Liquid Aspirator Separation and Backflow Control in Tilted Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid vacuuming devices face inefficiencies in separating liquids from air, leading to excessive energy consumption and potential water backflow into exhaust channels, particularly when tilted or used in orientations other than upright.
Innovation Solution
The design incorporates a motor-driven rotor within the hollow chamber that acts as a separating device, deflecting the liquid/air mixture based on inertia differences, and a flow labyrinth to prevent water entry into the exhaust air channel, along with an on/off function controlled by pressure and orientation switches to optimize suction performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a motor-driven vacuum subassembly operates continuously to maintain suction performance, then the suction capability is improved, but the energy consumption increases and restart time becomes excessively long when the device is tilted or oriented unfavorably
Solution Approach 1:
The patent applies dynamics by making the motor-driven vacuum subassembly controllable rather than continuously operating. The control unit enables the motor to be switched on/off or adjusted based on real-time detection of device orientation and liquid presence, allowing the system to adapt its power consumption to actual operational needs while maintaining suction performance when required
2Adaptability or versatility
If the device operates in tilted or unfavorable orientations, then the versatility of use is improved, but liquid backflow into the exhaust air channel occurs
Solution Approach 1:
The patent introduces a control unit as an intermediary between the sensor detection system and the motor-driven vacuum subassembly. This control unit processes orientation data and liquid presence signals, then intelligently controls the motor operation to prevent liquid backflow while maintaining device versatility across different orientations
3Use of energy by moving object
If the motor is turned off or reduced power to save energy, then the energy consumption is reduced, but the restart time becomes excessively long when needed
Solution Approach 1:
The patent implements feedback control through sensors that continuously detect device orientation and liquid presence, providing real-time information to the control unit. This feedback mechanism allows the system to immediately react to changing conditions, turning the motor on or adjusting power levels based on actual operational requirements rather than following a fixed timing pattern, thus eliminating excessive restart delays
