Portable Saw Mount System with Foot Throttle for Precision Masonry Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved systems and methods to make precise masonry cuts with hand-held cut-off saws, which lack the precision and control of tub saws while being less expensive and more portable.
Innovation Solution
A portable saw mount system that includes a stand, a base unit with a saw mount to hold the power saw in a fixed position, and a hands-free throttle controller to operate the saw motor, allowing for precise and efficient cutting without the need for manual throttle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hand-held cut-off saw is used for masonry cutting, then portability and cost are improved, but cutting precision and control are worsened
Solution Approach 1:
The system divides the cutting operation into two independent functions: the hand-held cut-off saw provides portability and cutting power, while the separate guide rail system provides precision and stability. This segmentation allows each component to optimize its specific function without compromise.
Solution Approach 2:
The guide rail system acts as an intermediary between the operator and the cut-off saw, providing a stable reference framework that constrains the saw's movement path. This intermediary structure enables precise cutting without requiring the saw itself to be rigid or heavy.
2Adaptability or versatility
If a hand-held cut-off saw is used for masonry cutting, then portability and cost are improved, but operator control and safety are worsened
Solution Approach 1:
The system separates the control functions: the guide rail system handles positioning and stability, while the operator controls only the forward motion and throttle. This segmentation reduces the cognitive and physical burden on the operator.
Solution Approach 2:
The guide rail system automatically maintains proper alignment and stability during cutting, reducing the need for constant operator adjustment and intervention. The system serves itself by providing inherent guidance and support.
3Device complexity
If manual throttle control is used during cutting, then device simplicity is improved, but cutting precision and safety are worsened
Solution Approach 1:
The guide rail system serves as an intermediary that provides passive mechanical guidance and stability, allowing simple manual throttle control to achieve precise results. The intermediary structure compensates for the simplicity of the control mechanism.
Solution Approach 2:
The system replaces complex automated throttle control mechanisms with simple manual control, relying instead on the mechanical precision of the guide rail system to maintain cutting accuracy. This substitution achieves precision through mechanical guidance rather than electronic control.

AI summary
Systems and methods for a table-mounted stand that houses a hand-held masonry cut-off saw. In some embodiments, the stand provides a fixed mount that keeps the saw stationary while the operator is allowed to feed the work piece through the saw with both hands. In some embodiments, the stand is configured to mount and un-mount the saw without the need for separate tools or time-consuming restraints. In some embodiments, the stand includes a throttle control that is activated via foot control, which allows for two-hand manipulation of the work piece being cut by the saw mounted on the stand. In some embodiments, the two-handed work-piece manipulation provided by the stand allows for precise curved and multi-angled cuts. In some embodiments, the stand is made of lightweight construction (e.g., aluminum) for ease of setup and mobilization.
