Solution Overview
Problem
Existing vacuum tools lack versatility and adaptability for various work environments, particularly in terms of coupling with hoses or wands of different dimensions and orientations, and do not effectively utilize suction force for both surface attachment and debris collection.
Innovation Solution
A vacuum tool design featuring a flexible portion with multiple apertures and a mechanical joint allowing adjustable orientations, a universal coupler for hoses of varying dimensions, and a deployable carriage with interchangeable brush elements for enhanced cleaning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid fixed-orientation tool is used, then the structure is simple and manufacturing is easy, but the tool cannot adapt to different work environments and orientations
Solution Approach 1:
The patent applies the dynamics principle by implementing a mechanical joint that enables the tool to rotate and adjust between fixed orientations (e.g., 0°, 45°, 90° angles) rather than being rigidly fixed. This allows the tool to adapt to different work environments and surface orientations while maintaining structural integrity through controlled movement mechanisms.
2Adaptability or versatility
If a universal coupler for various hose dimensions is implemented, then the adaptability to different hoses is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal coupler design that can accommodate hoses of varying dimensions and types through a single multi-functional interface. The coupler incorporates adjustable components and universal fitting mechanisms that enable connection to different hose configurations without requiring multiple specialized couplers, thereby improving versatility while controlling complexity through design integration.
3Reliability
If suction force is used for surface attachment, then the tool can be securely held to surfaces, but the force available for debris collection is reduced
Solution Approach 1:
The patent applies segmentation by dividing the tool into distinct functional zones: one or more apertures dedicated to surface attachment and separate openings for debris collection. This allows suction force to be distributed and utilized simultaneously for both holding the tool to the surface and drawing debris into the collection system, thereby maintaining attachment security while preserving debris collection productivity.

AI summary
A vacuum tool that is removably couplable to a hose or wand of a vacuum includes a body, funnel, gasket, and connection portion. The body includes a first end, second end, and wall extending between the first and second ends. The wall forms a work surface suction opening and a cavity in fluid communication with each other. The funnel includes a proximal skirt portion coupled to the first end and a distal skirt portion integrally formed with the proximal skirt portion. The proximal skirt portion has an aperture in fluid communication with the cavity. The distal skirt portion extends from the proximal skirt portion in a direction away from the first and second ends. The gasket is positioned along a perimeter of the work surface suction opening. The connection portion is coupled to the second end and includes a conduit in fluid communication with the cavity and an outlet.
