Removable Attachment Device with Elastic Gripping for Anti-Theft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft devices for elongated objects, such as eyeglasses and jewelry, fail to provide reliable and secure attachment without damaging the object, as they often require significant force, which can lead to marks or scratches, and lack adjustable gripping mechanisms.
Innovation Solution
A removable attachment device with a pivotable flap and body featuring elastically deformable raised means, such as thermoplastic elastomer or silicone ribs and grooves, that securely grip objects without damaging them, and includes a locking mechanism with complementary notches and indentations for adjustable closure and magnetic release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If significant force or pressure is applied to the U-shaped element to attach it to the body, then the temple is gripped effectively, but the temple may be damaged or marked
Solution Approach 1:
The patent changes the physical state of the gripping material from rigid to elastically deformable, allowing the material to dynamically adjust its hardness and conform to the object's shape. This enables effective gripping through elastic deformation rather than rigid pressure, resolving the contradiction between gripping effectiveness and object damage.
Solution Approach 2:
The patent uses composite construction by combining rigid structural elements (body and flap) with elastically deformable gripping surfaces (raised means made of elastomer or silicone). This composite approach allows the device to maintain structural integrity while the deformable surfaces provide gentle, adaptive contact with the object, preventing marks and scratches.
2Reliability
If the device is designed to lock reliably on the object, then unintentional or prohibited removal is prevented, but the installation and removal process becomes more complex
Solution Approach 1:
The patent divides the locking function into two independent components: a locking mechanism with complementary notches and indentations for secure attachment, and a separate magnetic release system. This segmentation allows the device to achieve reliable locking through the mechanical interlocking structure while maintaining ease of operation through the simple magnetic release action, resolving the contradiction between locking reliability and operational simplicity.
3Object-affected harmful factors
If the gripping surface is made elastically deformable to protect the object, then the object is not damaged, but the gripping force may be insufficient for reliable attachment
Solution Approach 1:
The patent changes the mechanical properties of the gripping surface from rigid to elastically deformable, enabling the material to undergo reversible deformation under load. This elastic deformation allows the gripping surface to conform to the object's shape and maintain continuous contact, generating sufficient gripping force through elastic recovery while preventing damage through controlled deformation rather than rigid pressure.

AI summary
A removable attachment device, that particularly forms an anti-theft device and/or electronic information medium, comprising a body on which a flap is mounted pivotably, wherein the body and the flap each have a substantially flat surface, wherein the flap rotates in relation to the body between a first extreme open position and a second extreme position known as the closed position in which the two respective surfaces can grip the object, wherein means are provided to lock the flap on the body temporarily and securely in the gripping position, characterized in that at least the gripping surface of the body and/or flap has/have raised or protruding means, that are elastically deformable.
