Deformable Adapter for Cordless Vacuum Cleaner Accessory Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless electric brooms face difficulties in connecting accessories or flexible tubes due to unconventional shapes and sizes of their motor units, making it impractical to use in narrow environments or for tasks like pet grooming, and standard hoses cannot be easily attached.
Innovation Solution
An adapter device with a hollow tubular body made of deformable material, featuring a cylindrical first end and a conical second end with multiple taper sections and radial sealing rings, allowing it to engage both the vacuum cleaner and accessories or hoses, adapting to various shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless electric brooms have fixed rigid tube connections, then structural simplicity and manufacturing ease are improved, but flexibility in reaching narrow environments and diverse surfaces deteriorates
Solution Approach 1:
The patent employs flexible tubes instead of rigid tube connections. The flexible tube can be bent and shaped to reach narrow environments, furniture, vehicles, and diverse surfaces while maintaining the structural simplicity of the overall system. The flexibility allows the tube to adapt to various geometries without complicating the manufacturing process.
2Adaptability or versatility
If standard hoses are used with non-standard vacuum cleaner tubes, then accessory availability and user choice are improved, but connection reliability and sealing performance deteriorate
Solution Approach 1:
The adapter incorporates sealing elements at specific locations where connections are made. The sealing features are localized to the interface areas between the adapter and both the vacuum cleaner motor unit and the standard accessories. This local quality approach ensures reliable sealing at critical connection points while maintaining the overall simplicity of the adapter design.
