Smart Mailbox Remote Access Control Using Random Alphanumeric Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic mailboxes lack the capability to securely receive mail and goods in the absence of the intended recipient, especially with the rise of e-commerce, leading to undelivered goods and inefficiencies in delivery processes.
Innovation Solution
An interactive electronic apparatus, or 'Smart Mailbox,' that uses a user interface device, network interface, and electronic control unit to facilitate secure delivery and retrieval of mail and goods through remote communication and video calls, allowing carriers to deposit goods without contact and enabling delivery services even when the recipient is not present, utilizing a random alphanumeric code for access and cloud server management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keyless electronic mailboxes are used, then access security is improved, but the capability to securely receive goods in the absence of the recipient deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of a remote device and cloud server that mediates between the carrier and the mailbox. The remote device receives video streams from the mailbox camera and relays communication between the recipient and carrier, enabling secure delivery without direct contact or physical presence of the recipient.
Solution Approach 2:
The mailbox system performs self-service by autonomously capturing video footage, transmitting it to remote devices, and managing the delivery process without requiring the recipient's physical presence. The system automatically handles authentication, video streaming, and delivery confirmation, allowing secure goods reception in the recipient's absence.
2Ease of operation
If contactless delivery is implemented, then social distancing is facilitated, but the complexity of the delivery system increases
Solution Approach 1:
The mailbox is designed with multi-functionality, serving both as a traditional mail receptacle and as a video communication station. The same device captures video, transmits data, authenticates users, and manages delivery, eliminating the need for separate contactless delivery equipment and reducing overall system complexity.
Solution Approach 2:
The patent replaces mechanical interaction (physical handover of goods) with electronic and optical systems (video streaming and remote communication). The mailbox uses cameras, microphones, and network interfaces to substitute the mechanical contact between carrier and recipient, enabling contactless delivery while managing complexity through integrated electronics.
3Adaptability or versatility
If video call functionality is added to the mailbox, then remote communication capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the video call functionality directly into the mailbox device by integrating a camera, microphone, and network interface. This consolidation allows the mailbox to perform both its traditional function of receiving mail and the new function of video communication, reducing the need for separate devices and offsetting the added complexity through functional integration.

AI summary
A method of operating an apparatus for receiving one or more mail items is described. The method includes activating the communication between a user interface device and a remote device; generating, by an electronic control unit, at least one random alphanumeric code; sending, via a network interface device, the random alphanumeric code to the remote device; sending, by the remote device and via the network interface device, an unlock signal based on the random alphanumeric code to the electronic control unit. An unlock signal is processed by the electronic control unit to unlock the movable closure element and allow one or more mail items to be introduced in or withdrawn from the internal cavity.
