Two-Part Vacuum Attachment with Integrated Crevice and Brush Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaning appliances require time-consuming and prone-to-misplacement accessory changes between different suction tools, hindering efficient mode switching during cleaning.
Innovation Solution
A two-part attachment for vacuum cleaners featuring a crevice nozzle and a brush section that can be moved between retracted and deployed positions, allowing for quick mode changes between handheld and floor cleaning without replacing tools, with the brush section and crevice nozzle stored within the second part for protection and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If auxiliary suction tools are provided as separate accessories for interchange, then the appliance can be used in different cleaning modes, but the user may temporarily misplace or lose tools and the act of detaching and reattaching tools is time consuming
Solution Approach 1:
The patent combines multiple auxiliary suction tools (crevice tool and brush tool) into a single integrated attachment assembly that can be quickly connected to the vacuum cleaner body. This merging eliminates the need to handle multiple separate accessories, reducing the time required to switch between cleaning modes while maintaining versatility through the integrated design of the attachment.
Solution Approach 2:
The attachment assembly serves multiple functions by integrating both crevice and brush tools into one universal component. This multi-functional design allows the user to switch between different cleaning modes (crevice cleaning and surface brushing) without needing to attach separate tools, thereby reducing tool switching time while maintaining adaptability across different cleaning scenarios.
2Adaptability or versatility
If auxiliary suction tools are provided as separate accessories, then the appliance can be used in different cleaning modes, but the user may temporarily misplace or lose tools
Solution Approach 1:
By merging multiple auxiliary tools into a single integrated attachment assembly, the patent ensures that all cleaning tools are kept together as one unit. This eliminates the risk of misplacing or losing individual tools, as the entire set is attached to the vacuum cleaner body in a single connection, thereby improving tool availability while maintaining cleaning mode versatility.
3Ease of operation
If the brush section is always deployed, then surface cleaning is effective, but the crevice nozzle cannot be inserted between gaps in furniture
Solution Approach 1:
The brush section is designed to be movable relative to the crevice nozzle, allowing it to be retracted when crevice cleaning is needed and deployed when surface cleaning is required. This dynamic configuration enables the attachment to adapt between different cleaning modes, providing both effective surface cleaning and crevice access capability without compromise.
4Adaptability or versatility
If the brush section is retracted, then crevice access is possible, but surface cleaning effectiveness is reduced
Solution Approach 1:
The movable brush section allows the user to dynamically adjust the attachment configuration based on the cleaning task. When crevice access is needed, the brush is retracted; when surface cleaning is required, the brush is deployed. This dynamic adaptability ensures optimal performance for each cleaning mode without permanent compromise to either function.

AI summary
An attachment for a vacuum cleaning appliance has a first part which is connectable to a main body of the appliance, and a second part which is connectable to the first part. The first part includes a crevice nozzle and a brush section which is moveable along the crevice nozzle between a retracted position and a deployed position. The second part includes a suction inlet, and is arranged to be push-fitted over the first part so that the crevice nozzle and the brush section of the first part are both stored within the second part when the second part is connected to the first part.
