Stick-Type Container Elevation Mechanism for Cosmetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stick-type containers face challenges such as complex structures, high manufacturing costs, difficult refilling processes, inability to use cosmetic material to the end, and lack of pressure adjustment functionality.
Innovation Solution
A stick-type container design featuring a contents holder, a body, an elevation member that ascends and descends to adjust exposure, and a holder support unit with an elastic support part, allowing for easy refilling and use of cosmetic material to the end without a separate tool, and providing cushioning to adjust pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate inner container with thread is placed in the container to move the external elevation member, then the elevation member can be moved, but the structure becomes complicated
Solution Approach 1:
The patent removes the separate inner container with thread from the structure. Instead, the elevation member is directly moved by rotating the outer container, which rotates a drive gear that engages with a rack on the elevation member. This extraction of the inner container simplifies the overall structure while maintaining the elevation adjustment function.
Solution Approach 2:
The patent combines the rotation function of the outer container with the drive mechanism for the elevation member. The outer container's rotation directly drives the elevation member through the gear-rack mechanism, merging what were previously separate functions (outer container rotation and elevation member movement) into a unified system.
2Stability of the object's composition
If guide tube, extension portion, and through-hole are formed in non-circular shape to prevent rotation, then the cosmetic material does not rotate, but the structure becomes complicated
Solution Approach 1:
The patent employs asymmetric (non-circular) cross-sections for the guide tube, extension portion, and through-hole. This asymmetric geometry prevents rotational movement of the cosmetic material and elevation member while maintaining a relatively simple overall structure. The non-circular shape provides the necessary constraint without requiring additional complex components.
3Adaptability or versatility
If the container is refilled with cosmetic material by holding it in hand, then refilling is possible, but the cosmetic material may get on hand or other objects and be lost or damaged
Solution Approach 1:
The patent introduces an intermediary mechanism for refilling. The cosmetic material is transferred using a refill tool or device that interfaces with the container's opening, rather than direct hand contact. This intermediary prevents the cosmetic material from contaminating the user's hands or surrounding objects while enabling the refilling function.
4Loss of substance
If a separate brush is used to use the remaining portion of lipstick to the end, then the cosmetic material can be used completely, but an additional tool is required
Solution Approach 1:
The patent designs the container and cosmetic material interface to enable direct usage of the remaining material. The elevation member and contents holder configuration allows the user to access and use the cosmetic material directly without requiring a separate brush tool. The system serves itself by providing adequate exposure and access to the material throughout its entire lifespan.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container allows for easy adjustment of exposure, facilitates refilling without hand contact, enables complete use of cosmetic material, and provides cushioning for precise pressure application, addressing the limitations of conventional designs.
Implementation Method 1
an elastic support part disposed in the hollow portion, located under the upper coupling portion to support the upper coupling portion, and configured to be elastically deformed by pressure applied to the upper coupling portion

AI summary
A stick-type container includes a contents holder to allow contents to be loaded therein, a body, an elevation member to ascend and descend to adjust exposure of the contents, and a holder support unit disposed in the body and to be detachably coupled to the contents holder to support the contents holder. The holder support unit includes a holder support body having a hollow portion, a cylindrical or polyhedral shape, and coupled to the body, a holder moving part disposed in the hollow portion and having an upper coupling portion detachably coupled to the contents holder, and an elastic support part disposed in the hollow portion and located under the upper coupling portion to support the upper coupling portion.
