Inflatable Massage Pool Inlet Assembly With Shared Water Paths
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 arrangement.
Innovation Solution
A single water inlet pipe with a water flow guiding device that overlaps filtered and massage water flows, using a retractable pipe and elastic member to switch between flows, reducing the need for multiple welds and simplifying pipeline arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate inlet and outlet pipes are used for massage and filtered water circulation systems, then each system can operate independently, but the number of welding points increases and pipeline arrangement becomes complex
Solution Approach 1:
The patent combines the filtered water inlet pipe and massage water inlet pipe into a single shared inlet passage that passes through the pool wall once. Inside the pool, the pipes are partially overlapped and positioned at different heights, allowing both circulation systems to share the same wall penetration point while maintaining independent water flow paths.
Solution Approach 2:
The shared inlet pipe structure serves dual functions: it provides the inlet for both the filtered water circulation system and the massage water circulation system. This multi-functional design eliminates the need for separate wall penetrations while maintaining independent operation of both systems.
2Reliability
If separate inlet and outlet pipes are used for massage and filtered water circulation systems, then each system has dedicated piping, but manufacturing cost increases due to multiple welding points
Solution Approach 1:
The patent merges the wall penetration function for both inlet pipes into a single shared inlet structure. This reduces the number of welding points on the pool wall from two separate connections to one shared connection, thereby reducing manufacturing complexity and cost while maintaining dedicated piping paths inside the pool.
3Ease of operation
If separate outlet pipes are used for filtered and massage water, then water flows can be independently controlled, but the pool wall requires multiple penetration points increasing structural complexity
Solution Approach 1:
The patent applies the same merging principle to outlet pipes as to inlet pipes. The filtered water outlet pipe and massage water outlet pipe are positioned at different heights but share the same general outlet structure, reducing the number of wall penetrations required while maintaining independent flow control capability.

Function Achieved in This Case
Reduces manufacturing costs and simplifies pipeline arrangement by minimizing welds while maintaining effective water circulation for both massage and filtration functions.
Implementation Method 1
an elastic member, disposed inside the housing chamber and between the fixed portion and the retractable portion
Implementation Method 2
the retractable pipe is movable between an extended state and a retracted state

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.
