Inflatable Massage Pool Water Inlet Assembly for Fewer Wall Welds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separation of massage and filtered water circulation systems in inflatable massage pools requires separate inlet and outlet pipes, leading to increased manufacturing costs and complexity due to multiple welding points and difficult pipeline arrangements.
Innovation Solution
A water inlet assembly with a water flow guiding device that overlaps filtered and massage water inlet pipes, allowing both flows to be directed into a single water receiving cavity through a retractable pipe system, reducing the need for multiple welds and simplifying pipeline arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate inlet pipes are used for massage water circulation system and filtered water circulation system, then each system can operate independently, but the number of welding points on the pool wall increases and pipeline arrangement becomes more complex
Solution Approach 1:
The patent combines the filtered water inlet pipe and massage water inlet pipe into a single integrated water inlet assembly. The assembly includes a common inlet passage that receives both filtered water and massage water, then distributes them through separate internal channels to their respective systems. This merging approach reduces the number of welding points on the pool wall from two separate connections to one unified connection, while maintaining the independent operation capability of both circulation systems through internal flow separation.
Solution Approach 2:
The water inlet assembly is designed as a multi-functional component that serves both the filtered water circulation system and the massage water circulation system simultaneously. The single assembly incorporates multiple inlet passages, flow distribution channels, and connection interfaces that enable it to handle different water flows for different purposes. This universal design eliminates the need for separate dedicated inlet pipes while ensuring each system receives its required water flow independently.
2Reliability
If separate inlet pipes are used for massage water circulation system and filtered water circulation system, then each system has dedicated water flow paths, but manufacturing cost increases due to multiple welding points
Solution Approach 1:
The patent merges two separate inlet pipe installations into one integrated water inlet assembly, directly reducing the number of welding operations required on the pool wall. By consolidating the connection points from two separate pipes to one unified assembly, manufacturing costs are reduced due to fewer welding tasks, less material usage, and simplified installation procedures, while the assembly internally maintains dedicated flow paths for each system.
Solution Approach 2:
The universal water inlet assembly design allows a single component to replace two separate pipe systems, reducing overall manufacturing complexity and cost. The assembly incorporates multiple functional channels within a single structure, enabling it to serve both circulation systems simultaneously while requiring only one welding connection to the pool wall, thereby achieving cost efficiency without sacrificing system reliability.
3Ease of operation
If two separate inlet pipes are welded to the pool wall, then each system has its own water inlet, but the number of welding points increases leading to higher installation difficulty
Solution Approach 1:
The patent combines the installation of two separate inlet pipes into a single integrated water inlet assembly installation. The assembly includes all necessary internal passages and distribution channels pre-configured to serve both the filtered water system and massage water system. This merging reduces the installation process from welding and positioning two separate pipes to welding and positioning one unified assembly, significantly reducing installation difficulty and time while maintaining adequate water inlet provision for both systems.

AI summary
An inflatable massage pool comprises a pool body defining an inflatable cavity and a water receiving cavity. A water inlet assembly, located in the inflatable cavity, is configured to provide one of a filtered water flow or a massage water flow to the water receiving cavity. The water inlet assembly includes a water inlet pipe and a water flow guiding device. The water inlet pipe has a water inlet passage in fluid communication with the water flow guiding device for delivering one of the filtered water flow or the massage water flow to the water receiving cavity. The water inlet passage and the water flow guiding device delivers the massage water flow and the filtered water flow into the water receiving cavity in different paths or the same path, thereby reducing welding points on a pool wall, lowering the manufacturing cost, and reducing the difficulty in pipeline arrangement.
