Attachment-Aware Work Tool Control for Dust Collector Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work tools face inefficiencies due to poor cooperation between the tool main body and attached devices, leading to reduced working efficiency and increased power consumption.
Innovation Solution
A work tool with a controller that detects the connection of an attachment device and adjusts its control accordingly, activating or deactivating assisting means such as lighting and adjusting motor speed and power supply based on the connection state, ensuring optimal operation whether the attachment device is present or not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the main body operates with full power and all assisting means activated regardless of attachment device connection, then the main body can perform work independently, but power consumption increases and working efficiency deteriorates when attachment device is connected
Solution Approach 1:
The controller dynamically adjusts the operating state of the main body and assisting means based on the connection status of the attachment device. When the attachment device is connected, the controller modifies motor speed, power supply, and activates/deactivates assisting means appropriately, transforming the system from a static to a dynamic control mode that adapts to operational conditions
Solution Approach 2:
The controller detects whether the attachment device is connected and uses this feedback information to adjust the control strategy. The detection mechanism provides real-time status information to the controller, which then modifies operational parameters accordingly, creating a closed-loop control system that responds to connection status changes

3Ease of operation
If assisting means is always activated during work, then work can be performed with full assistance, but power consumption increases and working efficiency deteriorates when attachment device is connected
Solution Approach 1:
The controller dynamically adjusts the operating state of the main body and assisting means based on the connection status of the attachment device. When the attachment device is connected, the controller modifies motor speed, power supply, and activates/deactivates assisting means appropriately, transforming the system from a static to a dynamic control mode that adapts to operational conditions

AI summary
Provided is a work tool that can work suitably in cooperation with an attachment device connected to a main body of the work tool to enhance work efficiency. The work tool includes a main body 2, and a control circuit 71 configured to provide control over the main body 2. The main body 2 includes a motor 3, an end-bit mount portion 10 and an end bit 14 as a work part configured to be driven by the motor 3 to perform a work. A dust collector 100 is connectable to the main body 2 to assist the work. The control circuit 71 is configured to detect whether the dust collector 100 is connected to the main body 2 and change the control over the main body 2 based on whether the connection is established or not.
