Integrated Vacuum Accessory Assembly With Rotating Cleaning Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vacuum cleaners require separate attachments for different cleaning tasks, such as crevices, dusting, and upholstery, which can be inconvenient and reduce efficiency due to the need for frequent attachment changes and limited adjustability.
Innovation Solution
An integrated accessory assembly with a Crevice, Dusting, and Upholstery, where the Upholstery is rotatably coupled and the Crevice is rotatably adjustable, allowing for efficient cleaning of various surfaces without the need for constant attachment changes, and an adjustable Dusting mechanism for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate attachments are used for different cleaning tasks, then each attachment can be optimized for its specific function, but the device complexity increases and requires frequent attachment changes
Solution Approach 1:
The patent combines multiple separate attachments (crevice tool, dusting brush, upholstery brush) into a single integrated accessory assembly. The crevice tool, dusting brush, and upholstery brush are all mounted on one handle pipe, allowing users to switch between different cleaning functions by simply rotating or adjusting the position of different tools on the same assembly, rather than detaching and reattaching separate attachments.
Solution Approach 2:
The accessory assembly is designed as a universal cleaning device that can perform multiple cleaning functions simultaneously. The handle pipe can accommodate different types of attachments (crevice tool for narrow spaces, dusting brush for surfaces, upholstery brush for fabrics) on a single platform, making one device capable of replacing multiple specialized attachments.
2Adaptability or versatility
If separate attachments are used for different cleaning tasks, then each attachment can be optimized for its specific function, but the loss of time increases due to frequent attachment changes
Solution Approach 1:
The patent combines multiple separate attachments (crevice tool, dusting brush, upholstery brush) into a single integrated accessory assembly. The crevice tool, dusting brush, and upholstery brush are all mounted on one handle pipe, allowing users to switch between different cleaning functions by simply rotating or adjusting the position of different tools on the same assembly, rather than detaching and reattaching separate attachments.
3Device complexity
If the Upholstery is fixed on the accessory body, then the structure is simpler, but the adaptability to different surfaces is reduced
Solution Approach 1:
The upholstery brush is designed with rotational freedom, allowing it to rotate relative to the accessory body. This dynamic capability enables the brush to adapt to different surface geometries and cleaning angles, improving versatility without significantly complicating the overall structure. The rotation mechanism allows the brush to reach different areas and adjust to varying surface contours.
4Device complexity
If the Crevice is fixed on the accessory body, then the structure is simpler, but the adaptability to different gaps and angles is reduced
Solution Approach 1:
The crevice tool is designed with rotational freedom, allowing it to rotate relative to the accessory body. This dynamic capability enables the crevice tool to access different angles and orientations of gaps and narrow spaces, improving adaptability without significantly complicating the overall structure. The rotation mechanism allows the crevice tool to reach different areas and adjust to varying gap orientations.

AI summary
A cleaner comprises a body configured to generate a suction force, a handle including a first manipulation part configured to select a function of the cleaner, an extension pipe detachably coupled to the handle and an accessory assembly configured to be coupled to the handle to clean a cleaning surface. The accessory assembly comprises an accessory body, a dusting tool on which a brush is mounted, a crevice tool to clean a gap, and an Upholstery tool to clean fabrics. The upholstery tool is rotatably coupled to the accessory body, the crevice tool is rotatably coupled to the accessory body so that a suction port of the crevice tool is rotatable with respect to the accessory body, and a central axis of the accessory body is provided to be inclined at a predetermined angle with respect to a rotation axis of the crevice tool.
