Cord Fastener Clasp for Rapid Adjustable Netting Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing sports netting to frames are time-consuming and not easily adjustable, making it difficult to center or reposition the netting during use, and require destructive removal methods.
Innovation Solution
A cord fastener system that includes a rugged cord and a clasp design allowing the cord to be securely wrapped around a frame and net, with a snap-in fastener for easy manipulation, enabling quick attachment and detachment without knots or traditional fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fasteners (bendable wires, zip ties) are used to secure netting to frames, then the netting can be attached, but the attachment process is time-consuming and not easily adjustable
Solution Approach 1:
The cord is divided into multiple segments with individual clasps at each end, allowing independent adjustment and attachment at different locations. This segmentation enables quick attachment by simply connecting the cord ends to the frame without complex wrapping or knotting procedures.
Solution Approach 2:
The cord and clasp assembly is designed to be dynamically adjustable during use. The cord can be easily repositioned along the frame by detaching and reattaching at different locations, and the clasp mechanism allows for quick length adjustments to center or reposition the netting as needed.
2Reliability
If traditional fasteners are used, then netting can be secured, but removal requires destructive methods and is not suitable for quick removal
Solution Approach 1:
The cord is pre-formed into a loop configuration with clasps positioned at the ends before attachment. This preliminary preparation allows the netting to be quickly secured by simply engaging the clasps with the frame, and equally quickly removed by disengaging them, eliminating the need for destructive removal methods.
3Adaptability or versatility
If adjustable fasteners are used for repositioning, then netting can be repositioned, but the fasteners become more complex
Solution Approach 1:
The simple cord and clasp assembly serves multiple functions: it secures the netting to the frame, allows for easy adjustment to center the netting, enables repositioning during use, and provides quick removal capability. This multi-functionality is achieved without increasing complexity, as the basic components perform all these operations.

AI summary
A fastener assembly for securing a string and/or netting includes a cord fastener and a cord. The cord fastener includes a clasp defining a first opening and a second opening spaced apart from the clasp. The cord is detachably coupled to the cord fastener, and includes a first end extending through the second opening, and a second end insertable into the clasp. The clasp is configured to allow the cord to be pulled through the clasp in a first direction, and to substantially prevent the cord from being pulled in a second direction that is opposite to the first direction. In some embodiments, the clasp includes a plurality of fingers that extend at an angle relative to a central axis of the second opening.
