Adjustable Templating Device for Beam Angle and Length Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior templating devices lack an adjustable length measuring capability combined with angle measurement functionality, limiting their effectiveness in preparing beams that need to fit between surfaces with precise angle and length specifications.
Innovation Solution
A templating device comprising a pair of protractors and a rod with opposed ends, where each protractor segment is pivotally engaged and selectively fixable, allowing for adjustable and fixed length measurements, enabling precise angle and length templating and cutting of beams to fit between surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed length measuring device is used in combination with an angle measurement device, then the device structure is simple, but the length measurement capability is not adjustable
Solution Approach 1:
The measuring device is divided into two functional segments: a protractor component for angle measurement and a rod component for length measurement. The rod can be selectively positioned and fixed at various lengths along the protractor, allowing independent adjustment of measurement parameters while maintaining a relatively simple overall structure
Solution Approach 2:
The protractor-rod combination serves multiple functions: the protractor measures angles, the rod measures lengths, and their integrated design allows simultaneous capture of both angle and length parameters in a single positioning operation, eliminating the need for separate measurement tools
2Measurement precision
If an adjustable length measuring device with angle measurement at both ends is designed, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The protractor and rod are merged into a single integrated measuring instrument where the rod is positioned relative to the protractor scale. This combination allows simultaneous measurement of both angle and length from the same device positioning, improving measurement precision without requiring multiple separate instruments
Solution Approach 2:
The rod is designed to be movable and adjustable along the protractor, allowing dynamic repositioning to measure different lengths and angles. The rod can be fixed at any position during the measurement process, providing flexibility and precision while maintaining a relatively simple mechanical structure

AI summary
A templating device for preparing beams includes a rod that has opposed ends, each of which is both slidably engageable and fixedly engageable to a first segment of a respective protractor of a pair of protractors, such that the first segment extends linearly from the rod. The first segment is pivotally engaged to a second segment, which is selectively fixably positionable relative to the first segment. The rod and the first segments are positioned between a pair of surfaces, with each second segment positioned flush to a respective surface. A user fixes the second segment relative to the first segment to provide a respective angle measurement and a length measurement between the surfaces, and then templates these measurements onto a beam. The user then can cut the beam to length, with the ends of the beam angled so that the beam fits between the pair of surfaces.
