Guide Cart Pivot Device for Power Tool Vibration Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held power tools, such as cut-off machines, experience imprecise guiding due to vibration decoupling from the guide cart, leading to impaired tool alignment and vibration issues during operation.
Innovation Solution
A guide cart with a pivot device that includes both fixation and support mechanisms, allowing direct support of the tool during operation and enabling compensation of cutting forces, thereby enhancing guiding precision without requiring separate support components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power tool is secured on the guide cart using a pivotable lever with fixation means, then the fixation is simple and quick, but the guiding action becomes imprecise due to vibration decoupling
Solution Approach 1:
The invention combines the fixation means and support means into a single integrated pivot device. The pivotable lever (fixation means) and the support component are merged into one unified structure that performs both fixation and support functions simultaneously, eliminating the need for separate components while ensuring precise guiding action.
Solution Approach 2:
The pivot device is designed as a multi-functional component that simultaneously provides fixation (through the pivotable lever) and support (through the integrated support means). This universal design allows a single component to fulfill multiple functions: securing the power tool and providing precise guiding action, thereby resolving the contradiction between ease of operation and guiding precision.
2Ease of operation
If vibration damping elements are used to decouple handles from the drive motor and tool, then operator comfort is improved, but tool alignment precision deteriorates
Solution Approach 1:
The invention introduces a new intermediary element - the integrated pivot device with support means - that acts as a mediator between the vibration-damped handle system and the guide cart. This intermediary provides a direct support path for the tool that bypasses the vibration damping elements, ensuring precise guiding action while maintaining operator comfort through the handle decoupling.
3Manufacturing precision
If a separate support component is added to the guide cart, then guiding precision is improved, but device complexity increases
Solution Approach 1:
The invention avoids increasing device complexity by merging the support function into the existing pivot device structure. Rather than adding a separate support component, the support means is integrated into the pivotable lever assembly, maintaining a simple device architecture while achieving precise guiding action.

AI summary
A guide cart for a hand-held power tool with a driven tool has a pivot device that is pivotable between an open position and a fixation position. A fixation elements is provided that releasably secures the power tool on the guide cart. The fixation element is secured on the pivot device. The pivot device has at least one support for supporting a tool of the power tool in the fixation position of the pivot device. The guide cart has a holder for the power tool, wherein holder is provided with a base plate and has at least one lateral guide for the power tool. The pivot device is supported on the base plate. The pivot device and the baseplate together form a C-shaped frame.
