Welded Valve Assembly for Flexible Aerosol Container Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve arrangements for aerosol containers are inflexible and costly to produce, often requiring adjustments to the valve itself when switching between different valve plates made of plastic or metal.
Innovation Solution
A valve arrangement that uses a standard valve with a separate fastening part, which can be laser-welded or ultrasonically welded to a valve plate, allowing for the use of different valve plates without adjusting the valve, and can be friction-welded to a container, enabling cost-effective and flexible production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional valve arrangement is used with integrated valve and valve plate, then the valve is firmly connected to the container, but the production cost increases and flexibility decreases when switching between different valve plates
Solution Approach 1:
The valve arrangement is divided into separate components: a valve housing containing the valve element, and a separate fastening part that connects the valve housing to the valve plate. This segmentation allows the valve to be reused with different valve plates while maintaining secure connection, reducing production costs and increasing flexibility.
Solution Approach 2:
The valve housing with the separate fastening part serves as a universal component that can be attached to different valve plates (made of plastic or metal) without modification. This multi-functional design enables a single valve assembly to work with multiple valve plate types, eliminating the need for custom valve adjustments for each plate material.
2Adaptability or versatility
If a separate fastening part is used to connect the valve housing to the valve plate, then the flexibility to use different valve plates increases, but the device complexity increases
Solution Approach 1:
The fastening part is integrated with the valve housing as a unified assembly, where the fastening part is inserted into the valve housing and secured together. This merging reduces the number of separate components to handle during assembly, simplifying the overall device structure while maintaining the flexibility benefits of having a separate connectable fastening mechanism.
