Existing machine tool frames for transporting and operating tools like saws are unstable, primarily relying on a pivot bearing for stability, which compromises safety during use.
Innovation Solution
A frame design that connects the handle and base frame parts with a resilient connection beyond the pivot bearing, incorporating a roller arrangement and modular machine mounts, allowing for easy assembly and disassembly, and utilizing the machine tool's base as a frame component to enhance stability and load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the frame relies only on a pivot bearing for stability, then the frame is simple to construct, but the stability and load-bearing capacity are insufficient
Solution Approach 1:
The patent combines the handle frame part and base frame part into a unified stable structure through multiple connection points. The resilient connection device merges the two frame parts at a second location remote from the pivot bearing, creating a combined structure that distributes loads across multiple connection points rather than relying solely on the pivot bearing, thereby significantly improving overall stability and load-bearing capacity.
Solution Approach 2:
The patent employs a resilient connection device that provides dynamic adaptation to loads. The resilient nature of the connection allows the frame to dynamically respond to varying operational forces, maintaining stability through elastic deformation rather than rigid fixed connections, which accommodates operational movements while preserving structural integrity.
2Strength
If the frame uses a resilient connection between handle and base frame parts, then the load-bearing capacity increases, but the device complexity increases
Solution Approach 1:
The resilient connection device merges the handle frame part and base frame part through a second connection remote from the pivot bearing. This additional merged connection point distributes the load across multiple structural elements, increasing the overall load-bearing capacity by sharing forces rather than concentrating them at a single pivot bearing location.
Solution Approach 2:
The patent changes the mechanical parameters of the connection by introducing a resilient connection device with specific elastic properties. This resilient connection modifies the stiffness and load distribution parameters of the frame structure, enabling it to withstand higher loads through elastic deformation while maintaining structural integrity under operational forces.
3Ease of operation
If the frame is designed for easy assembly and disassembly, then the ease of operation improves, but the stability during assembly may be compromised
Solution Approach 1:
The frame is segmented into distinct handle frame part and base frame part that can be independently assembled. The resilient connection device enables these segmented parts to be easily connected and disconnected while maintaining structural integrity during assembly. The modular segmentation allows for simple assembly operations without compromising the stability of the final assembled structure.

AI summary
The frame (10) has a handle frame part (20) movably supported with respect to a base frame part (30) between a transport position and an operating position (B) by two bearings (51, 52). The handle frame part comprises a handle section (22) that grips the frame in the transport position. The handle section is connected with the base frame part in the operating position by a handle fastening device (70) i.e. plug-in connection device, which is arranged at a distance to the bearings. The handle section forms a support (26) for supporting a machine tool (80) on a ground (U).
