Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal monitoring devices face issues with signal interference, battery life, cost, and lack of tamperproof circuitry, allowing for potential tampering or removal without detection.
Innovation Solution
A monitoring device with tamper detection mechanisms, including motion and physiological sensors, tamper-avoidance wires, and BLE-based beacons, that halt signal transmission and store an indication upon removal or tampering, preventing reactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the monitoring device continues to transmit signals after removal, then the device remains operational and can be reactivated, but this allows unauthorized tampering and removal without detection
Solution Approach 1:
The system performs preliminary detection of removal conditions (motion sensor data, physiological sensor data, component presence) before halting signal transmission. This preliminary action allows the system to detect tampering and prevent reactivation before it occurs, resolving the contradiction by maintaining integrity while controlling reactivation.
Solution Approach 2:
The system uses feedback from motion sensors, physiological sensors, and component detection to continuously monitor the operational state. When removal is detected, the system provides feedback by halting signal transmission and storing an indication, thereby preventing unauthorized reactivation while maintaining system integrity.
2Reliability
If the monitoring device halts signal transmission upon detection of tampering, then unauthorized removal is prevented, but the device cannot be reactivated even for legitimate purposes
Solution Approach 1:
The system performs preliminary detection and classification of removal events before halting transmission. By storing an indication of removal in memory, the system creates a permanent record that prevents reactivation, thereby maintaining reliability while providing a clear distinction between legitimate and unauthorized removal through the stored indication.
Solution Approach 2:
The system uses an intermediary mechanism (stored indication in memory) to mediate between the detection of removal and the halting of signal transmission. This intermediary allows the system to maintain reliability by preventing reactivation while providing a clear, persistent record of the removal event that distinguishes authorized from unauthorized tampering.
3Measurement precision
If the monitoring device uses motion and physiological sensors for tamper detection, then detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system uses multi-functional sensors (motion sensors and physiological sensors) that serve both monitoring purposes and tamper detection purposes. This universal use of sensors improves measurement precision for tamper detection while minimizing the increase in device complexity by repurposing existing sensor capabilities rather than adding dedicated tamper detection hardware.

AI summary
Disclosed herein are a system, method, and computer program product embodiments for determining that a monitoring device has been tampered with or removed from a limb of a wearer of the monitoring device. For example, a determination may be made that the monitoring device has been tampered with or removed from a limb of a wearer of the monitoring device. In response to detecting that the monitoring device has been tampered with or removed from the limb of the wearer of the monitoring device, transmission of a signal from a beacon of the monitoring device may be halted, an indication indicating that the monitoring device has been tampered with or removed from the limb of the wearer of the monitoring device may be stored in a memory of the monitoring device, and re-transmission of the signal may be prevented while the indication is stored in the memory.
