Vacuum Cleaner Connection Pipe with Integrated Rotating Nozzle Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners lack a convenient and efficient mechanism for transitioning between suction nozzles, leading to inconvenience in storage and potential loss of nozzles during use.
Innovation Solution
A vacuum cleaner design featuring a connection pipe with a movable body, first rotating body, and second rotating body that form a second suction port when the primary suction nozzle is detached, allowing for automatic nozzle switching and stable operation without additional nozzle attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple suction nozzles are provided for different cleaning purposes, then cleaning versatility is improved, but storage convenience deteriorates and risk of loss increases
Solution Approach 1:
The connection pipe is designed to serve multiple functions: it acts as both a connection component and a storage container for spare nozzles. The internal cavity of the connection pipe provides storage space, while the external connection structure maintains its primary function. This multi-functionality resolves the contradiction by eliminating the need for separate storage solutions.
Solution Approach 2:
The suction nozzles are stored inside the connection pipe, creating a nested structure where one component (nozzle) is placed within another (connection pipe). This nesting arrangement provides compact storage for multiple nozzles without increasing the overall device footprint, directly addressing the storage convenience issue.
2Adaptability or versatility
If multiple suction nozzles are provided for different cleaning purposes, then cleaning versatility is improved, but device complexity increases
Solution Approach 1:
The connection pipe serves dual purposes as both a connection mechanism and a storage container. This eliminates the need for additional separate storage components, thereby maintaining device simplicity while enabling multi-nozzle functionality.
Solution Approach 2:
The storage function is merged with the connection pipe structure itself. By combining what would traditionally be separate components (connection pipe and storage container) into a single integrated structure, the device complexity is minimized while still providing versatile nozzle storage.
3Adaptability or versatility
If suction nozzles need to be detached and reattached frequently, then adaptability is improved, but time consumption increases
Solution Approach 1:
Spare nozzles are pre-stored inside the connection pipe, ready for immediate use. When nozzle replacement is needed, users only need to attach the pre-positioned nozzle from the storage cavity rather than searching for or transporting separate storage containers. This preliminary positioning of nozzles significantly reduces the time required for nozzle replacement.

AI summary
A vacuum cleaner includes a connection pipe, a cleaner body, a suction nozzle having a first suction port, a movable body, a first rotating body, and a second rotating body. The movable body is movably coupled to the connection pipe, and the first rotating body and the second rotating body are rotatably coupled to the movable body. According to the disclosed vacuum cleaner, in a state in which the connection pipe is separated from the suction nozzle, the first rotating body and the second rotating body may form a second suction port, and may form a nozzle other than the suction nozzle.
