Adjustable Measuring Tool With Rotating Sliding Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpenter's squares lack versatility and accuracy in marking and cutting multiple identical cuts, particularly in complex construction projects, as they are limited to fixed angles and measurements, making it difficult to achieve precise and repeatable cuts in various materials like wood and sheet rock.
Innovation Solution
A measuring tool with a body formed of planar rigid material, featuring a 90-degree and 45-degree angled segments, a removable cutting edge portion, and a sliding member that can be rotated and positioned for precise measurements and cutting, allowing for repeatable and accurate marking and cutting of materials with multiple configurations, including use as a depth gauge and plumb bob.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional carpenter's squares are used with fixed angles and measurements, then the device structure is simple, but the versatility and accuracy in marking and cutting multiple identical cuts are limited
Solution Approach 1:
The measuring tool is divided into multiple body segments (first body segment, second body segment, third body segment) that can be independently positioned and configured. Each segment provides specific measuring edges and reference surfaces, allowing the tool to be adapted to various measuring and marking tasks while maintaining a manageable overall structure.
Solution Approach 2:
The measuring tool is designed to perform multiple functions including measuring distances, marking cut lines, providing reference surfaces for cutting, and guiding saws for repeatable cuts. The combination of multiple body segments with different orientations and the sliding member enables the tool to serve as both a measuring device and a cutting guide.
2Manufacturing precision
If fixed angles and measurements are used in conventional carpenter's squares, then the device is easy to manufacture, but the precision and accuracy in achieving repeatable cuts are insufficient
Solution Approach 1:
The sliding member can be adjusted to different positions along the first body segment and locked in place, allowing dynamic adjustment of the measuring reference. This enables precise positioning for different cut depths and angles while maintaining stability during the cutting process, achieving both precision and ease of adjustment.
Solution Approach 2:
The patent replaces the traditional fixed mechanical structure of conventional squares with a system that combines fixed body segments and an adjustable sliding member. This allows for precise mechanical positioning and repeatable measurements while maintaining ease of manufacture through modular components.
3Adaptability or versatility
If multiple body segments and sliding members are added to increase versatility, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Multiple body segments (first, second, and third body segments) are connected to form an integrated measuring tool structure. The sliding member is combined with these segments to create a unified device that provides both measuring and guiding functions, reducing the need for separate tools while maintaining versatility.

AI summary
A measuring tool is provided which includes a sliding member which is in a rotational sliding engagement to the body of the tool. The sliding member is positionable for measuring distances between a first end thereof and a first body segment. A second body segment extends perpendicular from a first end of the first body segment and a third body segment extends at a 45 degree angle from a second end of the first body segment opposite the first end thereof.
