Single-Pump Water Distribution for Walk-In Tub Multi-Function Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current walk-in bathtubs require separate pumps for whirlpool, micro nano bubbles, and rapid water discharge systems, which are expensive and lack sufficient space for components and plumbing under the bathtub.
Innovation Solution
A reconfigurable water distribution system utilizing a single pump and motorized valves to manage multiple functions, such as water jets, micro-nano bubbles, and rapid water discharge, through a network of pipes and valves controlled by an electronic controller unit, allowing for selection of functions via user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate pumps are used for whirlpool, micro nano bubbles, and rapid water discharge systems, then each function can be independently operated, but the cost increases and space requirements are not met
Solution Approach 1:
A single pump system is designed to perform multiple functions (whirlpool, micro nano bubbles, and rapid water discharge) by incorporating motorized valves that can direct water flow to different outlets based on user selection, eliminating the need for separate pumps for each function
Solution Approach 2:
The system uses motorized valves that can dynamically redirect water flow between different functions based on operational mode, allowing one pump to adaptively serve multiple purposes rather than requiring static dedicated pumps for each function
2Adaptability or versatility
If separate pumps are used for each function, then functional independence is achieved, but the cost increases
Solution Approach 1:
Multiple pump functions are merged into a single pump system with integrated motorized valve control, reducing the total number of pumps from three to one and thereby lowering manufacturing and installation costs while maintaining functional independence through electronic control
3Adaptability or versatility
If separate pumps and components are installed for each function, then complete functionality is provided, but available space under the bathtub is insufficient
Solution Approach 1:
A single pump with multi-position motorized valves provides complete functionality for all three systems (whirlpool, micro nano bubbles, rapid discharge) in one compact unit, reducing the space requirement from three separate pump installations to one consolidated system that fits within the limited under-tub compartment

AI summary
A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.
