Vehicle UWB Security Sensing for Unauthorized Lifting Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-theft systems for vehicles provide limited protection against theft of vehicle parts, such as wheels and catalytic converters, as they are not designed to detect unauthorized lifting or tampering.
Innovation Solution
A security system incorporating ultrawide band sensors mounted to the vehicle to monitor the vehicle's height and detect the presence of an authorization device, allowing authorized access and preventing theft by detecting unauthorized lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current anti-theft systems are used, then vehicle access control is provided, but protection against theft of vehicle parts is limited or nonexistent
Solution Approach 1:
The ultrawide band sensor performs multiple functions: it detects the presence of authorization devices for access control and simultaneously monitors vehicle height to detect unauthorized lifting attempts. This multi-functionality resolves the contradiction by providing part theft protection without requiring separate specialized detection systems.
Solution Approach 2:
The patent combines the access control function and the anti-theft monitoring function into a single integrated security system using the same sensor technology. The ultrawide band sensor merges both capabilities, eliminating the need for separate systems and thereby providing enhanced part theft protection while maintaining access control versatility.
2Measurement precision
If multiple sensors are used to detect unauthorized lifting, then detection accuracy improves, but system complexity increases
Solution Approach 1:
The ultrawide band sensor achieves multiple detection capabilities including presence detection and height monitoring functions in a single device, thereby maintaining measurement precision without increasing the number of sensors or system complexity.
Solution Approach 2:
The system monitors changes in the distance parameter between the sensor and the ground surface to detect unauthorized lifting. By tracking parameter changes over time rather than using multiple simultaneous sensors, the system achieves accurate detection while keeping device complexity low.
3Reliability
If traditional anti-theft systems are used, then vehicle access is controlled, but monitoring of vehicle height changes is not provided
Solution Approach 1:
The same ultrawide band sensor that controls vehicle access through authorization device detection also monitors vehicle height changes by tracking its distance from the ground surface. This dual functionality provides reliable unauthorized lifting detection while maintaining ease of operation, as no additional sensors or complex configurations are required.
