Mail Carrier Apparatus with Board and Bin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mail delivery devices do not allow easy visibility and separation of sorted mail, and they are not designed to be supported with one arm while the other hand identifies and separates mail for delivery.
Innovation Solution
A mail carrier apparatus featuring a T-shaped board with a mail bin on the back and a ledge on the front, along with a clip and pen attachment, enabling easy organization and access to mail while allowing support with the forearm, facilitating the separation and handling of mail items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional messenger-style bag is used for mail delivery, then mail can be carried and organized in compartments, but the mail carrier cannot easily see and separate sorted mail while supporting the device with one arm
Solution Approach 1:
The patent transitions from a traditional bag design to a board-based apparatus that can be supported on the forearm, creating a new dimensional configuration. The board extends horizontally in front of the carrier, allowing mail to be displayed and accessed from the side rather than requiring the carrier to dig into compartments or open flaps.
Solution Approach 2:
Instead of having mail compartments that require opening or digging into, the patent inverts the approach by having mail placed on the front face of the board where it is immediately visible and accessible. The mail bin on the back face serves as the storage compartment rather than multiple front-facing compartments.
2Ease of operation
If mail is organized in compartments within a bag, then mail can be sorted, but the carrier cannot easily identify and separate mail for delivery with the other hand
Solution Approach 1:
The board is divided into an upper portion and a lower portion, with the upper portion having a greater width than the lower portion. This segmentation allows different types of mail to be placed in different zones - larger items like magazines on the ledge and smaller envelopes in the mail bin - facilitating efficient sorting and separation.
Solution Approach 2:
The ledge acts as an intermediary surface between the mail bin and the front face of the board. Mail can be placed on the ledge for temporary holding or sorting, serving as a transition zone that facilitates the separation and handling of mail items without requiring the carrier to reach into the mail bin.
3Ease of operation
If a simple bag design is used, then the device is simple to manufacture, but it does not allow support with one arm while maintaining mail accessibility
Solution Approach 1:
The board serves multiple functions: it provides the structural support for the apparatus, displays mail on its front face, holds the mail bin on its back face, and supports the ledge for additional mail organization. This multi-functionality reduces the need for additional components while maintaining operational capabilities.
Solution Approach 2:
The patent combines the support structure, display surface, and storage integration into a single board component. The mail bin is coupled to the back face of the board, and the ledge is coupled to the front face, merging what could be separate components into an integrated assembly that simplifies manufacturing.

AI summary
A mail carrier apparatus for carrying and organizing mail for delivery includes a board having a board front face, a board back face, a board top edge, a board bottom edge, a board left edge, and a board right edge. The board has an upper portion and a lower portion. A mail bin is coupled to the board back face. The mail bin comprises a bin left side, a bin right side, a bin back side, and a bin bottom side defining a bin cavity with the upper portion of the board back face to hold mail. A ledge is coupled to the board. The ledge is coupled to the board front face proximal the board bottom edge. The ledge supports magazines and larger envelopes resting against the board.
