Aerosol Valve Stabilizing Member Snap-Fit Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol containers require complex and time-consuming crimping processes to seal the valve cup, which is costly and limits design flexibility and emission control.
Innovation Solution
A stabilizing member with a resilient portion for snap fitting into a groove and a radial projection for sealing, eliminating the need for a valve cup by forming an upper valve housing that securely attaches to the aerosol container without the need for crimping, allowing for simpler and cost-effective manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve cup is used to seal the aerosol container, then sealing reliability is improved, but device complexity and manufacturing time increase due to the complex crimping process
Solution Approach 1:
The patent removes the valve cup component entirely from the aerosol container system. Instead of using a separate valve cup that requires crimping, the invention integrates the sealing function directly into the valve assembly through the stabilizing member with resilient portions that engage with the container neck, eliminating the need for the valve cup and its associated complex crimping process while maintaining sealing reliability
Solution Approach 2:
The patent combines the sealing function and stabilizing function into a single integrated component - the stabilizing member with resilient portions. This merging of functions eliminates the need for separate sealing components like the valve cup, simplifying the overall structure while ensuring both stable valve positioning and reliable sealing against the container neck
2Reliability
If a valve cup with crimping process is used, then sealing is achieved, but productivity decreases due to time-consuming manufacturing
Solution Approach 1:
The stabilizing member with resilient portions is designed to self-seal and self-stabilize when inserted into the container neck. The resilient portions automatically engage with the container neck surface, creating both sealing and stabilizing effects without requiring external crimping equipment or complex assembly processes, thereby dramatically improving manufacturing speed and productivity
Solution Approach 2:
The patent replaces the mechanical crimping system (requiring specialized equipment and multiple steps) with a simple insertion and elastic engagement system. The resilient portions provide automatic sealing through elastic deformation when inserted into the container neck, eliminating the need for complex mechanical crimping equipment and multi-step assembly processes
3Ease of manufacture
If a stabilizing member with radial projection sealing against inner wall is used, then ease of manufacture is improved, but sealing reliability may worsen if the projection does not seal against the container
Solution Approach 1:
The patent applies different sealing mechanisms at different locations of the stabilizing member: the resilient portions at the upper end engage with the container neck for sealing, while the radial projection at the lower end seals against the inner wall of the container. This local differentiation of sealing functions ensures both ease of assembly and reliable sealing at multiple critical locations
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 solution enables the production of aerosol containers with improved design flexibility, reduced emissions, and a more efficient manufacturing process, as the stabilizing member securely seals the aerosol valve without the need for crimping, enhancing product chain efficiency and reducing production costs.
Implementation Method 1
a resilient portion arranged at the periphery of said stabilizing member for snap fitting in a groove
Implementation Method 2
the radial projection is configured to seal only against an inner wall of the associated hollow body
