Guide-Wire Nail Fastener for Predrilled Concrete Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current construction fasteners for connecting objects to concrete are inefficient in terms of installation time, cost, and versatility, requiring multiple types of fasteners for different substrates, which hinders worker efficiency and increases costs.
Innovation Solution
A fastener design featuring a nail with a guide wire bonded to it, where the guide wire extends past the tip and has a lower Rockwell hardness than the nail, allowing the bond between them to break when driven into a predrilled hole, facilitating easy installation and removal, and using a duplex head for securement and extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wire and nail are used separately to secure an article to concrete, then the connection can be established, but the installation process becomes time-consuming and requires multiple components
Solution Approach 1:
The patent combines the wire and nail into a single integrated fastener component. The wire is bonded to the nail shaft, creating a unified device that performs both functions simultaneously. This merging eliminates the need to handle and install separate wire and nail components, directly improving installation speed while reducing component count.
Solution Approach 2:
The integrated fastener serves multiple functions: the nail provides anchoring into concrete, the wire provides connection through the article, and the combination allows for both temporary and permanent securing. This multi-functionality reduces the need for multiple specialized fasteners, improving productivity by using a single versatile component.
2Ease of operation
If conventional nails are used to temporarily secure articles to concrete, then the connection can be established, but removal requires specialized clawed tools and time
Solution Approach 1:
The fastener is designed with separable functionality where the wire can be removed independently from the nail portion. The bond between wire and nail is positioned to break during installation, allowing the wire to remain in the hole while the nail can be extracted. This segmentation enables easier removal compared to conventional nails that require clawed tools.
Solution Approach 2:
The wire acts as an intermediary element that remains in the concrete hole after installation. During removal, the wire serves as a mediator that can be pulled out first, facilitating the extraction process and reducing the time and tools needed for complete removal compared to conventional nails.
3Adaptability or versatility
If multiple types of fasteners are used for different substrates, then specific substrate requirements are met, but cost increases and worker efficiency decreases
Solution Approach 1:
The integrated fastener design with adjustable wire length and bonding configuration allows it to adapt to different substrate requirements (concrete, wood, plastic forms). This universality enables workers to use a single fastener type across multiple applications, eliminating the need to switch between different fastener types and significantly improving worker efficiency and productivity.
