Solution Overview

Problem

Existing therapy systems, such as saunas and cold plunge tubs, lack an efficient and seamless transition between hot and cold therapy experiences, often requiring separate setups and inconvenient user access.

Innovation Solution

A combined therapy system integrating a sauna and a cold plunge tub, allowing for a seamless transition between hot and cold therapy experiences by positioning the tub below the sauna, with a removable cover for easy access and a spray assembly for fluid delivery from multiple angles, controlled by a unified control system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate therapy systems (sauna and cold plunge tub) are used, then each system can provide dedicated therapy experience, but transition between hot and cold therapy is inconvenient and requires separate setups

Engineering Contradiction:
Improvetransition convenienceVSAvoidsystem integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines a sauna and cold plunge tub into a single integrated therapy system. The cold plunge tub is positioned inside the sauna chamber, allowing both hot and cold therapy experiences to be accessed from one location. This merging eliminates the need to travel between separate systems and enables seamless transition between therapy modes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cold plunge tub is nested within the sauna chamber structure. The tub is positioned on the floor of the sauna, with the sauna's heating elements and chamber walls surrounding the tub. This nesting arrangement allows the system to occupy minimal space while providing both hot and cold therapy functions in a compact configuration.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Loss of time

If bathtub is positioned inside interior chamber, then quick transition between hot and cold therapy is enabled, but access to bathing volume may be restricted

Engineering Contradiction:
Improvetransition timeVSAvoidaccessibility
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system incorporates a removable cover or lid for the cold plunge tub, allowing the bathing volume to be accessible when needed while maintaining a closed configuration during storage or non-use. This dynamic adjustment enables easy access to the tub interior without compromising the compact nested arrangement.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If spray assembly is added for fluid delivery, then comprehensive therapy experience is provided, but device complexity increases

Engineering Contradiction:
Improvetherapy optionsVSAvoidassembly components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spray assembly is designed to serve multiple functions: delivering water for cold plunge therapy, providing steam for sauna therapy, and potentially offering massage functions. By making the spray system multi-functional, the patent reduces the need for separate components for different therapy modes, thereby limiting the increase in overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A therapy system includes a first therapy assembly configured to provide a hot therapy experience and a second therapy assembly configured to provide a cold therapy experience. The first therapy assembly includes a plurality of walls defining an interior chamber, a door configured to permit selective access to the interior chamber, and a sauna element fluidly coupled with the interior chamber and configured to provide at least one of heated air or steam to the interior chamber. The second therapy assembly includes a bathtub defining a bathing volume structured to receive and hold a fluid. The bathtub is positioned relative to the interior chamber of the first therapy assembly such that the bathing volume is accessible from the interior chamber of the first therapy assembly.
