Upright Vacuum Cleaner Frame Layout for Visible Dust Container Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern handheld upright or stick vacuum cleaners face difficulties in determining when the dust container needs emptying and in removing it for cleaning, as the dust container is often hard to access and identify when full.
Innovation Solution
The vacuum cleaner design features a housing with a cavity formed between a bottom portion and a frame portion, including at least two support bars along the longitudinal direction of the vacuum cleaner, which enhances rigidity and allows a large portion of the dust container to be exposed, facilitating inspection and access without removing the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the cavity size is increased to accommodate a larger dust container, then the dust collection capacity is improved, but the rigidity of the vacuum cleaner housing deteriorates
Solution Approach 1:
The frame portion is segmented into multiple support bars (first support bar, second support bar, third support bar) that divide the cavity space. These segmented structural elements provide distributed support to maintain housing rigidity while accommodating a larger cavity volume for the dust container.
Solution Approach 2:
The support bars are strategically positioned at specific locations within the frame portion where structural reinforcement is most needed. The first support bar is positioned to support the front of the dust container, the second support bar supports the rear, and the third support bar provides additional reinforcement, creating localized strength zones that maintain overall housing rigidity despite the large cavity volume.
2Loss of information
If the dust container is made fully transparent for easy inspection, then the visibility of contents is improved, but the structural strength of the container deteriorates
Solution Approach 1:
The dust container employs a mixed-material construction where different portions have different transparency properties. The front wall and rear wall are made transparent to allow visibility of dust contents, while the side walls may be made of stronger opaque material. This local differentiation of material properties enables both inspection capability and structural strength in critical areas.
3Strength
If the support bars are made thicker to increase rigidity, then the housing strength is improved, but the visibility of the dust container walls deteriorates
Solution Approach 1:
The support bars are positioned at specific locations where structural reinforcement is most critical (front, rear, and intermediate positions), rather than being distributed uniformly throughout the frame. This localized placement of thicker support bars provides necessary rigidity while minimizing obstruction to the visible area of the dust container walls.
Solution Approach 2:
The support bars are arranged in a three-dimensional configuration around the dust container, with bars positioned at different longitudinal and lateral locations. This spatial arrangement provides structural support from multiple dimensions while allowing the dust container walls to remain visible from the front and rear viewing angles.

AI summary
The present invention relates to an upright vacuum cleaner having a main longitudinal extension, comprising a housing provided with a cavity, which cavity is formed between a bottom portion, and a frame portion, and a dust container comprising a wall and having two lateral sides, wherein the dust container is arranged in the cavity, and wherein the frame portion comprises at least two support bars arranged substantially in the longitudinal direction of the vacuum cleaner, one along each lateral side of the dust container, such that the at least two support bars contribute to the rigidity of the vacuum cleaner while a major portion of the wall of the dust container remains visible.
