Adhesive Fastener Assembly With Reinforcement for Shear Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener arrangements require high design effort and production costs due to complex mechanisms for releasing adhesive agents, and they struggle to withstand both pressure and shear forces without detaching from substrates.
Innovation Solution
A fastener arrangement featuring a metallic reinforcement part with a press-on element that displaces to release adhesive agent through openings, providing a stable and reliable attachment to substrates, with a holder and retaining ring for additional stabilization, and an optional tube for separate adhesive agent storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a push-through means in the shape of a thorn or point is used to create a hole in the reservoir wall, then adhesive agent can be released, but design effort and production costs increase due to high mounting precision requirements
Solution Approach 1:
The push-through means is extracted from the object itself and integrated into the fastener, specifically into the press-on element. This separates the adhesive release function from the object's mounting requirements, allowing the push-through means to be positioned without stringent tolerance requirements on the object side.
Solution Approach 2:
The fastener acts as an intermediary between the object and the substrate. By incorporating the push-through means in the fastener's press-on element, it mediates the adhesive release process independently of the object's mounting precision, resolving the contradiction between ease of manufacture and manufacturing precision requirements.
2Productivity
If adhesive agent is stored in the object itself and released by button-pushing, then fastening can be produced rapidly, but design effort increases due to integration requirements
Solution Approach 1:
The system is segmented into distinct functional components: the object with reservoir, the fastener with press-on element containing push-through means, and the substrate. This segmentation allows rapid assembly while distributing complexity across separate components rather than requiring complex integration within a single component.
Solution Approach 2:
The press-on element is designed to perform multiple functions: it bounds the adhesive reservoir, contains the push-through means, and provides the actuation mechanism. This self-service design reduces overall device complexity while maintaining rapid fastening capability.
3Adaptability or versatility
If multiple displaceable reservoirs are used for adhesive and hydrophilic substance, then mixing can occur, but design effort increases due to displacement and mixing mechanisms
Solution Approach 1:
The fastener merges multiple functions into a single component: the press-on element combines the adhesive reservoir bounding, push-through means housing, and actuation mechanism. This merging reduces device complexity while maintaining the capability for adhesive release and mixing through the integrated design.

AI summary
A fastener arrangement with a fastener designed for fastening to a substrate by means of an adhesive agent, and with an object having an object mount, whereby the object mount can be fixed to the fastener fastened to the substrate. The fastener has a reinforcement part composed of a metallic material, the side wall elements of which are mounted between a retaining ring and edge segments of a holder. The side wall elements of the reinforcement part are designed for fixing the object mount. The fastener has a press-on element bounding an adhesive reservoir, wherein adhesive agent can be guided out of the adhesive reservoir through openings in the reinforcement part and in the holder by a displacement of the press-on element in the axial direction, such that the adhesive agent fixes the fastener to the substrate.
