Stacked Machining Unit Coupling for Stable Vertical Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportable processing units, such as circular table saws, face challenges in efficient and safe handling, storage, and transportation due to lack of stable coupling mechanisms, leading to difficulties in forming secure vertical stacks and quick transitions between operational and transport states.
Innovation Solution
Incorporating support structure coupling means with detachable, vertically tensile coupling elements, such as rotary latches and locking anchor contours, to enable stable stacking and secure vertical coupling between the transportable processing unit and box-shaped bodies, allowing for efficient storage, transport, and rapid deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If transportable processing units are designed without coupling mechanisms, then device complexity is reduced, but handling and storage efficiency deteriorates due to inability to form stable vertical stacks
Solution Approach 1:
The support structure is divided into an upper part and a lower part that can be detachably coupled together. The lower part contains coupling means for vertical stacking, while the upper part houses the processing unit. This segmentation allows the coupling mechanism to be added without complicating the entire device, as only specific parts are modified.
Solution Approach 2:
The coupling means are designed to provide multiple functions: vertical stacking for storage, stable support during transport, and quick detachment for deployment. The same coupling structure serves all these purposes, improving handling efficiency without requiring separate mechanisms for each function.
2Productivity
If coupling mechanisms are added to enable vertical stacking, then storage and transport efficiency is improved, but device complexity increases
Solution Approach 1:
The upper part of the support structure is designed to nest within or attach to the lower part, forming a compact vertical stack. The coupling means are integrated into the existing structure rather than adding external components, minimizing the increase in device complexity while enabling efficient stacking.
Solution Approach 2:
The coupling mechanism allows for quick assembly and disassembly of the vertical stacks. The detachable nature of the coupling means enables dynamic reconfiguration between stacked storage mode and deployed operational mode, improving transport efficiency without requiring permanent complex structures.
3Reliability
If the drive device is permanently attached in the lower part, then operational readiness is maintained during transport, but adaptability for different configurations is reduced
Solution Approach 1:
The processing unit is divided into separable parts: the drive device remains in the lower part while the upper part can be detached and reconfigured. This segmentation maintains operational readiness by keeping the drive device securely attached, while still allowing adaptability through reconfiguration of the upper part or stacking arrangements.
Solution Approach 2:
The drive device is pre-installed and securely attached in the lower part in a ready-to-use state before transport. This preliminary preparation ensures operational readiness is maintained during transport, while the detachable upper part allows for later reconfiguration or stacking without requiring modification of the drive device.

AI summary
The invention relates to a transportable machining unit (10), in particular a circular table saw, for machining a workpiece using a tool (1), comprising a box-like supporting structure (2), which can be set down on an underlying surface and has a lower part (3) with a workpiece-bearing plate (4), on which the workpiece which is to be machined can be positioned, and also comprising a drive device (5) which is intended for driving the tool (1) mechanically, is arranged at least to some extent in the lower part (3) and is fastened thereon in an operationally ready state, and therefore, when the workpiece is being machined by the tool (1) driven by the drive device (5), the drive device (5) remains at least to some extent in the lower part (3). According to the invention, the supporting structure (2) has supporting-structure coupling means (6), which are suitable, in a state in which the supporting structure (2) forms a vertical stack together with at least one box-like body (21; 22), for establishing a releasable, vertically tension-resistant coupling to the at least one box-like body (21; 22).
