Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a cosmetic container with a simplified configuration that is easy to manufacture and use, capable of reliable powder discharge and blocking to prevent leakage, while minimizing clogging and ensuring effective powder supply.
Innovation Solution
The cosmetic container features a container body with a brush part and an air injection part, an opening/closing mechanism with a housing, rotational body, and sleeve that allows selective communication of discharge and transfer holes, along with a sealing mechanism to prevent powder leakage, and an air injection system using a check valve to forcibly inject air and powder into the brush.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional opening/closing device is used, then powder discharge and blocking functions are achieved, but the configuration becomes complex and manufacturing becomes difficult
Solution Approach 1:
The patent combines the opening/closing mechanism with the powder discharge mechanism into a single integrated structure. The pressing member simultaneously performs the function of pressing the powder and controlling the opening/closing of the discharge hole, eliminating the need for separate mechanisms and simplifying the overall configuration while maintaining reliable powder discharge and blocking functions.
2Ease of manufacture
If the configuration is simplified, then manufacturing becomes easier, but powder discharge and blocking reliability may be compromised
Solution Approach 1:
The pressing member is designed as a multi-functional component that simultaneously performs powder pressing, discharge hole opening/closing control, and powder supply to the brush. This universal component approach reduces the number of parts needed for manufacturing while ensuring reliable powder discharge and blocking through its integrated design.
3Productivity
If powder is continuously supplied to the brush, then effective powder delivery is maintained, but powder leakage may occur when not in use
Solution Approach 1:
The discharge hole is designed to be dynamically controllable through the opening/closing mechanism. The hole remains closed during storage to prevent powder leakage, and opens only when the pressing member is actuated during use. This dynamic control allows continuous powder supply efficiency when needed while preventing harmful powder leakage when the container is not in use.
