Rod Cosmetic Feeder Spring Buffer Prevents Axial Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rod-shaped cosmetic material feeding containers cause damage to the cosmetic material and container due to repeated release and recovery of the screwing mechanism, leading to back-and-forth movement of the movable body and potential breakage or dropping of the cosmetic material.
Innovation Solution
A rod-shaped cosmetic material feeding container design featuring a tubular container with a movable body and a rotation stopper tube, where the screwing mechanism is designed to stop moving once a limit is reached, preventing further movement and minimizing impact on the cosmetic material, using a spring to absorb external forces and ensure secure engagement of the screw parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the screw part is designed to allow repeated release and recovery of screwing, then the container can be operated multiple times, but the movable body moves back and forth causing damage to the cosmetic material
Solution Approach 1:
The patent introduces a buffer member positioned between the movable body and the cosmetic material. This buffer member absorbs and cushions the impact forces generated when the movable body moves back and forth during repeated operation, preventing direct transmission of harmful forces to the cosmetic material while allowing continued operation
2Ease of operation
If the movable body is allowed to move freely in axial direction, then the screw mechanism can be released, but the cosmetic material may break off or drop
Solution Approach 1:
The buffer member is pre-positioned to cushion the movable body's movement, preventing it from moving too far in either direction. This cushioning action maintains cosmetic material integrity while still allowing the screw mechanism to release and be operated
Solution Approach 2:
The buffer member acts as an intermediary element between the movable body and the cosmetic material. It mediates the interaction by absorbing excess movement forces, allowing the screw mechanism to release freely while protecting the cosmetic material from damage
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 design effectively protects the rod-shaped cosmetic material from damage by preventing back-and-forth movement and absorbing external forces, thus ensuring the material's integrity and minimizing container damage.
Implementation Method 1
the rotation stopper tube includes a spring portion expandable and contractible in the axial direction... the spring portion absorbs an external force applied to the rod-shaped cosmetic material by the elastic force of the spring portion
Implementation Method 2
The female screw is screwed with the male screw. The relative rotation of the front container part and the rear container part works a screw part constituted of the male screw and the female screw to advance and retreat the movable body

AI summary
A rod-shaped cosmetic material feeding container in which a leading tube and a container main body are relatively rotated in one direction, an action of a screw part moves a rod-shaped cosmetic material supporting body to reach a movement limit, and then the leading tube and the container main body are further relatively rotated in the one direction. With movement of the rod-shaped cosmetic material supporting body stopped, while a spring portion in a rotation stopper tube shrinks, the screw part screws forward to release screwing of the screw part. Additionally, the movement of the rod-shaped cosmetic material supporting body is stopped and therefore the rod-shaped cosmetic material supporting body does not move back and forth in an axial direction. Accordingly, a rod-shaped cosmetic material does not move back and forth in the axial direction as well, thereby ensuring minimizing an impact to the rod-shaped cosmetic material.
