Magnetic Coupling Carriage for Sealed Tablet Elevator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tablet elevators in industrial processes face contamination issues due to exposure of lifting mechanisms to ambient air, leading to time-consuming cleaning requirements, especially when switching between different products.
Innovation Solution
A magnetic coupling system for moving a receptacle, comprising an internal and external carriage magnetically coupled across a coupling wall, allowing movement of the external carriage without direct contact, and a sealed enclosure to protect the actuator from contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lifting mechanism is exposed to ambient air for easy access and operation, then ease of operation is improved, but contamination from dust and environmental factors increases
Solution Approach 1:
The system is divided into two separate carriages: an internal carriage that operates within the sealed enclosure and an external carriage that interfaces with the ambient environment. The coupling wall separates these two segments, allowing each to be optimized for its specific environment while maintaining functional connection through magnetic coupling.
Solution Approach 2:
The coupling wall acts as an intermediary barrier between the sealed internal environment and the external ambient environment. It transmits motion magnetically while preventing physical contact and contamination, serving as a mediator that allows force transmission without matter exchange.
2Reliability
If thorough cleaning is performed to remove contamination and grease, then purity is improved, but time consumption increases
Solution Approach 1:
The actuator and critical lifting components are extracted from the ambient environment and placed inside a sealed enclosure. This extraction protects these components from contamination in the first place, eliminating the need for frequent cleaning operations.
Solution Approach 2:
The sealed enclosure design makes the system self-maintaining by preventing contamination entry. The magnetic coupling mechanism allows the external carriage to be easily removed and replaced without disassembling the sealed internal components, enabling quick changes without thorough cleaning.
3Object-affected harmful factors
If the lifting mechanism is sealed to prevent contamination, then contamination resistance is improved, but access for operation and maintenance becomes difficult
Solution Approach 1:
The magnetic coupling system replaces direct mechanical connection between internal and external carriages. This substitution allows the sealed enclosure to remain intact while still enabling motion transmission, as magnetic fields can penetrate the coupling wall without physical openings.
4Ease of operation
If magnets are used to couple internal and external carriages, then contactless transmission is achieved, but magnetic interference with surrounding components may occur
Solution Approach 1:
The magnetic coupling is localized to specific regions where the internal and external carriages interface with the coupling wall. Magnets are positioned only where needed for motion transmission, minimizing the spatial extent of magnetic fields and reducing potential interference with other components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system enables efficient and reduced contamination risk during product transitions, simplifying cleaning operations by maintaining the actuator within a sealed environment, thus minimizing exposure to dust and other environmental factors.
Implementation Method 1
The internal and external carriages are magnetically coupled to each other across the coupling wall so that when the internal carriage is moved along the predetermined path, the external carriage follows the internal carriage and remains substantially in register therewith

AI summary
A system for moving a receptacle. The system includes: a coupling wall; an internal carriage provided substantially adjacent the coupling wall, the internal carriage being movable along the coupling wall along a predetermined path; an external carriage provided substantially adjacent the coupling wall and substantially in register with the internal carriage with the coupling wall extending between the internal and external carriages, the external carriage being movable along the coupling wall, the external carriage including a receptacle attachment for securing the receptacle thereto; and a carriage actuator operatively coupled to the internal carriage for moving the internal carriage along the predetermined path. The internal and external carriages are magnetically coupled to each other across the coupling wall so that when the internal carriage is moved along the predetermined path, the external carriage follows the internal carriage and remains substantially in register therewith.
