Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing dispenser containers for pressurized fluids are complex and costly, with challenges in achieving high dimensional accuracy and maintaining constant pressure over the lifetime of the dispenser.
Innovation Solution
A method involving a cylindrical shell with a partition wall and a piston, where the partition wall is fixed using an external indent that forms a protrusion inside the shell, ensuring a gastight connection and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the partition wall is fixed by deformation of the cylindrical metal shell to create an internal protrusion, then the partition wall can be secured in position, but the assembly becomes complex and manufacturing precision is difficult to achieve
Solution Approach 1:
The cylindrical shell is pre-formed with an external indent during the shell forming process, which creates a corresponding internal protrusion that serves as a positioning feature for the partition wall. This preliminary action eliminates the need for complex post-assembly operations to create the protrusion, thereby improving manufacturing precision while ensuring reliable partition wall fixation.
2Reliability
If the partition wall is fixed by deformation of the cylindrical metal shell, then the partition wall can be secured, but the manufacturing process becomes time-consuming and costly
Solution Approach 1:
The external indent is integrated into the cylindrical shell forming process itself, combining the shell formation and indent creation into a single manufacturing step. This merging of operations eliminates separate deformation steps that would otherwise be required to create the internal protrusion, thereby reducing manufacturing time and cost while ensuring reliable partition wall fixation.
3Reliability
If the partition wall must fit gastight to the inner wall of the cylindrical shell, then pressure control is maintained, but the assembly complexity increases and dimensional accuracy becomes more difficult to achieve
Solution Approach 1:
The external indent is pre-formed on the cylindrical shell, creating a corresponding internal protrusion that serves as both a positioning feature and a sealing surface for the partition wall. This preliminary action ensures that the partition wall automatically achieves gastight connection upon insertion, without requiring complex assembly operations or specialized sealing components, thereby maintaining pressure control while simplifying assembly.
