Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional inventory container-to-person sorting methods require robots to move entire containers, increasing their load and resource waste, and limit the efficiency and flexibility of package picking in warehousing and logistics.

Innovation Solution

A transfer robot with a movable chassis, vertically arranged door frame, temporary storage mechanism, and cargo box conveying mechanism, allowing the cargo box conveying mechanism to rotate, rise, and fall vertically, independent of the temporary storage mechanism, facilitating efficient transfer and picking of cargo boxes from high inventory containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the robot moves the entire inventory container to the picking area, then the cargo boxes can be picked, but the robot's load increases and resources are wasted

Engineering Contradiction:

Improvecargo box pickingVSAvoidrobot load

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The system separates the inventory container from the cargo boxes by introducing a movable shelf that can be independently positioned. The robot only needs to move the shelf with selected cargo boxes, not the entire container, thereby segmenting the loading task and reducing robot load while maintaining picking functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The movable shelf acts as an intermediary between the inventory container and the robot. It receives cargo boxes from the container and presents them to the robot for picking, eliminating the need for the robot to directly handle the heavy container while still enabling efficient cargo box retrieval

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the cargo box conveying mechanism is integrated with the temporary storage mechanism, then the structure is compact, but the conveying mechanism cannot independently rise and fall

Engineering Contradiction:

Improvemechanism structureVSAvoidconveying mechanism independence

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system divides the lifting function into two independent parts: the temporary storage mechanism's lifting system and the cargo box conveying mechanism's lifting system. This segmentation allows each mechanism to be controlled independently, enabling the conveying mechanism to rise and fall autonomously to match different inventory container heights while maintaining overall structural compactness

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cargo box conveying mechanism is designed with dynamic lifting capability through its own lifting mechanism, allowing it to adjust its position independently of the temporary storage mechanism. This dynamic adjustment enables the conveying mechanism to adapt to varying inventory container heights and improve operational versatility

Inventive Principle:

Principle #15Dynamics

AI summary

A transfer robot comprises a movable chassis, a door frame vertically arranged on the movable chassis, and a temporary storage mechanism and a cargo box conveying mechanism which are arranged on the door frame, wherein the temporary storage mechanism is provided with a plurality of temporary storage spaces used for temporarily storing cargo boxes, and the cargo box conveying mechanism can stretch horizontally and lift vertically relative to the door frame so as to convey the cargo boxes between the temporary storage space and a temporary inventory container.
