Solution Overview
Problem
In monitoring systems with sensors embedded in lighting equipment, users may inadvertently turn off the power supply, leading to erroneous operation and prolonged sensor downtime, affecting the system's functionality.
Innovation Solution
A monitoring system that includes lighting equipment powered by main power, a remote control device, a battery for reserve power, a detector to sense power stoppage, and a communicator to transmit detection results using reserve power, along with a selector to switch between main and reserve power, and a controller to manage power consumption and sensor operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the sensor is mounted on the lighting equipment to reduce user awareness and stress, then the resident's comfort is improved, but the sensor stops operation when the lighting equipment is turned off by the user
Solution Approach 1:
The system performs preliminary action by detecting power stoppage before the sensor fully stops operation, and activates the battery-powered transmission mode in advance to ensure continuous monitoring capability. The detector identifies when main power is stopped, and the system proactively switches to reserve power mode rather than waiting for sensor failure.
Solution Approach 2:
The system changes the power supply parameter from main power to battery power when power stoppage is detected. This parameter change allows the sensor and communicator to continue operation under different power conditions, maintaining monitoring functionality regardless of the lighting equipment's power state.
2Ease of operation
If the user turns off the wall switch to turn off the lighting equipment, then the lighting control is simplified, but the sensor mounted on the equipment is stopped accordingly
Solution Approach 1:
The detector performs preliminary detection of power stoppage caused by wall switch operation, and the system proactively activates battery-powered communication mode before the sensor completely stops. This ensures that even brief or erroneous power cutoffs are detected and reported, maintaining monitoring reliability.
Solution Approach 2:
The system establishes feedback by having the communicator transmit detection results to external devices or other system components. This feedback loop allows the monitoring system to remain aware of and respond to power stoppage events, enabling corrective actions or alerts to be generated based on the detected conditions.
3Reliability
If the user presses the lighting-off button of the remote control device to turn off the lighting equipment with the sensor in operation, then the sensor continues to operate, but the operation steps are increased
Solution Approach 1:
The system performs self-service by automatically detecting power stoppage and switching to battery-powered transmission mode without requiring user intervention. The detector and communicator work autonomously to maintain monitoring functionality, eliminating the need for users to take special actions to preserve sensor operation.
Solution Approach 2:
The communicator provides feedback by transmitting detection results about power stoppage events to external systems. This automatic feedback mechanism ensures that the monitoring system remains informed about operational status changes without requiring user reporting or manual intervention.
4Loss of energy
If the sensor is stopped for a long period of time due to erroneous wall switch operation, then power consumption is reduced, but the monitoring system operation is affected
Solution Approach 1:
The detector performs preliminary detection of power stoppage events, and the system proactively activates battery-powered communication before the sensor fully stops. This preliminary action prevents complete sensor shutdown and ensures continuous monitoring capability, addressing the reliability issue while managing power consumption through selective activation.
Solution Approach 2:
The system changes the power supply parameter from main power to battery power, enabling continued operation under different power conditions. This parameter change allows the system to maintain monitoring functionality with reduced power consumption from the main power supply while using the battery to sustain critical operations.

AI summary
An object is to reduce influence of erroneous operation in a monitoring system provided with a sensor.Lighting equipment is to be turned on by means of main power. A remote control device turns off the lighting equipment. A battery supplies reserve power. A sensor performs predetermined measurement by means of the main power. A detector detects whether or not supply of the main power has been stopped by operation of a predetermined switch, and generates a detection result. A communicator transmits the detection result by means of the reserve power in a case where the supply of the main power has been stopped.
