Rotating Mailbox Tray for Weather-Protected Curbside Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mailboxes are inconvenient for both mail delivery personnel and users, especially in inclement weather, as they require manual adjustment to accommodate delivery and user access, often necessitating users to exit vehicles.
Innovation Solution
A rotating mailbox device that automatically and mechanically adjusts to face both the postman and user, featuring a dished tray affixed directly to a post, with integrated lighting, sensors for mail indication, and a platform for easy disassembly, allowing for 90-degree rotation without additional attachment devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mailbox is made stationary to maintain structural simplicity, then device complexity is reduced, but convenience for both postman and user deteriorates as it cannot rotate to accommodate different directions
Solution Approach 1:
The mailbox is transformed from a stationary structure to a dynamic one by introducing a rotation mechanism. The dished tray is affixed to the post in a rotatable manner, allowing the mailbox to change its facing direction. This enables the mailbox to adapt to different users and delivery persons while maintaining a relatively simple overall structure.
2Adaptability or versatility
If a mailbox is designed to rotate manually to accommodate delivery persons, then adaptability improves, but ease of operation deteriorates as users must exit vehicles in inclement weather
Solution Approach 1:
The mailbox incorporates an automatic rotation mechanism that operates without human intervention. The system uses a sensor to detect when mail has been delivered and automatically rotates the dished tray to face the user's vehicle. This eliminates the need for users to manually adjust the mailbox or exit their vehicles, providing service automatically while maintaining high adaptability.
3Adaptability or versatility
If a mailbox uses additional attachment devices to enable rotation, then adaptability improves, but device complexity increases
Solution Approach 1:
The rotation mechanism is integrated directly into the connection between the dished tray and the post. Rather than using separate attachment devices, the rotatable affixing method combines the mounting and rotation functions into a single integrated solution. This reduces the number of components while maintaining the desired adaptability for rotation.

AI summary
The rotating mailbox device is provided in varying degrees of complexity, with each embodiment thereof focused on as basic a design as is possible while still retaining the important features of the device. Even the most basic design provides illuminated address, illumination strips within the mailbox assembly, and exterior indicators for indicating mail received via sensing of door opening. Of importance is that the basic design of the device dictates that the dished tray is rotateably affixed directly atop the post and may also be affixed off-center regarding the tray. The direct post-to-tray attachment negates the need for further attachment devices such as horizontal arms, for example. Lateral attachment of the mailbox assembly to the platform elevated section provides for easiest disassembly of part of the device and also for the elevated section to be a floor for the mailbox assembly.
