Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fasteners for attaching objects to gypsum wallboard panels damage the surface when removed, requiring costly and time-consuming repair processes to restore the panel.
Innovation Solution
A magnetic fastener system embedded within the wallboard panel, using a neodymium body covered with wallboard joint tape and counter-sunk throughbore, which secures magnetized items without visible damage, and can engage studs or use anchor technology if none are present, ensuring secure attachment and easy removal without surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fasteners (nails or screws) are used to attach objects to wallboard panels, then secure attachment is achieved, but the panel surface is damaged when fasteners are removed
Solution Approach 1:
The patent replaces the mechanical fastening system (nails, screws) with a magnetic field-based attachment system. The magnetic fastener body generates magnetic force to hold objects against the wallboard panel without mechanical penetration, eliminating surface damage upon removal while maintaining secure attachment.
Solution Approach 2:
The magnetic fastener body acts as an intermediary between the wallboard panel and the object to be attached. It provides a non-invasive connection method where the magnetic field serves as the mediating force, allowing secure attachment without direct mechanical contact that would damage the panel surface.
2Object-affected harmful factors
If magnetic fasteners are embedded in wallboard panels, then objects can be attached and removed without surface damage, but the fastener structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into a single integrated magnetic fastener body: the magnetic attachment function, the structural support function, and the surface finishing function (via joint tape and compound) are combined in one component. This reduces overall system complexity despite the advanced functionality.
Solution Approach 2:
The magnetic fastener body is covered with wallboard joint tape and finished with joint compound to create a homogeneous appearance with the surrounding wallboard panel. This camouflaging approach makes the fastener indistinguishable from the panel surface, simplifying the visual complexity while maintaining functional complexity.
3Strength
If the fastener diameter is increased to handle larger objects, then load capacity is improved, but the visibility and potential damage risk to the panel surface increases
Solution Approach 1:
The patent utilizes parameter changes in the magnetic field strength and distribution within the fastener body to increase load capacity without proportionally increasing the fastener diameter. By optimizing magnetic material properties and field configuration, higher holding forces are achieved within compact dimensions.
Solution Approach 2:
The magnetic fastener body employs composite construction with magnetic materials (such as neodymium) combined with structural materials, allowing high magnetic field generation and load capacity within a small diameter. The composite structure maximizes magnetic performance while minimizing physical dimensions and panel surface impact.
