Automated Sweeper for Item Sortation Floor Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fulfillment centers face inefficiencies in processing high volumes of orders due to issues like lightweight items falling during transport in item sortation systems, causing delays and requiring manual retrieval, which disrupts the operation and increases labor costs.
Innovation Solution
Automated sweepers are deployed within the item sortation systems to collect fallen items from the floor and re-induct them into the system, allowing for continuous operation without manual intervention, improving throughput and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual retrieval of fallen items is implemented, then item recovery is achieved, but operation disruption and labor costs increase
Solution Approach 1:
The system uses automated sweepers that autonomously navigate the sortation floor, detect fallen items using sensors, and retrieve them without human intervention. The sweeper independently performs the complete retrieval cycle, making the system self-serving and eliminating the need for manual labor while maintaining continuous operation
Solution Approach 2:
Manual mechanical retrieval by workers is replaced with an automated robotic sweeper system equipped with sensors, navigation capabilities, and item collection mechanisms. This substitution transforms a labor-intensive process into an automated mechanical system that operates continuously without disrupting sortation flow
2Productivity
If high-speed sortation is implemented, then throughput increases, but item stability during transport deteriorates
Solution Approach 1:
The automated sweeper operates continuously alongside the high-speed sortation process, maintaining constant surveillance and retrieval capability. This ensures that even at high throughput speeds, any items that fall are immediately recovered, maintaining system reliability without requiring reduction of sortation speed
Solution Approach 2:
The automated sweeper acts as an intermediary between the high-speed sortation system and the floor surface, serving as a buffer that captures fallen items before they cause disruptions. This intermediary system allows the main sortation process to operate at high speed while the sweeper handles the consequences of item instability
3Productivity
If automated sweepers are deployed, then operation continuity is maintained, but device complexity increases
Solution Approach 1:
The automated sweeper is designed as a multi-functional unit that combines navigation, item detection using sensors, item retrieval, and re-induction capabilities in a single device. This universal design consolidates multiple functions into one system, managing complexity through integration rather than proliferation of separate components
Solution Approach 2:
The sweeper implements a recover-and-reuse approach where fallen items are collected, temporarily held, and then re-inducted back into the sortation system at appropriate points. This recovery mechanism maintains operation continuity by preventing item loss while managing system complexity through structured item flow control

AI summary
Systems, methods, and computer-readable media are disclosed for automated sweepers for item sortation systems. In one embodiment, an example item sortation system may include an aisle, a number of chutes accessible from the aisle, a shuttle configured to transport first items from an induction portion of the item sortation system to a first chute of the plurality of chutes, and a robotic sweeping system disposed in the aisle. The robotic sweeping system may be configured to sweep second items on a floor of the aisle to a first end of the item sortation system. The robotic sweeping system may include a motor and a sweeping device.
