Universal Tool Handle Interface for Electrical and Manual Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing devices require separate handles for electrical and non-electrical tools, leading to space inefficiency, high costs, and the need to carry multiple handles, as electrical tools cannot be connected to non-electrical handles and vice versa.
Innovation Solution
A processing device with a handling device featuring a connecting portion that allows both mechanical and electrical connections, enabling the use of either electrical or non-electrical tools with a single handle, utilizing a socket with plug-in and snap-fit mechanisms for secure and quick tool attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate handles are used for electrical and non-electrical tools, then reliable connection is achieved, but device complexity and storage space requirements increase
Solution Approach 1:
The handling device is designed with a universal connecting portion that can accommodate both electrical tools and non-electrical tools through a single interface. The connecting portion includes electrical contacts that can establish electrical connection when an electrical tool is attached, while also providing mechanical connection for non-electrical tools, thereby eliminating the need for separate handles and reducing device complexity
2Adaptability or versatility
If multiple handles are kept for different tools, then compatibility is ensured, but storage space and costs increase
Solution Approach 1:
A single handling device with a universal connecting portion is designed to accommodate both electrical and non-electrical tools. The connecting portion includes electrical contacts that can establish electrical connection when an electrical tool is attached, while also providing mechanical connection for non-electrical tools, thereby eliminating the need for separate handles and reducing storage space requirements
3Loss of energy
If electrical contacts are integrated in the connecting portion, then power supply efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The electrical contacts are integrated directly into the connecting portion of the handling device, merging the electrical connection function with the mechanical connection function. This integration eliminates the need for separate electrical connection components and reduces the number of assembly steps, thereby reducing power loss while actually simplifying the manufacturing process
