Vehicle Inventory Interface Using Passive Entry RFID Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient and cost-effective method for tracking items within vehicles, leading to potential losses and inefficiencies in inventory management across multiple vehicles.
Innovation Solution
A vehicle inventory system utilizing passive entry systems with radio frequency identification (RFID) technology, where low-frequency challenges from vehicle antennas trigger high-frequency responses from tagged items, allowing for real-time tracking and inventory management through a user interface, and the integration of rules for specific routes and locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tracking technology is implemented in vehicles, then item tracking accuracy and inventory management efficiency are improved, but system cost and device complexity increase
Solution Approach 1:
The patent applies multi-functionality by enabling the existing passive entry system to serve dual purposes: traditional keyless entry and item tracking. The same antennas, controller, and key fobs used for entry authentication are repurposed to detect RFID tags and perform inventory checks, eliminating the need for separate dedicated tracking hardware and reducing overall system complexity while maintaining high tracking accuracy
Solution Approach 2:
The system implements self-service by automatically detecting items in vehicles without requiring manual intervention. The passive entry system continuously monitors for RFID tag responses, and the controller automatically compares detected items against predefined checklists and generates alerts when items are missing or unexpected, enabling autonomous inventory management
2Reliability
If comprehensive inventory tracking across multiple vehicles is implemented, then loss prevention and accountability are improved, but cost and time consumption increase
Solution Approach 1:
The system enables continuous inventory monitoring by having the passive entry system continuously scan for RFID tags whenever a vehicle is accessed or parked. The controller continuously compares detected items against the checklists stored in memory, providing real-time awareness of inventory status without requiring periodic manual checks, thus preventing losses while minimizing time investment
Solution Approach 2:
The system implements feedback mechanisms by automatically generating and displaying alerts when items are missing or when unexpected items are detected. The interface provides immediate feedback to users through visual indicators on the display screen, and the system can send notifications to mobile devices, enabling rapid response to inventory issues across the fleet without time-consuming manual audits

AI summary
A vehicle inventory interface system may include a user interface configured to present a plurality of vehicle icons each representing a vehicle in a fleet, present at least one list icon associated with each vehicle icon, receive a selection of one of the list icons, and display, in response to the selection, an inventory list associated with the selected list icon and indicating whether items specified by the inventory list are present within the vehicle.
