Integrated Power Tool Dust Collection With Retractable Dust Tube

Solution Overview

Problem

Existing dust collection systems for power tools are often bulky, separate from the tool, and increase the overall cost and weight of the tool system, limiting maneuverability and requiring duplicate parts.

Innovation Solution

Integration of a dust collection assembly within the power tool, sharing components like the motor and fan, reducing the number of parts, weight, and cost, while maintaining a compact profile for easier handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a separate dust collection system is used with the power tool, then dust collection effectiveness is improved, but the overall weight and bulk of the tool system increases

Engineering Contradiction:

Improvedust collection effectivenessVSAvoidtool system weight

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The dust collection system is merged with the power tool by integrating the dust container into the tool housing and sharing the motor between the drive assembly and the dust collection fan, creating a unified tool system that collects dust without requiring a separate external collection device

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The motor serves dual functions by powering both the drive assembly that operates the tool accessory and the dust collection fan that generates suction for dust collection, allowing one component to perform multiple roles and reducing overall system weight

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If a separate dust collection system is used with the power tool, then dust collection effectiveness is improved, but the overall cost increases

Engineering Contradiction:

3Object-affected harmful factors

If a separate dust collection system is used with the power tool, then dust collection effectiveness is improved, but the device complexity increases

Engineering Contradiction:

Improvedust collection effectivenessVSAvoidnumber of parts

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The dust collection system is merged with the power tool by integrating the dust container into the tool housing and sharing the motor between the drive assembly and the dust collection fan, creating a unified tool system that collects dust without requiring a separate external collection device

4Object-affected harmful factors

If a separate dust collection system is used with the power tool, then dust collection effectiveness is improved, but the overall length increases

Engineering Contradiction:

Improvedust collection effectivenessVSAvoidtool system length

Core Design Contradiction:

Object-affected harmful factorsVSLength of moving object

Solution Approach 1:

The dust container is nested within the tool housing, with the container positioned inside the hollow housing structure, allowing the dust collection system to occupy space within the existing tool envelope rather than extending the overall tool length

Inventive Principle:

Principle #7Nested doll (Nesting)
