Cosmetic Container Disc Valve Reduces Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers face issues with the scattering of powdered cosmetics and the thickness constraint due to the placement of check valves and support structures, which hinder the compact design and uniform discharge of liquid or gel cosmetics.
Innovation Solution
A cosmetic container design featuring a disc valve structure outside the piston assembly's moving region, a through-hole in the piston flange for reduced resistance, and a flap valve with increased contact area for improved closure and discharge efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the check valve and support structure are positioned directly below the flange of the piston, then the discharge function is achieved, but the thickness of the cosmetic container increases and compact design is hindered
Solution Approach 1:
The check valve is repositioned from a vertical arrangement (directly below the piston flange) to a horizontal arrangement (at the lower end of the center sleeve). This spatial reconfiguration in another dimension eliminates the need for additional vertical thickness while maintaining the discharge function, directly resolving the contradiction between functional effectiveness and compact dimensions.
2Productivity
If the lifting member is pressed downward by a predetermined stroke to discharge cosmetic solution, then the cosmetic solution is discharged, but the piston and flange movement creates interference with the check valve support structure
Solution Approach 1:
The check valve is extracted from its traditional position within the piston assembly's movement path and relocated to the lower end of the center sleeve. This separation removes the interference problem between the moving piston/flange components and the check valve support structure, allowing smooth operation during the discharge stroke without mechanical conflict.
3Reliability
If the cosmetic container is designed with sufficient thickness to accommodate the check valve support structure, then the check valve functions properly, but the overall container size increases and compactness is reduced
Solution Approach 1:
The check valve assembly is repositioned from a vertical configuration requiring increased container thickness to a horizontal configuration at the lower end of the center sleeve. This dimensional change allows the check valve to function reliably without increasing the overall container volume, achieving compactness while maintaining reliability.
