Welded Valve Plate Fixing for Versatile Aerosol Valve Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve arrangements for aerosol containers are inflexible and costly to produce, as they often require adaptation of the valve itself to accommodate different valve plates, limiting the use of conventional valves and increasing production complexity.
Innovation Solution
A valve arrangement that uses a separate fixing part, which can be friction-welded or laser-welded with the valve plate, allowing for the use of standard valves with different valve plates made of plastic or metal, enabling flexible and cost-effective production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the valve is adapted to accommodate different valve plates, then the versatility is improved, but the device complexity and production cost increase
Solution Approach 1:
The valve arrangement is divided into separate functional components: a standard valve unit and a valve plate with an integrated fixing part. The fixing part is formed as a separate element (such as a ring, flange, or protrusion) on the valve plate, allowing the valve and valve plate to be manufactured independently and assembled together. This segmentation enables the valve to remain standardized while the valve plate adapts to different configurations.
Solution Approach 2:
The fixing part acts as an intermediary element between the valve and the valve plate. It provides a standardized interface (through features like through-holes, recesses, or welding surfaces) that mediates the connection between the standard valve and various valve plate designs, enabling versatility without requiring customization of the valve itself.
2Adaptability or versatility
If the valve is adapted to accommodate different valve plates, then the versatility is improved, but the production cost increases
Solution Approach 1:
By segmenting the fixing part as a separate feature on the valve plate rather than integrating it into the valve, the valve can be mass-produced as a standard component. The valve plate is manufactured with the fixing part already incorporated, allowing both components to be produced efficiently through standard manufacturing processes without requiring costly customization of the valve for each application.
Solution Approach 2:
The standard valve design with the fixing part on the valve plate creates a universal interface that can be used across multiple applications and valve plate designs. This universality reduces production costs by eliminating the need for custom valve adaptations while maintaining versatility through different valve plate configurations.
3Ease of manufacture
If a separate fixing part is used to connect the valve housing to the valve plate, then the ease of manufacture is improved, but the device complexity increases
Solution Approach 1:
The fixing part is merged with the valve plate as an integrated feature (such as a ring, flange, or protrusion formed directly on the valve plate). This merging reduces the total number of separate components while still providing the necessary connection functionality, thereby simplifying the overall device structure despite the added manufacturing flexibility.
Solution Approach 2:
The fixing part is designed to perform multiple functions: it serves as both a structural element of the valve plate and a connection interface for the valve. Features like through-holes, recesses, or welding surfaces are self-integrated into the fixing part design, eliminating the need for additional fastening components or complex assembly steps.
