Circular Saw Bench Clamping Device for Workpiece Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools with circular table saws face challenges in maneuvering work pieces of different sizes, particularly large and heavy ones, as they require significant force to keep the work piece in contact with the table and prevent tilting, while also needing the user to perform other tasks simultaneously.
Innovation Solution
A clamping device is used to fix the vertical position of the work piece relative to the table, allowing the user to focus on infeed forces alone, with the clamping device supporting the work piece and absorbing tilting forces, and a work piece contacting element that engages from below, providing relief and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually holds and guides large work pieces during machining, then the work piece can be kept in contact with the table surface and sliding fence, but the user must exert considerable forces and cannot simultaneously perform other tasks
Solution Approach 1:
The work piece support device enables the work piece to be supported and guided automatically during machining. The device includes a support element that contacts the work piece and a positioning element that engages with the sliding fence, creating a self-supporting system that eliminates the need for continuous manual intervention while allowing the user to perform other tasks
Solution Approach 2:
The work piece support device acts as an intermediary between the work piece and the machining system. It provides a mechanical connection through the support element and positioning element that transfers and stabilizes the work piece during machining, freeing the user from direct manual control while maintaining precise positioning
2Ease of operation
If work piece supports protrude beyond the edges of the work table to facilitate maneuvering of large work pieces, then the work piece can be better supported, but the device complexity and set-up time increase significantly
Solution Approach 1:
The work piece support device is nested within the existing work table structure. The support element extends from beneath the table surface to contact the work piece, while the positioning element engages with the sliding fence that is already part of the machining system. This nested configuration provides enhanced support functionality without adding external protruding structures
Solution Approach 2:
The work piece support device utilizes existing components of the machining system for multiple functions. The positioning element works with the sliding fence to provide both positioning and support functions, while the support element simultaneously supports the work piece and allows for adjustment. This multi-functional design eliminates the need for separate protruding support structures
