Magnetic Strap Hook With Sliding Magnet For Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic strap hooks tend to detach easily during the binding process due to the fixed magnet tilting and reduced attraction area when the binding strap swings, causing instability in attraction.
Innovation Solution
A magnetic strap hook design featuring a magnet holder with a slidably disposed magnet that can move back and forth or swing relative to the hook body, allowing the hook body to swing and extend/retract, thereby maintaining magnet attraction and preventing excessive motion that could lead to detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnet is fixed on the hook body, then the strap hook can be attracted by the vehicle body during the binding process, but the magnet tilts when the hook body tilts due to binding strap swinging, resulting in decreased attraction area and easy detachment
Solution Approach 1:
The magnet is designed to be movable relative to the hook body through a guide hole and limiting structure, allowing the magnet to dynamically adjust its position and orientation in response to binding strap swinging, thereby maintaining stable attraction to the vehicle body while accommodating hook body tilting
2Device complexity
If the magnet is fixed on the hook body, then the structure is simple, but the attraction area decreases when the hook body tilts during binding
Solution Approach 1:
The magnet can move within a guide hole and swing within a certain range, allowing the magnet to maintain its attraction area by adjusting its orientation independently of the hook body's tilting motion, thus preserving effective attraction area despite the added complexity of the guide hole and limiting structure
3Ease of manufacture
If the magnet is fixed on the hook body, then the manufacturing is simple, but the magnet falls off easily when the binding strap swings and causes hook body tilting
Solution Approach 1:
The magnet is positioned in a guide hole with a limiting structure that allows controlled movement and swinging, preventing the magnet from detaching while accommodating the dynamic forces generated by binding strap swinging, thus improving magnet retention without requiring complex fixed mounting mechanisms
Solution Approach 2:
The guide hole and limiting structure act as intermediary elements between the magnet and the hook body, providing a controlled interface that allows the magnet to maintain reliable connection to the vehicle body while accommodating movements caused by binding operations
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
This design enhances the stability of the strap hook's attraction by reducing the influence of swinging binding straps on the magnet's attraction efficiency and preventing tilting, ensuring a stable connection to the vehicle body.
Implementation Method 1
the magnet is attracted by the vehicle body to fix the strap hook

AI summary
The present invention provides a magnetic strap hook belonging to the technical field of logistics appliances. The present invention solves the problem that unhooking is easy to occur during usage of the magnetic strap hook in the prior art because the magnet is fixed on the hook body. The magnetic strap hook comprises a hook body, a magnet holder fixed on the hook body, and a magnet connected on the magnet holder. The hook body comprises a connector portion, and a hook portion connected to the connector portion and located at a front side of the connector portion. The magnet on the magnet holder is capable of moving back and forth relative to the hook body and/or swinging along front and rear directions of the hook body. The magnetic strap hook has the advantage of better stability of attraction of the strap hook during the process of binding goods.
