Magnetic Mover Recovery Control for Contact-to-Float Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact type transport systems face challenges in efficiently transitioning a mover from a contact state to a floating state, particularly when abnormal sensor readings cause the mover to come into contact with the transport path.
Innovation Solution
The transport system incorporates a stator with magnetic force units and a mover with corresponding magnetic force units, along with a control unit that applies a rotational force to the mover to facilitate transition from a contact state to a floating state by using regulating members on the stator and mover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mover transitions from contact state to floating state using conventional control methods, then the mover can be floated, but the instantaneous power consumption increases and the transition process becomes complex
Solution Approach 1:
The patent applies preliminary action by performing a rotation process before the floating transition. The mover is rotated around a fulcrum (one of the regulating members) to bring it into contact with another regulating member, establishing a stable pivot point before applying the floating force. This preliminary rotation ensures that the subsequent floating transition requires less instantaneous power and occurs more smoothly.
Solution Approach 2:
The patent employs dynamics by using a two-stage transition process: first rotating the mover around a fulcrum to change its orientation and contact points, then transitioning to the floating state. This dynamic approach adapts the transition process based on the mover's contact state, ensuring reliable control while managing power consumption efficiently.
2Reliability
If the mover transitions from contact state to floating state using conventional methods, then the mover can be floated, but the transition process becomes complex and time-consuming
Solution Approach 1:
The rotation process serves as a preliminary action that prepares the mover for the floating transition. By rotating the mover around a fulcrum to establish contact with another regulating member first, the system creates an optimal starting position for the floating transition, making the overall process more efficient and reliable.
Solution Approach 2:
The transition process is segmented into distinct stages: rotation around a fulcrum, contact with the second regulating member, and then floating transition. This segmentation allows each stage to be controlled independently and optimally, improving overall transition reliability while managing time consumption.
3Stability of the object's composition
If the mover contacts the transport path during operation, then the mover can be stabilized, but damage may occur during the transition back to floating state
Solution Approach 1:
The patent applies beforehand cushioning by using the rotation process around a fulcrum as a protective measure. The regulated rotation around a stable fulcrum point and the controlled contact with the second regulating member cushion the transition process, preventing sudden impacts or unstable movements that could cause damage during the return to floating state.
Solution Approach 2:
The rotation around a fulcrum serves as a preliminary protective action that prepares the mover for safe floating transition. By establishing a controlled rotation process first, the system ensures that the subsequent floating transition occurs from a stable, controlled state, reducing the risk of damage.
