Mitre Saw Base Handle Layout for Balanced Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art chop saws are unwieldy to carry, often requiring users to hold the base assembly with both hands or rely on a carrying handle, which can be cumbersome and uncomfortable.
Innovation Solution
The mitre saw design incorporates a base assembly with contoured handles positioned to align with the center of gravity, allowing for comfortable carrying by distributing the weight evenly and providing a larger workpiece support surface without adding significant weight, along with a carrying handle that reduces the need for flexion and strain on the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users carry the mitre saw by holding the base assembly with both hands or by the carrying handle, then the saw can be transported, but it becomes unwieldy and cumbersome
Solution Approach 1:
The base assembly incorporates contoured handles with finger recesses at specific locations to optimize grip and weight distribution. The handles are strategically positioned to balance the saw's weight, making it easier to carry with reduced user fatigue.
Solution Approach 2:
The contoured handles act as intermediaries between the user's hand and the base assembly. The finger recesses in the handles provide a secure gripping interface that distributes the weight more effectively across the user's hand, reducing strain and improving carrying comfort.
2Ease of operation
If the base assembly includes contoured handles with finger recesses, then carrying comfort is improved, but the device complexity increases
Solution Approach 1:
The contoured handles are integrated directly into the base assembly structure, merging the carrying function with the base assembly. This integration adds carrying comfort features without requiring separate, complex carrying mechanisms, thus minimizing the increase in device complexity.

AI summary
A miter saw (100) has a base assembly (12) and a rotatable table (14) disposed on the base assembly (12). The rotatable table (14) is rotatable about a substantially vertical miter axis and has a substantially horizontal workpiece-supporting plane . A saw assembly (18) is connected to the table (14) and includes a blade (22). The blade (22) is movable downwardly from a first position where the blade (22) is above the workpiece-supporting plane to a second position where a portion of the blade (22) is below the workpiece-supporting plane. The base assembly (12) has a top surface and a first handle (12H) disposed on the top surface, with a first hole (12O) on the top surface extending through the base assembly (12), the first hole (12O) being configured to allow a user to extend the user's hand therethrough and grip the first handle (12H).
