Upright vacuum cleaner having a support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright vacuum cleaners are typically bulky due to the need for long supports to maintain an upright self-standing position, which obstructs cleaning and storage.
Innovation Solution
A support mechanism is integrated into the nozzle of the vacuum cleaner, allowing it to pivot or slide between projected and retracted states, reducing the overall size and bulkiness by positioning the support closer to the floor, with optional wheels for easy movement and actuation via user-operated mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support is mounted to the main body of the vacuum cleaner, then the vacuum cleaner can stand in an upright position, but the support becomes longer and the vacuum cleaner becomes bulkier
Solution Approach 1:
The support is relocated from the main body (upper dimension) to the nozzle (lower dimension closer to the floor). This dimensional shift allows the support to be shorter while still providing adequate support area, as it can extend more directly to the underlying surface without the intermediate distance from the main body.
Solution Approach 2:
The support functionality is localized to the nozzle area rather than being integrated into the main body. This local placement optimizes the support geometry for the specific location, allowing it to reach the floor more efficiently and reduce overall length while maintaining stability.
2Stability of the object's composition
If the support is made longer to reach the floor from the main body, then the vacuum cleaner can stand stably, but the support obstructs cleaning operations and storage
Solution Approach 1:
By positioning the support at the nozzle level (lower dimension) rather than the main body (upper dimension), the support operates in a spatial zone that does not interfere with the user's handling of the main body and handle during cleaning operations.
Solution Approach 2:
The support function is separated from the main body structure and integrated into the nozzle assembly. This segmentation allows the support to be independently positioned and sized without compromising the main body's maneuverability or the user's access to cleaning areas.
3Stability of the object's composition
If the support is positioned rearward of the nozzle, then the nozzle can be supported horizontally, but the vacuum cleaner requires more space for storage
Solution Approach 1:
The support is integrated into the nozzle assembly itself, utilizing the local structure to provide both nozzle support and vacuum cleaner stability. This localized integration eliminates the need for additional rearward extension structures that would increase storage space requirements.

AI summary
According to the present invention, there is provided an upright vacuum cleaner comprising a nozzle (200) and a support (250) movable between a projected state and a retracted state, wherein the support in its projected state is adapted to support the vacuum cleaner in a self standing position. The support is mounted to the nozzle and projects from the nozzle in its projected state. The present invention is advantageous in that the vacuum cleaner is less bulky as compared to prior art techniques.
