Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool skimmers face issues with excessive suction, which can lead to dangerous conditions and manufacturing challenges, particularly with venturi skimmers that have external tubing and complex designs, making them difficult to clean and prone to damage.
Innovation Solution
A pool skimmer design featuring a venturi system with a pump inlet port and nozzles that direct spray towards a pool return port, combined with an angled pool throat extension and a channel system that allows air to enter, preventing over-suction and simplifying maintenance by eliminating external tubing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a venturi skimmer with external tubing is used to enhance skimming action, then flow through the skimmer is increased, but the device becomes difficult to clean and prone to damage
Solution Approach 1:
The invention removes the external tubing from the venturi system and integrates the nozzle directly into the skimmer basket assembly. This extraction of the problematic external component eliminates the cleaning difficulty while preserving the flow enhancement benefits of the venturi effect.
Solution Approach 2:
The nozzle is merged with the skimmer basket assembly, creating an integrated unit that eliminates separate external tubing. This consolidation improves accessibility for cleaning and maintenance while maintaining the venturi-induced flow enhancement.
2Reliability
If a central perforated pylon is added to the skimmer basket to provide air relief, then air relief is achieved, but the basket capacity is reduced and manufacturing becomes difficult
Solution Approach 1:
The invention replaces the complex central perforated pylon structure with a simpler air relief mechanism integrated into the basket design. This extraction of the cumbersome pylon structure maintains air relief functionality while simplifying manufacturing and preserving basket capacity.
Solution Approach 2:
Instead of adding a complex internal pylon structure to provide air relief, the invention uses a simpler approach where air relief is achieved through the basket design itself, inverting the traditional approach and reducing manufacturing complexity.
3Reliability
If an external tube is run from the upper interior of the skimmer body to below the basket, then air relief is provided, but the tube becomes small, costly to manufacture, and difficult to clean
Solution Approach 1:
The invention eliminates the external tube configuration entirely by integrating air relief functionality directly into the basket assembly. This extraction of the complex tubed system reduces device complexity and improves cleanability while maintaining air relief reliability.
Solution Approach 2:
Air relief and the basket structure are merged into a single integrated component, eliminating the need for separate external tubing. This consolidation reduces device complexity and manufacturing costs while preserving the air relief function.

The solution effectively prevents dangerous over-suction conditions and enhances maintenance accessibility while maintaining efficient debris entrapment and flow, reducing manufacturing costs and complexity.
Implementation Method 1
venturi skimmers equipped with a pressure jet located to entrain water within the skimmer and eject it back to the pool
Implementation Method 2
a skimming device connected to the suction of a pump to draw water from the pool at or very near the pool surface

AI summary
A pool skimmer including a skimmer housing and a venturi system is disclosed. The skimmer housing includes a pool throat opening, an angled pool throat extension. A pump inlet port into the skimmer housing includes an upper end and bayonet lugs, and an internally threaded surface between the bayonet lugs and the upper end of the pump inlet port. A nozzle comprises a nozzle housing with bayonets on an external surface of the nozzle housing, the bayonets releasably engaged with the bayonet lugs of the pump inlet port, wherein when the bayonets of the nozzle housing are in a fully tightened position in relation to the bayonet lugs of the pump inlet port, the at least a first nozzle is directed to spray toward the pool return port of the skimmer housing.
