Solution Overview

Problem

Conventional sauna apparatuses fail to achieve uniform temperature and humidity distribution, leading to discomfort and limitations in usage, such as preventing users from reading due to mist on glasses and difficulty in controlling environmental conditions.

Innovation Solution

A sauna apparatus with integrated heating and humidifying sections that mix heated and humidified air to ensure uniform temperature and humidity, featuring a merging chamber to combine air streams and a water-shattering section to produce fine water droplets for efficient humidification, allowing for easy control of temperature and humidity levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heated air and mist are blown separately, then the heating and humidifying functions can be performed, but the temperature and humidity distribution becomes non-uniform

Engineering Contradiction:
Improvetemperature distributionVSAvoidair mixing structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent combines the heated air blowing function and humidified air blowing function into a single outlet structure. The merging chamber integrates both air streams before discharge, ensuring uniform mixing of heated and humidified air. This resolves the technical contradiction by achieving uniform temperature and humidity distribution without requiring separate outlets or complex mixing structures.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If mist is spouted separately from heated air, then humidification can be achieved, but water droplets adhere to user's glasses and cause discomfort

Engineering Contradiction:
Improvewater droplet adhesionVSAvoidair mixing structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the heated air stream and humidified air stream in a common merging chamber before discharge through a single outlet. This integration ensures that water droplets are properly mixed and distributed with the heated air, preventing them from adhering to the user's glasses. The unified outlet structure eliminates the harmful effect of separate mist spouting while maintaining simple device architecture.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If separate blowing sections are used for heated air and humidified air, then independent control is possible, but overall temperature and humidity control becomes difficult

Engineering Contradiction:
Improvetemperature and humidity controlVSAvoidcontrol system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the control of heated air blowing and humidified air blowing into a unified system through the merging chamber. By integrating both air streams before discharge, the control system can easily adjust overall temperature and humidity levels through a single coordinated mechanism. This resolves the contradiction by achieving easy environmental control without requiring complex independent control systems for separate outlets.

Inventive Principle:
Principle #5Merging (Combining)
