Vibrating Suction Nozzle for Carpet Dust and Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction nozzles for vacuum cleaners and robot cleaners face inefficiencies in cleaning surfaces, including reduced cleaning performance due to vibration tools that deteriorate performance on carpets and generate noise on hard floors, clogging issues with rotary brushes, and inability to reach cornered surfaces, leading to reduced cleaning efficiency and increased power consumption.
Innovation Solution
A suction nozzle with a vibration cleaning unit that includes a vibration source, transfer frame, and vibration bar, designed to resonate and efficiently clean surfaces by vibrating along the nozzle's direction, featuring a pollutant inflow space and elastic members for low power operation and extended cleaning reach, including cornered areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vibration tool is used to clean carpets, then pollutants are guided to rise up to the surface, but the vibration tool presses the dust stuck in the carpet and deteriorates cleaning performance
Solution Approach 1:
The patent employs a vibration motor that generates vibrations transmitted through a vibration transmission unit to a cleaning member, utilizing mechanical vibration to dislodge pollutants from carpet surfaces without excessive pressing force, thereby resolving the contradiction between lifting pollutants and pressing dust into the carpet
2Productivity
If a vibration tool strikes the floor to clean, then pollutants are dislodged, but noise is generated due to striking sound
Solution Approach 1:
Instead of using a striking mechanism that generates noise, the patent uses a vibration motor to generate controlled vibrations that are transmitted to the cleaning member, achieving pollutant dislodgement through vibration rather than impact, thereby reducing noise while maintaining cleaning efficiency
3Productivity
If a rotary brush is used to clean surfaces, then pollutants are brushed away, but hair gets tangled on the brush and structures around the suction port causing clogging
Solution Approach 1:
The patent replaces the rotary brush with a vibration-based cleaning member that oscillates or vibrates to dislodge and move pollutants including hair, preventing hair from wrapping around rotating components and reducing clogging of the suction port while maintaining effective surface cleaning
4Productivity
If a rotary brush is driven at several thousands of rpm, then cleaning performance is improved, but large power consumption occurs
Solution Approach 1:
The patent uses a vibration motor to drive the cleaning member at vibration frequencies that are effective for cleaning but consume less power than high-speed rotary motors, achieving a balance between cleaning performance and energy efficiency through vibrational motion rather than high-speed rotation
5Productivity
If the suction port is formed with an area smaller than the housing area to form a vacuum, then dust suction efficiency is improved, but the suction port cannot reach cornered surfaces
Solution Approach 1:
The patent employs an elastic member that allows the cleaning member to deform or adjust its position dynamically, enabling the suction nozzle to adapt to cornered surfaces and irregular geometries while maintaining the vacuum effect, thereby extending reach to previously inaccessible areas without sacrificing suction efficiency
