Rafter Square Heel Apertures for Multi-Size Bolt Tightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carpenters face the inconvenience of having to search for and carry multiple wrenches to loosen or tighten bolts on circular saws and other tools at construction sites, which is time-consuming and clutters their tool belts.
Innovation Solution
A rafter square with integrated tool apertures, such as hexagonal-shaped and elongated, stepped apertures, allows carpenters to use the rafter square to tighten or loosen bolts without needing additional wrenches, by directly engaging with fastening mechanisms like hexagonal bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If carpenters carry multiple wrenches for different bolt sizes, then they can tighten or loosen bolts on circular saws and other tools, but this clutters their tool belts and increases the quantity of tools they must carry
Solution Approach 1:
The rafter square is designed with multiple aperture configurations (circular, hexagonal, square, rectangular) that can accommodate different bolt sizes and types. This allows a single tool to perform multiple functions: marking angles and serving as a wrench for various fastener sizes, eliminating the need to carry multiple specialized wrenches
Solution Approach 2:
The patent combines the angle-marking function of the rafter square with the wrench function by integrating apertures directly into the tool body. The apertures are positioned and sized so that the rafter square can simultaneously serve as a marking tool and a fastening tool, merging two previously separate tool functions into one
2Reliability
If carpenters search for a proper wrench in a remote area, then they can find the correct tool, but this is time-consuming and interrupts their workflow
Solution Approach 1:
The rafter square is pre-configured with multiple aperture types and sizes before the carpenter arrives at the jobsite. This preliminary preparation ensures that the correct aperture for any given fastener is already available in the tool, eliminating the need to search for or retrieve the appropriate wrench during the workflow
Solution Approach 2:
The rafter square is designed to be self-sufficient by incorporating all necessary aperture configurations directly into its structure. The tool serves itself by providing the correct aperture for different fastener types without requiring external assistance or additional tools, allowing carpenters to immediately address fastening needs
3Adaptability or versatility
If the rafter square has multiple aperture configurations for different fastener sizes, then it can accommodate various bolt types, but this increases the complexity of the tool design
Solution Approach 1:
The rafter square is divided into functional segments with distinct aperture configurations positioned at specific locations. Each aperture type (circular, hexagonal, square, rectangular) is placed in a designated area of the tool body, allowing the complex multi-functional design to be organized into manageable, non-interfering segments that maintain overall tool simplicity

AI summary
A rafter square having an integrated tool aperture is disclosed. A tool aperture is formed in the heel of a rafter square which may be used to loosen or tight bolts in a tool such as on a circular saw for example. The heel may have a single, hexagonally shaped aperture to accommodate a hex bolt commonly found on circular saws in an embodiment. The tool aperture may be shaped in an elongated, stepped shape to accommodate multiple sizes of bolts.
