Vacuum Cleaner Suction Nozzle Angle-Based Fastening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in efficiently separating and storing suction nozzles, leading to inconvenience and potential loss during use and storage.
Innovation Solution
A vacuum cleaner design featuring a suction nozzle and connection pipe that can be easily separated and reconfigured, with a mechanism allowing the connection pipe to remain fastened or released based on the relative angle between the nozzle and pipe, enabling convenient handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the suction nozzle and connection pipe are permanently coupled, then the structural stability is improved, but the ease of operation deteriorates due to inability to separate for storage
Solution Approach 1:
The connection structure is divided into separable components: the connection pipe includes a first connection portion with a catching groove, and the suction nozzle includes a second connection portion with a catching protrusion. These segmented parts can be coupled together during use and separated during storage, resolving the contradiction between structural stability and ease of separation.
2Reliability
If the suction nozzle and connection pipe are permanently coupled, then the reliability is improved, but the ease of operation deteriorates due to inconvenience in storage
Solution Approach 1:
The connection between the suction nozzle and connection pipe is made dynamic rather than static. The elastic body enables the connection to transition between coupled and separated states, allowing the system to adapt between reliability during use and ease of storage during non-use periods.
3Ease of operation
If the connection pipe is made detachable, then the ease of operation is improved for storage, but the reliability deteriorates due to potential loss
Solution Approach 1:
The elastic body is pre-configured in the connection structure to provide automatic retention force. This beforehand cushioning mechanism ensures that the suction nozzle and connection pipe remain securely coupled during use, preventing loss while still allowing intentional separation for storage.
4Ease of operation
If the connection mechanism is made simple for easy separation, then the ease of operation is improved, but the strength deteriorates due to weaker connection
Solution Approach 1:
The elastic body automatically engages the catching protrusion with the catching groove without requiring additional fastening operations. This self-service mechanism provides strong connection strength while maintaining ease of separation, as the user simply needs to overcome the elastic retention force to detach the components.

AI summary
A vacuum cleaner includes a cleaner body, a connection pipe including a first catching groove, and a suction nozzle. The suction nozzle includes a connection neck, a nozzle housing rotatably coupled to the connection neck, a first catching body rotatably coupled to the connection neck, and a first elastic body. The first catching body includes a first catching protrusion portion which is caught by the first catching groove. The suction nozzle includes a pressing portion and a first lever. The first lever includes a first end portion in contact with the pressing portion, and a second end portion configured to press the first catching body. According to the disclosed vacuum cleaner, the fastening between the suction nozzle and the connection pipe may be maintained or released according to the relative angle between the suction nozzle and the connection pipe.
