Vacuum Cleaner Handle Control for Temporary Suction Boost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners lack a simple method to temporarily increase suction power in response to specific cleaning situations, which limits user flexibility during cleaning.
Innovation Solution
A vacuum cleaner with a handle-mounted pushbutton switch or slide control and a radio module that allows for brief increases in blower power, with automatic reduction to preset levels, and includes a pressure sensor to prevent excessive negative pressure and pushing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pushbutton switch or slide control is mounted on the handle for controlling suction power, then the user can easily adjust suction power levels, but the user cannot temporarily increase suction power in response to specific cleaning situations
Solution Approach 1:
The system dynamically adjusts suction power based on user input signals. The control device receives signals from the pushbutton switch or slide control on the handle and automatically adjusts the blower motor power accordingly, enabling temporary power boosts when needed while maintaining ease of operation through automatic control.
Solution Approach 2:
The system uses signal feedback from the handle control to the vacuum cleaner housing control device. The pushbutton switch or slide control sends signals via radio communication to the control device, which then adjusts the blower power based on these feedback signals, allowing the user to temporarily increase power for specific cleaning situations.
2Power
If the blower power is increased to clean stubborn dirt effectively, then the suction power increases, but the negative pressure increases causing high pushing forces on the floor nozzle
Solution Approach 1:
The control device monitors negative pressure in the dust collection chamber and uses this feedback to regulate blower power. When negative pressure becomes too high (causing excessive pushing forces), the control device automatically reduces power to prevent the floor nozzle from getting stuck, while still allowing temporary power increases for effective cleaning of stubborn dirt.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables immediate and effective cleaning by allowing simple, temporary power boosts while preventing unfavorable operating points and ensuring user comfort by avoiding excessive pushing forces.
Implementation Method 1
the pushbutton switch or slide control is in radio communication with the control device (8) in the vacuum cleaner (1) via the radio module (7)
Implementation Method 2
If the dust bag is still empty and there is therefore a high negative pressure in the dust collection chamber

AI summary
The invention relates to a vacuum cleaner (1) with a handle (3) for steering a suction attachment (5) mounted on the base of the suction tube (4), and with a control unit (8) arranged in the vacuum cleaner (1), which includes an automatic suction power regulation (10) with switching and control means and is designed to adjust the power of the blower motor. According to the invention, a push-button switch (6) or slider and a radio module (7) are arranged in or on the handle (3), and the push-button switch (6) or slider communicates wirelessly with the control unit (8) in the vacuum cleaner (1) via the radio module (7), whereby a temporary increase in blower power relative to the preset power can be activated by pressing the push-button switch (6) or slider.
