Electric Tool Air Outlet Switching for Dust Removal and Attachment Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric tools face inefficiencies in dust removal and difficulty in accessing auxiliary tools for attachment installation, particularly when working in confined or remote locations, leading to reduced safety and productivity.
Innovation Solution
The electric tool design incorporates a rotating switching member with multiple air outlets that can be directed to optimize dust removal and a mounting mechanism for the switching member, along with a locking system for easy attachment installation, allowing for efficient airflow direction and tool operation in various environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a blowing structure is set up at the front end of the electric tool to blow away dust, then user safety is improved by avoiding contact with dust, but the blowing efficiency is low and dust in all directions cannot be effectively blown away
Solution Approach 1:
The blowing structure is divided into multiple air outlets (first air outlet at the front end and second air outlet at the side surface) that can be independently controlled. The switching member segments the airflow into different directions, allowing dust to be blown away in multiple directions simultaneously, thereby improving dust removal efficiency while maintaining user safety.
Solution Approach 2:
The air outlets are made dynamically switchable through the rotating switching member. By rotating the switching member, the airflow direction can be dynamically adjusted between the first air outlet and the second air outlet, enabling adaptive dust removal based on different working conditions and improving overall blowing efficiency.
2Reliability
If an auxiliary tool is kept in a toolbox or on a workbench for unlocking the locking member, then the locking function is reliable, but the user cannot easily access the auxiliary tool when working at height or in remote locations, reducing work efficiency
Solution Approach 1:
The auxiliary tool (wrench) is merged with the electric tool body by being stored in a dedicated storage space within the housing. This integration ensures the auxiliary tool is always available with the tool, eliminating the need to carry separate tools or search for them in toolboxes, thereby improving ease of operation while maintaining reliable locking functionality.
Solution Approach 2:
The electric tool provides its own auxiliary tool for unlocking the locking member, making the system self-sufficient. The user does not need external tools or assistance to operate the locking mechanism, enabling independent and efficient work at height or in remote locations.
3Ease of operation
If the auxiliary tool is placed on the workbench for easy access, then the user can conveniently use it, but the user may forget the placement position when using the tool next time, reducing work efficiency
Solution Approach 1:
The auxiliary tool is permanently integrated into the electric tool body through a dedicated storage space. This eliminates the need to remember placement positions on workbenches, as the tool is always in the same location - within the electric tool itself - thereby eliminating time loss while maintaining ease of operation.

AI summary
An electric tool includes a housing, a motor, a power output assembly, and a switching member. The housing is provided with a first air outlet and a second air outlet. The power output assembly is connected to the motor. The switching member is capable of rotating in the housing, and the switching member is provided with a third air outlet and a fourth air outlet. The switching member is capable of rotating to a first position and a second position in the housing. When the switching member rotates to the first position, the first air outlet is in communication with the third air outlet and the fourth air outlet is closed by the housing. When the switching member rotates to the second position, the second air outlet is in communication with the fourth air outlet and the third air outlet is closed by the housing.
