Cosmetic Container Guard Ring Structure for Stable Smooth Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stick-type cosmetic containers face issues with maintaining an appropriate clearance between the guard ring and flange plate, leading to instability and reduced sensitivity of lifting and lowering due to injection molding deviations.
Innovation Solution
Incorporation of anti-rolling members, such as through holes, buffer platforms, buffer protrusions, or buffer bridges, to stabilize the guard ring by absorbing injection molding deviations and maintaining a consistent clearance with the flange plate, preventing shaking during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clearance between the lower end of the guard ring and the flange plate is wide, then the frame rotates smoothly, but the guard ring and lifting and lowering part shake and become unstable
Solution Approach 1:
The invention changes the physical state of the flange plate by introducing elastic deformation capability through anti-rolling members. The flange plate transitions from a rigid structure to one with controlled flexibility, allowing it to adapt the clearance dynamically between the guard ring and flange plate, thus resolving the contradiction between rotation smoothness and stability.
Solution Approach 2:
The invention makes the clearance between the guard ring and flange plate dynamic rather than fixed. The anti-rolling members enable the flange plate to deform elastically, adjusting the clearance automatically based on operational conditions, allowing smooth rotation while preventing excessive shaking.
2Stability of the object's composition
If the clearance between the lower end of the guard ring and the flange plate is narrow, then the lifting and lowering part becomes stable, but interference occurs between the guard ring and flange plate
Solution Approach 1:
The invention changes the physical state of the flange plate by introducing elastic deformation capability through anti-rolling members. The flange plate transitions from a rigid structure to one with controlled flexibility, allowing it to adapt the clearance dynamically between the guard ring and flange plate, thus resolving the contradiction between rotation smoothness and stability.
Solution Approach 2:
The invention makes the clearance between the guard ring and flange plate dynamic rather than fixed. The anti-rolling members enable the flange plate to deform elastically, adjusting the clearance automatically based on operational conditions, allowing smooth rotation while preventing excessive shaking.
3Productivity
If injection molding is used to manufacture the components, then production efficiency is high, but deviation in molding size occurs making consistent clearance difficult to maintain
Solution Approach 1:
The invention changes the physical state of the flange plate by introducing elastic deformation capability through anti-rolling members. The flange plate transitions from a rigid structure to one with controlled flexibility, allowing it to adapt the clearance dynamically between the guard ring and flange plate, thus resolving the contradiction between rotation smoothness and stability.
Solution Approach 2:
The invention converts the harmful effect of injection molding deviation into a beneficial feature. Instead of trying to eliminate the size variation, the design uses the anti-rolling members to absorb these variations through elastic deformation, transforming the manufacturing tolerance issue into a functional advantage that ensures consistent performance.

AI summary
A cosmetic container may include a lifting and lowering part configured to accommodate a cosmetic and having a guide protrusion disposed on an outside thereof, a guard ring having a spiral groove which is coupled to the guide protrusion and formed on an inner circumferential surface thereof, and a frame including a body coupled to an inside of the guard ring and in which a guide hole through which the guide protrusion of the lifting and lowering part passes is formed, a lower edge provided in a lower portion of the body, and a flange plate provided between the body and the lower edge to allow a lower end of the guard ring to be seated thereon, in which the cosmetic container further includes a plurality of anti-rolling members positioned near the flange plate and protruding toward the guard ring.
