Two-Step Lift Mechanism for Stick Cosmetic Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for stick-type cosmetics often leave residues due to difficulties in completely exposing and using the content, as the height of the supporting plate restricts full access.
Innovation Solution
A container with a two-step lift structure, featuring a first lifting portion and a second lifting portion that move synchronously or independently to ensure complete exposure and use of the content, minimizing residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single plate structure is used to support stick-type cosmetics, then the structure is simple, but the content cannot be completely exposed and residues are left
Solution Approach 1:
The single plate structure is divided into two separate lifting portions: a first lifting portion that raises the content to a first height, and a second lifting portion that raises the content further to a second height. This segmentation allows complete exposure of the content in two stages, solving the problem of residues while maintaining reasonable structural complexity through modular design.
2Loss of substance
If a two-step lift structure is implemented, then complete use of content is achieved, but the device complexity increases
Solution Approach 1:
The second lifting portion is disposed inside the first lifting portion, creating a nested configuration. The second lifting portion can move independently within the space provided by the first lifting portion. This nesting approach minimizes the overall device volume and reduces structural complexity while enabling the two-step lifting function to eliminate content residues.
3Length of stationary object
If the plate height is increased to expose more content, then more content can be accessed, but the structure becomes less stable and control is difficult
Solution Approach 1:
Instead of using a single static plate of fixed height, the invention employs two dynamic lifting portions that can move independently to different heights. The first lifting portion raises the content to an intermediate height, and the second lifting portion provides additional elevation. This dynamic, multi-stage approach maintains structural stability while achieving complete content exposure, avoiding the instability associated with a single tall plate.

AI summary
A container for stick type content includes a housing, a manipulation portion coupled to a lower side of the housing to be relatively rotatable with the housing, a first lifting portion provided inside the housing and including an accommodation portion on top in which at least a part of content is accommodated, and a second lifting portion provided inside the first lifting portion and including a support portion disposed inside the accommodation portion to support the content from below. The first lifting portion and the second lifting portion move upward or downward according to rotation of the manipulation portion, and the first lifting portion and the second lifting portion move upward simultaneously and move the content upward when the manipulation portion rotates in one direction while the second lifting portion moves upward alone and moves the content further upward when the first lifting portion moves upward to a certain height.
