Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool cleaning systems with booster pumps experience noise issues and increased motor strain due to throttling of water flow from larger diameter tubing to smaller diameter fittings, leading to inefficient operation.
Innovation Solution
A booster pump assembly with a front and rear housing, a motor-driven impeller system, and matching 1½ inch diameter inlet and outlet conduits to maintain consistent water flow diameter, reducing noise and strain on the motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If booster pump fittings are made smaller (3/4 inch) to reduce device complexity, then ease of manufacture is improved, but noise increases and motor strain increases due to throttling
Solution Approach 1:
The patent changes the diameter parameter of the booster pump fittings from the conventional 3/4 inch to 1 1/2 inches, matching the pool cleaner fittings. This parameter change eliminates the throttling effect that causes noise and motor strain, while still allowing for economical manufacturing using standard pool industry fitting sizes.
2Ease of manufacture
If booster pump fittings are made smaller (3/4 inch) to reduce device complexity, then ease of manufacture is improved, but motor strain increases due to throttling
Solution Approach 1:
The patent changes the diameter parameter of the booster pump fittings from the conventional 3/4 inch to 1 1/2 inches, matching the pool cleaner fittings. This parameter change eliminates the throttling effect that causes excessive motor strain, allowing the motor to operate more efficiently without the added load of forcing water through restricted openings.
3Productivity
If larger diameter fittings (1 1/2 inch) are used to reduce noise and motor strain, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The patent makes the booster pump fittings universal by using the standard 1 1/2 inch size that matches pool cleaner fittings, eliminating the need for separate reduction fittings. This universal sizing approach actually reduces device complexity by simplifying the connection system while improving operational efficiency.
4Productivity
If throttling is applied to match flow to booster pump capacity, then flow rate is controlled, but noise increases and energy is lost
Solution Approach 1:
The patent changes the fitting diameter parameter to eliminate the need for throttling. By using 1 1/2 inch fittings that match both the pool cleaner and provide adequate flow capacity, the system achieves proper flow rate control without the energy losses associated with throttling through restricted openings.

AI summary
Assemblies and methods for a booster pump used in a pool cleaning/filtration system are provided. An exemplary booster pump assembly is adapted to increase the water pressure of water flow for use in a pool cleaning system. The booster pump includes a front housing defining a substantially circular geometry having an inlet positioned substantially in the center of the front housing and extending axially outward with respect to the front housing. The booster pump also includes an outlet extending substantially laterally with respect to the front housing. The front housing and the rear housing form an enclosure for positioning of an impeller. The inlet and the outlet are each coupled to conduits having substantially similar flow diameters, and the water passing through the outlet at an increased water pressure is sufficient to make operable a positive pressure pool cleaner. Advantageous support structures and drain plug configurations are also provided.
