Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating hand-held power tools lack effective tool guidance, leading to suboptimal workpiece interaction and increased risk of tears or inaccuracies during cutting or drilling operations.
Innovation Solution
A contact device with a tool support surface and guide arrangement that allows for precise adjustment and stabilization of the tool relative to the workpiece, incorporating a magnet for enhanced tool alignment and reduced vibrations, along with a depth adjustment scale and clamping mechanism for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carriage-like contact device is used for guiding the tool, then linear movement in the direction of the workpiece is enabled, but tool guidance for oscillating tools is not suitable and work quality deteriorates
Solution Approach 1:
The contact device is designed to move dynamically with the oscillating tool rather than constraining it in a fixed carriage manner. The contact body can adjust its position relative to the tool, allowing it to accommodate the oscillating motion while maintaining proper guidance and contact with the workpiece surface.
2Ease of operation
If the tool is not laterally supported when penetrating the workpiece, then tool movement freedom is maintained, but vibrations increase and tears occur on the workpiece
Solution Approach 1:
The contact body acts as an intermediary between the tool and the workpiece. It provides lateral support to the tool during penetration through the workpiece, reducing vibrations and preventing tears, while still allowing the tool to maintain its oscillating motion and freedom of movement.
3Manufacturing precision
If the tool is laterally supported by the contact device, then vibrations are reduced and work quality improves, but the device complexity increases
Solution Approach 1:
The contact body is integrated with the guide arrangement in a unified structure. The guide rods and clamping mechanisms are combined with the contact body itself, creating a compact device that provides both lateral support and guidance functionality without requiring separate complex subsystems.
4Stability of the object's composition
If the contact body is firmly connected to the guide arrangement, then structural stability is improved, but adjustability and ease of repair deteriorate
Solution Approach 1:
The contact device is divided into separable components: the contact body, the guide arrangement, and the clamping mechanism. These segments can be firmly connected during operation for stability, but can also be detached from each other for ease of repair and replacement, allowing maintenance without replacing the entire device.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved tool guidance and stabilization, reducing tears and ensuring precise cuts by maintaining optimal tool alignment and minimizing vibrations, thereby enhancing the quality of workpiece machining.
Implementation Method 1
at least one magnet, for example a permanent magnet, electromagnet or both, is arranged in the area of the tool support surface, which generates a magnetic field that attracts the tool in the direction of the tool support surface
