Foldable Container Door Indicator for Automated Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fulfillment centers face challenges in efficiently processing and transporting large volumes of packages due to complexities in order fulfillment, including delays caused by products not being in the same location and bottlenecks in directing picked products to packing stations.
Innovation Solution
The implementation of foldable containers with mechanical secured door indicators, which can be used across multiple facilities and workstations, helps improve efficiency by ensuring that containers are only transported when doors are secured, preventing movement by autonomous robots until doors are closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If foldable containers are used to transport packages, then productivity and throughput are improved, but the risk of doors being unsecured during transport increases, causing jams and safety issues
Solution Approach 1:
The container door system incorporates a self-latching mechanism that automatically secures the door when closed. The door includes a latch member that engages with a strike plate, and a spring member that biases the latch into the engaged position, eliminating the need for manual securing operations and ensuring consistent door security during transport
Solution Approach 2:
The patent replaces manual door securing operations with an automated mechanical latching system. The indicator mechanism uses optical detection (camera and machine-readable code) to monitor door status, substituting human inspection with automated sensing to prevent transport of containers with unsecured doors
2Reliability
If manual door securing is required, then door security is maintained, but processing time increases and ergonomics are worsened
Solution Approach 1:
The self-latching mechanism automatically secures the door upon closure, eliminating manual intervention. The spring-biased latch engages automatically, and the indicator system autonomously monitors and communicates door status, removing time-consuming manual checking and securing steps from the workflow
Solution Approach 2:
The indicator mechanism serves as an intermediary between the door latching system and the autonomous robot. It provides real-time status information through machine-readable codes, enabling the robot to make informed decisions about container transport without requiring manual verification of door security
3Productivity
If autonomous robots transport containers, then productivity increases, but the ability to detect door security status becomes critical
Solution Approach 1:
The indicator mechanism uses machine-readable codes (such as barcodes or color-coded indicators) that change or become visible based on door status. When the door is securely latched, the indicator displays a specific pattern or color that the autonomous robot's camera can detect, providing clear visual feedback about door security status
Solution Approach 2:
The patent replaces manual visual inspection of door status with automated optical detection. The camera-based system reads machine-readable codes or detects indicator patterns, substituting human sensory capabilities with machine vision to reliably determine door security status for autonomous decision-making

AI summary
Systems and methods are disclosed for containers having mechanical secured door indicators. In one embodiment, an example container may include a first container wall, a second container wall, a third container wall, and a fourth container wall configured to move from an open position to a closed positon. The fourth container wall may include a first portion coupled to the second container wall, and a second portion coupled to the third container wall, where the first portion and the second portion are coplanar when the fourth container wall is in the closed position. The foldable container may include a bottom container platform having a machine-readable code, and a pivotable arm configured to cover the machine-readable code when the fourth container wall is in the closed position, and to uncover the machine-readable code when the fourth container wall is not in the closed position.
