Rotating Solid Cosmetic Dispenser for Precise Dose Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers for solid contents face issues such as the need for tools like tweezers for dispensing, potential damage to contents during handling, and difficulty in controlling the dispensing amount and color accuracy.
Innovation Solution
A container design featuring a housing, dispensing member, rotating member, and stopper member that allows for adjustable dispensing of solid contents without damaging others, using a rotating mechanism to control the dispensing amount and prevent color deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solid cosmetic materials are stored in conventional liquid cosmetic containers, then storage is simple, but tools like tweezers are required for dispensing and contents may be damaged during handling
Solution Approach 1:
The container is divided into an upper container body and a lower container body that can rotate relative to each other. The rotating member with through-holes segments the solid cosmetic contents, allowing individual pieces to be selectively dispensed without requiring external tools like tweezers.
Solution Approach 2:
The container introduces a dynamic rotating mechanism where the lower container body can rotate relative to the upper container body. This dynamic structure enables controlled dispensing of solid cosmetic materials by rotating the contents to desired positions, eliminating the need for static tool-based handling.
2Ease of operation
If tweezers are used to take out solid cosmetic materials, then dispensing is possible, but the tweezers may come into contact with other surrounding solid cosmetic materials causing crushing and breakage
Solution Approach 1:
The dispensing function is extracted from external tools (tweezers) and integrated into the container structure itself. The rotating member with through-holes allows solid cosmetic materials to be directly dispensed through the container wall without external tool intervention, eliminating the harmful contact between tweezers and other contents.
Solution Approach 2:
The rotating member acts as an intermediary between the stored solid cosmetic materials and the dispensing opening. It enables controlled transfer of individual pieces through its through-holes without requiring direct manual handling with tweezers that could damage surrounding contents.
3Ease of operation
If solid cosmetic materials are dispensed by hand, then no tools are needed, but other surrounding solid cosmetic materials may come into contact with fingers resulting in crushing and breakage
Solution Approach 1:
The rotating member with through-holes serves as an intermediary mechanism between the user's hand and the solid cosmetic materials. It allows finger operation to rotate the container and dispense contents through the opening while preventing direct finger contact with the cosmetic pieces, thus avoiding crushing and breakage.
4Device complexity
If conventional liquid cosmetic containers are used, then storage is simple, but the dispensing amount is not precisely controlled and color deviation occurs
Solution Approach 1:
The container segments the solid cosmetic materials into individual pieces that can be counted and dispensed one at a time through the rotating member's through-holes. This segmentation enables precise control over the dispensing amount, ensuring consistent dosage and preventing color deviation that occurs with uncontrolled liquid dispensing.

AI summary
A container for dispensing solid contents is disclosed. The container includes: a housing configured to store a plurality of solid contents having a predetermined shape; a dispensing member having a dispensing opening from which the solid contents are dispensed; and a rotating member provided on the upper side of the dispensing member to allow relative rotation with the dispensing member and configured to move at least some of the plurality of solid contents to the dispensing opening.
