Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transfer robots with multi-stage gantries used in storage systems experience instability when handling high-level containers, leading to failure in handling tasks due to shaking.
Innovation Solution
A transfer robot design incorporating a chassis assembly, lifting device, pick-and-place assembly, and auxiliary support device with a driving assembly, transmission assembly, and support assembly that extends to stabilize the robot by abutting against carriers at two sides, enhancing stability during container handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transfer robot with multi-stage gantry is used to pick and place high-level containers, then the robot can access high-level containers, but the robot becomes unstable and shakes during handling
Solution Approach 1:
The patent introduces an auxiliary support device as an intermediary element between the robot and the carrier. This support device includes a support assembly that extends to abut against the carrier, providing external support to stabilize the robot during container handling operations at high levels.
Solution Approach 2:
The support assembly is designed to be dynamically adjustable, extending and retracting based on the operational requirements. The driving assembly and transmission assembly enable the support assembly to adjust its position relative to the pick-and-place assembly, allowing the robot to adapt its stability configuration during different phases of container handling.
2Stability of the object's composition
If the auxiliary support device extends to abut against carriers for stabilization, then robot stability improves, but the device complexity increases
Solution Approach 1:
The auxiliary support device is integrated into the existing robot structure in a nested manner. The support assembly, when not in use, can be retracted or folded within the overall robot configuration, minimizing the increase in device complexity while providing stabilization when needed.
Solution Approach 2:
The auxiliary support device serves multiple functions: it stabilizes the robot during container handling, supports the pick-and-place assembly, and can be adjusted for different operational scenarios. This multi-functionality reduces the need for separate stabilization mechanisms, thereby limiting the increase in overall device complexity.
3Stability of the object's composition
If the support assembly extends to abut against carriers, then handling stability improves, but the robot's outline size increases
Solution Approach 1:
The support assembly is designed with dynamic extension capability, allowing it to extend only when needed for stabilization during container handling. When not in use, the support assembly can be retracted, maintaining a compact robot outline size. The driving assembly and transmission assembly enable this dynamic adjustment of the support assembly's position.

AI summary
The transfer robot includes: a chassis assembly, a lifting device arranged on the chassis assembly, and a pick-and-place assembly arranged on the lifting device. The pick-and-place assembly is configured to ascend or descend along the lifting device. The auxiliary support device is arranged at the pick-and-place assembly and includes a driving assembly, a transmission assembly, and a support assembly. The driving assembly is connected to the support assembly by the transmission assembly to drive the support assembly to extend in a first direction relative to the pick-and-place assembly until the support assembly abuts against or separates from carriers at two sides of the transfer robot. The auxiliary support device is arranged on the pick-and-place assembly and is configured to extend to a position abutting against the carriers to support the transfer robot in the process of picking up and placing a container.
