Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current order picking systems are slow, labor-intensive, and costly, with operators often waiting for product containers to be delivered, leading to inefficiencies in high-volume distribution and fulfillment operations.
Innovation Solution
A goods to operator workstation with a container staging platform and holding platform that are linearly and pivotally movable, allowing for rapid delivery and discharge of product containers, enabling operators to pick products quickly and efficiently by attaching to an input and discharge conveyor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual order picking is used where operators walk through racks to pick products, then flexibility and adaptability are maintained, but productivity is low and labor costs are high
Solution Approach 1:
The system inverts the traditional picking approach by bringing products to the operator rather than having the operator walk to products. The goods-to-operator workstation delivers product containers sequentially to the operator at the picking station, reversing the motion flow and eliminating operator travel time while maintaining high productivity.
Solution Approach 2:
The system performs preliminary actions by pre-positioning product containers on the input conveyor system before they reach the operator. The robotic system retrieves products from storage and stages them in advance on the conveyor, so they are ready for immediate picking when the operator needs them, eliminating wait time and improving productivity.
2Productivity
If automated conveyor systems are introduced to deliver products to operators, then productivity increases, but device complexity increases
Solution Approach 1:
The goods-to-operator workstation serves multiple functions within a single integrated unit: it receives products from the input conveyor, stages them appropriately, presents them to the operator at the correct position, and collects picked products for discharge. This multi-functionality reduces the need for separate specialized components, managing system complexity while maintaining high productivity.
Solution Approach 2:
The system is divided into distinct functional modules: an input conveyor system for product reception, a staging area for temporary holding, a discharge conveyor for picked products, and control systems. This segmentation allows each component to be optimized independently and simplifies maintenance and operation while achieving high overall productivity.
3Ease of operation
If robotic systems are used to deliver product containers sequentially to operators, then labor requirements decrease, but the system may operate slower than the picker's capability
Solution Approach 1:
The conveyor system is designed to be dynamic and adaptive, adjusting the delivery speed of product containers to match the operator's picking speed in real-time. The system can accelerate or decelerate container delivery based on operator performance, ensuring that the robotic system operates at optimal speed without becoming a bottleneck, thereby maintaining ease of operation while maximizing delivery speed.

AI summary
A goods to operator workstation is attachable to an input and a discharge conveyor system. The goods to operator workstation comprises a container staging platform that receives a product container from the input conveyor system and linearly moves the product container to an order pick position for an operator to pick articles from. A holding platform is pivotally movable between the order pick position and a discharge position to discharge a picked order container onto the discharge conveyor system after picking. Wherein when the holding platform moves back to the order pick position, the holding platform passes through the staging platform to transfer the order container from the staging platform to the holding platform so that the staging platform can retract and receive a new order container from the input conveyor system while the operator is picking.
