Floor covering fasteners and adhesives removal tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for removing staples, tack strips, and adhesive residue from flooring often damage the subflooring and are inefficient, with plastic tools breaking under high use and manual methods requiring significant force, leading to scratches or dents.
Innovation Solution
A multi-purpose tool with a hardened tool steel design featuring a staple remover, tack nail puller, and glue scraper, utilizing a pincer action, forked blade, and beveled edge to remove fasteners and adhesive residue without damaging the floor, and a comfortable dual rubber handle for leverage and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screwdriver is used to wedge underneath the staple and pry it out, then the staple can be removed from the subflooring, but significant force is required which may scratch or dent the subflooring
Solution Approach 1:
The patent introduces a specialized removal tool as an intermediary between the user and the staple-subflooring system. This tool features a forked blade that slips under the staple and a prying plate with oval shape that provides leverage while distributing force, allowing staple removal without direct contact between common tools (like screwdrivers) and the subflooring surface, thus preventing scratches and dents
Solution Approach 2:
The patent changes the physical parameters of the removal tool to optimize performance. The forked blade is made thin enough to get underneath the staple but smooth enough to prevent damaging the flooring. The prying plate is designed with an oval shape and specific thickness to provide maximum leverage while maintaining control and minimizing damage risk to the subflooring
2Weight of moving object
If heavy duty staple removers are made with plastic instead of metal to cut costs, then the tool is lighter and cheaper, but the plastic degrades under high use conditions when removing large staples and eventually breaks
Solution Approach 1:
The patent employs composite material construction for the removal tool, combining different materials to achieve optimal properties. The forked blade and prying plate are made from hardened tool steel for strength and durability, while the handle incorporates dual rubber non-slip material for comfort and grip. This composite approach provides both the strength needed for heavy-duty staple removal and the reliability for prolonged use without degradation or breaking
3Ease of operation
If a common claw hammer is used to pull nails from tack strips, then the nail can be removed, but the operation requires significant force and the tool may not guide smoothly around the nail
Solution Approach 1:
The patent segments the removal tool into distinct functional components: a forked blade for engaging the nail head, a prying plate with oval shape for leverage, and a dual rubber handle for grip. This segmentation allows each component to be optimized for its specific function, enabling smooth guidance around the nail and efficient force application during nail removal from tack strips
Solution Approach 2:
The patent incorporates curved and oval shapes in the tool design, particularly the oval-shaped prying plate that provides smooth leverage points and guides the tool around the nail head. The curved surfaces allow for ergonomic hand positioning and smooth rotational motion during nail extraction, reducing operation difficulty compared to straight-edged tools
4Manufacturing precision
If adhesive residue is removed from the subflooring, then a smooth surface is provided for new flooring, but the removal process can damage the subflooring surface
Solution Approach 1:
The patent uses the specialized removal tool as an intermediary between the adhesive residue and the subflooring surface. The tool's prying plate with oval shape and controlled thickness provides a large surface area contact that distributes force evenly, allowing adhesive removal while protecting the subflooring from damage. The smooth surfaces of the tool prevent scratching during the scraping and prying actions

AI summary
The present invention is a floor covering fasteners and adhesives removal tool that allows for the quick removal of a staple, tack nail, and/or adhesives from a material without causing damage. The staple remover portion of the multi-purpose tool works with its forked blade for slipping underneath staples, and using the prying plate oval shape to free the staple. The tack strip nail puller portion of the multi-purpose tool having the nail slot is typically moved laterally relative to the nail. More specifically, the nail slot engages the nail where the force moving prying plate by the handle will sufficient to free the nail from the surface. The glue scraper portion of the multi-purpose tool has a bevel edge to allow the glue scraper to assume more nearly a right angular position to the floor surface sufficient to free the glue residue from the surface.
