Motion Automaton Setup Using Guided Safe Motion Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic movement machines often exceed safety-relevant speed limits or working ranges during setup, posing risks to nearby personnel due to their dynamic nature and lack of controlled movement guidance.
Innovation Solution
A method involving coupling a movable element of the movement machine to a multi-part guide robot, exerting force to guide it along a predetermined course, and decoupling it from its drive device to prevent unintended movement, using a guide device like a SCARA robot to record setup data and ensure the element moves within defined speed and acceleration profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motion automaton is operated during setup, then the setup process can be completed, but the machine may exceed safety-relevant speed limits and working ranges
Solution Approach 1:
A guide device is introduced as an intermediary between the operator and the motion automaton during setup. The guide device physically guides the motion automaton along predetermined safe paths, ensuring that speed limits and working ranges are not exceeded while still allowing the setup process to be completed
Solution Approach 2:
Predetermined motion paths are established before the setup process begins. These pre-planned paths ensure that the motion automaton will only move within safe parameters, preventing exceedance of speed limits and working ranges before any harmful movements can occur
2Ease of operation
If the movable element is coupled to the drive device during setup, then the motion automaton can be controlled, but unintended movements and loss of control may occur
Solution Approach 1:
The coupling between the movable element and drive device is made dynamic rather than static. The movable element can be selectively coupled to and decoupled from the drive device depending on the setup phase, allowing controlled movement when needed while preventing unintended movements when the drive device should not be active
3Measurement precision
If the movable element is actively driven during setup, then positioning can be achieved, but energy consumption increases and control becomes more difficult
Solution Approach 1:
The drive device operates periodically rather than continuously during setup. The movable element is actively driven only when positioning is required, then decoupled and allowed to move passively under gravity or external forces, reducing overall energy consumption while maintaining positioning accuracy when needed
