Pool Sprayer Air-Water Mixture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool sprayers often fail to provide a comfortable and effective massage experience due to either strong or insufficient water force, which does not cater to individual user preferences.
Innovation Solution
A pool sprayer system that combines an outlet module for spraying water with a suction module for ambient air, connected by a pipe, allowing for adjustable air-water mixture delivery, enabling users to control the force and comfort of the water spray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If existing sprayers spray water with strong force, then massaging effect is achieved, but comfort against user's skin deteriorates
Solution Approach 1:
The patent applies parameter changes by mixing air with water to alter the physical properties of the spray. The air-water mixture changes the density and force characteristics of the spray, enabling adjustable spray intensity that provides massaging effect while reducing skin discomfort through customizable parameters.
Solution Approach 2:
The patent introduces air as an intermediary substance mixed with water before delivery. This air-water mixture acts as a mediator that softens the direct water impact on skin while maintaining sufficient force for massaging, thereby resolving the contradiction between force and comfort.
2Object-affected harmful factors
If existing sprayers spray water with weak force, then skin comfort is improved, but massaging effect deteriorates
Solution Approach 1:
The patent implements dynamics through adjustable spray mechanisms that allow users to dynamically change spray intensity. The system can adapt between gentle and strong spray modes, providing both skin comfort and massaging effect depending on user needs, rather than being fixed at a single force level.
Solution Approach 2:
By changing the air-to-water ratio and spray pressure parameters, the system achieves variable spray force. This parameter adjustment capability enables the sprayer to deliver both comfortable gentle sprays and effective strong massaging sprays, resolving the contradiction between comfort and massaging effect.
3Device complexity
If a pool sprayer provides fixed water spray, then device simplicity is maintained, but user preference adaptability deteriorates
Solution Approach 1:
The patent achieves multi-functionality by incorporating both water delivery and air mixing capabilities into a single sprayer unit. This universal design allows the device to provide multiple spray modes (gentle and strong) to accommodate different user preferences, thereby improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The patent uses pneumatic principles by introducing air into the water stream to create an air-water mixture. This pneumatic-hydraulic system enables adjustable spray characteristics through air-to-water ratio control, providing adaptability to different user preferences while maintaining relatively simple device structure through fluid dynamics rather than complex mechanical adjustments.

AI summary
A sprayer (3) configured to provide an air-water mixture to a pool or spa. The sprayer includes an outlet module (32) for spraying an air-water mixture into a water cavity of the pool, a suction module (34) for suctioning ambient air into the outlet module, and a connecting pipe (36) that connects the outlet module and the suction module. The sprayer may be concealed within an inflatable chamber of the pool.
