Collision-Activated RFID Recorder for Vehicle Accident Data Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an efficient method to collect and store identifying information from RFID tags of witnesses, vehicles, or surveillance equipment at the scene of accidents, hindering law enforcement investigations, especially in hit-and-run cases where perpetrators often flee without being identified.
Innovation Solution
A collision-activated RFID reader/recorder system mounted on vehicles, equipped with a transceiver, collision sensor, and antenna, which generates an electromagnetic pulse to activate RFID tags within a collision zone, collecting and storing unique identifying data from nearby RFID tags, including those on witnesses, vehicles, or surveillance equipment, and allowing secure access to authorized users via authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a collision-activated RFID reader/recorder system is implemented to collect identifying information from RFID tags at accident scenes, then the efficiency and thoroughness of law enforcement investigations is improved, but the device complexity increases due to the need for collision sensors, transceivers, electromagnetic pulse generation, and memory storage systems
Solution Approach 1:
The patent combines multiple functions into a single integrated system: the collision sensor detects accidents, the transceiver generates electromagnetic pulses to activate RFID tags, and the memory stores identifying information. This merging of detection, activation, and storage functions into one device resolves the technical contradiction by achieving investigation efficiency without requiring multiple separate systems.
Solution Approach 2:
The system performs preliminary action by automatically collecting and storing identifying information from RFID tags at the moment of collision, before the scene is disrupted or witnesses flee. This preliminary data capture resolves the contradiction by ensuring investigation efficiency is achieved through pre-collected evidence, offsetting the added system complexity.
2Reliability
If the RFID reader/recorder remains continuously active to capture identifying information, then the reliability of witness identification is improved, but the energy consumption increases significantly
Solution Approach 1:
The system uses periodic action by triggering the RFID reader/recorder only at specific moments when a collision is detected, rather than operating continuously. The collision sensor activates the transceiver to generate electromagnetic pulses only when needed, ensuring identification reliability is maintained while dramatically reducing energy consumption compared to continuous operation.
Solution Approach 2:
The system employs self-service by using the collision sensor to automatically trigger the data collection process without requiring continuous power or manual activation. The electromagnetic pulse is generated only when the collision sensor detects an accident, allowing the system to maintain identification reliability while consuming energy only when necessary for its function.
3Quantity of substance
If the electromagnetic pulse transmission range is extended to cover larger collision zones, then the quantity of RFID tags detected increases, but the power required for transmission increases
Solution Approach 1:
The system applies partial action by transmitting electromagnetic pulses only in the specific direction and zone where a collision has been detected, rather than broadcasting in all directions continuously. This allows the system to detect multiple RFID tags within the relevant collision zone while using minimal transmission power, resolving the contradiction between detection quantity and power consumption.
