Flexible Permeable Housing for Controlled Powder Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers lack control over powder flow, resulting in unnecessary waste as too much powder is dispensed during application.
Innovation Solution
A powder dispensing device with a flexible powder dispensing housing made from permeable materials like cloth, sponge, or fur, and an ergonomic handle with a hook, allowing precise control over powder release through a detachable lid and apertures in the bottom wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional cosmetic container with penetrating holes and through holes is used, then powder can flow out from the container body, but powder flow rate is not controlled and unnecessary powder flows out causing waste
Solution Approach 1:
The housing is made from a flexible material that allows it to be compressed by pressing the handle. This dynamic compression controls the powder flow rate through the permeable housing, allowing users to dispense powder at a controlled rate rather than having uncontrolled flow through fixed holes.
Solution Approach 2:
The flexible housing material changes its permeability parameters when compressed. By pressing the handle, the housing compression alters the flow characteristics of powder through the material, enabling controlled dispensing. The degree of compression directly controls the powder flow rate.
2Ease of operation
If the housing is made from a flexible permeable material, then powder flow can be controlled through compression, but the device structure becomes more complex
Solution Approach 1:
The housing combines multiple functions into a single component: it serves as both the powder delivery mechanism and the flow control mechanism. The flexible permeable material integrates the dispensing function with the compression control function, eliminating the need for separate valves or flow control mechanisms.
Solution Approach 2:
The housing is constructed from a flexible permeable material that allows controlled powder passage. This flexible shell structure enables flow control through compression while maintaining a simple single-piece design, avoiding complex mechanical flow control systems.
3Productivity
If apertures are added to the bottom wall to connect cavity with housing, then powder can be dispensed more efficiently, but the sealing requirement becomes more difficult to maintain
Solution Approach 1:
The seal between the cavity and housing changes from a static密封 to a dynamic seal that adapts during compression. As the flexible housing is compressed, the sealing interface parameters change to maintain effective sealing while allowing controlled powder flow through the apertures.
