Vacuum cleaner and controlling method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners struggle to effectively control suction power and brush operation based on the material of the floor and the amount of dust, leading to increased operation resistance and potential brush locking on carpets.
Innovation Solution
A vacuum cleaner system that uses dust and floor sensors to adjust suction power and brush rotation speed and height dynamically, ensuring optimal cleaning performance across different floor materials without increasing operation resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction power is increased to improve dust pickup performance, then dust suction capability is improved, but operation resistance increases and brush may lock on carpets
Solution Approach 1:
The suction power is made dynamically adjustable based on detected floor material type. The system transitions from fixed suction power to variable suction power that adapts to different surfaces (hard floor vs. carpet), allowing high power on hard floors for maximum dust pickup while reducing power on carpets to prevent brush locking and excessive resistance
Solution Approach 2:
The system changes the suction power parameter according to the detected floor material. By detecting whether the surface is a hard floor or carpet, the controller adjusts the suction motor power output accordingly, optimizing the balance between dust pickup effectiveness and operation resistance prevention
2Productivity
If brush rotation speed is increased to improve dust separation, then dust separation effectiveness is improved, but brush locking on carpets increases
Solution Approach 1:
The brush rotation speed is made dynamically controllable based on floor material detection. The system adjusts brush speed in real-time according to whether it is cleaning a hard floor or carpet, maintaining effective dust separation on hard floors while preventing brush locking on carpets through reduced speed
Solution Approach 2:
The brush motor speed parameter is changed according to the detected surface type. The controller receives floor material information and adjusts the brush rotation speed parameter accordingly, optimizing dust separation effectiveness while minimizing the risk of brush locking on high-pile surfaces
3Productivity
If brush height is decreased to improve dust pickup from floor, then dust pickup effectiveness is improved, but brush locking on carpets increases
Solution Approach 1:
The brush height is made dynamically adjustable based on detected floor material. The system transitions from fixed brush height to variable height that adapts to different surfaces, allowing low brush position on hard floors for effective dust pickup while raising the brush on carpets to prevent locking
Solution Approach 2:
The brush height parameter is changed according to the detected floor material type. The controller adjusts the brush position parameter based on whether the surface is hard floor or carpet, optimizing dust pickup effectiveness while preventing brush locking on carpets
