Upright Vacuum Cleaner Joint Structure for Easier Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright type vacuum cleaners suffer from poor steering performance and user fatigue due to direct load pressure on the suction nozzle and integrated design, making it difficult to maintain cleaning for extended periods.
Innovation Solution
A joint system connecting the main body and suction nozzle allows for rotation about multiple axes, combined with a support unit to distribute the load, enabling variable disposition angles and reduced user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the main body is integrated with the suction nozzle, then the structure is simplified, but the steering performance is lowered
Solution Approach 1:
The vacuum cleaner is divided into separate functional modules: the main body and the suction nozzle are disconnected, with the suction nozzle becoming a detachable component. This segmentation allows the main body to be supported independently while the suction nozzle can be freely positioned and steered, resolving the contradiction between structural simplicity and steering performance.
2Shape
If the main body is located at the upper part of the suction nozzle, then the upright structure is maintained, but load pressure is directly applied to the suction nozzle
Solution Approach 1:
A support unit is introduced as an intermediary component between the main body and the suction nozzle. This support unit includes a support rod that extends downward to contact the floor, transferring the load pressure from the main body to the floor rather than to the suction nozzle. This allows the upright structure to be maintained while eliminating the harmful load transfer.
3Device complexity
If the suction nozzle is integrated with the main body, then the design is compact, but load pressure rotated at a predetermined angle is applied to the user
Solution Approach 1:
The integrated design is segmented into separate components with independent functions. The suction nozzle is detached from the main body and can be freely positioned, while the main body's orientation is controlled independently through the support unit. This eliminates the transmission of rotational load pressure to the user, reducing fatigue while maintaining design compactness.
4Adaptability or versatility
If the dust collection box and suction motor are mounted in the main body, then the suction function is integrated, but the user must support the load of the main body
Solution Approach 1:
The support unit acts as an intermediary that bears the weight of the main body containing the dust collection box and suction motor. By providing this external support structure that contacts the floor, the user is relieved of the burden of supporting the main body's load, while the integrated suction function remains intact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves steering performance and user convenience by allowing easier maneuverability and reduced fatigue during prolonged cleaning sessions.
Implementation Method 1
when the suction motor is driven by power supplied to the main body, suction force is generated by the suction motor, and air containing dust and foreign matter is suctioned into the suction nozzle by the suction force
Implementation Method 2
In a dust collection box mounted in the main body, the dust and foreign matter are separated from the air according to the principle of cyclone

AI summary
An upright type vacuum cleaner is disclosed. The upright type vacuum cleaner includes a main body provided so that a disposition angle of the main body with respect to a surface to be cleaned is variable, a suction nozzle coupled to the main body so that the suction nozzle moves along the surface to be cleaned, and a joint provided between the main body and the suction nozzle to connect the main body and the suction nozzle so that the main body and the suction nozzle are rotated about a plurality of axes.
