Loss Detection via Multi-Device Motion Data Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often falsely report loss incidents due to changing orientation criteria, leading to unnecessary notifications when no loss has occurred.
Innovation Solution
Establishing a communication link between two electronic devices to compare motion-related sensing information, determining if a loss incident has occurred by analyzing signal patterns from gyro and acceleration sensors, and issuing notifications only when discrepancies are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion detection is used to determine loss incidents, then loss detection capability is improved, but false notifications increase due to orientation changes
Solution Approach 1:
The patent combines motion detection data from multiple electronic devices (wearable device and mobile device) to determine loss incidents. By merging the sensing information from both devices, the system achieves more reliable loss detection while reducing false notifications caused by orientation changes of a single device.
Solution Approach 2:
The patent introduces a communication link as an intermediary to transmit and synchronize motion detection information between the wearable device and mobile device. This intermediary enables comparison of motion patterns from different devices, allowing the system to distinguish between intentional orientation changes and actual loss incidents.
2Device complexity
If single device motion detection is used, then device complexity is reduced, but measurement precision deteriorates due to orientation ambiguity
Solution Approach 1:
The patent merges motion detection capabilities of multiple devices to achieve higher measurement precision. By combining data from the wearable device and mobile device, the system overcomes the orientation ambiguity that would affect a single device, without adding complex hardware to either individual device.
Solution Approach 2:
The patent makes the loss detection system multi-functional by utilizing existing motion sensors in both wearable and mobile devices for their original purposes plus loss detection. This universal approach allows precise motion measurement without requiring dedicated loss detection hardware, thus avoiding increased device complexity.
