Angled Fastener Tool Alignment and Board Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side angled screws and installation tools often cause damage to wood or composite boards due to rapid advancement, leading to splitting or bulging, and fail to accommodate boards of varying widths, resulting in improper alignment and unsightly gaps between boards.
Innovation Solution
A fastener with a chisel edge and inclined surfaces that pre-bore a hole by scraping material, and an installation tool with a clamping mechanism and alignment projection to ensure precise alignment and minimize damage, allowing for concealed fastening without gaps between boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional side angled screws with conical pointed tips are used, then the screw can penetrate the board, but the screw rapidly advances into the board causing splitting or bulging of the lower corner
Solution Approach 1:
The screw end includes a chisel edge and inclined surfaces that pre-bore a hole in the board before the main body of the screw advances. This preliminary action removes material and creates a cavity, allowing the screw to advance without causing splitting or bulging of the board corner.
Solution Approach 2:
The chisel edge and inclined surfaces act as an intermediary mechanism between the screw and the board. Instead of the screw threads directly engaging the board and causing rapid advancement, the chisel edge first creates a pathway, mediating the interaction to prevent harmful wedging actions.
2Measurement precision
If conventional installation tools with fixed pin positions are used, then the tool can guide screw installation, but the tool cannot accommodate boards of varying widths resulting in improper alignment
Solution Approach 1:
The installation tool includes movable pins that can be adjusted along the guide body to different positions. This dynamic adjustment capability allows the tool to adapt to boards of varying widths while maintaining precise alignment guidance for the screw installation path.
Solution Approach 2:
The installation tool is designed with adjustable pins that can accommodate multiple board widths and types. This universal design allows a single tool to properly align screws for different board configurations, eliminating the need for multiple specialized tools.
3Stability of the object's composition
If conventional tools that create gaps between boards are used, then the tool can accommodate board expansion, but unsightly gaps appear between adjacent boards
Solution Approach 1:
The installation tool allows dynamic adjustment of pin positions to accommodate board expansion and contraction. This enables the tool to maintain proper screw alignment while allowing boards to be installed with minimal gaps, preserving surface continuity while accommodating dimensional changes.

Implementation Method 1
The end of the screw can include a chisel edge and inclined surfaces that scrape a surface of the work piece to pre-bore a hole for the remainder of the screw
Implementation Method 2
the threads twisting and subsequently thrusting the screw forward

AI summary
A fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.
