Robot Stopper Mechanism for Compact Space Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots face challenges in limiting the movement range of movable components due to space constraints, as they require multiple stoppers along the moving trajectory, which can be difficult to install in compact robots.
Innovation Solution
A robot design that uses a single first stopper and a second stopper, configured to contact each other along an axis parallel to the movement direction, allowing for adjustable movement range limitation without the need for multiple physical stoppers, enabling flexible installation even in space-constrained environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple stoppers are provided at multiple positions to limit the movement range of a movable component, then the movement range can be effectively limited, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple stopper functions into a single stopper structure by providing a stopper with multiple stopper portions extending in different directions. This single integrated stopper performs the function of multiple separate stoppers, thereby limiting the movement range of the movable component effectively while reducing the number of individual stopper components needed in the system
Solution Approach 2:
The stopper is designed with multi-functionality by incorporating multiple stopper portions (first stopper portion, second stopper portion, etc.) that can limit movement in different directions or against different components. This universal stopper structure can serve multiple limiting functions simultaneously, replacing what would traditionally require multiple separate stoppers installed at different positions
2Reliability
If multiple stoppers are installed along the moving trajectory, then the movement range can be limited, but the installation space requirements increase which is problematic for compact robots
Solution Approach 1:
The patent merges multiple stopper functions into a single stopper assembly that occupies less installation space. By integrating multiple stopper portions into one structure, the required installation area along the moving trajectory is reduced, making it suitable for compact robot designs where space is limited
Solution Approach 2:
The stopper portions extend in different directions (different dimensions) from a common mounting location rather than being distributed along the entire moving trajectory. This dimensional arrangement allows the stopper to limit movement in multiple directions from a single installation point, reducing the linear space required along the movement path

AI summary
A robot that enables a stopper to be installed even when it is difficult to allow a space for providing the stopper. The robot includes a first component; a second component movably coupled to the first component; a first stopper provided on one of the first component and the second component, the first stopper extending along an axis parallel to a movement direction of the second component relative to the first component; and a second stopper provided on the other of the first component and the second component, the second stopper configured to come into contact with the first stopper when the second component moves relative to the first component and limit a movement range of the second component relative to the first component.
