Shipment-Number Access Control for Secured Parcel Delivery Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling access to secured areas for parcel delivery are inefficient and insecure, often requiring manual registration of parcel carriers, prone to errors due to facial recognition issues, and dependent on email templates that are prone to failure with changes in delivery company structures.
Innovation Solution
A system comprising an access device connected to a central server unit and database that recognizes shipment numbers and identification codes, verifying recipient registration and shipment status to grant access only when the shipment is marked 'out for delivery, eliminating the need for manual registration and reducing error-prone processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If facial recognition is used to control access for parcel carriers, then access control can be automated, but the system becomes highly prone to error due to facial expression and lighting conditions
Solution Approach 1:
The patent replaces optical/facial recognition systems with a mechanical input system (keypad or card reader) that reads shipment numbers. This substitution eliminates the reliability issues of facial recognition while maintaining automated access control through central server verification of the entered shipment number against registered recipients.
2Extent of automation
If pattern recognition databases store information for each parcel carrier, then access can be granted automatically, but the device complexity and data storage requirements increase significantly
Solution Approach 1:
The patent extracts the carrier identification element (shipment number) from the system and makes it the sole access credential. Instead of storing carrier biometric or personal data, the system only stores recipient information and authorized shipment numbers, significantly reducing database complexity while maintaining automated access control.
Solution Approach 2:
The shipment number serves multiple functions: it identifies the parcel, verifies the recipient, and acts as the access code for the secured area. This universal use of a single data element eliminates the need for separate carrier identification systems, reducing overall system complexity.
3Reliability
If manual registration of parcel carriers is required, then access security can be maintained, but the ease of operation and delivery efficiency decrease
Solution Approach 1:
The system enables self-service access where the shipment itself (through its number) serves as the key. No manual carrier registration is needed - the system automatically verifies the shipment number against the database of registered recipients and authorized deliveries, maintaining security while eliminating bureaucratic overhead.
4Adaptability or versatility
If email templates are used to retrieve shipment status, then the system can integrate with delivery companies, but the system becomes prone to error when delivery company structures change
Solution Approach 1:
The patent changes the data retrieval approach from template-based email parsing to direct database querying using stable shipment number identifiers. By using immutable shipment numbers as the interface with delivery companies and querying their databases directly, the system maintains reliable integration without being affected by changes in email structures or delivery company processes.
Data Source
AI summary
A system for controlling access to a secured area for the delivery of parcel shipments comprises an access device, a central server unit that is connected to the access device, and at least one database, which is linked with the central server unit. The access device further comprises a reading unit for recognizing a shipment number of a parcel shipment that is to be submitted and a transmitting unit for transmitting to the central server unit the recognized shipment number together with an identification number that identifies the access device. The central server unit is configured to check the shipment number and the identification number against the at least one database in order to retrieve registration information and shipment status. The central server unit is configured to transmit a release signal to the access device and the access device is configured to receive the release signal activate door opener.
