Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hooks for holding items on doors often require screws, which are not suitable for louvered, glass, or metal doors, and do not provide sufficient holding power for heavy items.
Innovation Solution
An article with an arc-shaped magnetic base, utilizing neodymium magnets, designed to attach to door hinges, offering a durable and screw-free solution for holding items of substantial weight, including decorative finishes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw-in hooks are used, then the hook can be securely attached to the door, but screws are not suitable for louvered, glass, or metal doors and may damage the door
Solution Approach 1:
The patent replaces the mechanical screw-in system with a magnetic attachment system. The magnetic base uses magnetic force to attach to the hinge, eliminating the need for screws and making it compatible with louvered, glass, and metal doors where screws cannot be used or would cause damage.
Solution Approach 2:
The magnetic base acts as an intermediary between the hook and the hinge. Instead of directly screwing into the door, the hook is attached to the magnetic base which then attaches to the hinge through magnetic force, providing a versatile attachment solution for various door types.
2Strength
If conventional hooks are used, then the installation is simple, but they do not provide sufficient holding power for heavy items
Solution Approach 1:
The patent uses a composite structure combining a magnetic base with high-powered magnets (such as neodymium magnets) and a hook component. This composite design provides substantial holding power (capable of holding over 30 pounds) while maintaining relative simplicity through the integration of these components into a single attachable unit.
3Reliability
If screws are used to attach hooks, then secure attachment is achieved, but damage to the door occurs
Solution Approach 1:
The patent replaces the mechanical screw-in system with a magnetic attachment system. The magnetic base uses magnetic force to attach to the hinge, eliminating the need for screws and making it compatible with louvered, glass, and metal doors where screws cannot be used or would cause damage.
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 magnetic article provides strong holding power, capable of supporting over 30 pounds of items, suitable for various door types and scenarios where screws are not allowed, offering additional hanging space without damaging the door.
Implementation Method 1
The article may have an arc profile which mates with the door hinge, although other profiles may be used. The article may include a hook or other article for holding items, including a hook for holding clothes, an elongated member for holding pants or other clothing, a spice rack or other articles. The article is capable of holding items of substantial weight due to the nature of the specific magnets, including neodymium magnets.
