Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust couplers require multiple types to fit different woodworking machines, increasing costs through purchase, assembly, and maintenance, and are cumbersome to clean.
Innovation Solution
A dust coupler with a hollow collecting pipe connector and an elastic sheathing element that can be elastically attached to dust outlet tubes of varying sizes, allowing a single coupler to connect with any woodworking machine without the need for multiple types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of conventional dust couplers are prepared for different woodworking machines, then each dust outlet tube can be properly connected, but the cost of purchase, assembly, and maintenance increases significantly
Solution Approach 1:
The patent applies universality by designing a single dust coupler that can connect to dust outlet tubes of multiple different sizes. The coupler includes an elastic sealing ring that can be elastically deformed to adapt to different tube diameters, eliminating the need for multiple specialized couplers for different machine types.
Solution Approach 2:
The patent uses parameter changes by making the sealing ring elastic and deformable. The sealing ring's diameter can be dynamically adjusted through elastic deformation to match different dust outlet tube sizes, allowing one coupler design to serve multiple size requirements.
2Adaptability or versatility
If multiple types of conventional dust couplers are prepared for different woodworking machines, then proper connection is achieved, but the time and effort required for assembly and cleaning increases
Solution Approach 1:
The universal dust coupler design allows workers to use the same coupler type for all woodworking machines regardless of tube size variations, eliminating the need to select and assemble different coupler types for different machines, thereby reducing assembly time and simplifying maintenance routines.
3Reliability
If conventional dust couplers are used for different woodworking machines, then dust collection is effective, but cleaning and maintenance costs increase
Solution Approach 1:
The universal coupler design means that spare parts inventory is simplified and maintenance personnel only need to be trained on one coupler type. Cleaning procedures are standardized across all machines, reducing the complexity and cost of maintenance operations while maintaining effective dust collection.

AI summary
A dust coupler adapted to different dust outlet tubes has a collecting pipe connector and an elastic sheathing element. The collecting pipe connector has a first end and a second end being opposite to each other. The first end is configured to be inserted into a collecting pipe of a dust collection system for woodworking. The elastic sheathing element is connected to the second end of the collecting pipe connector, has a mouth, and is configured to be elastically sheathed onto a dust outlet tube of a woodworking machine. A woodworker first mounts the dust coupler on the collecting pipe, and the collecting pipe can be combined with any one of different dust outlet tubes of different woodworking machines having different sizes via the dust coupler. The dust coupler allows the collecting pipe to be quickly combined with or detached from the dust outlet tube.
