Massage Pool Airway Structure With Elastic Sealing Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage pool airway structures experience air leakage due to loosening of the tight fit between the control plate and the peripheral ring over long-term use, leading to inefficiencies in air charging and exhausting.
Innovation Solution
The airway structure incorporates a pipeline with a fixed air connection portion, a control valve group, an air connection sleeve, a first elastic body, and a second elastic body, ensuring the air connection sleeve is always tightly fitted with the control plate through the elastic bodies, allowing for compensation and stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional control plate is rotatably connected to the air connection port, then the air charging and exhausting function is achieved, but air leakage occurs due to loosening of the tight fit between the control plate and peripheral ring over long-term use
Solution Approach 1:
The patent introduces elastic bodies (springs) to create a dynamic compensation mechanism that automatically adjusts to maintain sealing pressure. The elastic bodies are pre-compressed to exert continuous force on the control plate and air connection sleeve, ensuring they remain tightly pressed against their respective sealing surfaces even after long-term use when loosening occurs. This dynamic force compensation resolves the contradiction between initial sealing performance and long-term durability.
Solution Approach 2:
The elastic bodies are pre-compressed during assembly to store elastic potential energy, creating a beforehand cushioning force that proactively compensates for future loosening. The pre-compression ensures that the control plate and air connection sleeve are always under sufficient pressing force to maintain sealing, preventing air leakage before it can occur during operation.
2Reliability
If the control plate is tightly fitted to the peripheral ring, then sealing is improved, but the switching force becomes difficult to apply and the perception of correct switching positions is reduced
Solution Approach 1:
The elastic bodies provide a dynamic balance between sealing force and switching ease. During normal operation, the elastic force maintains tight sealing. During switching, when external force is applied to rotate the control plate, the elastic bodies compress further, allowing the control plate to overcome the sealing force temporarily. The abutting areas provide tactile feedback that helps users perceive correct switching positions without requiring excessive force.
Solution Approach 2:
The patent introduces abutting areas on the control plate that are specifically designed to be pressed by the air connection sleeve during switching. These localized abutting areas concentrate the switching force, making it easier to rotate the control plate while maintaining sealing at other critical interfaces. This local quality differentiation resolves the contradiction between overall tight fitting and ease of switching operation.

Function Achieved in This Case
This design effectively prevents air leakage, enhances the sealing mechanism, and simplifies assembly, providing reliable compensation and improved user experience by reducing switching force and enhancing the perception of correct switching positions.
Implementation Method 1
The first elastic body is attached between the pipeline and the control valve group and abuts against the control valve group to make the control plate abut under the sealing plate
Implementation Method 2
The second elastic body is mounted between the air connection portion and the air connection sleeve and abuts against the air connection sleeve to make the air connection sleeve abut under the control plate
