Pickproof Device for Rental Vehicles Using Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles for public rental, such as shared bicycles and motorcycles, face issues with damage and theft due to vandalism, where perpetrators destroy identity marks and locks, making it difficult to prevent unauthorized use and theft.
Innovation Solution
A pickproof device is integrated into the vehicle body, comprising detectors and a controller that detect abnormal external forces and movements, generating alarms and sending alerts to management and user terminals to prevent damage and theft. The device includes pressure and sound detectors to identify abnormal forces, height and friction sensors to monitor wheel movements, and a communication system to notify nearby users and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locks and identity marks are used on rental vehicles, then the vehicle structure remains simple, but the vehicles are vulnerable to vandalism and theft with no effective detection or prevention mechanism
Solution Approach 1:
The system performs preliminary detection of abnormal forces and movements before theft or damage can occur. Sensors continuously monitor the vehicle state and trigger alarms in advance when suspicious activities are detected, preventing theft rather than responding after the fact.
Solution Approach 2:
The patent introduces sensors as intermediary devices between the vehicle and the control system. These sensors detect physical forces and movements, converting them into electrical signals that the controller can process, creating a mediation layer that enables intelligent monitoring without requiring complex direct control mechanisms.
2Reliability
If multiple sensors and detection devices are added to detect abnormal forces and movements, then the anti-theft capability is improved, but the device complexity and cost increase
Solution Approach 1:
The control device performs multiple functions: it receives signals from various sensors, processes different types of detection data, determines abnormal states, triggers alarms, and communicates with external systems. This multi-functionality consolidates what could be multiple separate devices into a single integrated control unit, reducing overall system complexity.
Solution Approach 2:
The patent combines pressure sensors, sound sensors, and other detection devices into a unified monitoring system that feeds into a single control device. By merging multiple detection functions into one integrated system rather than using separate independent devices, the overall complexity is managed more effectively.
3Loss of time
If real-time monitoring and alarm systems are implemented, then the response time to theft attempts is reduced, but the energy consumption increases
Solution Approach 1:
The system uses periodic sampling of sensor data rather than continuous monitoring. The control device checks sensor signals at regular intervals to determine if abnormal states exist, maintaining effective monitoring while reducing power consumption compared to truly continuous real-time analysis.
Solution Approach 2:
The system is designed to be passive in normal operation, consuming minimal energy. It only activates alarm functions and increases power consumption when actually needed - that is, when abnormal forces or movements are detected. The system serves itself by only using energy when the situation requires it.
