Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic connection systems in perfumery and cosmetics dispensers require abrupt gestures to overcome maximum magnetic attraction, leading to potential fluid leakage and an unsatisfactory user experience due to the need for strong axial pull forces.
Innovation Solution
Incorporating a mechanical cam mechanism that transforms rotational movement into axial displacement, allowing the removable member to be detached from the base part without a direct axial pull, thereby reducing magnetic attraction and facilitating easy removal and repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If powerful magnetic means are implemented to guarantee a good connection, then the connection stability is improved, but the removal operation becomes difficult requiring considerable axial pull force
Solution Approach 1:
The patent transforms the removal operation from axial dimension to rotational dimension. Instead of pulling the cap axially to overcome magnetic attraction, the user rotates the cap around the reservoir neck. The cam mechanism converts this rotational movement into axial displacement, allowing the cap to be removed without directly opposing the strong axial magnetic force.
2Ease of operation
If weak magnetic means are implemented to facilitate easy removal, then the removal operation becomes easier, but the connection stability deteriorates
Solution Approach 1:
The patent introduces a cam mechanism as an intermediary between the user's rotational action and the cap's axial movement. This cam mechanism acts as a mechanical mediator that translates rotational motion into axial displacement, enabling cap removal without requiring the user to directly overcome the magnetic attraction force.
3Ease of operation
If direct axial pull is used to remove the cap, then the removal action is simple, but fluid leakage and product loss occur due to abrupt tearing
Solution Approach 1:
The patent changes the removal operation from axial to rotational dimension. By rotating the cap instead of pulling it axially, the separation occurs gradually through the cam mechanism's axial displacement, preventing abrupt tearing that would cause fluid leakage and product loss.

AI summary
Device comprising a base part (1) and a removable member (3) mounted removably on the base part (1), the base part (1) and the removable member (3) comprising magnetic means (15, 35) that are able to generate axial magnetic attraction between one another which is at a maximum in an assembled rest position, characterized in that it also comprises movement means (4), separate from the removable member (3), for axially moving the removable member (3) away from the base part (1), starting from the assembled rest position, by rotation of an actuating member (7) that is part of the movement means (4), in order to reduce the magnetic attraction between the base part (1) and the removable member (3) and thus to make it easier to remove the removable member (3).
