Handling Robot Telescopic Retrieval With Multi-Level Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling robots in intelligent warehousing systems have limited capacity to load inventory items and are inefficient in their operation, as they can only handle a small number of items due to constraints in design and functionality.
Innovation Solution
A handling robot equipped with a telescopic arm, manipulator, and lifting assembly that extends along a preset horizontal reference line to load and unload inventory items from a warehouse shelf to a storage frame, allowing for efficient movement and storage of multiple items by adjusting its posture based on detected position information and using a temporary storage unit for height alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing handling robot design is used, then the robot can operate in intelligent warehousing, but the quantity of inventory items that can be loaded is too few and efficiency is low
Solution Approach 1:
The patent transitions from horizontal stacking to vertical stacking of inventory items on the storage frame. By utilizing the vertical dimension with multiple levels (first level, second level, etc.), the robot can load significantly more items within the same horizontal footprint, thereby increasing both the quantity of items loaded and loading efficiency
2Extent of automation
If manual handling of inventory items is replaced by handling robot, then automation is improved, but the capacity and efficiency remain limited
Solution Approach 1:
The storage frame is divided into multiple levels (first level, second level, etc.), with each level capable of holding multiple inventory items. This segmentation allows the robot to systematically load and manage a larger quantity of items across different vertical levels, enhancing both automation capability and handling efficiency
3Device complexity
If storage frame with limited vertical space is used, then device complexity is reduced, but the number of storage units and loading capacity are limited
Solution Approach 1:
The patent maximizes vertical space utilization by creating multiple storage levels within the storage frame. Instead of expanding horizontally, the design stacks inventory items vertically across multiple levels, significantly increasing storage capacity without proportionally increasing device complexity

AI summary
A method for retrieving an inventory item based on a handling robot, where the handling robot includes: a storage frame; and a material handling device installed on the storage frame, and including a telescopic arm and a manipulator installed to the telescopic arm; and the method for retrieving an inventory item includes: driving, by the telescopic arm, the manipulator to extend to a preset position of warehouse shelf along a preset horizontal reference line; loading, by the manipulator that is remained on the reference line, the inventory item located in the preset position; driving, by the telescopic arm, the manipulator loaded with the inventory item to move to the storage frame along the reference line; and unloading, by the manipulator that is remained on the reference line, the inventory item to the storage frame.
