Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face inefficiencies in energy consumption and suction power due to clogged filters, leading to over-regulation and waste of energy, especially in low-power devices where suction power is insufficient after a short period of use.
Innovation Solution
A device and method for controlling automatic filter cleaning in vacuum cleaners, which determines suction air flow and adjusts motor/fan unit power to activate cleaning when the suction air flow falls below a limit value, ensuring constant suction power and improving energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the motor/fan unit power is increased to maintain suction power after filter clogging, then suction power is maintained, but energy consumption increases
Solution Approach 1:
The system performs preliminary detection of filter clogging conditions by monitoring suction air flow and motor power values. When threshold values are exceeded, the system proactively triggers filter cleaning before significant performance degradation occurs, preventing the need for continuous high-power operation and reducing overall energy consumption.
Solution Approach 2:
The system continuously monitors suction air flow and motor power consumption, comparing actual values against threshold values. This feedback mechanism enables the system to detect filter clogging conditions and automatically trigger cleaning operations, optimizing the balance between maintaining suction power and minimizing energy consumption.
2Power
If manual readjustment of suction power is performed to compensate for filter clogging, then suction power is restored, but user convenience decreases and energy waste increases
Solution Approach 1:
The system automatically detects filter clogging conditions by monitoring suction air flow and motor power, and autonomously triggers filter cleaning operations without requiring user intervention. This self-service approach maintains optimal suction power while eliminating the need for manual readjustment, thereby improving user convenience and preventing energy waste from over-regulation.
Solution Approach 2:
The continuous monitoring and automatic response system provides real-time feedback on filter condition and autonomously adjusts operation by triggering cleaning when needed, eliminating the need for manual user intervention and maintaining optimal performance automatically.
3Power
If a high-power motor/fan unit is used to compensate for filter clogging, then suction power is maintained, but device complexity and cost increase
Solution Approach 1:
The system detects filter clogging early through monitoring suction air flow and motor power values against thresholds, and triggers cleaning before significant performance loss occurs. This allows the use of lower-power motor/fan units that only need to handle normal operating conditions, reducing device complexity and cost while maintaining suction power through timely filter maintenance.
4Power
If the filter is cleaned frequently to maintain suction power, then suction power is maintained, but energy consumption increases
Solution Approach 1:
The system uses feedback from suction air flow and motor power monitoring to determine precisely when filter cleaning is needed, triggering cleaning only when threshold values are exceeded. This on-demand approach maintains suction power while avoiding unnecessary cleaning operations that would waste energy, optimizing the balance between performance and energy consumption.
