Surface Fastener Flange Structure for Cushion Adhesion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface fasteners experience flange bending due to applied loads during distribution, affecting adhesion to cushion bodies.
Innovation Solution
A surface fastener design featuring a base with bent flanges and a flexible porous member, where the porous member includes compressed portions to support loads and enhance adhesion by allowing cushion material permeation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flange is bent deeply into the cushion body to improve adhesion, then adhesion property is improved, but the flange is easily bent back by applied loads during distribution and stacking
Solution Approach 1:
A porous member is provided between the flange and the body, allowing cushion material to permeate through it. This porous structure enables the flange to be deeply embedded in the cushion body for improved adhesion while the porous member absorbs and distributes applied loads, preventing the flange from bending back during distribution and stacking operations.
Solution Approach 2:
The surface fastener combines the flange (for adhesion), the porous member (for load distribution), and the body (for structural support) into a composite structure. This composite design allows each component to fulfill its specific function: the flange provides deep embedding for adhesion, while the porous member provides load absorption, resolving the contradiction between adhesion and shape stability.
2Stability of the object's composition
If a porous member is added to support loads and maintain flange shape, then flange bent shape is maintained, but the structure becomes more complex
Solution Approach 1:
The porous member is integrated with the flange and body as a unified component rather than a separate attachment. The porous member is provided between the flange and the body, merging the load support function into the existing adhesion structure, thereby minimizing additional complexity while maintaining flange shape stability.
Solution Approach 2:
The porous member serves multiple functions simultaneously: it acts as a spacer to maintain the bent shape of the flange, a load distributor to prevent flange deformation during stacking, and a permeable medium to allow cushion material infiltration. This multi-functionality reduces the need for additional components, keeping the overall structure relatively simple.

AI summary
A surface fastener to be integrated with a surface of a cushion body includes: a base made of resin and having a first surface and a second surface that are in a front-back relationship; multiple engagement elements provided in an element region of the first surface of the base; and a porous member provided on the second surface of the base and having flexibility. The base includes a body including the element region, and a flange extending from the body and having a shape that is bent toward the second surface with respect to the body. The porous member includes a compressed portion compressed between the body and the flange.
