Side Button Lipstick Container with Elastic Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lipstick containers have complex structures that decrease productivity and are inconvenient for use, especially for women with weaker strength, due to their complicated mechanisms and potential for the cap to be easily lost or difficult to open.
Innovation Solution
A stick-type cosmetic material container with a side button that features a moving member inside the container cap, an elastic member, and a fixing member, allowing the container body to be easily pulled out by pressing the side button, which simplifies the assembly and use by releasing the fastening state between the moving and operating members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the over-cap is weakly fastened with the case, then it is easy to separate and open, but the over-cap may be easily separated and lost while being carried
Solution Approach 1:
The patent employs a dynamic fastening system where the operating member can transition between a fastening state (holding the container body in place during carrying) and a non-fastening state (allowing easy removal when needed). The elastic member enables the fastening member to automatically engage and disengage based on applied force, providing both security during transport and ease of access during use.
2Reliability
If the over-cap is strongly fastened with the case, then the cap retention is secure, but it is inconvenient to use because women who are relatively weak in strength may not easily separate the over-cap from the case
Solution Approach 1:
The patent introduces an intermediate mechanism consisting of the operating member, elastic member, and fastening member that mediates between the user's input force and the fastening force. This intermediary system amplifies the user's input through the elastic member's stored energy, allowing even users with weak strength to easily activate the fastening and release mechanisms.
Solution Approach 2:
The fastening system transitions from a static strong fastening to a dynamic system where the elastic member stores and releases energy. The elastic member accumulates elastic force during compression and automatically releases it to engage or disengage the fastening member, making the operation easy regardless of user strength.
3Reliability
If a conventional one-touch structure is used with linear motion operating tube and spring, then the container cap is prevented from separating, but the structure becomes complicated and productivity decreases
Solution Approach 1:
The patent divides the fastening function into distinct modular components: the operating member for user input, the elastic member for force storage, and the fastening member for engagement. This segmentation allows each component to be independently manufactured and assembled, simplifying the overall assembly process and improving productivity while maintaining reliable cap retention.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components from conventional designs. By directly connecting the operating member to the fastening member through the elastic member, the design removes redundant parts and complex mechanisms, resulting in a simpler structure that is easier to manufacture and assemble.
4Reliability
If a complex mechanism with multiple components is used, then the cap can be securely fastened, but the device complexity increases and ease of manufacture decreases
Solution Approach 1:
The patent merges multiple functions into a compact integrated system where the operating member, elastic member, and fastening member work together as a unified mechanism. This consolidation reduces the total number of separate components and simplifies the assembly process while maintaining secure fastening functionality.
Solution Approach 2:
The operating member serves multiple functions: it compresses the elastic member to store energy, directly transmits force to the fastening member for engagement, and can be used to trigger release. This multi-functionality reduces the need for separate components and simplifies the overall manufacturing process.

AI summary
A container having: a container body having a stick-type cosmetic material embedded therein; a container cap for opening/closing the container body; a side button provided on a side surface of the container cap; a moving member elastically moving up and down by means of an elastic member on the inside of the container cap, and having a fastening part formed therein; a fixing member for restricting the separation of the moving member from the container cap; and an operating member fastened to or unfastened from the fastening part of the moving member by elastically moving back and forth by means of the button, thereby having a structure in which the fastening of the operating member and the moving member is released so as make the container body, which is inserted into the moving member while the moving member is elastically moved to the lower side.
