Enhanced Steering for Upright Vacuum Cleaners
Here’s PatSnap Eureka !
Summary
Problems
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 for users to maintain cleaning for extended periods.
Innovation solutions
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 angle adjustment and reduced user effort during cleaning.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the main body is integrated with the suction nozzle, then the structure is simplified, but the steering performance is lowered
Why choose this principle:
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.
Principle concept:
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
Why choose this principle:
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.

Abstract
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.
