Movable Table Saw Support Plate With Integrated Splinter Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table saw designs often result in surface damage to workpieces during handling and processing due to the need to push the workpiece over a fixed support plate, leading to scratches and tearing during sawing.
Innovation Solution
A table saw design featuring a workpiece support plate that is mounted displaceably in the sawing direction relative to the support structure and saw blade, equipped with a splinter protection element that moves with the support plate, providing protection between the workpiece and saw blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed workpiece support plate is used in conventional table saws, then the structure is simple and stable, but the workpiece surface is damaged due to scratching when pushed over the support plate
Solution Approach 1:
The workpiece support plate is made movable relative to the saw blade along the sawing direction, transforming from a fixed structure to a dynamic one. This allows the support plate to be positioned optimally for different workpiece sizes and shapes, preventing surface damage while maintaining structural simplicity
Solution Approach 2:
The table saw is divided into independent movable components: the workpiece support plate can move separately from the main support structure, and the splinter protection element is attached to the movable plate rather than being fixed to the stationary structure. This segmentation enables flexible positioning without overall structural complexity
2Ease of operation
If the workpiece support plate is made movable to reduce surface damage, then workpiece handling is improved, but the device complexity increases
Solution Approach 1:
The workpiece support plate utilizes the natural feeding motion of the operator to move along the sawing direction. The plate's movement is passive and self-driven by the workpiece insertion action, eliminating the need for motors, actuators, or complex mechanical drive mechanisms
Solution Approach 2:
The splinter protection element is combined with the movable workpiece support plate as an integrated assembly. This merging ensures that the protection element automatically follows the plate's movement without requiring separate mounting mechanisms, reducing overall device complexity
3Object-affected harmful factors
If a dedicated fixed mounting structure for splinter guard is added, then splinter protection is improved, but the design complexity increases
Solution Approach 1:
The movable workpiece support plate serves as an intermediary carrier for the splinter protection element. Instead of directly mounting the protection element to the stationary support structure, it is attached to the movable plate, which automatically positions the protection element correctly relative to the saw blade during operation
Solution Approach 2:
The movable workpiece support plate performs multiple functions: it supports the workpiece during cutting, provides a mounting base for the splinter protection element, and enables positioning adjustments. This multi-functionality eliminates the need for dedicated fixed mounting structures for the splinter guard

AI summary
The invention relates to a table saw (1), preferably a table circular saw, comprising a support structure (2), which can be placed on a base and on the top side of which a workpiece support plate (4) is provided, and comprising a saw blade (5), which protrudes upward from the workpiece support plate (4). The workpiece support plate (4) is mounted for sliding relative to the support structure (2) and to the saw blade (5) in a sawing direction (y) and has a splinter protection element (6), which is arranged on a side (7) of the workpiece support plate (4) facing the saw blade (5). Said side is guided past the saw blade (5) as the workpiece support plate (4) is slid.
