Adjustable Shoe Fastener Driver for Flooring Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastener driving devices for tongue and groove flooring are inflexible and require different tools or shims for various board thicknesses, leading to cumbersome adjustments and potential damage from loose fasteners.
Innovation Solution
A fastener driving device with an adjustable shoe that accommodates different flooring board thicknesses by allowing the forward workpiece engaging surface to be adjusted between a minimum and maximum exposure, preventing fastener heads from protruding and causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed shoe is used in the fastener driving device, then the device can be simple in structure, but it cannot accommodate different flooring board thicknesses and requires multiple tools or shims
Solution Approach 1:
The shoe is designed with an adjustable mechanism that allows it to change its configuration dynamically. The shoe includes a body portion and a forward workpiece engaging surface that can be positioned at different exposures relative to the top surface of the shoe, enabling adaptation to various flooring board thicknesses while maintaining a single tool design.
2Reliability
If conventional fasteners are used in the pad, then the pad can be simple to manufacture, but the fasteners may become loose and work their way out of the holes, causing damage to the flooring board
Solution Approach 1:
The pad is designed with recessed holes that pre-position the fastener heads below the surface of the pad. This beforehand cushioning ensures that even if fasteners become loose, their heads remain contained within the recessed holes and cannot protrude to scratch or mar the flooring board, thus preventing damage before it can occur.
3Adaptability or versatility
If shims are used to adjust the tool for different board thicknesses, then the tool can remain fixed, but the shims become cumbersome and may be misplaced
Solution Approach 1:
The adjustment functionality previously requiring separate shim components is merged directly into the shoe structure. The shoe integrates the adjustment mechanism within itself, allowing the forward workpiece engaging surface to be repositioned relative to the top surface, thereby eliminating the need for external shims and simplifying the adjustment process.

AI summary
A fastener driving device includes a housing containing an engine for driving a fastener through a flooring board and into a sub-floor, a nosepiece through which fasteners are driven, a magazine for supplying a plurality of fasteners for the engine to drive, and a shoe mounted for movement relative to the nosepiece. The shoe locates the engine relative to the flooring board so that the fastener is driven into the flooring board at an angle. The shoe includes a bottom workpiece engaging surface for engaging a top surface of the flooring board, and the nosepiece includes a forward workpiece engaging surface for engaging a front surface of the flooring board. The forward surface extends a distance below the bottom surface. One of the bottom surface and the forward surface is movable with respect to the other to adjust the distance that the forward surface extends below the bottom surface.
