Magnet-Retained Fluid Application Head with Rotating Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid application devices, such as those with a ball-shaped application head retained by a magnet, have a limited application surface and difficulty in removal due to a small protruding surface area and poor graspability.
Innovation Solution
A fluid application device with a holder containing a magnet and a magnetizable application head that is rotatably movable, providing a larger application surface greater than half of the total outer surface, allowing easy removal and improved rotation for better usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application head is retained by a magnet in a recess, then the application head is securely held, but the application surface becomes limited and difficult to grasp for removal
Solution Approach 1:
The application head is designed with a diameter larger than the cavity depth, creating a protruding portion that extends beyond the holder surface. This dimensional change allows the application surface to exceed half the total outer surface of the head, simultaneously maintaining magnetic retention while providing sufficient graspable area for easy removal.
2Force
If the application head protrudes minimally from the holder, then the magnetic retention is strong, but the rotation of the application head is limited
Solution Approach 1:
The application head is designed to be rotatably movable within the cavity, transitioning from a fixed position to a dynamic rotating motion. The protruding design with sufficient overhang from the holder allows the head to rotate freely while maintaining magnetic attraction, enabling users to easily access and manipulate the application surface.
3Reliability
If the application head has a small protruding surface, then the magnetic retention is effective, but the ease of grasping and removal becomes difficult
Solution Approach 1:
By designing the application head with a diameter larger than the cavity depth, the head protrudes sufficiently from the holder to provide a grasping surface area greater than half of its total outer surface. This dimensional configuration allows users to easily grasp and remove the head while the magnet continues to provide effective retention when the head is in its proper position.
Applied Scientific Principles

AI summary
A fluid application device and a device for storing and dispensing a fluid, as a massage device, includes: a holder including a cavity that has a visible depth for the cavity; at least one magnet contained within a recess that is present in the holder; and an application head including at least one portion made of a magnetizable material that is formed so as to be attracted by the magnet(s). The application head has an application surface higher than half the total outer surface of the application head, the device being arranged such that the application head is rotatably movable within the cavity.
