Workstation Visual Feedback System for Materials Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In materials handling facilities, operators face challenges in efficiently completing item-handling tasks due to the need to constantly switch between multiple information sources, such as monitors and physical documents, which diverts their attention and reduces productivity.
Innovation Solution
A visual feedback system is implemented at workstations, using imaging and depth sensors to capture data, recognize items, and project relevant visual cues directly onto the workstation surface, providing real-time feedback and instructions without requiring operators to look away from their tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operators use multiple information sources (monitors and physical documents) to complete item-handling tasks, then they can access comprehensive task information, but their attention is diverted and productivity decreases
Solution Approach 1:
The patent combines multiple information sources (monitors and physical documents) into a single projected display on the workstation surface. This merging eliminates the need for operators to switch between multiple sources, maintaining comprehensive task information accessibility while improving productivity by reducing attention diversion.
Solution Approach 2:
The patent transitions information display from vertical dimensions (monitors above, documents on desks) to a horizontal surface dimension (projection on workstation). This dimensional change allows operators to view all task information within their natural field of view, eliminating the need to look up or down, thereby maintaining information accessibility while improving productivity.
2Loss of information
If operators constantly switch between multiple information sources, then they can access comprehensive task information, but task completion speed decreases
Solution Approach 1:
The system pre-projects all necessary task information onto the workstation surface before the operator needs it. This preliminary action ensures comprehensive task information is immediately available in the operator's field of view, eliminating the time lost in switching between sources while maintaining information completeness.
Solution Approach 2:
The projected display provides continuous visual feedback and task information without interruption. Operators can maintain continuous workflow without breaking attention to switch between monitors and documents, ensuring both complete information access and reduced task completion time.
3Productivity
If visual cues are projected onto the workstation surface, then operator efficiency improves, but the system complexity increases
Solution Approach 1:
The projection system serves multiple functions: displaying task information, providing visual cues, and offering feedback mechanisms. This multi-functionality improves operator efficiency while justifying the added system complexity through consolidated utility, reducing the need for separate devices for each function.
Data Source
AI summary
Visual task feedback for workstations in a materials handling facility may be implemented. Image data of a workstation surface may be obtained from image sensors. The image data may be evaluated with regard to the performance of an item-handling task at the workstation. The evaluation of the image data may identify items located on the workstation surface, determine a current state of the item-handling task, or recognize an agent gesture at the workstation. Based, at least in part on the evaluation, one or more visual task cues may be selected to project onto the workstation surface. The projection of the selected visual task cues onto the workstation surface may then be directed.
