Solution Overview
Problem
Existing hand-held power tools lack an efficient and flexible material collection system that can adapt to different tools and workpieces, often resulting in restricted operation and maintenance issues due to inadequate material removal and collection mechanisms.
Innovation Solution
A material collection device with a cylindrical or cuboid container mounted on the tool via a channel element that connects to the tool's ejection port, featuring a unique adapter housing and fastening system, allowing for adjustable positioning and easy detachment, and an air-permeable filter layer for effective dust and debris collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a material collection container is mounted on a hand-held power tool, then material removal and collection capability is improved, but device complexity and space constraints worsen
Solution Approach 1:
The material collection container is nested within the housing structure of the hand-held power tool, with the container positioned inside the housing and the housing serving as the outer shell. This nesting arrangement allows the collection system to be integrated into the existing tool structure without adding external bulk, thereby improving material collection capability while minimizing the increase in device complexity and space occupation.
Solution Approach 2:
The housing structure serves multiple functions: it protects internal components, provides structural support, and simultaneously acts as the material collection container. This multi-functionality eliminates the need for separate dedicated collection components, reducing device complexity while maintaining effective material collection capability.
2Productivity
If a material collection container is mounted on a hand-held power tool, then material collection efficiency is improved, but weight and portability worsen
Solution Approach 1:
The material collection container is formed as a thin-walled structure with a filter layer, allowing it to provide effective material collection while minimizing the amount of material used. The thin-film construction reduces the weight of the container significantly compared to traditional rigid collection systems, thereby improving collection efficiency while maintaining portability and reducing overall tool weight.
Solution Approach 2:
The container incorporates a filter layer with porous structure that allows air and material particles to pass through while trapping collected material. This porous design provides effective filtration and collection functionality using minimal material, reducing the weight penalty associated with material collection systems while maintaining high collection efficiency.
3Productivity
If a filter layer is added for dust collection, then material collection effectiveness is improved, but device complexity and maintenance requirements worsen
Solution Approach 1:
The filter layer is merged with the container structure itself, forming an integrated component where the filter serves as both the collection medium and part of the container wall. This integration eliminates the need for separate filter assemblies and mounting mechanisms, reducing device complexity while maintaining effective dust and material collection capability.
Solution Approach 2:
The filter layer is designed to be easily removable and replaceable by the user without requiring specialized tools or complex disassembly procedures. The self-service design allows operators to maintain the collection system independently, reducing the need for professional maintenance and simplifying the overall system while ensuring continuous effective operation.
