Welded Valve Plate Assembly for Flexible Aerosol Valve Mounting
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 itself is adapted to accommodate different valve plates, then the valve arrangement can be used with various valve plates, but the production complexity and cost increase
Solution Approach 1:
The valve arrangement is divided into separate components: a standard valve unit and a valve plate, connected through a receiving space and securing elements. This segmentation allows the valve to remain unchanged while the valve plate adapts to different configurations, reducing production complexity while maintaining versatility
Solution Approach 2:
The valve plate serves multiple functions: it closes the container opening, provides a receiving space for the valve, and can be selectively produced in different materials (plastic or metal). This universal design allows the same valve to be used with different valve plates, enhancing adaptability without increasing valve complexity
2Adaptability or versatility
If the valve itself is adapted to accommodate different valve plates, then the valve arrangement can be used with various valve plates, but the production cost increases
Solution Approach 1:
By separating the valve from the valve plate and using a standardized valve unit, the invention enables independent production of each component. This allows economies of scale in valve manufacturing while valve plates can be produced cost-effectively in different materials as needed
Solution Approach 2:
The valve plate can be produced as a simpler, potentially disposable component in different materials (plastic or metal) depending on application requirements, while the expensive valve remains unchanged. This reduces overall production cost while maintaining versatility
3Ease of manufacture
If a separate fixing part is used to fix the valve housing to the valve plate, then the production becomes simpler and more cost-effective, but the device structure becomes more complex
Solution Approach 1:
The fixing part integrates multiple functions: it secures the valve housing to the valve plate, provides friction-welding surfaces, and enables laser-welding connections. By combining these functions into a single component, the invention reduces the number of separate parts while maintaining structural integrity
Solution Approach 2:
The fixing part acts as an intermediary element between the valve housing and valve plate, providing standardized welding surfaces and connection points. This intermediary component simplifies assembly while the chosen welding method (friction-welding or laser-welding) determines the final structural characteristics
