Break-Off Aluminum Hose Plug for Recyclable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional aluminum hoses require a plastic cover for sealing, which becomes impurity during recycling and affects the quality of secondary smelting, and although pure aluminum covers are available, they are too expensive for large-scale promotion.
Innovation Solution
A one-time punch formed aluminum hose with a head that can be broken and used as a plug, featuring an extrusion head, a plugging head, and a broken part integrally formed with the hose, allowing the plugging head to be separated and used for sealing without the need for a plastic cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic cover is used for sealing the aluminum hose, then the sealing function is achieved, but the plastic cover becomes impurity during recycling and affects the quality of secondary smelting
Solution Approach 1:
The invention uses a plugging head made of the same aluminum material as the hose body, ensuring material homogeneity. This allows the entire structure to be recycled together without contamination from different materials, eliminating the plastic impurity problem while maintaining the sealing function through the breakable plugging head design
2Object-generated harmful factors
If a pure aluminum cover is used instead of plastic cover, then the recycling compatibility is improved, but the cost increases significantly
Solution Approach 1:
The invention merges the plugging head with the hose body by using the same aluminum material and integral formation process. This combination eliminates the need for separate expensive pure aluminum covers while maintaining recycling compatibility, as the plugging head becomes part of the hose structure that can be recycled together
Solution Approach 2:
The plugging head serves multiple functions: it provides sealing when intact, can be broken to open the hose, and is made of the same material as the hose for unified recycling. This multi-functionality replaces the need for separate expensive covers while maintaining all required functions
3Ease of operation
If a breakable plugging head design is used, then the ease of operation is improved, but the structural complexity increases
Solution Approach 1:
The invention segments the hose end into distinct functional parts: the extrusion head for material extrusion, the broken part as a separation zone, and the plugging head for sealing. This segmentation allows the plugging head to be easily broken off for opening while maintaining a relatively simple overall structure through integral formation

AI summary
What the present invention discloses belongs to the technical field of aluminum hoses, and in particular relates to a one-time punch formed aluminum hose whose head can be broken and used as a plug. A broken part is provided between an extrusion head and a plugging head, so that the connection between the extrusion head and the plugging head is relatively “fragile”. A user breaks the broken part to realize the separation of the plugging head from the extrusion head, and at the same time, the other end of the plugging head is inserted into an extrusion port and is in an interference fit with the extrusion port, thus achieving the effect of plugging.
