Assistance system for the delivery of mail consignments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large buildings with multiple tenants, mail delivery is time-consuming due to the need for delivery personnel to carry keys for numerous buildings and deposit mail items into individual mailboxes, which can be inefficient and labor-intensive.
Innovation Solution
A mail delivery assistance system that includes a mailbox with an electronic locking mechanism and a data processing system connected to a reader that records mail item data, allowing only registered addressees to have their mail deposited, using a digital camera for OCR to identify the addressee and a control signal to unlock the mailbox for correct delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a centralized mailbox system is used for all tenants, then the number of mailboxes is reduced and delivery time is decreased, but the security and reliability of mail delivery deteriorates due to potential incorrect delivery
Solution Approach 1:
The system uses a reader to scan the mailbox number on the mail item and automatically verifies it against the registered addressee information in the database. This feedback mechanism ensures that only mail items with matching mailbox numbers can be deposited, preventing incorrect delivery while maintaining a centralized mailbox system that reduces delivery time.
Solution Approach 2:
The patent replaces the manual mechanical process of delivery personnel physically checking each individual mailbox with an automated electronic system. The reader optically scans the mailbox number, the data processing means electronically verifies it against the database, and the electronic locking mechanism automatically controls access. This substitution of mechanical verification with automated optical and electronic systems maintains delivery accuracy while enabling a centralized mailbox approach that saves time.
2Ease of operation
If delivery personnel carry keys for multiple buildings, then access to individual mailboxes is ensured, but the complexity of the delivery process increases and time is lost
Solution Approach 1:
The system uses a single centralized mailbox that serves all tenants of a building, replacing the need for multiple individual mailboxes. The electronic locking mechanism provides universal access control, allowing delivery personnel to access the centralized mailbox without carrying multiple keys for different individual mailboxes or buildings, thereby simplifying the delivery process and saving time.
3Device complexity
If a centralized mailbox is used, then the number of mailboxes is reduced and device complexity is decreased, but the risk of incorrect delivery increases
Solution Approach 1:
The system incorporates a feedback loop where the reader scans the mailbox number on the mail item, the data processing means compares it with the registered addressee information in the database, and the electronic locking mechanism responds by either allowing or preventing access. This automated feedback mechanism ensures that even with a simplified centralized mailbox system, mail delivery accuracy is maintained through automatic verification.
Solution Approach 2:
The patent introduces an intermediary automated verification system between the mail item and the centralized mailbox. The reader and data processing means act as intermediaries that verify the mailbox number against the database before allowing deposit. This intermediary layer provides the necessary reliability check without requiring complex individual mailbox systems, thus maintaining both simplicity and accuracy.
Data Source
AI summary
A mail delivery assistance system comprises a letterbox for receiving mail consignments that has an opening and an electronic locking mechanism, a data processing device that comprises a database having an address file in which a respective addressee is associated with a building address, and a reader for capturing mail consignment data of a mail consignment. The reader, during operation, is communicatively connected to the data processing device in order to send the mail consignment data to the data processing device. The data processing device checks whether the mail consignment data match an addressee in the address file, and, if this is the case, generates a control signal for the locking mechanism in order to open the opening and to allow delivery of the mail consignment.
