Solution Overview
Problem
Existing filtration and vacuum devices are ineffective in both air and water environments due to differences in media properties, leading to motor damage or inefficiency, and require separate devices for each environment, increasing time and cost for cleaning tasks involving both.
Innovation Solution
A fluid vacuum pump with a motor assembly and impeller system configured for multiple mediums, using adjustable power transmission, clutch mechanisms, and variable impeller configurations to adapt to different fluids, allowing simultaneous operation in air and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vacuum device is designed with high-speed impeller and high-RPM motor for air operation, then air vacuum performance is improved, but water operation causes motor damage and ineffective operation due to excessive torque and current draw
Solution Approach 1:
The patent employs a dynamic clutch mechanism that automatically engages or disengages the impeller from the motor shaft based on detected fluid conditions. When water is detected, the clutch disengages the high-RPM motor from the impeller, preventing motor damage while maintaining the ability to operate in air at high speeds when needed.
Solution Approach 2:
The system changes operational parameters by switching between different motor-impeller configurations based on the medium detected. The motor operates at high RPM for air but transitions to low RPM when water is detected, adapting performance parameters to match environmental conditions and prevent damage.
2Reliability
If separate devices are used for air vacuuming and water filtration, then each device can be optimized for its specific environment, but time and cost increase due to requiring multiple devices and switching between them
Solution Approach 1:
The patent creates a universal cleaning device that incorporates both air vacuuming and water filtration capabilities in a single unit. The device uses sensors to detect the operating environment and automatically switches between air-optimized and water-optimized configurations, eliminating the need for users to physically switch between separate devices and reducing both time loss and equipment investment.
Solution Approach 2:
The system merges previously separate air vacuum and water filtration functions into a single integrated device. By combining multiple impeller-motor systems and control mechanisms into one unit, the patent allows users to have one device that can handle both air and water environments, consolidating equipment needs and eliminating switching time.
3Ease of operation
If battery-powered devices are used in cross-environment operation with inappropriate motor-impeller matching, then device portability is maintained, but rapid battery discharging or damage occurs
Solution Approach 1:
The patent changes energy consumption parameters by dynamically adjusting motor RPM and torque output based on detected fluid conditions. When water is detected, the system switches to a configuration that consumes appropriate power levels for water pumping, preventing excessive battery discharge that would occur if the air-optimized high-RPM motor ran in water.

AI summary
A fluid vacuum pump includes a motor assembly including a single motor or multiple motors, where one motor may be configured for operation in a first medium and another motor may be configured for operation in a second medium; an impeller assembly including a single impeller, which may of a fixed or variable configuration, or multiple impellers, where one impeller may be configured for operation in a first medium and another impeller may be configured for operation in a second medium; and a linkage operatively connecting and adjustably transmitting power from the motor assembly to the impeller depending on the type of medium present.
