Parcel Box Door Lock Deactivation to Prevent Accidental Entrapment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parcel boxes installed outdoors are at risk of accidental locking, particularly due to unsupervised environments, which can lead to children or others being inadvertently trapped.
Innovation Solution
A method that uses an access control apparatus to measure time since a user event occurred and deactivates the locking mechanism if the door remains open beyond a predetermined threshold, preventing the door from being locked and ensuring it remains unlockable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking mechanism is activated to prevent misuse and theft of parcel boxes, then security and reliability are improved, but the risk of accidental locking increases, particularly endangering children or unsupervised persons
Solution Approach 1:
The system performs preliminary actions by detecting door opening events and measuring time intervals before the locking mechanism is activated. The access control apparatus monitors whether a door has been open for a predetermined time period and deactivates locking in advance if the condition is met, preventing accidental locking before it can occur.
Solution Approach 2:
The system implements feedback by continuously monitoring door state and time measurements, then using this information to control the locking mechanism. The access control apparatus receives feedback from door sensors and time measurements, processes this information, and adjusts locking status accordingly, creating a closed-loop safety system.
2Reliability
If the door is automatically locked upon closing to prevent unauthorized access, then security is improved, but the door becomes inaccessible to authorized persons who arrive later
Solution Approach 1:
The locking status of the door is made dynamic rather than static. The system continuously evaluates time measurements and door state, adjusting the locking status in real-time. The door can transition between locked and unlocked states based on whether the open duration exceeds the predetermined threshold, providing adaptive access control.
3Reliability
If the locking mechanism remains continuously active to ensure security, then protection against theft is improved, but the system complexity and energy consumption increase
Solution Approach 1:
Instead of continuous locking, the system uses periodic monitoring and time-based evaluation. The access control apparatus periodically checks door state and measures time intervals, activating or deactivating locking based on whether the predetermined time threshold is exceeded, reducing continuous system activity while maintaining protection.

AI summary
The invention relates to a method for deactivating the locking of at least one door of an accommodating device, said method comprising: effecting the unlocking of the at least one door, measuring the time since at least one event detected by an access-monitoring device of the accommodating device has occurred, and effecting, if the at least one door is open and the measured time exceeds a specified time threshold value, the deactivation of the locking of the at least one door in such a way that the at least one door cannot be locked. The invention further relates to an access-monitoring device, a computer program, an accommodating device, a system, and a use of the accommodating device.
