Dual-Robot Warehousing for Tall Fixed and Portable Racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent warehousing systems face limitations in height, leading to restricted movement of warehousing robots and suboptimal warehouse space utilization, resulting in a low utilization rate.
Innovation Solution
The introduction of a dual-robot system comprising a first warehousing robot for fixed racks and a second warehousing robot for portable racks, along with a processing terminal that manages scheduling instructions and material storage association information to optimize material fetching and placement across different types of racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the warehousing robot moves a rack with material stored, then the material can be transported to the target position, but the height of the rack is limited to avoid dumping risk
Solution Approach 1:
The system divides the rack into two independent parts: a fixed rack that remains stationary and a portable rack that can be moved. The fixed rack provides stable support and can be made tall without dumping risks, while the portable rack contains the material and is moved separately by the robot. This segmentation allows the fixed rack to achieve greater height while maintaining reliability.
Solution Approach 2:
The fixed rack acts as an intermediary structure that provides stable support during the material transfer process. The portable rack is moved to and from the fixed rack, which serves as a stable platform. This intermediary structure enables the system to handle taller racks without dumping risks by providing a stable base during operations.
2Reliability
If the rack height is limited, then dumping risk is reduced, but the warehouse space utilization rate decreases
Solution Approach 1:
By segmenting the rack system into fixed and portable components, the invention enables the fixed rack to be made taller to improve space utilization, while the portable rack maintains manageable dimensions for safe handling. This resolves the contradiction by allowing greater overall storage capacity without compromising safety during robot operations.
Solution Approach 2:
The invention transitions from a single rigid rack structure to a two-component system with different functional dimensions. The fixed rack optimizes vertical space utilization, while the portable rack optimizes for mobility and safety. This dimensional differentiation allows the system to simultaneously achieve high warehouse utilization and safe operation.
3Device complexity
If a single type of warehousing robot is used, then the system structure is simplified, but the flexibility and adaptability to different rack configurations is reduced
Solution Approach 1:
The system employs two types of warehousing robots, each specialized for different rack types: one for fixed racks and another for portable racks. This multi-functionality approach allows the system to handle diverse rack configurations effectively, improving adaptability while maintaining manageable complexity through specialized design.
Solution Approach 2:
The system dynamically selects the appropriate robot type based on the rack configuration being operated. This dynamic adaptation allows the system to optimize performance for each specific task, balancing structural complexity with operational versatility by having different robots available for different scenarios.

AI summary
An intelligent warehousing system, a material fetching and placing method and a processing terminal thereof, where the intelligent warehousing system includes a first warehousing robot and a second warehousing robot, the first warehousing robot is configured to receive a first scheduling instruction, move to a fixed shelf to fetch and place a material box according to the first scheduling instruction, and handle the material box to a first target position; and the second warehousing robot is configured to receive a second scheduling instruction, move to a portable shelf according to the second scheduling instruction, and handle the portable shelf to a second target position. Through the technical solution of the present application, compatibility of the intelligent warehousing system is improved, which may be applied to a warehouse with different shelves, thus improving the utilization rate of the warehouse.
