Solution Overview

Problem

In the warehousing and logistics industry, the introduction of automation technologies has led to inefficiencies in sorting and delivery processes due to increased complexity and potential delivery errors, resulting in reduced sorting efficiency as items are often misrouted, requiring secondary sorting and increasing delivery distances.

Innovation Solution

A sorting system and method that divides the sorting area into sub-areas with dedicated supply stations and delivery openings corresponding to specific destinations, where a control server assigns tasks to sorting robots to deliver items to the correct sub-area and opening based on destination information, ensuring accurate routing and reducing cross-sub-area deliveries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the sorting area is expanded to handle more items, then the sorting capacity increases, but the delivery distance increases and delivery accuracy decreases

Engineering Contradiction:
Improvesorting capacityVSAvoiddelivery accuracy
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The sorting area is divided into multiple sub-areas, each with dedicated supply stations and delivery openings. This segmentation allows items to be sorted within smaller zones, reducing delivery distances and improving delivery accuracy while maintaining overall sorting capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control server acts as an intermediary that receives item information, determines the appropriate sub-area and delivery opening, and guides items to their correct destinations. This centralized control mechanism ensures accurate routing across the expanded sorting area.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A sorting system includes a control server, multiple sorting robots, and a sorting region. The sorting region is divided into multiple sub-regions. At least one supply station and multiple delivery openings are deployed in each sub-region. Delivery openings respectively correspond to paths. The control server determines, according to path information of an item to be sorted, a target delivery opening corresponding to a path of the item, determines, from the multiple sub-regions of the sorting region, a target sub-region in which the target delivery opening is located, and allocates a delivery task to a target sorting robot among the multiple sorting robots. In response to the delivery task, the target sorting robot acquires the item from the supply station where the item is located, carries the item to the target delivery opening in the target sub-region, and delivers the same.
