Adjustable Pool Skimmer for Varying Water Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skimming devices are not suitable for shallow pools as they cannot adapt to varying water levels, making them ineffective for pools with low or high water heights, particularly in shallow swimming pools for young children.
Innovation Solution
A skimming device with an adjustable height mechanism that allows the water inlet cap to be positioned relative to the water discharge orifice, enabling use in both low and high water levels by sliding the upper body along a guide and using locking elements to secure different height positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional skimming device with fixed height is used, then the device structure is simple, but the device cannot adapt to different water levels in shallow pools
Solution Approach 1:
The skimming device incorporates an adjustable height mechanism that allows the water inlet cap to be positioned at different heights relative to the water discharge orifice. The upper body can slide along a guide and be locked at various positions, enabling the device to adapt to different water levels in shallow pools while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the water inlet cap is positioned far from the water discharge orifice, then the device can handle higher water levels, but the device vertical size increases
Solution Approach 1:
The upper body of the skimming device is designed to slide within and along the guide structure, allowing compact storage when not in use while providing extended adjustment range when needed. This nesting-like configuration enables a wide range of water level adaptation without significantly increasing the device's permanent vertical footprint.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the skimming device to effectively adapt to different water levels in shallow pools, ensuring efficient filtration and water circulation regardless of the water height, from low levels for young children to higher levels for older children.
Implementation Method 1
a perforated floating cap (2) for the entry of water
Implementation Method 2
a pump (9) to push the water towards the outside of the support (4) through a filter (10)
Implementation Method 3
a pump (9) to push the water towards the outside of the support (4) through a filter (10) which retains the solid matter
