Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring devices for inclined members lack a comprehensive solution for accurately measuring both the angle and pitch of top and bottom surfaces, particularly in scenarios where access is limited or when precise cutting angles are required for lumber.
Innovation Solution
A protractor with integrated angle and pitch indicia, coupled with a bubble level and two pivotally adjustable wands, allows for the measurement of angles and pitches on both top and bottom surfaces of inclined members, facilitating accurate cutting angle determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single measuring device is used for inclined members, then the device complexity is reduced, but the measurement precision for both top and bottom surfaces deteriorates
Solution Approach 1:
The protractor is designed with dual functionality to measure both top and bottom surfaces of inclined members. It includes angle indicia for measuring angles relative to the horizontal and pitch indicia for measuring roof pitch angles, allowing a single device to perform multiple measurement tasks that previously required separate tools.
Solution Approach 2:
The protractor incorporates both angle and pitch measurement scales on the same device, adding a dimensional aspect to the measurement capability. The bubble level provides vertical reference while the indicia provide angular reference, creating a two-dimensional measurement system that captures both orientation and inclination.
2Measurement precision
If separate measuring devices are used for top and bottom surfaces, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The protractor is designed with dual functionality to measure both top and bottom surfaces of inclined members. It includes angle indicia for measuring angles relative to the horizontal and pitch indicia for measuring roof pitch angles, allowing a single device to perform multiple measurement tasks that previously required separate tools.
3Measurement precision
If a protractor with multiple indicia is used, then the measurement precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The protractor features clearly differentiated angle indicia and pitch indicia with distinct scales and markings. The bubble level is positioned to provide a clear visual reference for horizontal alignment, while the indicia are arranged to allow simultaneous reading of both angle and pitch measurements without confusion.

AI summary
An angle measuring assembly includes a protractor that is positionable against an inclined member. The protractor has angle indicia printed thereon and pitch indicia printed thereon. A bubble level is coupled to the protractor to indicate the angle of a top surface of the inclined member. A first wand is pivotally coupled to the protractor to facilitate the user to measure cutting angles on lumber. A second wand is pivotally coupled to the protractor and the second wand is aligned with respective angle indicia and respective pitch indicia when the protractor is positioned against a bottom surface of the inclined member. In this way the second wand indicate the angle and pitch of the bottom surface.
