities and can independently make decisions based on sensor inputs. This self-service capability eliminates the need for complex centralized management when adding new devices, as each device automatically integrates into the network and begins operation independently.
3Reliability
If a decentralized lighting system is used, then reliability and scalability are improved, but commissioning of lighting devices becomes required
Solution Approach 1:
The commissioning process is automated through self-service mechanisms where lighting devices automatically generate and exchange necessary configuration information upon network joining. Each device independently determines its role, establishes communication parameters, and integrates into the system without manual commissioning, thereby maintaining reliability while eliminating commissioning complexity.
