Lipstick Packaging Machine Shock Protection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lipstick packaging machines fail to protect lipstick sticks during transport, as they are prone to damage from shocks and sudden movements, which is unacceptable for high-quality products intended for demanding clients.
Innovation Solution
A lipstick packaging machine design featuring a dual tubular body system with guides and a cursor mechanism, where the second tubular body has an annular groove and a flange that creates friction to prevent rotation during shocks, keeping the cursor stable and preventing contact between the lipstick tip and the closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging is used for lipstick machines, then the packaging is simple and easy to manufacture, but the lipstick stick is damaged during transport due to shocks and sudden movements
Solution Approach 1:
The packaging is divided into an outer packaging and an inner packaging, where the inner packaging contains the lipstick machine and provides shock absorption. This segmentation allows the outer packaging to be simple for shipping while the inner packaging provides specialized protection for the lipstick stick during transport.
Solution Approach 2:
Shock-absorbing materials are pre-installed within the inner packaging structure to cushion the lipstick machine before transport. This beforehand cushioning ensures that when shocks or sudden movements occur during shipping, the lipstick stick is already protected and prevented from contacting the closure.
2Reliability
If the cursor is allowed to move freely during transport, then the machine structure is simple, but the lipstick tip contacts the closure and gets damaged
Solution Approach 1:
The cursor stabilization mechanism applies preliminary counter-forces to prevent the cursor from moving toward the closure during transport. By anticipating potential shocks and applying opposing forces through the stabilization mechanism, the lipstick tip is prevented from contacting the closure even when external forces are applied.
Solution Approach 2:
The cursor stabilization mechanism acts as an intermediary between the cursor and the closure, preventing direct contact between the lipstick tip and closure. This mediator absorbs and distributes forces that would otherwise cause damage, allowing the cursor to move within controlled limits without compromising the lipstick tip.
3Object-affected harmful factors
If the packaging is designed to withstand major shocks, then the lipstick is protected during transport, but the packaging structure becomes more complex
Solution Approach 1:
The packaging uses a nested structure where the inner packaging containing the lipstick machine is placed within an outer packaging. This nested design allows the shock protection features to be concentrated in the inner packaging while the outer packaging remains relatively simple, achieving shock resistance without excessive overall complexity.
Solution Approach 2:
The packaging design changes physical parameters such as the density and distribution of shock-absorbing materials, the rigidity of packaging walls, and the cushioning characteristics to optimize protection against shocks. By carefully adjusting these parameters, effective shock resistance is achieved without unnecessarily increasing structural complexity.

AI summary
A lip stick machine includes a first tubular body on which a second tubular body is rotatably fitted, the first tubular body having at least one first guide and the second tubular body having at least one second guide, a cursor equipped with at least one first pin so that a mutual rotation of the first tubular body causes an axial translation of the cursor, a closure equipped with a tubular projection for coupling with a first free edge of the first tubular body when the closure is fitted on the machine; the second tubular body has a first annular groove open on a second free edge of the second tubular body, the first tubular body having a flange at the first free edge positioned inside the first annular groove so as to load a lateral surface of the annular groove when the closure is fitted on the machine.
