Solution Overview

Problem

Existing systems for commissioning goods face challenges in efficiently managing the flow of goods between horizontal and vertical conveyor stages, particularly in maintaining order and reducing operational interdependence between conveyors.

Innovation Solution

A system comprising multiple lanes with conveyors and buffers that allow for the interleaving of goods on conveyors, enabling independent operation of horizontal conveyors and vertical buffers to maintain order and efficiency in goods transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple horizontal conveyors transport goods to vertically stacked buffers, then goods flow management is improved, but operational interdependence between conveyors increases

Engineering Contradiction:
Improvegoods flow managementVSAvoidoperational interdependence
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the goods flow into separate horizontal conveyor stages (first horizontal conveyor, second horizontal conveyor) that operate independently, with each conveyor serving specific lanes. This segmentation reduces operational interdependence while maintaining efficient goods flow management through the vertically stacked buffer architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Vertically stacked buffers act as intermediary storage elements between horizontal conveyors and the vertical conveyor. These buffers decouple the operational dependencies by allowing goods to be temporarily stored and released in a controlled manner, enabling independent conveyor operation while maintaining overall system productivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If horizontal conveyors operate independently, then operational flexibility is improved, but maintaining goods order becomes more difficult

Engineering Contradiction:
Improveoperational flexibilityVSAvoidgoods order
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

Goods are pre-positioned in vertically stacked buffers before being transferred to the vertical conveyor. This preliminary arrangement in the buffer stage allows independent conveyor operation while ensuring goods are ready in the correct sequence, maintaining order without requiring synchronized conveyor operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The vertically stacked buffers serve as an intermediary sorting and holding mechanism that receives goods from independent horizontal conveyors and releases them in the correct order to the vertical conveyor. This intermediary stage decouples the independence of conveyors from the requirement of maintaining goods order.

Inventive Principle:
Principle #24Intermediary (Mediator)
