Magnetic Hook Lock-Release Mechanism for Easy Load Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the shipbuilding industry, there is a need for a temporary suspension system that can easily and safely support loads like cables and pipes on smooth vertical surfaces without obstructing passage, as existing magnetic systems require high attractive forces, making installation and removal difficult and time-consuming.
Innovation Solution
A magnetic hook system with a locking-release mechanism using neodymium magnets and a polymeric material body, where the magnetic support is movable between retracted and extended positions, allowing easy installation and removal by leveraging a pin mechanism for manual detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If high attractive force magnets are used to support loads on vertical surfaces, then the load support capacity is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The magnetic support is made movable between retracted and extended positions, allowing the magnetic force to be dynamically adjusted. During installation/removal, the support retracts to minimize attraction; during operation, it extends to maximize load support capability.
Solution Approach 2:
The system separates the magnetic support function from the hook function, with the magnetic support being a distinct movable component that can be independently controlled to retract from or extend toward the ferromagnetic surface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system supports loads of 25 to 50 kg efficiently and quickly, facilitating temporary installations on ferromagnetic surfaces with reduced magnetic force requirements, enhancing operational efficiency and safety by allowing easy installation and removal without excessive manual effort.
Implementation Method 1
the attractive force of the magnets develops perpendicularly to the surface
Implementation Method 2
a thin layer of material is interposed with a high coefficient of friction (rubber or other), which, while causing the attractive power of the magnet to decline slightly, manages to create a good coefficient of friction between the magnet itself and the ferrous surface

AI summary
The present invention relates to a suspension system, in particular a magnetic hook, for loads, such as cables, pipes or other equipment provided with a locking-release system, facilitating the temporary use thereof on ferromagnetic surfaces, in particular for shipbuilding. In particular, the invention relates to a suspension system (1) characterized in that it comprises a fixed body (2) having a flat main face (2a), a magnetic support (3) associated with said fixed body (2) and a hook (4), in which the magnetic support (3) is movable along a direction perpendicular to the flat main face (2a) of the fixed body (2) between a retracted release position and an extended locking position, and in which the hook (4) is movable between a release position, in which the hook (4) is parallel to the main face (2a) of the fixed body (2), and a locking position, in which the hook (4) is perpendicular to the main face (2a) of the fixed body (2), and in which, in the release position, the hook (4) keeps the magnetic support (3) in the retracted position.
