Parked Vehicle Damage Tracking via Mobile Device Triangulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for detecting accidental damage to parked vehicles cannot accurately identify the originator of the damage, often misclassifying individuals and failing to capture relevant evidence due to time delays and large-scale recordings, which are also privacy and legally problematic.
Innovation Solution
The method involves using at least two communication modules in a parked vehicle to triangulate the positions of mobile communication devices, capture their MAC addresses, and track their trajectories to determine the originator's device, then using a camera to record the originator's image or video, ensuring targeted and legally compliant evidence capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If environmental camera is activated with time delay to capture damage event, then damage detection is achieved, but originator identification becomes inaccurate or impossible
Solution Approach 1:
The system performs preliminary tracking of mobile communication devices and captures their positions and trajectories before the damage event occurs. By continuously monitoring and recording the positions of mobile devices in the environment prior to damage, the system ensures that the originator is already identified and captured in the records when the damage event triggers, eliminating the need for time-delayed camera activation and ensuring accurate originator identification.
2Measurement precision
If permanent large-scale observation of vehicle environment is implemented, then originator identification accuracy improves, but data protection requirements are violated
Solution Approach 1:
The system applies local quality by selectively processing and storing data only in the immediate vicinity of the damage event. Instead of permanent large-scale observation, the system activates tracking and data capture locally around the vehicle when damage is detected, capturing only the relevant mobile devices in the proximity of the damage site. This localized approach ensures data protection compliance while maintaining sufficient accuracy for originator identification.
Solution Approach 2:
The system extracts only the necessary information (positions and trajectories of mobile communication devices) from the environment around the vehicle, rather than performing permanent large-scale observation of all surroundings. By selectively capturing and processing only the relevant data elements needed for originator identification, the system achieves accurate identification without violating data protection requirements through excessive monitoring.
3Area of stationary object
If large-scale dashcam recordings are used to identify originator, then comprehensive coverage is achieved, but privacy concerns and legal compliance issues arise
Solution Approach 1:
The system transitions from large-scale dashcam recordings to localized mobile device tracking by capturing the positions and trajectories of mobile communication devices in the immediate vicinity of the damage event. This localized approach focuses data collection only on the relevant area where the originator is likely to be present, reducing the recording coverage area to the minimum necessary while eliminating privacy violations associated with broad surveillance.
