Solution Overview

Problem

Conventional bath systems lack efficient separation and circulation of hot and cold water, leading to temperature mixing and inconsistent user experience, which hampers therapeutic benefits like contrast bath therapy.

Innovation Solution

A bath system with separate hot and cold water zones, each equipped with a whirlpool system and a heating or cooling element, is designed with a partition to maintain water temperature consistency and prevent mixing, using opposing water flow directions to keep temperatures distinct.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single basin with mixed hot and cold water is used, then the device complexity is reduced, but the temperature consistency and therapeutic effectiveness deteriorate

Engineering Contradiction:
Improvebath system structureVSAvoidwater temperature consistency
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

The bath system is divided into separate basins (first basin for hot water, second basin for cold water) with distinct whirlpool systems, heating elements, and cooling elements. This segmentation maintains temperature consistency in each basin while providing therapeutic contrast therapy, resolving the contradiction between simplicity and temperature control.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If hot and cold water are allowed to mix freely, then the ease of operation is improved, but the therapeutic effectiveness deteriorates

Engineering Contradiction:
Improvewater flow controlVSAvoidtherapeutic effect reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Each basin is equipped with localized temperature control elements (heating element in first basin, cooling element in second basin) and separate whirlpool systems that create opposing flow directions. This ensures each basin maintains its intended temperature regime for reliable contrast therapy while remaining easy to operate.

Inventive Principle:
Principle #3Local quality

3Temperature

If separate basins with opposing whirlpool systems are used, then the temperature separation is improved, but the device complexity increases

Engineering Contradiction:
Improvehot and cold water separationVSAvoidwhirlpool and temperature control systems
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into integrated systems: each basin has a combined whirlpool system with heating or cooling elements, and both basins share a common water inlet and drain structure. This merging approach achieves effective temperature separation while managing device complexity through functional integration.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

A bath receptor includes a first basin, a second basin, and a partition positioned between the first basin and the second basin. The first basin includes a first whirlpool system configured to direct water in a first rotational direction within the first basin. The second basin includes a second whirlpool system configured to direct water in a second rotational direction within the second basin. The second rotational direction is opposite the first rotational direction. The partition is physically coupled to the first basin and the second basin.
