Shared Vehicle Door Lock Authentication Through Window Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared vehicle systems, leaving the key or key fob inside the vehicle poses a security risk as it allows unauthorized users to access and potentially drive the vehicle, as doors are often left unlocked for convenience.
Innovation Solution
A lock control system that uses a wireless transceiver to receive a unique identifier from a remote server, an input device to capture the same identifier through a vehicle's glass component, and a lock control module to unlock the door only if the identifiers match and the time is within the designated rental period, ensuring secure access for the authorized user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If doors are left unlocked for convenience, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The system performs preliminary authentication by capturing the unique identifier from the renter's electronic device through the glass component before actuating the door lock. This advance verification ensures that only authorized renters can access the vehicle, resolving the security concern while maintaining convenience through automated validation.
Solution Approach 2:
The glass component serves as an intermediary that allows the input device to capture the unique identifier from the renter's electronic device without physical contact. This intermediary mechanism enables contactless authentication, maintaining ease of operation while ensuring security through verified identification.
2Ease of operation
If key or key fob is left inside the vehicle, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The system performs preliminary authentication by verifying the unique identifier from the renter's electronic device against the captured identifier through glass before unlocking the door. This advance verification ensures that even though the key or key fob remains inside the vehicle, only the authorized renter can access it, eliminating the security risk of unauthorized access.
3Reliability
If automatic door lock is used, then reliability is improved, but device complexity increases
Solution Approach 1:
The automatic door lock system performs self-service by automatically comparing the captured unique identifier with the stored identifier and actuating the lock without requiring manual intervention. The system autonomously determines whether to unlock the door based on the authentication result, maintaining high reliability while minimizing the need for complex manual control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows the key or key fob to be safely left inside the vehicle while ensuring only the renter can enter and use the vehicle, enhancing security by preventing unauthorized access.
Implementation Method 1
a wireless transceiver configured to wirelessly receive a first unique identifier for a period of use of the vehicle by a non-owner of the vehicle from a server that is remote from the vehicle
Implementation Method 2
an input device configured to capture a second unique identifier output by an electronic device through a glass component of the vehicle

AI summary
A lock control system includes: an automatic door lock configured to unlock and lock a door of a vehicle; a wireless transceiver configured to wirelessly receive a first unique identifier for a period of use of the vehicle by a non-owner of the vehicle from a server that is remote from the vehicle; an input device configured to capture a second unique identifier output by an electronic device through a glass component of the vehicle; and a lock control module configured to: compare the first unique identifier with the second unique identifier; and selectively actuate the automatic door lock thereby unlocking the door in response to a determination that the second unique identifier is the same as the first unique identifier.
