Vaccum cleaner and nozzle for cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners have a limited cleanable area due to a fixed suction nozzle with a brush, and they struggle to effectively remove hairs and pet hairs from the brush, which complicates maintenance.
Innovation Solution
A nozzle design with movable members that allow the suction area to be varied, incorporating a brush cleaning unit with a variable width that can move along with the brushes to separate foreign substances, including hairs, by using a lever and transmission mechanism to increase cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suction nozzle has a fixed brush area, then the structure is simple, but the cleanable area is limited
Solution Approach 1:
The suction nozzle incorporates movable members that can slide relative to the nozzle body, transforming the fixed brush area into a dynamic, adjustable configuration. This allows the cleanable area to be varied by moving the movable members along the nozzle, enabling adaptation to different cleaning requirements while maintaining a relatively simple overall structure.
2Ease of operation
If an air jet is used to clean the brush, then small particles are separated, but hairs and pet hairs cannot be easily removed
Solution Approach 1:
The invention introduces a dedicated brush cleaning unit as an intermediary mechanism between the brush and the user. This unit includes cleaning members that physically contact and remove hairs and pet hairs from the brush, providing a more effective solution than air jets alone while maintaining ease of operation through automated or assisted cleaning action.
3Adaptability or versatility
If the brush cleaning unit is stationary, then the structure is simple, but it cannot adapt to variable suction nozzle width
Solution Approach 1:
The brush cleaning unit is designed with movable components that can adjust their position and width to match the variable configuration of the suction nozzle. As the movable members of the suction nozzle move, the brush cleaning unit accordingly adjusts to maintain proper alignment and cleaning effectiveness, enabling adaptation without excessive structural complexity.
