Swiveling Shroud Extraction Coupling for Compact Slurry Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction apparatuses for controlling slurry and debris during masonry operations, such as cutting and chasing, face challenges in maintaining a compact arrangement due to the need for flexible tube connections that flex and occupy space as the shroud swivels, leading to inefficiencies in containing and collecting the slurry effectively.
Innovation Solution
A slidable coupling system between the shroud and the suction source is introduced, allowing for a telescopic fluid flow path that accommodates angular movement, eliminating the need for a separate flexible tube and enabling compact packaging by allowing the shroud to swivel independently while maintaining effective slurry collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible tube section is used to connect the shroud and suction line to accommodate swiveling movement, then the shroud can swivel freely, but the flexible tube flexes and occupies space adjacent the shroud which is inconvenient and prevents compact arrangement
Solution Approach 1:
The patent merges the flexible tube with the rigid suction line by providing a recess in the suction line that receives the flexible tube. This integration allows the flexible tube to be stored within the suction line structure itself, eliminating the need for separate flexible tube storage space adjacent to the shroud while maintaining full swiveling capability.
Solution Approach 2:
The flexible tube is nested within the suction line structure through the recess arrangement. When the shroud swivels, the flexible tube can be stored within the recess of the suction line, creating a compact nested configuration that eliminates external space occupation while preserving movement freedom.
2Adaptability or versatility
If the flexible tube section is made long enough to accommodate full swiveling movement, then the shroud can achieve full range of motion, but the surplus portion of the flexible tube flexes and occupies space which is generally inconvenient
Solution Approach 1:
By integrating the flexible tube storage function into the suction line structure through the recess, the patent eliminates the need for separate management of surplus flexible tube. The recess provides a dedicated storage location that keeps the flexible tube organized and out of the way throughout the full range of motion.
3Adaptability or versatility
If the shroud is mounted for swiveling movement on the machine, then the shroud can maintain correct alignment with the surface during angular movement, but a connection must accommodate both swiveling movement and slurry collection path
Solution Approach 1:
The patent combines the movement accommodation function and slurry collection function into a single integrated connection structure. The recess in the suction line serves both to store the flexible tube during swiveling and to maintain the slurry collection path, eliminating the need for separate mechanisms for each function.

AI summary
An extraction apparatus (20) for a cutting machine (10). The extraction apparatus (20) comprises first and second portions (21, 22) rotatable one relative to the other for angular movement between two opposed positions. A slidable coupling (27) defines a fluid flow path (29) for fluid communication between the first and second portions (21, 22) during said angular movement between the two opposed positions, whereby fluid can flow from the interior (45) of the first portion (21 ) into the second portion (22). The slidable coupling (27) comprises first and second coupling sections (61, 62) slidable one with respect to the other. The second coupling section (62) is hollow to define an open interior (63). The first coupling section (61 ) defines a duct (65) opening onto the interior (63) of the second coupling section (62), whereby the duct (65) and the interior (63) of the second coupling section (62) cooperate to define the fluid flow path (29).
