Miter Saw Extendable Support Extensions for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saws, such as miter and pull saws, face challenges in securely and stably supporting workpieces, especially longer ones, while also requiring compact designs for transport and avoiding the inconvenience of separate support blocks that can be easily misplaced.
Innovation Solution
The implementation of extendable support extensions with connecting webs that can be pushed into recesses on the lower table for compact transport, and extended for stable support, allowing for adjustable and separate use as a support block, enhancing stability and reducing the risk of misplaced components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If support blocks are attached to the lower table, then workpiece support stability is improved, but the saw becomes unwieldy and difficult to transport
Solution Approach 1:
The extension arm is designed to be movable rather than fixed, allowing it to be extended when needed for workpiece support and retracted for compact transport. The extension arm can be pushed into or pulled out from the lower table, providing dynamic adaptability between transport mode and work mode.
2Adaptability or versatility
If support extensions are extended for long workpieces, then support capability is improved, but the saw size increases making transport difficult
Solution Approach 1:
The extension arm is nested within or integrated into the lower table structure when retracted, allowing it to be stored compactly during transport. The extension arm can be pushed into the lower table or pulled out as needed, effectively hiding the extended portion within the main body when not in use.
3Adaptability or versatility
If separate support blocks are used, then support functionality is improved, but the risk of forgetting components increases
Solution Approach 1:
The extension arm is integrated with the lower table as a unified structure, eliminating the need for separate support blocks. The extension arm is either permanently attached or easily reattachable to the lower table, ensuring it is always available when needed and cannot be forgotten or misplaced.

AI summary
The present invention relates to a miter saw (10) with a base table (12) for receiving and supporting a workpiece (W) to be machined, wherein the base table (12) comprises at least two support extensions (20) with a support section (26) that serves to receive and support the workpiece (W) to be machined, wherein each support extension (20) is movable back and forth between a retracted position and an extended position relative to the base table (12) and for this purpose has at least one connecting web (22) which, for connecting the support extension (20) to the base table (12), can be inserted at least partially into a corresponding recess on the base table (12) and, for releasing the connection, can be completely withdrawn from this recess, and at least one support leg (24) for stable support of the support extension (20).wherein the support extension (20) can be used as a separate support for the workpiece (W) to be machined in a position of the connecting bridge (22) detached from the lower table (12), and wherein the at least two support extensions (20) can be connected to each other in a state detached from the lower table (12).
