Thrust-Out Container With Segmented Grooves For Compact Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thrust-out type containers for rod-like articles face challenges in minimizing their vertical dimension while maintaining the length by which the article can be thrust out, as increasing the thrust-out length necessitates an increase in the container's vertical height.
Innovation Solution
The container design features a driving cylinder with an outer and inner cylinder, a holder divided into upper and lower members, and a guide cylinder, allowing the groove distance to be divided, enabling the holder to move vertically without rotating, thus reducing the overall height while maintaining the thrust-out length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the groove length is increased to extend the thrust-out distance of the rod-like article, then the amount of article that can be thrust out is increased, but the vertical height of the container is inevitably increased
Solution Approach 1:
The single groove is divided into two separate grooves: a first groove formed on the outer cylinder and a second groove formed on the inner cylinder. The holder has a projection that engages with both grooves sequentially. This segmentation allows the total thrust-out distance to be achieved through the combined length of two shorter grooves, reducing the container's vertical height while maintaining the required thrust-out distance of the rod-like article.
2Length of stationary object
If the container height is minimized for design purposes, then the appearance is improved, but the thrust-out distance of the rod-like article is reduced
Solution Approach 1:
The invention introduces a radial dimension to the groove structure. The first groove extends radially inward from the outer cylinder's inner peripheral surface, and the second groove extends radially inward from the inner cylinder's inner peripheral surface. By utilizing the radial dimension, the grooves can provide the necessary thrust-out distance without requiring increased vertical height, thus minimizing container height while maintaining thrust-out distance.
3Device complexity
If a U-shaped notch is used as guide means, then the structure is simplified, but the structural rigidity is reduced and deformation may occur
Solution Approach 1:
The invention extracts and eliminates the U-shaped notch from the inner cylinder structure. Instead of forming a notch that compromises structural integrity, the guide means is implemented as a groove on the outer cylinder surface that engages with a projection on the holder. This removes the weak point (U-shaped notch) while maintaining the guiding function, thereby preserving structural rigidity and preventing deformation.

AI summary
A thrust-out type container for a rod-like article generally comprises a driving cylinder extending in a vertical direction, a cylindrical holder extending in the vertical direction inside the driving cylinder, and a guide cylinder adapted to restrict a movement of the holder so that the holder can not be non-rotatable with respect to the driving cylinder but movable in the vertical direction. The driving cylinder includes an outer cylinder formed on its inner peripheral surface with a first groove and an inner cylinder lying inside the outer cylinder and slidably engaged with the first groove so as to be movable in the vertical direction and formed on its inner peripheral surface with a second groove. An upper portion of the holder defined as a cup is configured so that the rod-like article can be attached thereto and a lower portion of the holder defined as a stem extending downward from the cup is adapted to be slidably engaged with the second groove of the inner cylinder.
