Slide Lipstick Case Button Guide Friction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lipstick containers have complex structures that increase production costs and require many components, leading to decreased productivity and inconvenient use, especially when trying to apply makeup outdoors with one hand.
Innovation Solution
A slide-type lipstick container with a button and button guide slit on the external case, a slide member coupled to the button and lipstick holder, and friction protrusions on the button ribs to control vertical movement, preventing the lipstick from being pushed down and allowing smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional lipstick container uses a rotary tube with spiral groove and guide groove structure to convert rotational movement into linear movement, then the lipstick can be moved up, but the structure becomes complex and requires many components
Solution Approach 1:
The patent extracts and eliminates the complex rotary tube with spiral groove and guide groove structure from the conventional lipstick container. By removing this complex mechanism, the invention simplifies the overall structure while maintaining the essential function of moving the lipstick up and down through a more straightforward design.
Solution Approach 2:
Instead of using a rotary tube that converts rotational movement into linear movement, the patent inverts the approach by using a simple push-button mechanism that directly translates downward pressure into upward movement of the lipstick. This inversion eliminates the need for complex mechanical conversion mechanisms.
2Ease of operation
If a conventional lipstick container uses a rotary tube and case body structure requiring two hands to operate, then the lipstick can be applied, but it becomes inconvenient for one-handed use when getting ready outdoors
Solution Approach 1:
The patent removes the two-handed rotary operation mechanism from the conventional lipstick container. By extracting the rotary tube and spiral groove structure, the invention creates a simplified push-button system that can be easily operated with one hand, making it convenient for outdoor use when getting ready.
3Productivity
If a conventional lipstick container uses a complex structure with many components, then the lipstick can be moved, but the production cost increases and productivity decreases
Solution Approach 1:
The patent merges multiple separate components into a simplified integrated structure. By combining the functions of the rotary tube, guide grooves, and movement mechanism into a simpler unified design, the invention reduces the total number of parts, lowers production costs, and enables faster assembly, thereby improving productivity.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from the conventional lipstick container structure. By removing the rotary tube, spiral groove, and multiple guide grooves, the invention significantly reduces the number of parts that need to be manufactured and assembled, directly improving production efficiency and reducing costs.
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 slide-type lipstick container simplifies the mechanism, reducing production costs and enabling convenient one-handed use by preventing the lipstick from being pushed down and allowing smooth up-and-down movement, enhancing user experience.
Implementation Method 1
friction protrusions are formed on the ribs of the button so that the friction protrusions make friction with the button guide slit to control the vertical movement of the button

AI summary
A slide type lipstick case prevents a cosmetic stick from sliding down when using the lipstick case, while maintaining soft sensitivity when operating the lipstick case, by: forming a button and a button guide slit into which the button is inserted on the outer peripheral surface of an outer case; connecting a slide member for moving the cosmetic stick upwards and downwards, to a rib of the button and the lower end of a cosmetic stick holder; forming control protrusions on the upper and lower side of the button guide slit; and forming friction protrusions, at the rib of the button, for interfering the upward and downward movements of the button by fractionizing button guide slit.
