Lipstick Vessel Guide Member and Packing Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lipstick vessels allow outside air to enter when not in use, leading to lipstick deterioration due to improper positioning of the lipstick during transportation.
Innovation Solution
A lipstick vessel design featuring a cylindrical upper cover, shoulder, lower cover, rotating body, lipstick holding member, guide member, and packing member that prevents air entry by using a belt-shaped packing member and tapered guide structures to ensure the lipstick is centered and protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lipstick vessel is rotatably coupled to the main body for lifting and lowering the lipstick, then the ease of operation is improved, but the reliability deteriorates because the lipstick may be improperly positioned during transportation due to external impact
Solution Approach 1:
The guide member is pre-installed between the rotating body and lipstick holding member to establish vertical movement constraints before transportation occurs. This preliminary structural arrangement ensures that during external impact, the lipstick holding member can only move vertically along the guide member's tapered outer circumference, preventing improper positioning while maintaining the rotatable coupling mechanism for ease of operation
Solution Approach 2:
The guide member acts as an intermediary component between the rotating body and lipstick holding member. Its tapered outer circumference provides a guiding surface that mediates the interaction between these components, ensuring vertical movement during transportation while allowing rotational operation during use, thus resolving the contradiction between reliability and ease of operation
2Ease of operation
If the lipstick holding member is freely movable in the rotating body, then the ease of operation is improved, but the manufacturing precision deteriorates because the lipstick cannot be correctly positioned in the center
Solution Approach 1:
The guide member serves as an intermediary that provides a tapered outer circumference guiding surface. This structure mediates the positioning between the rotating body and lipstick holding member, ensuring the lipstick is correctly positioned in the center during manufacturing while still allowing free vertical movement for ease of operation during use
3Ease of operation
If the upper cover is opened to allow access to the lipstick, then the ease of operation is improved, but the reliability deteriorates because outside air can enter and cause lipstick deterioration
Solution Approach 1:
The packing member in belt shape acts as a flexible sealing element that can be compressed between the upper cover and rotating body. This flexible sealing structure allows the upper cover to be opened for ease of operation while preventing outside air from entering when closed, thus maintaining lipstick quality and reliability

AI summary
A lipstick vessel includes: a cylindrical upper cover, the upper part of which is closed and the lower part thereof is opened; a shoulder of a cylindrical member, the upper and lower parts of which are opened, which is inserted into the lower opening of the upper cover; a lower cover of a cylindrical member, the upper part of which is opened and the lower part thereof is closed, and the upper opening portion thereof is inserted into the lower outer circumference of a circumferential protrusion protruding outward at a center of the shoulder; a rotating body of a cylindrical member, which is inserted into the lower cover to rotate integrally with the lower cover; and a lipstick holding member for holding a lipstick at the upper part thereof.
