Paper Lipstick Tube Threaded Push-Pull Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lipstick tubes made of metal or plastic materials are costly to produce and not environmentally friendly due to their complex manufacturing processes and non-biodegradable materials, leading to increased preparation costs and environmental waste.
Innovation Solution
A paper lipstick tube with threads is designed, comprising a lipstick tube body made of paper and natural bamboo/wood materials, featuring a pin that applies upward and downward shearing forces through a threaded groove and guide openings to enable a push-pull function without rotation, reducing production costs and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional metal or plastic molding technologies are used to process threads and guide rails, then the push-pull function is achieved, but the preparation cost increases
Solution Approach 1:
The patent changes the material parameter from traditional metal/plastic to paper material, and changes the structural parameter by using a pin passing through guide openings and threaded grooves instead of traditional molding. This allows the push-pull function to be achieved through the interaction between the pin and the threaded grooves in the paper tubes, reducing preparation cost while maintaining functionality
Solution Approach 2:
The pin serves as an intermediary element that mediates between the threaded grooves in the B lipstick tubing and the guide openings in the D lipstick tubing. This intermediary component enables the push-pull function by translating rotational motion into linear motion through its interaction with the threaded grooves, achieving the desired function without complex molding
2Object-affected harmful factors
If traditional metal or plastic materials are used, then structural strength is ensured, but environmental friendliness deteriorates
Solution Approach 1:
The patent uses composite construction by combining multiple paper tubes (A, B, C, D, F, M, K lipstick tubings) with different functions, along with a pin and circular gasket. This composite structure of biodegradable paper materials achieves the required structural strength while being environmentally friendly and biodegradable, eliminating the harmful effects of traditional metal and plastic materials

AI summary
A paper lipstick tube with threads, including a lipstick tube body which includes an A lipstick tubing, a B lipstick tubing, a C lipstick tubing, a pin, a D lipstick tubing, an F lipstick tubing, an M lipstick tubing, a K lipstick tubing, a cover tube H, a circular gasket and cream. The B lipstick tubing is rotatably installed inside the F lipstick tubing. The lipstick tube body is a container with a push-pull function made of only paper and a small amount of natural bamboo or wood materials. Through mutual rotation of the F lipstick tubing and the B lipstick tubing, upward and downward shearing forces are applied to the pin spirally through the threaded groove in the B lipstick tubing. At the same time, the pin is also in up-and-down guide openings of the D lipstick tubing, so that the C lipstick tubing can only move up and down.
