Vacuum cleaner head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner heads are ineffective in accessing and cleaning confined or low-clearance areas due to structural limitations, such as size and design flaws, which prevent them from maintaining suction capability when maneuvering under furniture and appliances, requiring operators to bend or kneel for effective cleaning.
Innovation Solution
A flat, elongated vacuum cleaner head with a flexible hose fitting set back from the back end, allowing it to be angled and bent downward for stable engagement with the floor, maintaining suction while enabling the operator to maintain an upright posture, and a suction head with wing-like members for enhanced coverage and suction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the vacuum cleaner head is made long and flat to access low-clearance areas, then the ability to reach confined areas is improved, but the head lifts off the floor surface due to pivot point action at the attachment junction
Solution Approach 1:
The invention extracts the attachment junction from the back end of the vacuum cleaner head and relocates it to the front end, removing the source of the pivot point problem that causes the head to lift off the floor surface during operation
2Device complexity
If the attachment junction is at the back end of the vacuum cleaner head, then the structure is simplified, but the head separates from the floor surface when maneuvering into confined areas
Solution Approach 1:
The invention inverts the conventional attachment arrangement by placing the attachment junction at the front end of the vacuum cleaner head instead of the back end, which prevents the head from lifting off the floor surface while maintaining structural simplicity
3Manufacturing precision
If the operator bends or kneels down to direct the vacuum head into confined areas, then the head can be positioned accurately, but the operator's comfort and posture are compromised
Solution Approach 1:
The vacuum cleaner head design with front-end attachment enables the head to self-maintain floor contact through its structural configuration, eliminating the need for the operator to bend or kneel and allowing operation from a comfortable upright position

AI summary
A vacuum cleaner head with a suction component consisting of laterally-opposed wing-like members positioned transversely to the front end of the head used to access and suction dirt, debris and fluids within confined or low-clearance areas under furniture and appliances and includes a generally thin flat elongated hollow member designed to reach maximum extension and floor surface coverage within the confined or low-clearance areas. Included is a flexible hollow hose fitting set back and disposed at an acute angle from the back end of the vacuum cleaner head for slidably mounting the vacuum cleaner head to a hollow hose wand. The hollow hose wand with a bottom end releasably attached to the flexible hollow hose fitting is adapted to be bent downward toward the floor surface when a sufficient downward pressure is exerted by the user upon the hollow hose wand used for maneuvering (approximately eleven inches in width) the vacuum cleaner head. This action also ensures that the head continues in constant sliding engagement with the floor to prevent the head from separating or lifting off from the floor surface and neutralizing the otherwise full functional capability of the suction head.
