Power Tool Dust Collection Control for Weight and Orientation Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collecting systems for power tools lack efficient control mechanisms to adapt to varying weights and orientations, leading to inconsistent dust collection performance.
Innovation Solution
A dust collecting system with a power tool and a dust collector, featuring a control device that adjusts the operation of both based on the weight of the batteries and the dust collector, using sensors to determine optimal rotation speeds for the dust collection motor, ensuring effective dust collection across different operational conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dust collector is attached to a power tool to collect dust generated by processing operations, then dust collection capability is improved, but the overall weight of the system increases
Solution Approach 1:
The control device dynamically adjusts the rotation speed of the dust collection motor based on the detected overall weight of the power tool system. When the system detects a heavier configuration (power tool plus dust collector), it automatically optimizes motor speed to maintain effective dust collection while accounting for the increased weight, thereby resolving the contradiction between dust collection capability and system weight
2Adaptability or versatility
If the dust collector is removably attached to adapt to different operational conditions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control device automatically detects whether the dust collector is attached and self-adjusts the dust collection motor speed without requiring manual intervention. The system weighs itself to determine the overall weight and autonomously optimizes operational parameters, thereby achieving adaptability while minimizing the complexity of user interaction and control system design

AI summary
A dust collecting system includes a power tool and a dust collector. The power tool includes at least one battery-mounting part, a first motor, a driving mechanism and a body housing. The at least one battery-mounting part is each configured to removably receive a battery. The first motor is configured to operate with electric power supplied from the battery. The driving mechanism is configured to drive the tool accessory by power of the first motor. The body housing houses the first motor and the driving mechanism. The dust collecting system includes a control device configured to control operation of at least one of the power tool and the dust collector according to a state of the whole dust collecting system.
