Beacon-Controlled Camera Shutter for Medical Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring systems in medical and welfare facilities often compromise the privacy of patients or care recipients by constant surveillance, causing stress due to visible camera capture, and existing systems lack accurate detection of healthcare provider presence to manage image capturing effectively.
Innovation Solution
A monitoring system with a transmitter carried by the treatment provider, a monitoring device placed near the doorway, and a second beacon detector near the treatment location, using beacon signals to control an open-close mechanism for the camera, ensuring privacy protection by determining the provider's presence and adjusting image capture accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surveillance cameras continuously monitor treatment recipients, then monitoring effectiveness is improved, but privacy protection deteriorates and treatment recipients experience stress
Solution Approach 1:
The camera system dynamically adjusts its operation state based on real-time detection of treatment provider presence. The open-close body (shutter) opens when a provider is detected and closes when not detected, transforming the static continuous monitoring into dynamic conditional monitoring that balances security and privacy
Solution Approach 2:
The system uses beacon detectors to continuously detect the presence of treatment providers and feeds this information back to the control unit, which then adjusts camera operation accordingly. This feedback loop enables the system to respond automatically to changing conditions in the treatment room
2Reliability
If continuous image capturing is performed, then monitoring reliability is improved, but treatment recipient privacy is compromised
Solution Approach 1:
The system performs preliminary detection of treatment provider presence using beacon signals before activating the camera. The open-close body is controlled to open only when a provider is detected, preventing unnecessary image capture and thus protecting privacy while maintaining monitoring reliability when needed
3Measurement precision
If beacon detectors are installed near both doorway and treatment location, then provider presence detection accuracy is improved, but device complexity increases
Solution Approach 1:
The presence detection function is segmented into two independent beacon detectors positioned at different locations (near doorway and near treatment location). Each detector handles a specific detection zone, and the control unit integrates their outputs to determine overall provider presence, improving accuracy without requiring a single complex detector system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively protects the privacy of treatment recipients by accurately determining the healthcare provider's presence and controlling camera operation, allowing monitoring while minimizing stress and maintaining privacy.
Implementation Method 1
The transmitter transmits a beacon signal
Implementation Method 2
The first beacon detector detects a first received signal strength indicator of the beacon signal from the transmitter. The second beacon detector detects a second received signal strength indicator of the beacon signal from the transmitter
Data Source
AI summary
A monitoring system can protect the privacy of a treatment recipient while monitoring the treatment recipient being treated. A transmitter transmits a beacon signal. A beacon detector detects an RSSI(2) of the beacon signal. A monitoring device includes an imaging element, an open-close body, a beacon detector, an obtainer, and an open-close body controller. The imaging element captures an image of a treatment recipient being treated by a treatment provider through an opening. The open-close body opens and closes the opening. The beacon detector detects an RSSI(1) of the beacon signal. The obtainer obtains the RSSI(2) detected by the beacon detector. The open-close body controller controls opening and closing of the open-close body based on the RSSI(1) detected by the beacon detector and the RSSI(2) obtained by the obtainer.
