Rotatable Jet Aerator Nozzle for Adjustable Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hot tub and spa jets lack adjustable and efficient mechanisms for directing water and air streams, limiting user control over the flow and direction of jets.
Innovation Solution
A jet aerator system with a rotatable exit nozzle and jet cover assembly, featuring lock clips, locking tabs, stabilizing tabs, and a dual-locking mechanism, allows for adjustable alignment of water and air apertures with conduits, enabling precise control over the water and air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional jets use fixed spray patterns, then the structure is simple, but user control over flow direction is limited
Solution Approach 1:
The jet aerator employs a rotatable jet cover and rotatable exit nozzle that can be independently adjusted to different angular positions. The jet cover rotates about the longitudinal axis of the jet body, while the exit nozzle rotates about its own axis, enabling dynamic adjustment of spray patterns and flow directions to suit user preferences
Solution Approach 2:
The jet aerator is divided into multiple independently adjustable segments: the jet cover with its aperture pattern, the exit nozzle with its alignment aperture, and the rotatable mechanisms connecting them. This segmentation allows each component to be adjusted independently, providing fine-grained control over water and air flow directions without requiring complete redesign of the entire jet structure
2Adaptability or versatility
If the exit nozzle is made rotatable for adjustment, then user flexibility is improved, but the nozzle may become loose or misaligned
Solution Approach 1:
The jet cover includes pre-formed locking tabs that engage with corresponding slots in the jet body, and the exit nozzle includes locking tabs that engage with slots in the jet cover. These locking features are built into the structure beforehand, ensuring that when the rotatable components are adjusted to desired positions, they automatically lock into place to maintain alignment stability
Solution Approach 2:
The jet cover serves as an intermediary component between the fixed jet body and the rotatable exit nozzle. It provides a stable mounting surface with locking slots that secure the exit nozzle at adjusted positions, while itself being secured to the jet body through its own locking mechanism, thus mediating between the stationary and movable elements
3Measurement precision
If multiple adjustment mechanisms are added, then control precision is improved, but the device becomes more complex
Solution Approach 1:
The jet cover and exit nozzle adjustment mechanisms are merged into a coordinated system where the jet cover rotation adjusts the overall spray direction, and the exit nozzle rotation fine-tunes the aperture alignment. The locking tabs and slots on both components work together as an integrated adjustment system, providing precise control without requiring separate adjustment mechanisms for each function
