Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers face issues with residual contents and difficulty in adjusting discharge quantity, particularly with gel-type cosmetics that stick to puffs and are not efficiently used due to gravity and adhesion problems.
Innovation Solution
A cosmetic container equipped with a rubber discharge pad having multiple outlets that can be pressed to adjust discharge quantity, coupled with a tension cap to prevent separation and ensure efficient use of contents without residuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gel-type contents are impregnated into an impregnation member for use, then the contents can be applied to a puff, but the contents gradually move to an upper portion due to gravity and the contents in the lower portion cannot be used
Solution Approach 1:
The patent inverts the traditional impregnation member structure by placing multiple outlets at the bottom instead of having a single top opening. This allows gravity to work in favor of discharge by enabling contents to flow downward through multiple outlets, ensuring complete utilization of contents without residual material remaining in the lower portion.
Solution Approach 2:
The impregnation member is segmented into multiple outlets distributed across its bottom surface rather than having a single discharge point. This segmentation allows contents to be discharged through multiple pathways simultaneously, improving flow efficiency and ensuring complete emptying of the container while maintaining ease of application to the puff.
2Device complexity
If a single outlet is used in the discharge pad, then the structure is simple, but the discharge quantity cannot be adjusted
Solution Approach 1:
The discharge pad incorporates multiple outlets that can be dynamically controlled through pressing action. When the user presses the discharge pad, the outlets open to allow contents to flow; when released, the outlets close. This dynamic mechanism enables adjustable discharge quantity based on pressing force and duration, providing versatility without complex additional components.
Solution Approach 2:
The single outlet is segmented into multiple outlets across the discharge pad surface. This segmentation provides inherent adjustability - users can control the effective discharge area by varying pressing force, and the multiple outlets allow for distributed flow that can be modulated to achieve different discharge quantities without adding mechanical complexity.
3Loss of substance
If the rubber discharge pad is pressed hard to discharge all contents, then residual contents are eliminated, but the outlets may expand too much causing uncontrolled discharge
Solution Approach 1:
The discharge pad uses multiple small outlets distributed across its surface rather than a single large outlet. This segmentation provides several benefits: it distributes the discharge flow across multiple points, preventing uncontrolled gushing even when pressed; it allows gradual emptying as each outlet operates independently; and it maintains better control over discharge rate while ensuring complete utilization of contents.
Solution Approach 2:
The discharge pad structure incorporates outlets with specific local properties - they are designed to expand controllably under pressure. The local quality of each outlet is optimized to allow sufficient opening for complete discharge while maintaining enough structural integrity to prevent excessive expansion and uncontrolled flow, balancing residual elimination with discharge control.

AI summary
The present invention relates to a cosmetic container provided with a rubber discharge pad, in which: a rubber discharge pad having a plurality of discharge ports is coupled to a container body, and when the rubber discharge pad is pressed, the rubber discharge pad is pressed to the bottom of the container body by elasticity such that the content accommodated in the container body is capable of being used without residual content; and since the content accommodated in the container body is discharged through the discharge ports of the rubber discharge pad, the expansion size of the discharge ports varies according to a force of pressing the discharge pad such that a discharge quantity of the content can be adjusted.
