Sanding Block with Integrated Battery-Powered Dust Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual sanding tools lack efficient dust extraction capabilities, leading to environmental contamination and the need for external vacuum devices, which hinder usability and increase weight imbalance.
Innovation Solution
Integration of a battery-operated dust extraction system within the sanding block, featuring a motor housing with a fan wheel, rechargeable battery, and a detachable dust box, allowing for mains-independent operation and direct dust collection at the source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual sanding is performed without integrated dust extraction, then the tool remains simple and lightweight, but dust disperses into the environment causing contamination
Solution Approach 1:
The patent combines the sanding function and dust extraction function into a single integrated tool. The sanding block includes a base plate for holding abrasive articles and a housing containing a battery-operated dust extraction device with a fan wheel, dust container, and suction openings. This merging eliminates the need for separate external vacuum equipment while capturing dust at the source during sanding operations.
2Object-affected harmful factors
If external vacuum equipment is used for dust extraction, then dust can be captured, but usability is hindered and weight distribution becomes unbalanced
Solution Approach 1:
The dust extraction device is integrated directly into the sanding block housing, combining both functions in one handheld tool. This eliminates the need for separate external vacuum equipment and hoses, improving usability by allowing the user to operate with a single balanced tool rather than managing multiple devices.
Solution Approach 2:
The suction openings are positioned on the base plate and housing to create localized dust capture zones close to the sanding contact point. This spatial arrangement enables effective dust extraction without requiring large external vacuum units, maintaining a compact and balanced handheld design.
3Power
If mains power supply is used for dust extraction, then sufficient power can be provided, but the tool requires connection to external power sources reducing mobility
Solution Approach 1:
The sanding block is equipped with an integrated rechargeable battery pack that provides autonomous power for the dust extraction fan wheel. This self-contained power source eliminates the need for external power connections or mains supply, enabling complete portability and mobility while maintaining sufficient power for effective dust extraction during sanding operations.
