Liquid Container Attachment Clamping Lever Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachments for liquid containers, such as beverage cans, face challenges in establishing a reliable, liquid-tight connection that withstands emptying and drinking without leaking, particularly due to difficulties in securing the attachment to the container's edge.
Innovation Solution
The proposed attachment features a clamping lever that extends through the bearing plane and container outlet, bearing against the inner side of the container to secure the attachment, combined with a reservoir and channel system for a secondary liquid, ensuring a sealing connection through elastic components and a passage for controlled liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attachment is secured by clamping on the edge of the container, then the attachment can be easily fixed, but the connection is not liquid-tight
Solution Approach 1:
The attachment is divided into separate functional components: a bearing surface for sealing, a clamping lever for securing, and a channel system for liquid flow. This segmentation allows each component to be optimized for its specific function, with the bearing surface providing liquid-tight sealing and the clamping lever providing secure mechanical attachment.
Solution Approach 2:
The bearing surface acts as an intermediary element between the attachment and the container. It provides a dedicated sealing interface that mediates the connection, ensuring liquid-tightness while the clamping lever applies the necessary clamping force. This intermediary bearing surface resolves the contradiction by separating the sealing function from the clamping function.
2Reliability
If the bearing surface is designed to connect via forces parallel to the outlet plane, then the connection may be stronger, but the sealing effectiveness is reduced
Solution Approach 1:
The bearing surface is designed with local quality characteristics - it is positioned and oriented specifically to bear against the container wall in a direction perpendicular to the outlet plane. This local optimization ensures that the bearing surface provides sealing effectiveness through proper orientation, while the clamping lever provides the necessary connection strength through a different mechanical action.
3Reliability
If the clamping lever extends through the bearing plane and container outlet, then the attachment security is improved, but the device complexity increases
Solution Approach 1:
The clamping lever is designed as a multi-functional element that simultaneously provides structural support, applies clamping force, and guides the attachment during installation. By making the clamping lever universal in its functions, the design reduces the need for additional separate components, thereby reducing overall device complexity while maintaining high attachment security.
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 design provides a secure, liquid-tight connection that allows for efficient emptying and mixing of liquids, reducing space and material usage while maintaining a consistent mix ratio, and is adaptable to various container sizes and shapes.
Implementation Method 1
The bearing surface is provided with a sealing material. The sealing material is preferably elastic and compensates for unevennesses in the container wall without the sealing effect of the bearing surface being lost.
