Vehicle Key Access Management System Using Remote Static Identifier Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared or rental vehicle setups, distributing and managing physical keys can be cumbersome and inefficient, especially when multiple users need access to vehicles.
Innovation Solution
A key access management system that communicates with a remote database to read and verify static identifiers, such as NFC chips, biometric data, or other unique objects/personal characteristics, allowing secure and convenient access to vehicles without the need for multiple keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical keys are distributed to multiple users for shared or rental vehicles, then access control is achieved, but key management becomes cumbersome and inefficient
Solution Approach 1:
The system replaces multiple physical keys with a single universal remote server that manages access for all users. The remote server communicates with the vehicle's key access management system to authenticate users and grant access, eliminating the need for multiple physical keys while maintaining secure access control.
Solution Approach 2:
Instead of distributing physical copies of keys to multiple users, the system creates digital copies of access credentials stored in a database on the remote server. Each user receives a digital key representation that can be transmitted to their device, allowing multiple users to have access without requiring multiple physical key copies.
2Adaptability or versatility
If multiple physical keys are distributed for vehicle access, then multiple users can access the vehicle, but security management and key distribution become complex
Solution Approach 1:
The system extracts the key management functionality from the physical keys themselves and relocates it to a remote server. The remote server stores all access credentials and user information, communicating with the vehicle to authenticate users. This centralizes the complexity in one location rather than distributing it across multiple physical keys.
Solution Approach 2:
The remote server acts as an intermediary between users and the vehicle. Instead of users directly interacting with physical keys or the vehicle's locking mechanism, all access requests are routed through the remote server, which authenticates users and coordinates with the vehicle's key access management system to grant or deny access.
3Ease of operation
If static identifiers are stored in a remote database and communicated to the vehicle, then access management is simplified, but communication infrastructure is required
Solution Approach 1:
The system performs preliminary actions by pre-storing all user credentials and vehicle access information in a database on the remote server before access is needed. When a user attempts to access the vehicle, the remote server quickly retrieves the stored credentials and communicates them to the vehicle's key access management system, enabling fast authentication without requiring complex real-time processing.
