Movable Table Saw Splitter for Kickback Prevention and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table saw splitter support structures require cumbersome removal and reinstallation for operations like fluting or grooving, as they protrude from the table surface, leading to potential loss and inefficient workflow.
Innovation Solution
A support structure incorporating a lock device and an ejecting mechanism that allows the splitter to be locked and moved between operational and storage positions, enabling it to be easily ejected from the table surface without protrusion, using a guide device and an engaging member for remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the splitter is mounted on the splitter base that is disposed below the table, then the splitter can perform kickback preventing function during cutting operations, but it requires loosening bolts to remove the splitter making mounting and removing operations very troublesome
Solution Approach 1:
The splitter is designed to be movable between a first position (protruding above the table surface for kickback prevention) and a second position (retracted below the table surface). The movable support structure allows the splitter to be dynamically repositioned without requiring removal of fastening elements, thus maintaining reliability while improving ease of operation.
Solution Approach 2:
The position of the splitter relative to the table surface is changed as a variable parameter. By controlling the position of the splitter between protruding and retracted states, the system adapts to different operational requirements (cutting operations vs. fluting/grooving operations) without requiring complete removal or reinstallation.
2Reliability
If the splitter protrudes from the table surface for cutting operations, then it can prevent kickback phenomenon, but it cannot be easily stored and may be lost when not in use
Solution Approach 1:
The splitter transitions from a static mounted state to a dynamic movable state, allowing it to be repositioned between protruding (for kickback prevention) and retracted (for storage) positions. This dynamic capability ensures the splitter remains accessible and identifiable when not in use, preventing loss while maintaining its protective function when needed.
Solution Approach 2:
The support structure provides multiple functions: it secures the splitter during cutting operations, enables easy retraction for storage, and maintains the splitter in an accessible position when not in use. This multi-functionality addresses both kickback prevention and storage concerns within a single integrated system.
3Adaptability or versatility
If the splitter is removed for fluting or grooving operations, then it allows access for these operations, but it requires troublesome removal and reinstallation procedures
Solution Approach 1:
The splitter is designed to move smoothly between positions along the cutting direction. The movable support structure with guide slots and engaging members enables the splitter to be easily retracted below the table surface without requiring loosening of fastening elements, thus providing operational flexibility while maintaining ease of operation.
Solution Approach 2:
The splitter can be preliminarily retracted to a storage position below the table surface before fluting or grooving operations begin. This preliminary action eliminates the need for complete removal and reinstallation, as the splitter is already in the correct position for these alternative operations.

AI summary
A support structure for a splitter of a cutting tool includes a lock device and a moving device. The lock device can lock and unlock the splitter at a storage position. The moving device can move the splitter from the storage position to an ejected position, in which a part of the splitter extends above an upper surface of a table of the cutting tool, when the lock device unlocks the splitter at the storage position.
