Problem
The setup of collaborative robots is often inaccurate and cumbersome, lacking efficient tools to facilitate precise positioning and secure mounting in shared workspaces.
Innovation Solution
A robot setup device featuring a moving cart with a robot arm, roller blocks, and a guide pin, along with a setup device that includes guide walls and anchor shafts, allows for precise alignment and secure positioning of the moving cart on the setup device, utilizing roller mounts with curved sides to form inflection points for stable contact with anchor shafts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional setup methods are used for collaborative robots, then the setup process is simple, but the positioning accuracy and mounting precision are insufficient
Solution Approach 1:
The patent introduces a moving cart as an intermediary device between the robot and the floor. The moving cart includes a cabinet with roller blocks and a guide pin, serving as a mediator that enables precise positioning and easy movement. This intermediary structure resolves the contradiction by providing accurate positioning capability without requiring complex direct mounting mechanisms.
Solution Approach 2:
The roller blocks incorporate curved surfaces that form inflection points with respect to the outer circumference of the rollers. This curvature design allows the roller blocks to smoothly engage with anchor shafts during positioning, improving mounting precision while maintaining a relatively simple device structure.
2Ease of operation
If the robot arm is directly mounted on a fixed base, then the structure is stable, but the setup process is cumbersome and time-consuming
Solution Approach 1:
The patent transforms the static fixed base into a dynamic moving cart structure. The cabinet is equipped with roller blocks that can rotate, allowing the cart to be easily moved and repositioned during setup. This dynamic design enables quick adjustments and reconfigurations, significantly reducing setup time while maintaining operational ease.
Solution Approach 2:
The guide pin is pre-positioned on the cabinet before the robot arm is mounted. This preliminary positioning action guides the cabinet to the correct location and orientation, eliminating the need for time-consuming adjustments during the actual mounting process. The pre-configured guide pin ensures rapid and accurate setup.
3Adaptability or versatility
If the robot is designed for fixed installation, then the structural stability is high, but the adaptability to different workspace configurations is limited
Solution Approach 1:
The patent divides the robot system into separable components: the robot arm, the cabinet, and the roller blocks. This segmentation allows each component to be independently positioned and configured. The cabinet can be moved to different locations using the roller blocks, providing adaptability to various workspace configurations while maintaining structural stability when assembled.
Solution Approach 2:
The moving cart design serves multiple functions: it provides a mounting base for the robot arm, enables easy movement and repositioning, and offers stable operation when installed. This multi-functional design enhances workspace adaptability without compromising structural stability, allowing the same structure to accommodate different configuration needs.
4Manufacturing precision
If conventional mounting methods are used, then the installation process is straightforward, but the positioning precision and secure mounting are insufficient
Solution Approach 1:
The roller blocks serve as intermediary mounting elements between the cabinet and the floor. These roller blocks with their curved surfaces provide precise positioning during installation, ensuring accurate mounting without requiring complex alignment procedures. The intermediary structure simplifies the installation process while maintaining high mounting precision.
Solution Approach 2:
The curved surfaces of the roller blocks that form inflection points enable smooth engagement with anchor shafts during mounting. This curvature design automatically guides the roller blocks into the correct position, achieving precise mounting without complex alignment tools or procedures, thus maintaining installation simplicity.
