Movable Belt Ceiling Secure Tote for Order Fulfillment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional order fulfillment systems face issues with the constant open state of shipment containers, leading to inadvertent placement of incorrect items and unauthorized removal of items during the fulfillment process, particularly problematic in systems handling drugs or medications.
Innovation Solution
A secure tote with a movable belt that forms a closed ceiling and floor, using a belt drive to control the aperture's position, ensuring secure access only at designated stations for item placement and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shipment container remains open during the fulfillment process, then employees can easily access and place items, but this leads to inadvertent placement of incorrect items and unauthorized removal of items
Solution Approach 1:
The patent applies the dynamics principle by making the container ceiling movable rather than fixed. The belt-based ceiling can transition between open and closed states, allowing the system to adapt its configuration based on the operational phase. During item placement, the ceiling is open for easy access; during transport and verification, the ceiling closes to secure the contents. This dynamic transformation resolves the contradiction between ease of access and fulfillment accuracy.
2Productivity
If the shipment container is kept open for easy item access, then fulfillment speed increases, but security against unauthorized access decreases
Solution Approach 1:
The movable ceiling belt enables the container to dynamically switch between open and closed configurations. During active fulfillment operations, the ceiling remains open to maintain high productivity and easy item access. Once fulfillment is complete or during transport between stations, the ceiling automatically closes to prevent unauthorized access. This temporal separation of open and closed states allows the system to achieve both high productivity and security.
3Reliability
If a secure closed container is used, then item security is improved, but ease of item placement and removal is reduced
Solution Approach 1:
The patent applies segmentation by dividing the container ceiling into a movable belt component that can be independently controlled. Rather than requiring the entire container to be opened for item access, only the ceiling section is segmented and made movable. This allows the bulk of the container to remain closed and secure while a specific segment (the ceiling belt) opens to provide controlled access during fulfillment operations, then closes to restore security.

AI summary
One aspect of this disclosure provides a tote that has first and second sidewalls that define the tote's length and height and are laterally offset by the tote's width. Third and fourth substantially planar sidewalls are coupled to the first and second sidewalls to form a frame. A plurality of parallel belt guides are located within an interior space of the tote and is coupled to the frame. A belt that has at least half the tote's width is supported by the plurality of the belt guides and defines at least a portion of a ceiling of the tote. The belt is movable about the interior space of the tote, such that the aperture can be positioned within the tote in one of a plurality of positions.
