Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage pools lack efficient mechanisms to alternately operate water circulation and water massage functions without causing undesired flow splitting and air retention, which can lead to operational inefficiencies and potential failure of temperature sensors.
Innovation Solution
A control box with a filtering pump unit, massage pump unit, three-way connecting pipe fitting, and swing check one-way valves to alternately open and close flow paths, ensuring seamless operation between filtration and massage modes while preventing air retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If water circulation and water massage functions share a common water outlet pipe without flow control mechanisms, then device complexity is reduced, but flow splitting occurs causing operational inefficiency and air retention
Solution Approach 1:
The patent divides the common water outlet system into separate flow paths using a three-way connecting pipe fitting. This segmentation allows independent control of filtration and massage water flows, preventing flow splitting while maintaining manageable system complexity through modular valve integration.
Solution Approach 2:
The patent introduces swing check one-way valves as intermediary components in each flow path. These valves act as mediators that automatically control water flow direction based on pressure differentials, ensuring reliable flow path selection without requiring complex active control mechanisms.
2Reliability
If independent water conduits are used for filtration and massage systems, then flow control reliability is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent merges the filtration and massage water conduits into a single control box assembly with integrated pump units, pipe fittings, and valve mechanisms. This consolidation maintains reliable flow control through proper segmentation while reducing the overall space occupation compared to completely separate systems.
Solution Approach 2:
The patent employs a nested arrangement where the three-way connecting pipe fitting and swing check valves are integrated within the control box structure, with pipes and components arranged in compact, space-efficient configurations that nest functional elements together.
3Ease of manufacture
If simple pipe connections are used without flow control valves, then ease of manufacture is improved, but air retention occurs leading to temperature sensor failure
Solution Approach 1:
The patent employs swing check one-way valves that automatically control flow direction based on pressure differentials without requiring external control systems. This self-service mechanism prevents air retention and ensures proper water flow through the temperature sensor region while maintaining relatively simple assembly procedures.
4Productivity
If alternating operation of filtration and massage pumps is implemented without flow control, then productivity is improved, but flow splitting causes operational inefficiency
Solution Approach 1:
The patent implements dynamic flow path control where swing check valves automatically adjust water flow direction based on which pump (filtration or massage) is currently operating. This dynamic response ensures complete flow path isolation and prevents flow splitting, maintaining high productivity through efficient alternating operation.
