Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid transfer devices struggle with clogging due to contaminants like dirt, solid particles, and debris, which can damage the pump or jam the impeller, especially in applications such as flooded areas like basements, construction sites, and landfills, where effective filtration and sediment control are needed.
Innovation Solution
A liquid filtering and transfer device with a substantially rigid housing and a permeable filtering surface that channels debris away from the pump, using spiral grooves and adjustable openings to prevent clogging, and an electrically driven pump with a floatation device to prevent dry running, allowing for efficient filtration and transfer of fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pump is placed in a filtering assembly to prevent contaminants from entering, then pump reliability is improved, but device complexity increases
Solution Approach 1:
A filtering assembly is introduced as an intermediary component between the contaminated fluid and the pump. The assembly includes a housing with a filtering surface that allows fluid passage while blocking solid particles and debris, preventing contaminants from reaching and damaging the pump impeller
Solution Approach 2:
The device is segmented into distinct functional zones: an outer housing containing the filtering surface, an inner cavity housing the pump, and a discharge system. This segmentation allows the filter to be serviced independently and enables the pump to operate in a protected environment
2Reliability
If a filtering surface is used to remove solid particles, then pump protection is improved, but fluid flow resistance increases
Solution Approach 1:
The filtering assembly incorporates a floatation device that dynamically adjusts the filter position based on fluid level. The float rises and falls with the fluid, maintaining optimal filtering coverage while allowing unobstructed flow paths to remain open, reducing energy loss from excessive filtration resistance
3Duration of action of moving object
If the pump is protected from contaminants, then operational duration is improved, but ease of operation decreases
Solution Approach 1:
The floatation device automatically controls the filtering assembly's position and operation based on fluid levels, eliminating the need for manual intervention. The system self-regulates to maintain optimal filtering and pump protection throughout extended operational periods

AI summary
A liquid transfer device having a housing with a top end, a bottom end, a sidewall, and an inner cavity. The sidewall has an inner surface and an outer surface. There is a plurality of openings traversing said sidewall. Also present is a filtering surface that covers the openings. The water or other liquids are pumped or transferred with a pump contained inside the inner cavity, with a fluid exit used for carrying the water out towards exterior hosing.
