Power Tool Handling Device Guide Groove Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools, such as grass shears, are complex to handle and difficult to guide through handling devices, making it challenging for users to connect and control them effectively.
Innovation Solution
The arrangement features a guide groove and projection system that allows easy insertion and secure mounting of the power tool onto a handling device, with a locking element ensuring firm connection, and a pivoting mechanism that allows precise control and adjustment of the power tool's angle relative to the plane of support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing handling devices are used to support and move the power tool, then the power tool can be moved on a plane, but the connection between the handling device and the power tool is complex and difficult to establish
Solution Approach 1:
The connection system is divided into separate functional elements: guide grooves on the power tool housing, corresponding guide projections on the handling device, and a locking mechanism with locking protrusions and recesses. This segmentation allows each element to perform its specific function independently, simplifying the overall connection process while maintaining security.
Solution Approach 2:
The guide grooves and guide projections act as intermediary elements that facilitate the alignment and insertion of the power tool into the handling device. These guide elements mediate the connection process by providing a predetermined path that automatically aligns the locking elements, making the connection simple and intuitive even for inexperienced users.
2Reliability
If the power tool is securely mounted on the handling device, then precise control is achieved, but the connection mechanism becomes more complex
Solution Approach 1:
The guide function and locking function are merged into a single integrated connection mechanism. The guide grooves and projections not only align the components but also work together with the locking protrusions and recesses to secure the mounting in one unified action, eliminating the need for separate alignment and locking steps.
Solution Approach 2:
The connection mechanism is designed to be self-aligning and self-locking. When the power tool is inserted into the handling device, the guide projections automatically follow the guide grooves into the correct position, and the locking protrusions automatically engage with the locking recesses without requiring additional manual intervention, ensuring secure mounting through the user's own insertion action.
3Measurement precision
If the guide rod is positioned at a steep angle (60°-90°) to the plane, then precise control and small reduction ratio are achieved, but the attachment point location becomes more restricted
Solution Approach 1:
The connection mechanism is designed with localized guide grooves and projections at specific positions on the power tool housing and handling device. This local optimization allows the guide rod to be positioned at the optimal steep angle for precision control at the specific attachment point, while the overall system remains adaptable through the universal receptacle design that can accommodate different power tool configurations.
