Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing intelligent lighting systems use complex network installation and configuration procedures, then lighting control functionality is achieved, but installation cost significantly increases
Solution Approach 1:
The patent extracts and removes intermediary devices from the lighting system, allowing lighting devices to communicate directly with each other through wireless communication. This eliminates the need for complex network installation and configuration procedures while maintaining lighting control functionality, thereby significantly reducing installation costs.
Solution Approach 2:
The patent introduces a simplified communication protocol that acts as an intermediary mechanism between lighting devices, enabling direct peer-to-peer communication without requiring complex network infrastructure. This intermediary protocol reduces installation complexity while preserving control capabilities.
2Loss of information
If intermediary devices are used for signal transmission in existing lighting systems, then signal transmission is achieved, but system complexity increases
Solution Approach 1:
The patent removes intermediary devices from the signal transmission path, enabling lighting devices to communicate directly through wireless communication protocols. This extraction eliminates unnecessary system components while maintaining effective signal transmission between devices.
3Area of stationary object
If a large number of lighting devices are deployed in existing systems, then coverage area increases, but network traffic becomes excessive causing system failure
Solution Approach 1:
The patent segments the lighting system into independent lighting devices that communicate directly with each other without relying on a centralized network infrastructure. Each device operates autonomously, preventing network traffic overload even when a large number of devices are deployed, thereby maintaining system stability while expanding coverage area.
4Adaptability or versatility
If lighting devices run complex protocol codes, then communication functionality is achieved, but software cost increases
Solution Approach 1:
The patent employs simplified communication protocols that can be implemented with basic software components, replacing complex protocol stacks. This approach uses simpler, more cost-effective software solutions that achieve the necessary communication functionality without requiring expensive proprietary protocols.
5Adaptability or versatility
If lighting devices run complex protocol codes, then communication functionality is achieved, but hardware cost increases
Solution Approach 1:
The patent extracts and removes the requirement for complex protocol processing hardware from lighting devices. By using simplified communication protocols, the system can operate with basic wireless communication capabilities, eliminating the need for expensive specialized hardware components while maintaining communication functionality.

AI summary
A lighting system includes multiple lighting devices (11) distributed within a preset area and communicating with each other. Each one of the lighting devices is configured to, upon detecting a moving object (HR), continuously generate a detection signal (Ds) and enter a master mode. When a first one of the lighting devices enters the master mode, the first lighting device functions as a master lighting device (LA) and remaining one or more of the lighting devices function as one or more controlled lighting devices (LB). The master lighting device is configured to emit light and broadcast a control signal (Cs), and each controlled lighting device is configured to emit light based on a signal strength of the control signal being received by the respective controlled lighting device.
