Floating Weir Basket for Pool Skimmers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool skimmers are ineffective in cleaning the entire pool surface, unstable, and prone to tipping over, and they allow air into the pump system when the water level drops, leading to motor failure and structural issues with above-ground pools.
Innovation Solution
A multi-functional floating pool skimmer that attaches to existing skimmers or vacuum lines, uses a T-fitting for simultaneous suction, includes a floating weir to prevent debris escape, and incorporates ballast for stability, allowing it to rise and fall with water levels to prevent air entry into the pump system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile floating skimmer is used, then the skimmer can move freely on the pool surface, but it becomes unstable and tips over when not operating
Solution Approach 1:
The patent applies ballast weights positioned in the lower portion of the skimmer housing to counterbalance the floating structure. This creates a stable upright position by lowering the center of gravity, preventing the skimmer from tipping over when not in operation while maintaining its ability to move freely on the water surface
2Stability of the object's composition
If a fixed skimmer is used, then the skimmer structure is stable, but it allows air into the pump system when water level drops
Solution Approach 1:
The patent employs a floating skimmer design that dynamically adjusts its vertical position with changing water levels. The skimmer rises and falls on the water surface, maintaining its inlet opening at the appropriate depth regardless of water level fluctuations, thereby preventing air from entering the pump system while preserving structural stability through ballast
3Device complexity
If a single fixed skimmer is used with an automatic vacuum device, then the system is simple, but the skimmer cannot clean the pool surface effectively
Solution Approach 1:
The patent designs the floating skimmer to perform multiple functions: it serves as both a surface skimmer that cleans debris from the pool surface and as a suction inlet for the automatic vacuum device. The T-connector allows the vacuum device to draw suction from the same floating skimmer, eliminating the need for separate fixed skimmers and vacuum inlets while maintaining both surface cleaning and system simplicity
4Ease of operation
If fixed skimmers are attached to above ground pool walls, then the skimmers are positioned correctly, but the pool walls fail under the weight
Solution Approach 1:
The patent removes the fixed mounting structure from the pool wall entirely, replacing it with a floating skimmer that operates independently on the water surface. This extracts the skimmer function from the pool wall structure, eliminating the additional weight load while maintaining proper skimmer positioning through buoyancy and ballast mechanisms
