Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for moving containers within clean rooms are either not versatile or too complex, failing to provide a reliable and simple solution for maintaining sterility and preventing contamination while minimizing the clean room's volume.
Innovation Solution
An apparatus comprising a first linear guide in a controlled-contamination environment, a rotatably coupled carriage, a second linear guide in a separate environment, and a magnetic or electromagnetic coupling between the carriage and slider, with a separation wall maintaining environmental separation and allowing for versatile and reliable container treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drive systems and transport elements are arranged within the clean room, then container treatment operations can be performed, but the clean room volume increases and contamination risk increases at interfaces
Solution Approach 1:
A magnetic coupling mechanism acts as an intermediary between the external drive system and the internal carriage, enabling force transmission without physical penetration of the separation wall. The drive system remains outside the clean room while the carriage operates inside, with magnetic fields bridging the boundary to transmit motion without compromising clean room integrity or increasing its volume.
2Ease of operation
If drive systems penetrate the separation wall to enter the clean room, then container treatment can be performed, but contamination risk increases
Solution Approach 1:
The magnetic coupling mechanism serves as a non-invasive intermediary that transmits drive forces through the separation wall without creating physical openings or penetration points. This eliminates contamination pathways while enabling full container treatment functionality within the clean room environment.
Solution Approach 2:
Physical mechanical penetration of the separation wall is replaced by a magnetic field-based transmission system. The drive system operates externally and couples magnetically to the carriage, substituting direct mechanical contact with field-based interaction that preserves the separation wall's integrity and prevents contamination.
3Device complexity
If a simple transport mechanism is used, then device complexity is reduced, but versatility in container treatment operations is limited
Solution Approach 1:
The carriage is designed as a universal platform that can perform multiple container treatment operations including transport, sterilization, filling, and sealing. By integrating these diverse functions into a single multi-functional unit that moves along simple linear guides, the system achieves high versatility without proportionally increasing overall complexity.
