Smart Mailbox Code Management for Secure Unattended Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The uncertainty in delivery times for internet shopping creates inconvenience for both senders and recipients, as they often need to coordinate for mail receipt or delivery, which can be troublesome and inconvenient, especially when security or access issues arise.
Innovation Solution
A smart mailbox system with a lock, communication unit, and processor that allows for remote management, including code input, camera monitoring, and sensor integration for secure and automated mail receipt and sending, enabling safe and convenient handling of mail without the need for immediate recipient presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mailbox delivery is used, then mail can be delivered to the recipient, but coordination is needed between sender and recipient which causes inconvenience and time loss
Solution Approach 1:
The mailbox system enables self-service delivery by automatically managing the delivery process. The recipient receives notification of delivery arrival and can retrieve mail independently through code input, eliminating the need for coordination with the sender or courier. The system performs functions autonomously including delivery notification, secure storage, and controlled access.
Solution Approach 2:
The smart mailbox acts as an intermediary between the sender/courier and the recipient. It receives mail from the sender, securely stores it, and provides controlled access to the recipient through automated code verification. This intermediary function eliminates direct coordination needs between sender and recipient while ensuring secure transfer.
2Reliability
If traditional mailbox delivery is used, then mail can be delivered, but security issues arise when couriers need to wait in the hall or recipients need to go downstairs
Solution Approach 1:
The system performs preliminary actions by delivering mail to the secure mailbox location in advance of when the recipient needs it. The mailbox is prepared and secured beforehand, and the recipient is notified of delivery arrival before actually retrieving the mail. This eliminates the need for immediate presence or waiting in hallways.
Solution Approach 2:
The smart mailbox serves as a secure intermediary that receives and holds mail safely without requiring courier or recipient presence in vulnerable locations. It provides a secure storage intermediate state between delivery and retrieval, eliminating security risks associated with hallway waiting or downstairs collection.
3Reliability
If code validation is implemented, then mailbox security is improved, but code management complexity increases
Solution Approach 1:
The code management system performs self-service by automatically generating, validating, and revoking access codes without requiring manual intervention. The processor automatically verifies input codes against stored valid codes, and the system autonomously manages the lifecycle of access credentials, reducing operational complexity despite enhanced security.

AI summary
A mailbox comprises a box body with a door having a lock, a mailbox unlocking code input device for inputting an unlocking code to unlock the mailbox, a communication module for communicating with a remote management terminal, a storage module at the mailbox or the remote management terminal for storing one or more preset mailbox unlocking codes, and a processor at the mailbox or the remote management terminal for identifying whether the input mailbox unlocking code matches the one or more preset mailbox unlocking codes, and issuing a mailbox unlocking instruction if matching. The processor comprises a mailbox unlocking code management circuit used to invalidate the matched mailbox unlocking code after the mailbox is unlocked, generate a new mailbox unlocking code when no valid mailbox unlocking code is currently available, and store the new mailbox unlocking code in the storage. The mailbox can safely, conveniently and automatically receive and/or send mail.
