Solution Overview

Problem

Existing saunas require users to manually set up and adjust settings each time they use them, offering little variation in the experience and lacking seamless integration with user preferences and data across different facilities.

Innovation Solution

A sauna system with communication and control circuitry that links to a remote server, allowing user profiles, preferences, and usage information to be shared across a network of saunas, enabling seamless access to personalized features and data tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If saunas are stand alone and locally controlled, then each user can independently control sauna features, but users must manually set up and adjust settings each time they use the sauna, resulting in repetitive experience and lack of seamless integration across facilities

Engineering Contradiction:
Improveease of useVSAvoidtime to set up and adjust settings
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

User profiles, preferences, and usage information are pre-stored on a remote server. When a user accesses a sauna, the system automatically retrieves and applies their preferred settings in advance, eliminating the need for manual setup during each session.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A remote server acts as an intermediary between users and multiple sauna devices. The server stores user profiles and facilitates automatic configuration across different sauna locations, enabling seamless experience without direct user intervention at each device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If saunas are stand alone and locally controlled, then each sauna operates independently, but moving to a different sauna device requires adjusting settings from what a prior user had selected, resulting in repetitive experience

Engineering Contradiction:
Improveconsistency across facilitiesVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The remote server provides universal access to user profiles across multiple sauna devices and facilities. A single user profile can be applied at any connected sauna, making the system universally adaptable to different locations while maintaining consistent user experience.

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

Solution Approach 2:

The system automatically retrieves user profile information from the remote server and applies it to the current sauna device. This feedback mechanism ensures that settings are automatically adjusted based on user preferences without requiring manual intervention, providing consistent experience across facilities.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If traditional saunas provide television or music playback features, then entertainment is available, but such traditional programming often actually detracts from the sauna experience

Engineering Contradiction:
Improvepersonalization of experienceVSAvoiddetrimental effect on sauna experience
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The sauna system dynamically adjusts entertainment features based on user preferences stored in their profile. Rather than providing fixed traditional programming, the system adapts media playback, lighting, and other features to match individual user choices, allowing users to control the level and type of entertainment without defaulting to potentially detrimental traditional programming.

Inventive Principle:
Principle #15Dynamics

AI summary

A sauna having a video display device, a loud speaker device, lighting elements, an aromatherapy device, and a user interface device, and includes control circuitry which links the sauna to a remote server. The remote server provides media files for display to a user and collects and stores user profile and usage information. Multiple saunas are be linked into a network or global infrastructure so that a user's profile and usage information follow the user to any sauna connected to the network. Collected data can be used by users to track individual usage and performance metrices, and by service providers to analyze usage data and information for operational and marketing purposes.
