Elastic Screen Container with Variable Mesh Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic powder containers with elastic screens face difficulties in controlling the amount of contents extracted, as the uniform mesh density requires adjusting external force, leading to slow extraction and potential leakage, especially with smaller opening sizes.
Innovation Solution
A container with an elastic screen and a mesh adjustment mechanism that allows for variable mesh size adjustment using a moving member and a fixed member, where the mesh size can be adjusted by screwing a screen pressing member into a neck, enabling easier control of content extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mesh density is uniform over the entire screen surface, then the screen structure is simple and easy to manufacture, but it becomes difficult to control the amount of contents extracted and requires adjusting external pressing force
Solution Approach 1:
The patent applies the dynamics principle by making the mesh density adjustable rather than fixed. The screen's mesh density can be changed from uniform to non-uniform distribution according to user needs, allowing control over content extraction rate without changing the basic screen structure. This enables the screen to adapt between simple uniform configuration for easy manufacturing and controlled non-uniform configuration for operational flexibility.
Solution Approach 2:
The patent implements parameter changes by varying the mesh density parameter across different regions of the screen. Instead of maintaining constant mesh density, the screen is designed with regions of different mesh densities (coarse, medium, fine) that can be selectively used to control extraction rate, thereby solving the operational control issue while maintaining manufacturing simplicity.
2Ease of operation
If the mesh density changes continuously from coarse to fine on the screen, then the amount of contents extracted can be controlled by changing extraction position, but it becomes difficult to extract sufficient contents quickly and contents may leak from other areas
Solution Approach 1:
The patent applies segmentation by dividing the screen into distinct regions with different mesh densities (coarse mesh region, medium mesh region, fine mesh region). This allows users to select specific regions for extraction based on desired extraction rate, enabling both controlled extraction and high-speed extraction by choosing appropriate regions, thus resolving the contradiction between control and speed.
Solution Approach 2:
The patent implements local quality by giving different parts of the screen different mesh density characteristics. The coarse mesh region allows fast extraction, the fine mesh region provides precise control, and the medium mesh region offers intermediate options. This local differentiation enables users to optimize extraction speed and control based on specific needs without compromising either aspect.
3Area of stationary object
If the opening area of the container is reduced, then the container size is compact, but the problem of difficult content extraction and potential leakage becomes more pronounced
Solution Approach 1:
The patent applies local quality by concentrating different mesh density zones within the limited opening area. Even though the overall opening is small, the screen provides localized regions of coarse, medium, and fine mesh densities, allowing efficient extraction despite the compact size. This enables the container to maintain small dimensions while preserving extraction effectiveness through strategic mesh distribution.

AI summary
A container with elastic screen has a container body with an opening therein for extracting the contents; an outer lid that seals the opening, detachably attachable to the container body; a screen made of elastic mesh material, disposed so as to cover the opening; and a mesh adjustment mechanism for adjusting a mesh size of the screen. The mesh adjustment mechanism includes a moving member and a fixed member. With a normal direction to the plane in which the screen is stretched as the vertical direction, the moving member has a portion that contacts in a ring shape the peripheral edge of the top surface of the screen and makes the portion movable in the vertical direction with respect to the opening. The fixed member is fixed to the opening while fixing a vertical position of the moving member.
