Connection System Blocking Mechanism for Sterile Compartment Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connection systems for isolating environments with different contamination grades are vulnerable to manipulation errors, leading to potential contamination between environments, as the inner removable closing device can be inadvertently removed without ensuring the connecting element is securely positioned, compromising the sterility of the compartment.
Innovation Solution
A connection system with a blocking device that includes a control element with a first open position for inserting the connecting element and a second closing position to secure it, featuring a blocking mechanism that maintains the control element in a closed position during the removal of the inner removable closing device, ensuring the connecting element remains sealed against the connecting wall, even when the removable closing device is no longer present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner removable closing device is made removable to allow case removal, then ease of operation is improved, but reliability deteriorates due to risk of inadvertent removal and contamination
Solution Approach 1:
The blocking mechanism is activated in advance before the inner removable closing device is completely removed. When the device begins to be pulled out, the blocking mechanism automatically engages to hold the connecting element in place, preventing accidental disengagement and maintaining sealing reliability throughout the removal process.
Solution Approach 2:
The blocking mechanism acts as an intermediary between the inner removable closing device and the connecting element. It mediates the transition from a secure connected state to a removed state, ensuring that the connecting element remains blocked and sealed until the proper removal sequence is completed.
2Ease of operation
If the connecting element is easily insertable and removable, then ease of operation is improved, but reliability worsens due to potential disengagement and contamination
Solution Approach 1:
The blocking mechanism dynamically adjusts its state based on the position of the inner removable closing device. When the device is inserted, the blocking mechanism is inactive allowing easy insertion. When the device is removed, the blocking mechanism automatically activates to maintain connection stability, providing dynamic control over the connecting element's state.
3Reliability
If the blocking mechanism activates automatically during removal, then reliability is improved, but device complexity increases
Solution Approach 1:
The blocking mechanism is designed to activate automatically without requiring external intervention or complex control systems. The removal action of the inner removable closing device itself triggers the blocking mechanism, making the system self-regulating and reducing the need for additional actuators or control logic.
