Detachable Magnetic Holder With Cam Lever for Easy Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic holding devices lack efficient and easy detachment mechanisms, especially when high normal forces are applied, making it difficult to remove them from ferromagnetic surfaces.
Innovation Solution
A detachable magnetic holding device with a levering cover and cam mechanism that allows for controlled detachment by pivoting the lever cover relative to the body portion, minimizing the gap between the magnet and the surface to reduce normal force, and utilizing a compressible grip material to maximize holding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnetic holding device uses strong magnetic attraction to maintain secure attachment, then the holding force increases, but the detachment difficulty increases
Solution Approach 1:
The device employs a dynamic lever cover that can pivot between a closed position (maintaining strong magnetic attachment) and an open position (reducing magnetic force for easy detachment). The lever cover moves from covering the magnet to exposing it, dynamically changing the magnetic interaction state based on operational needs.
Solution Approach 2:
The lever cover acts as an intermediary element between the user and the magnetic force. By manipulating the lever cover, the user indirectly controls the magnetic attachment strength without directly interfering with the magnet itself, enabling smooth transitions between attached and detached states.
2Strength
If the device maintains minimal gap between magnet and surface for strong attachment, then the magnetic holding force increases, but the device complexity increases
Solution Approach 1:
The lever cover combines multiple functions into a single component: it serves as both a protective cover for the magnet and a mechanical lever for detachment. The cam portion of the lever cover integrates the detachment mechanism with the cover structure, eliminating the need for separate components and reducing overall device complexity.
Solution Approach 2:
The lever cover is designed as a multi-functional element that provides magnetic shielding, mechanical leverage for detachment, and structural support. The cam mechanism within the lever cover enables detachment functionality without requiring additional dedicated components, achieving universal functionality with minimal parts.

AI summary
A detachable magnetic device includes a body portion, a levering cover, a magnet-retaining portion, a magnet, and a grip material. The body portion defines a first surface, a second opposing surface, and a magnet-receiving opening. A cam portion of the levering cover is pivotally connected to an end of the body portion. The magnet-retaining portion extends across part of the first surface of the body portion. The magnet is coupled to the magnetic-retaining portion and disposed within the magnet-receiving opening. The grip material surrounds the magnet-receiving opening. The magnet is configured to magnetically couple the detachable magnetic device to a ferromagnetic object and the cam portion is configured to contact a surface of the ferromagnetic object when the levering cover rotated relative to the body portion to release the detachable magnetic device from the ferromagnetic object.
