Sliding Table Saw Support Plate With Splinter Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Table saws often cause surface damage to workpieces during handling and machining due to the need to slide them over a fixed workpiece support plate, and existing designs lack effective splinter protection, leading to potential tearing during sawing.
Innovation Solution
A sliding workpiece support plate with a splinter protection element, such as a rubber lip, that moves past the saw blade, reducing surface damage and providing continuous protection during sawing, and can be easily replaced or adjusted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the workpiece support plate is fixed to the support structure, then the construction is simple and stable, but the workpiece surface may be damaged during handling and feeding
Solution Approach 1:
The workpiece support plate is made movable relative to the support structure, allowing it to slide in the sawing direction. This dynamic design enables the workpiece to be fed by moving the support plate rather than sliding the workpiece over a fixed plate, thereby preventing surface damage while maintaining construction simplicity
Solution Approach 2:
The splinter protection element acts as an intermediary between the workpiece support plate and the saw blade. It provides continuous splinter protection during the sliding motion and sawing process, addressing the harmful effects without requiring complex construction changes
2Reliability
If the splinter protection element is fixed to the support structure, then the construction is simple, but splinter protection cannot be maintained when the workpiece support plate is moved
Solution Approach 1:
The splinter protection element is combined with the movable workpiece support plate rather than being fixed separately to the support structure. This merging ensures that the splinter protection element moves together with the support plate, maintaining continuous protection throughout the feeding and sawing process while eliminating the need for a separate fixed mounting structure
3Object-affected harmful factors
If the workpiece is slid over the fixed workpiece support plate for feeding, then the feeding process is simple, but the workpiece surface may be scratched
Solution Approach 1:
The workpiece support plate is made movable to enable an alternative feeding method. Instead of sliding the workpiece over a fixed plate (which causes scratches), the operator moves the support plate itself to feed the workpiece to the saw blade, thereby eliminating surface scratches while maintaining operational simplicity

AI summary
A table saw, preferably a circular table saw, with a support structure which can be placed on a support and on the upper side of which a workpiece support plate is provided, and with a saw blade projecting upwards over the workpiece support plate. The workpiece support plate is mounted so that it can slide in the sawing direction relative to the support structure and to the saw blade and has a splinter protection element arranged on a side of the workpiece support plate facing the saw blade. This side is guided past the saw blade when the workpiece support plate is moved.
