Bayonet Coupling for Flowable Media Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport systems for pourable and flowable media often fail to maintain contamination-free operation and have a short service life due to jamming issues with fine powders and dust-like substances, leading to increased costs and reduced efficiency in the pharmaceutical and chemical industries.
Innovation Solution
The transport system employs film tubes connected via welding at branching points, allowing for a continuous transport route with a locking mechanism that enables easy replacement of connection parts, reducing contamination risks and extending the system's service life by allowing multiple filling and emptying cycles before replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If profile strips with locking elements are used for coupling, then the coupling device can be quickly assembled and disassembled, but fine powder and dust-like substances cause jamming that prevents further coupling operations
Solution Approach 1:
The invention extracts and removes the problematic locking elements (profile strips with interlocking hooks) from the coupling device. Instead, it uses a simple bayonet-style coupling mechanism with a single rotating locking element that is much less susceptible to jamming by fine powders and dust-like substances, while maintaining quick assembly and disassembly capabilities.
Solution Approach 2:
The invention changes the coupling mechanism from a complex multi-element profile strip system to a simplified bayonet-style system with different geometric parameters. The new design features a coupling body with a single axial opening and a locking element that rotates into a locking position, fundamentally altering the coupling parameters to reduce sensitivity to contamination.
2Object-affected harmful factors
If interlocking coupling rings are used to connect flexible containers, then contamination-free transport is achieved, but very fine dust-like powder settles on hose sections outside the coupling engagement complicating further operations
Solution Approach 1:
The invention introduces a coupling body as an intermediary component that provides a sealed coupling interface. The coupling body with its coupling opening and locking mechanism acts as a mediator between containers, maintaining contamination-free transport while the simplified locking mechanism prevents powder settlement issues that complicate operations with traditional interlocking ring systems.
3Loss of time
If traditional coupling devices are used, then initial coupling operations work, but service life is short due to jamming issues requiring frequent dismantlement and disposal
Solution Approach 1:
The invention reverses the disposable approach by creating a durable, reusable coupling device. Instead of disposing of the entire system after short use, the coupling body with its simplified locking mechanism is designed for long-term reuse, resisting jamming and contamination to extend service life significantly while reducing disposal frequency.
4Ease of operation
If profile strip connection systems are used, then coupling can be achieved, but dust-like powder unintentionally released during operation complicates or prevents further coupling
Solution Approach 1:
The invention extracts and eliminates the problematic profile strip connection system that causes powder release. The new bayonet-style coupling mechanism with its single rotating locking element operates with much less friction and mechanical complexity, preventing the unintentional release and settlement of dust-like powder that occurs with traditional profile strip systems.
