RFID Key Tracking Portal for Rental Car Return Facilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rental car companies face inefficiencies and costs due to customers often forgetting rental car keys, leading to blocked return facilities and increased staff time, as current RFID tracking systems are complex, expensive, and require individual programming and maintenance.
Innovation Solution
Implementing a system with RFID tags having a common identifier attached to rental car keys and detection portals on shuttle buses that alert staff when a key is detected, allowing for a simple and cost-effective method to prevent keys from being removed from the facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current RFID tracking systems are used to track individual keys, then key tracking capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent combines multiple RFID tags with common identifiers into a single key cluster, eliminating the need for individual tracking of each key. The detection portal detects the presence of any tagged key collectively, merging the tracking function from individual key level to cluster level, thereby reducing system complexity while maintaining reliable key tracking capability.
Solution Approach 2:
The RFID tags are designed with universal common identifiers that can be used across multiple keys simultaneously. The detection portal is configured to detect any tag with the common identifier, making the system universally applicable to all keys in the cluster without requiring individual programming or configuration for each key.
2Measurement precision
If individual RFID tags are programmed and tracked, then key identification accuracy is improved, but maintenance difficulty and cost increase
Solution Approach 1:
The patent uses inexpensive RFID tags with common identifiers that can be easily replaced if needed. Instead of investing in complex individualized tracking systems that are difficult to maintain, the solution employs simple, low-cost tags that maintain sufficient identification accuracy for the purpose of detecting key presence or absence without requiring sophisticated maintenance procedures.
3Reliability
If staff manually search for lost keys, then key retrieval is possible, but staff time and operational efficiency worsen
Solution Approach 1:
The detection portal provides immediate feedback when a tagged key is detected on the shuttle bus, alerting staff to the location of forgotten keys. This automated feedback mechanism eliminates the need for manual searching and allows staff to efficiently retrieve keys based on real-time detection information, maintaining reliable key retrieval while significantly improving operational efficiency.

AI summary
Methods and apparatus for detecting the retention of a car key by a customer after return of a rental car are disclosed. A plurality of RFID tags having a common identifier are attached to the rental car keys. The shuttle bus or other facility exit is equipped with a detection portal configured to detect a RFID tag having the common identifier and provide a signal upon detection of the RFID tag to a monitor that provides an alert upon receipt of the signal.
