Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closing systems in clean rooms face challenges with high costs and germ/soiling penetration due to the need for large magnetic couplings to transmit forces, which also increase moving masses and complexity.
Innovation Solution
A container closer design where the closing head is connected directly to the rotor of an electric motor, with a non-magnetic element for clean room separation between the rotor and stator, allowing forces to be transmitted through the magnetic field without additional couplings, reducing costs and germ/soiling ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic couplings are used to transmit forces from the motor to the closing head, then hermetic separation of the clean room is achieved, but the moving masses increase and costs rise due to large dimensions
Solution Approach 1:
The patent merges the hermetic separation function with the motor structure by placing the clean room separation element directly between the stator and rotor. This integration eliminates the need for separate magnetic couplings, reducing moving masses while maintaining hermetic separation. The magnetic field transmits forces through the separation element itself, combining two functions into one component.
Solution Approach 2:
The patent extracts the magnetic coupling from the force transmission path and replaces it with direct magnetic field action through the clean room separation element. By removing the intermediate magnetic coupling components, the moving masses are reduced while the hermetic separation function is preserved through the integrated design.
2Reliability
If magnetic couplings are used to transmit forces from the motor to the closing head, then hermetic separation of the clean room is achieved, but manufacturing costs increase due to large dimensions
Solution Approach 1:
The patent combines the hermetic separation function with the motor structure by integrating the clean room separation element between the stator and rotor. This merger eliminates the need for separate, expensive magnetic couplings, reducing manufacturing costs while maintaining hermetic separation. The magnetic field transmits forces through the integrated separation element, consolidating two functions into one cost-effective component.
Solution Approach 2:
The patent removes the expensive magnetic coupling components from the force transmission path and replaces them with direct magnetic field action through the integrated clean room separation element. This extraction of unnecessary components reduces manufacturing complexity and costs while preserving the hermetic separation function.
3Object-affected harmful factors
If additional sealing devices are installed to prevent germ and soiling penetration, then clean room protection is improved, but device complexity increases
Solution Approach 1:
The patent merges the hermetic separation function with the motor structure by placing the clean room separation element directly between the stator and rotor. This integration eliminates the need for additional sealing devices like shaft sealing rings or siphon sealings, reducing device complexity while maintaining protection against germ and soiling penetration. The magnetic field acts through the integrated separation element, combining structural and protective functions.
Solution Approach 2:
The patent extracts and eliminates the need for additional sealing devices by integrating the hermetic separation function into the motor structure itself. The clean room separation element between the stator and rotor provides the necessary protection without requiring separate sealing components, simplifying the overall device design.
