Transportable Saw Bench Support Arms for Tilting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transportable processing units, such as circular table saws, face challenges in balancing operational safety and transportability due to limited tilting stability during operation, which can lead to accidents and inefficient handling.
Innovation Solution
The design incorporates support arms that can be pivoted from a transport position to a working position, increasing the footprint in at least one horizontal direction, thereby enhancing tilting stability, while also featuring a safety device to ensure the unit can only be operated when in the working position, and engagement structures for stable stacking and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support structure uses a compact box-shaped design for transportability, then the unit is easy to transport and handle, but the tilting stability during operation is insufficient
Solution Approach 1:
The support arms are designed to be movable between a retracted transport position and an extended working position. This dynamic configuration allows the footprint to change from compact during transport to enlarged during operation, resolving the contradiction between transportability and operational stability
Solution Approach 2:
The support structure is divided into a fixed box-shaped base and separate movable support arms. This segmentation allows the main body to remain compact for transport while the support arms can be independently positioned to provide stability during operation or retracted for mobility
2Stability of the object's composition
If the support arms are extended to increase footprint for stability, then tilting stability improves, but the unit becomes more complex to position and operate
Solution Approach 1:
The support arms are equipped with automatic locking mechanisms that engage with locking surfaces when the arms reach the desired position. This self-locking feature eliminates the need for manual securing operations, reducing positioning complexity while maintaining the ability to extend the footprint for stability
3Ease of operation
If the unit is designed to be easily transported, then handling is simplified, but operational safety is compromised due to limited stability
Solution Approach 1:
The movable support arms provide dynamic adaptability, allowing the unit to transition from a compact transport configuration to a stable operational configuration. This ensures safety during operation through enlarged footprint while maintaining ease of handling during transport
Solution Approach 2:
The support arms act as intermediaries between the compact box-shaped body and the base surface. By extending these arms, the unit creates a larger contact area with the base, providing operational safety without compromising the compact design for handling

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design improves operational safety by increasing tilting stability during use while maintaining good transportability and handling, ensuring the unit can only be operated when safely positioned and preventing accidental activation during transport.
Implementation Method 1
each of the support arms is mounted on the base body so that it can pivot about a respective vertical axis of rotation

AI summary
The invention relates to a transportable machining unit (10), particularly a circular saw bench, for machining a workpiece with a tool (1), said unit comprising a box-type supporting structure (2) that can be placed on a base and has a workpiece-supporting plate (4) that can be used to receive the workpiece to the machined, and a drive device (73) for mechanically driving the tool (1), which is at least partially arranged in the supporting structure (2) and is attached thereto in an operationally prepared manner, such that, during the machining of the workpiece by means of the tool (1) driven by the drive device (73), the drive device (73) remains at least partially arranged in the supporting structure. According to the invention, the supporting structure (2) comprises supporting arms (5) which define a standing surface of the supporting structure (2), in a state in which the supporting structure (2) is placed on the base, and which can be positioned selectively in a transport position or in a working position, the standing surface of the supporting structure (2) being larger in at least one horizontal direction in the working position than in the transport position.
