Rotatable Piercing-Member Fastener for Repeatable Fabric Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for attaching objects to surfaces are either cumbersome, costly, or damage the material, and lack a simple and versatile mechanism for frequent and efficient attachment and detachment.
Innovation Solution
A fastening device with a rotatable base and an open-ring shaped piercing member that follows a curved trajectory, controlled by abutments to adjust penetration depth and angle, allowing for secure and repeatable attachment and detachment of objects to various surfaces without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamping device is used to attach objects to fabric or clothing, then the object can be securely fastened and protected from theft or accidental loss, but the device becomes cumbersome and inconvenient for frequent attachment and detachment
Solution Approach 1:
The clamping device is divided into two separable parts: a clamp body and a magnet link. The magnet link can be detached from the object and attached to the clamp body, allowing the clamp to remain on the fabric while the object is quickly swapped by simply detaching and reattaching the magnet link.
Solution Approach 2:
The magnet link is extracted as a separate, removable component from the clamp assembly. This allows the magnet link to be independently attached to different objects while the clamp body remains fixed on the fabric, enabling quick object changes without removing the entire clamping device.
2Reliability
If a clamping device is used to securely fasten objects to fabric, then the object can be firmly gripped in place, but the device damages the fabric or clothing material
Solution Approach 1:
The traditional mechanical clamping action that directly compresses and damages fabric is replaced with a magnetic field-based attachment system. The magnet link creates a magnetic force field that securely holds the object without requiring direct mechanical compression of the fabric, thereby preventing material damage while maintaining firm grip.
Solution Approach 2:
The magnet link acts as an intermediary between the object and the clamp body. It transmits the holding force through magnetic attraction rather than direct mechanical contact with the fabric, distributing the force evenly and preventing localized damage to the material.
3Ease of operation
If a magnetic link system is used for easy attachment and detachment, then the user experience is simplified, but the solution is limited to thin and flexible fabric that does not get damaged easily by clamping
Solution Approach 1:
The clamp body is designed with a universal structure that can accommodate various fabric types, thicknesses, and materials. The adjustable clamping mechanism and versatile magnet link configuration allow the same device to securely attach to different surfaces including thin fabric, thick material, mesh, grids, and fibers, making the system universally applicable across multiple applications.

AI summary
Disclosed is a fastening device and a method of removably attaching an object to a surface of a material, the fastening device including a base, rotatable around an axis of rotation; a support frame mechanically supporting the base allowing the base to rotate with respect to the support frame, the axis of rotation of the base being transverse to a reference plane of the support frame; an open-ring shaped piercing member including secured and piercing ends, secured end attached to the base, and the piercing member configured so the piercing end follows a first curved trajectory when the base is rotated; and a first abutment, on the support frame and configured to cause the piercing end of the piercing member to follow a second curved trajectory; so the plane of the second trajectory is offset by a deviation angle from the plane of the first trajectory.
