Vacuum Agitator Cleaning with Position-Triggered Power Boost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating agitators in cleaning devices, such as vacuum cleaners, accumulate debris like hair and fibers, which reduces their performance, is difficult to remove manually, and can cause imbalance, friction, and damage to bearings.
Innovation Solution
An agitator cleaning system with a movable cleaner that engages the agitator during rotation, driven by an electric motor with adjustable power levels, and a detection system to indicate when the cleaner is in operation, ensuring efficient debris removal and preventing motor overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of debris is used, then the device structure remains simple, but the ease of operation deteriorates and time consumption increases
Solution Approach 1:
The system enables self-service cleaning by automatically detecting when the agitator cleaner is in the second position and autonomously adjusting motor power without requiring user intervention or manual monitoring
Solution Approach 2:
The system performs preliminary action by proactively increasing motor power before debris accumulation can significantly impact agitator performance, based on detection of the cleaner's position rather than waiting for performance degradation
2Reliability
If motor power is continuously high to prevent debris accumulation, then agitator performance is maintained, but energy consumption increases
Solution Approach 1:
The system implements periodic action by intermittently applying high motor power only during specific cleaning cycles when the agitator cleaner is engaged, rather than maintaining continuous high power operation
Solution Approach 2:
The system changes motor power parameters dynamically based on the cleaning state, switching between first power level (lower) and second power level (higher) according to detector signals
3Reliability
If the agitator cleaner is always engaged to remove debris, then agitator cleanliness is improved, but friction and motor load increase
Solution Approach 1:
The system applies dynamics by making the motor power level variable rather than fixed, adjusting power output based on the real-time position of the agitator cleaner to optimize the balance between cleaning effectiveness and motor load

AI summary
A vacuum cleaner agitator system having an agitator, an electric motor to rotate the agitator, a power source, and an agitator cleaner. The cleaner moves between a first position in which it is spaced from the agitator and a second position in which it engages the agitator to remove debris while the agitator rotates. The system also has a detector configured to indicate when the cleaner is in the second position. A drive control system connects the electric motor, electric power source, and agitator cleaning detector. The drive control system has a first drive mode to drive the electric motor at a first power level, and a second drive mode, activated upon receiving an indication from the detector that the cleaner is in the second position, to drive the electric motor at a second power level that is greater than the first power level.
