Adjustable Power Tool Guide Device with Movable Connection Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for power tools are limited in their ability to accommodate different tool specifications and sizes, as they often require fixed adapters that are not compatible with various power tools, restricting their versatility and operability.
Innovation Solution
A guide device featuring a ruler plate, an adapter base, and adjustable connection members that can be attached to different power tools, allowing for customizable positioning and compatibility with various tool sizes, including the option to change the distance between connection members and adjust their orientation to prevent improper attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed adapters are used to attach power tools to the ruler plate, then the attachment structure is simple, but the guide device cannot accommodate different power tool specifications and sizes
Solution Approach 1:
The connection members are designed to be movable relative to the adapter base, allowing the distance between connection members to be adjusted. This dynamic adjustment capability enables the adapter to accommodate different power tool specifications and sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The adapter base is designed with multiple attaching portions and connection members that can be configured in different positions, allowing a single adapter structure to universally attach to various power tools with different attaching portion distances, eliminating the need for multiple specialized adapters.
2Adaptability or versatility
If the distance between connection members is fixed, then the adapter structure is simple, but it cannot be attached to power tools with incompatible attaching portions
Solution Approach 1:
The connection members can be moved along the adapter base to different positions, allowing users to adjust the distance between connection members to match the attaching portion distances of different power tools. This dynamic adjustment maintains ease of operation while significantly improving compatibility.
Solution Approach 2:
The adapter base is divided into multiple attaching portions at different positions, and connection members can be selectively attached to different combinations of these portions, creating segmented attachment options that accommodate various power tool configurations.
3Reliability
If connection members are fixed in position, then the device structure is simple, but improper attachment cannot be prevented
Solution Approach 1:
The connection members are designed with asymmetric features including restricting portions that prevent attachment in incorrect orientations. This asymmetric design ensures that connection members can only be properly attached in the correct orientation, preventing improper attachment while maintaining relatively simple connection member structures.
Solution Approach 2:
The restricting portions on connection members are designed in advance to prevent improper attachment before it can occur. This preliminary anti-action approach ensures that even if users attempt to attach connection members incorrectly, the asymmetric restricting portions will physically prevent such improper attachment.

AI summary
A guide device (10) may include a ruler plate (20) adapted to be fixed in position relative to the workpiece (W), an adapter base (30) adapted to support the power tool (50, 70) and movable in a process proceeding direction relative to the ruler plate (20), and a plurality of connection members (31, 43) for connecting the adapter base (30) to the power tool (50, 70). The plurality of connection members may include a front connection member (31, 43) and a rear connection member (31, 43) positioned on a rear side of the front connection member with respect to the process proceeding direction. A distance between the front connection member and the rear connection member can be changed.
