Vehicle Door Control Device for Secure Parcel Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The delivery of shipments to vehicles poses security concerns as existing methods lack effective mechanisms to ensure the proper course of delivery without the personal presence of the shipment recipient, leading to potential unauthorized access and incomplete or aborted delivery processes.
Innovation Solution
A control device installed in the vehicle that uses communication technology to unlock and lock the vehicle's door based on access authorization information and predefined delivery events, ensuring secure and complete delivery processes by monitoring delivery events such as door opening, shipment placement, and duration of the delivery process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is unlocked to enable delivery access, then delivery convenience is improved, but security risk increases due to potential unauthorized access
Solution Approach 1:
The control device continuously monitors delivery event information (door opening, shipment placement, process duration) and dynamically adjusts the unlocked state based on this feedback. The door remains unlocked only as long as authorized delivery activities are detected, and automatically locks when delivery is completed or aborted, eliminating continuous unauthorized access risk while maintaining delivery convenience during the process.
Solution Approach 2:
The system performs preliminary verification of access authorization information before unlocking the door. Only after confirming valid authorization does the door unlock, preventing unauthorized access from the outset. This preliminary security check ensures that convenience is provided only to authorized parties.
2Productivity
If the door remains unlocked during delivery process, then delivery efficiency is improved, but security vulnerability increases if delivery is aborted or takes too long
Solution Approach 1:
The door locking state transitions dynamically based on delivery process status. The door unlocks when authorized delivery begins and remains unlocked throughout the delivery process to maintain efficiency. However, if the delivery is completed or aborted (detected through monitoring delivery event information), the door automatically locks, thereby adapting the security state to the current delivery situation and eliminating prolonged vulnerability.
Solution Approach 2:
The control device autonomously manages the door locking state based on monitored delivery events without requiring continuous manual intervention. When delivery completion or abortion is detected, the system self-activates the locking function, ensuring security is restored automatically while maintaining delivery efficiency during the process.
3Speed
If access authorization is granted without verification, then delivery speed is improved, but security control is weakened leading to improper delivery courses
Solution Approach 1:
The control device performs preliminary verification of access authorization information before granting door access. This preliminary check confirms the deliverer's credentials and intended delivery destination, ensuring security control is maintained while enabling rapid subsequent access. The verification happens once before unlocking, not continuously during the process, thus balancing speed and security.

AI summary
The disclosure includes, among other things, a method for causing the unlocking and locking of at least one door (11) of a vehicle (10) for the delivery of a shipment, in particular a parcel and/or a letter, into the vehicle, comprising the following: - receiving (301, 401) access authorization information at a control device (100), - causing (302, 403) the unlocking of the door (11) of the vehicle (10) at least partially depending on the received access authorization information by the control device, - receiving (303, 405, 407, 408, 410) one or more delivery event information associated with a delivery event at the control device (100), - causing (304, 411) the locking of the door (11) of the vehicle (10) by the control device only if the received delivery event information corresponds to one or more predefined delivery events are associated.
