Solution Overview

Problem

Existing hand-held power tools lack an efficient and flexible material collection system that can accommodate different discharge nozzles and operate without restricting the tool's maneuverability, especially when working on uneven or confined surfaces.

Innovation Solution

A material collection device with a cylindrical or cuboid container and a channel element that can be rotated and pivoted relative to the tool, featuring a unique angle configuration with the discharge nozzle to minimize interference and allow for flexible positioning, along with an adapter housing that accommodates various nozzles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a material collection container is mounted on a hand-held power tool with a discharge nozzle, then material collection efficiency is improved, but the tool's maneuverability and ease of operation deteriorates due to interference and restricted positioning

Engineering Contradiction:
Improvematerial collection efficiencyVSAvoidtool maneuverability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The mounting unit incorporates a pivoting mechanism that allows the material collection container to be rotated and tilted relative to the discharge nozzle. This dynamic positioning capability enables the container to adapt to different working angles and surfaces, maintaining material collection efficiency while avoiding interference with the tool's operation and improving maneuverability in confined spaces

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a fixed mounting arrangement is used for the material collection container, then device complexity is reduced, but adaptability to different discharge nozzles and working conditions deteriorates

Engineering Contradiction:
Improvemounting structure simplicityVSAvoidaccommodation of different discharge nozzles
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The mounting unit provides adjustable positioning through pivoting and tilting mechanisms, allowing adaptation to different discharge nozzle orientations and working conditions without requiring complex custom mounting solutions for each scenario

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting unit is designed with universal adaptability to accommodate different discharge nozzles and working conditions through its adjustable positioning capabilities, making it applicable across various tool configurations and applications

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a material collection device for a hand-held power tool, comprising a material collection container (112a) for collecting material removed during operation of the hand-held power tool, wherein at least one opening (120a) of the material collection container (112a) is arranged in an opening plane (122a) for feeding the material into the material collection container (112a) and comprising at least one mounting unit (124a) for mounting the material collection container (112a) on the hand-held power tool. It is proposed that the assembly unit (124a) comprises a channel element (126a) for connection with a discharge nozzle (76a; 76b; 76c; 76d) of the hand-held machine tool, wherein a longitudinal channel axis (84a) of the channel element (126a) is arranged in at least one section plane perpendicular to the opening plane (122a) and transverse to the opening plane (122a) of the material collection container (112a).
