Angle Divider for Miter Saw with Removable Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting molding with a miter saw often results in uneven joints due to angles not being exactly at right angles, leading to unsightly gaps between moldings and surfaces.
Innovation Solution
A tool, known as the angle divider, which accurately determines the angle between joined surfaces and transfers it to a miter saw for precise cutting, featuring a body with pivotable arms, sliding fingers, and adjustable locking mechanisms to ensure accurate cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If miter saw cutting is performed without angle measurement tool, then cutting operation is simple and fast, but cutting precision and joint accuracy deteriorate resulting in gaps between moldings
Solution Approach 1:
The angle divider is divided into separate components including a body portion, removable arm, and sliding finger that can be assembled and disassembled. This segmentation allows the tool to achieve high cutting precision when needed while maintaining simplicity for storage and transport by separating the measuring components from the main body.
Solution Approach 2:
The angle divider acts as an intermediary tool between the wall joint and the miter saw. It measures the angle at the joint location and transfers this measurement to the saw blade adjustment, serving as a mediator that bridges the gap between the installation site geometry and the cutting tool setup, thereby achieving precise cuts without requiring complex integrated equipment.
2Manufacturing precision
If angle measurement tool is used to determine joint angle, then cutting accuracy is improved, but operation time and process complexity increase
Solution Approach 1:
The angle divider allows the user to measure and determine the exact joint angle at the installation location before proceeding to the miter saw cutting operation. By performing this angle determination action in advance at the site, the subsequent cutting process becomes straightforward and quick, as the blade angle is already predetermined, thus reducing overall operation time while maintaining high joint accuracy.
Solution Approach 2:
The angle divider captures the angle geometry from the wall joint and creates a replicable measurement that can be transferred to the miter saw. This copying process involves measuring the joint angle with the divider's arms and fingers, then reproducing that same angle setting on the saw blade, enabling accurate cuts without requiring complex real-time adjustment procedures during the cutting operation.
3Productivity
If fixed angle setting is used on miter saw, then cutting operation is fast, but adaptability to different joint angles is reduced
Solution Approach 1:
The angle divider incorporates movable arms and sliding fingers that can dynamically adjust to match any joint angle configuration. The removable arm can be positioned at different angles and locked into place, allowing the tool to adapt to various wall joint geometries. This dynamic adjustability enables the user to quickly set the correct angle for different installation scenarios while maintaining efficient cutting operations.
Solution Approach 2:
The angle divider allows changes in the angular parameter by adjusting the position of the removable arm and sliding finger along the body portion. The arm can be rotated and locked at different angles, and the finger can slide to different positions on the arm, enabling the tool to accommodate a range of joint angles. This parameter variability ensures adaptability to different joint configurations while keeping the cutting process efficient.

AI summary
An angle divider includes a body portion with a proximate end and a distal end. A distal end pivot point is positioned in the distal end of the body portion. First and second removable arm are pivotally mounted to the distal end pivot point. The arms pivot with respect to the distal end pivot point. An adjustable pivot is mounted for sliding movement within an elongated slot formed in the body portion. Brackets removably interconnect the arms to the adjustable pivot. Movement of the arms results in movement of the adjustable pivot longitudinally along the body portion. A lock locks the adjustable pivot with respect to the body portion, which locks the arms in place with respect to the body portion. The removable arms can be removed from the adjustable pivot point for transport and to split the angle.
