Suction Hose Joint Attachment for Ergonomic Dust Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction-extraction systems for handheld power tools are inefficient in ergonomics and suction performance due to rigid connections and lack of mobility, leading to reduced effectiveness in extracting drilling cuttings and dust directly at the point of use.
Innovation Solution
A suction-extraction aid with a joint unit that allows for movable connection to the housing, providing rotational degrees of freedom and a detachable design, coupled with a fastening device for flexible hose attachment, enhances ergonomics and suction efficiency by allowing the suction hose to be positioned optimally relative to the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used between the suction-extraction aid and the housing, then structural stability is improved, but ergonomics and flexibility are worsened
Solution Approach 1:
The joint unit enables dynamic positioning of the suction hose relative to the housing, allowing the hose to be adjusted to optimal angles during operation. This resolves the contradiction by providing both structural connection (stability) and operational flexibility (ergonomics) through movable articulation points.
2Stability of the object's composition
If a rigid connection is used between the suction-extraction aid and the housing, then structural stability is improved, but suction performance is worsened
Solution Approach 1:
The joint unit enables dynamic positioning of the suction hose relative to the housing, allowing the hose to be adjusted to optimal angles during operation. This resolves the contradiction by providing both structural connection (stability) and operational flexibility (ergonomics) through movable articulation points.
3Device complexity
If a fixed non-detachable design is used, then device complexity is reduced, but adaptability is worsened
Solution Approach 1:
The suction-extraction aid is designed as a detachable module that can be connected to and disconnected from the housing. This segmentation allows the system to maintain simplicity when not in use while providing adaptability when needed, resolving the contradiction between device complexity and adaptability.
4Ease of operation
If the suction hose is positioned far from the workpiece, then ease of operation is improved, but suction performance is worsened
Solution Approach 1:
The joint unit enables dynamic positioning of the suction hose relative to the housing, allowing the hose to be adjusted to optimal angles during operation. This resolves the contradiction by providing both structural connection (stability) and operational flexibility (ergonomics) through movable articulation points.
