Power Tool Attachment Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angle attachments for portable power tools are cumbersome to handle due to the complexity in changing the axis of rotation of the output element relative to the drive element, requiring release and re-fixing at different angles.
Innovation Solution
An attachment with a drive part and an output part that are rotatable about an angle positioning axis, featuring adjustable angle fixing bodies that can move radially or transversely to allow for easy adjustment between angle fixing and adjustment positions, enabling simple and reliable orientation changes without the need to re-fix the attachment to the power tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the attachment is released and re-fixed at different angle positions to change the axis of rotation, then the angle positioning can be adjusted, but the handling becomes cumbersome
Solution Approach 1:
The angle fixing body is made adjustable between a first position (for fixing) and a second position (for adjustment), allowing the attachment to dynamically transition between locked and unlocked states. This enables smooth angle changes without releasing the attachment from the power tool, resolving the contradiction between adaptability and ease of operation.
2Device complexity
If the angle fixing bodies are fixed in position, then the attachment structure is simple, but the angle adjustment requires releasing and re-fixing the attachment
Solution Approach 1:
The angle fixing body transitions from a static fixed structure to a dynamic adjustable structure with two positions: first position for fixing the attachment at a specific angle, and second position for releasing to allow angle adjustment. This maintains structural simplicity while enabling versatile angle changes.
Solution Approach 2:
The angle fixing body's position parameter is changed between two states (fixed and adjustable), allowing the system to switch between maintaining a specific angle and allowing angle changes. This resolves the contradiction by making the fixing mechanism itself adjustable rather than requiring complete attachment release.

AI summary
An attachment for a portable power tool, in particular a screwdriver machine or drilling machine, wherein the attachment has a drive part with a drive element and an output part with an output element for driving a work tool, wherein the drive element is able to be coupled to a machine output element of the portable power tool in order to drive the attachment and is connected or coupled to the output element via a transmission for driving the output element, and wherein the drive part has, on a drive side, a fastening device for releasably fastening the attachment to the portable power tool for conjoint rotation with respect to an angle positioning axis. Provision is made for the output part to be rotatable about the angle positioning axis relative to the drive part into at least two mutually different angle positions.
