Solution Overview

Problem

Existing all-in-the-head vacuum cleaners have a higher profile due to the accommodation of suction motor and cyclone components, making them unsuitable for low-clearance cleaning applications such as under couches.

Innovation Solution

The suction motor is relocated to an upper portion, pivotably coupled to the surface cleaning head, with dual smaller diameter cyclones housed within the head, allowing for a lower profile design while maintaining performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If suction motor and cyclone components are accommodated within the surface cleaning head, then the vacuum cleaner can be compact and integrated, but the profile height becomes higher than desired for low-clearance applications

Engineering Contradiction:
Improvecomponent integrationVSAvoidprofile height
Core Design Contradiction:
Device complexityVSLength of stationary object

Solution Approach 1:

The vacuum cleaner is divided into two main segments: the surface cleaning head and the upper portion containing the suction motor. The cyclone assembly is further segmented into a removable dust cup and a fixed cyclone housing. This segmentation allows the heavy motor to be separated from the cleaning head, reducing the head's profile height while maintaining component integration through fluid coupling between segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The suction motor is relocated from the horizontal plane of the cleaning head to the vertical dimension in the upper portion. This dimensional relocation allows the motor to be positioned above the cleaning head rather than within it, significantly reducing the profile height of the cleaning head while keeping the motor accessible and functional through the fluid coupling system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Length of stationary object

If the suction motor is relocated to an upper portion, then the surface cleaning head profile is reduced for low-clearance cleaning, but the device requires pivotable coupling and fluid connections between sections

Engineering Contradiction:
Improvecleaning head heightVSAvoidpivotable coupling mechanism
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

A fluid coupling mechanism acts as an intermediary between the suction motor in the upper portion and the cyclone assembly in the cleaning head. This intermediary allows rotational motion and suction force to be transmitted through the pivotable connection without requiring direct mechanical coupling, simplifying the pivot mechanism while maintaining functional integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection between the upper portion and cleaning head is made dynamic through a pivotable coupling that allows relative motion. This dynamic connection enables the cleaning head to be positioned at different angles for various cleaning applications while maintaining the suction connection through the flexible fluid coupling, adapting the system to different operational requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

A surface cleaning apparatus provides a lower profile surface cleaning head by moving at least the suction motor out of the surface cleaning head. The suction motor may be located in an upper portion (e.g., in a wand) pivotably coupled to the surface cleaning head and fluidly connected to a cyclone assembly located in the surface cleaning head. The cyclone assembly may include first and second opposing cyclones with smaller diameters (e.g., as compared to a single cyclone used in existing “all in the head” vacuums) to provide a lower profile with substantially the same or better performance.
