Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional emergency lighting devices are used with backup power supply, then the device can illuminate during power outage, but the device lacks integrated capabilities for motion detection and life localization
Solution Approach 1:
The patent combines multiple emergency response functions (lighting, motion detection via camera, life localization via CSI and AOA) into an integrated lighting apparatus. The control circuit coordinates these diverse functions to work together as a unified emergency response system, resolving the contradiction by merging previously separate capabilities into a single device.
Solution Approach 2:
The lighting apparatus is designed to perform multiple functions: providing emergency illumination, detecting motion through camera circuits, and localizing trapped individuals using CSI and AOA methods. This multi-functional design directly addresses the versatility improvement while managing device complexity through integrated architecture.
2Reliability
If lighting apparatus performs comprehensive emergency procedures including motion detection and life detection, then the emergency response capability is improved, but the device complexity increases
Solution Approach 1:
The lighting apparatus is divided into distinct functional modules: lighting unit for illumination, camera circuit for motion detection, communication circuit for CSI-based life detection, and control circuit for coordinating all functions. This segmentation allows each component to be optimized independently while maintaining overall system reliability.
Solution Approach 2:
The control circuit acts as an intermediary that coordinates between the lighting unit, camera circuit, and communication circuit. It manages the complex interactions between these components, enabling comprehensive emergency procedures while abstracting the complexity from the overall system operation.
3Measurement precision
If the lighting apparatus uses camera circuit and communication circuit for life detection, then the measurement precision for locating trapped individuals is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical search and localization methods with electronic and optical systems. The camera circuit uses optical fields for motion detection, while the communication circuit employs electromagnetic fields for CSI-based life detection and AOA positioning, achieving high measurement precision without mechanical complexity.
Solution Approach 2:
The communication circuit measures changes in channel state information (CSI) parameters to detect life presence and determine position. By monitoring parameter variations in wireless signals caused by human presence, the system achieves precise life localization through non-mechanical means.
Data Source
AI summary
A lighting apparatus, a method and a system for processing an emergency procedure are provided. The system includes two or more lighting apparatuses that are interconnected for forming a mesh network over an area. In the method, the lighting apparatus is activated to illuminate a surveillance zone under an emergency mode. In the meantime, a camera circuit is driven to capture a series of images of the surveillance zone for conduct motion detection. When a moving object is detected, the lighting apparatus transmits a beacon signal in response to the detection result. In the meantime, an acknowledgement signal in response to the beacon signal is generated by a signal source and received by the lighting apparatus. After that, the identifier with respect to the lighting apparatus is transmitted to a control center for obtaining the position of the lighting apparatus.
