Movable Column Frame for Height-Adaptive Transport Robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transport robots in intelligent warehousing have fixed column heights, limiting their ability to carry goods that exceed these heights, and they lack adjustable height capabilities, making them inefficient in various spaces.
Innovation Solution
A method and device for controlling a transport robot with a vertical support system that includes a fixed column frame and a movable column frame. The carrying device is mounted on the movable column frame, which can ascend or descend through the traction assembly and retractable assembly, allowing the transport robot to reach higher carrying positions and adapt to different spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fixed column frame is used with a fixed height, then the structure is simple and stable, but the carrying device cannot reach higher positions and cannot adapt to different spaces
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed column frame into a movable column frame that can ascend and descend along the fixed column frame. This dynamic adjustment mechanism allows the carrying device to reach different heights and adapt to various storage spaces, resolving the contradiction between structural simplicity and height adaptability.
Solution Approach 2:
The patent implements the nesting principle by placing the movable column frame inside the fixed column frame, where the movable column frame can slide vertically along the fixed column frame. This nested structure enables height adjustment while maintaining a compact and relatively simple overall structure, addressing both adaptability and structural complexity concerns.
2Length of moving object
If the carrying device is limited to a fixed stroke, then the structure is simple, but it cannot carry goods that exceed the fixed column height
Solution Approach 1:
The patent uses the movable column frame as an intermediary mechanism between the fixed column frame and the carrying device. The movable column frame, driven by the traction and retractable assemblies, extends the reaching capability of the carrying device to higher positions without requiring direct structural changes to the carrying device itself, thus managing the complexity while achieving greater height.
Solution Approach 2:
The patent segments the vertical support system into two independent parts: the fixed column frame and the movable column frame. This segmentation allows the movable column frame to be independently controlled by the traction and retractable assemblies, enabling height adjustment while keeping each component relatively simple in structure.
3Productivity
If the transport robot has a fixed height configuration, then the device complexity is low, but the productivity is reduced due to inability to access different storage levels
Solution Approach 1:
The patent applies dynamics by enabling the movable column frame to ascend and descend along the fixed column frame, allowing the transport robot to access goods at different heights. This dynamic height adjustment capability significantly improves productivity by enabling the robot to retrieve and transport goods from various storage levels, while the height adjustment mechanism maintains relatively controlled complexity through the use of standard traction and retractable assemblies.

AI summary
A vertical support for a transport robot includes a column assembly and a driving assembly. The vertical support includes a fixed column frame and a movable column frame movably arranged on the fixed column frame. The driving assembly includes a traction assembly and a retractable assembly connected to the traction assembly. The traction assembly is connected to the carrying device and configured to drive a carrying device of the transport robot to move relative to the movable column frame. The traction assembly includes two sets of traction assemblies located at two opposed sides of the carrying device respectively, the retractable assembly is configured to drive the two sets of the traction assemblies to synchronously drive the carrying device to ascend or descend.
