Surface Fastener Hook Groups for Screen Net Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface fasteners for attaching insect repellents to screen nets require a loop member, which can be difficult to manage and may lead to detachment issues, making it impractical for certain installations and reattachment challenging.
Innovation Solution
A surface fastener with integrally formed hook-shaped engaging elements arranged in groups on a base part, allowing attachment and detachment without a loop member, featuring a stem portion and curved engaging head for easy engagement with screen nets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a loop member is used in the surface fastener product, then the insect repellent including peripheries can be attached to the screen net, but the loop member may go off and be lost during detachment, resulting in incapability of reattaching
Solution Approach 1:
The invention extracts and eliminates the loop member from the surface fastener system. By using only the hook member with hook-shaped engaging elements that directly engage with the screen net, the patent removes the component that causes loss and detachment problems, allowing reliable attachment and detachment without the risk of losing a loop member
Solution Approach 2:
The hook member is designed to perform multiple functions: it attaches the insect repellent to the screen net, allows for easy detachment, and enables reattachment without requiring additional components. The hook-shaped engaging elements directly interact with the screen net structure, making the single component universal for both attachment and detachment operations
2Reliability
If the hook member is brought close to the loop member from the inner side of the screen for engagement, then attachment is achieved, but it becomes difficult or impracticable when the screen size or installation location does not allow hand access from the outer side
Solution Approach 1:
By removing the loop member that required hand manipulation from the outer side of the screen, the invention eliminates the accessibility constraint. The hook member can be directly engaged with the screen net from the inner side without requiring the user to reach through or around the screen structure
Solution Approach 2:
The hook-shaped engaging elements are designed to self-engage with the screen net structure through their curved geometry. The engaging elements automatically catch on the screen net when brought close, requiring minimal manual manipulation and making the attachment process feasible even in hard-to-reach locations

AI summary
In a surface fastener according to the present invention, a plurality of the hook groups and a spaced part provided between adjacent ones of the hook groups are disposed on the base part. The hook groups each include a first engaging element and a second engaging element. Each adjacent two of the engaging elements in each of the hook groups are oriented such that an element-head side of one of the two engaging elements and an element-back side of an other of the two engaging elements face each other or the respective element-back sides of the two engaging elements face each other, and each two of the engaging elements that are located across the spaced part from each other in the first direction are oriented such that the respective element-head sides of the two engaging elements face each other.
