Solution Overview

Problem

Existing humidifiers with scent-generating capabilities are limited by the need for separate electrical heating elements, which increase complexity and cost, and lack independent operation of scent and humidification components, often resulting in unsightly clutter and inefficient scent diffusion.

Innovation Solution

A humidifier design where a heat source, such as a motor or water heater, is thermally coupled with a scent-releasing element, allowing the scent pad to harness excess heat without a separate electrical heating element, enabling independent operation and reduced energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a dedicated electrical heating element is used to heat the scent mechanism, then the scent can be effectively dispersed, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvescent heating temperatureVSAvoidheating system complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the scent heating function with the humidifier's existing heating system. The scent pad is positioned in thermal contact with the heating element that also heats water for humidification, allowing one heating system to serve dual purposes: generating humidity and dispersing scent without requiring a separate dedicated heater.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating element is designed to perform multiple functions simultaneously - it serves as both the water heater for humidification and the scent warmer. This multi-functional approach eliminates the need for separate heating components while maintaining effective scent dispersion capability.

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

2Temperature

If a separate electrical heating element is added to the scent mechanism, then the scent diffusion effectiveness improves, but the manufacturing cost increases

Engineering Contradiction:
Improvescent heating temperatureVSAvoidmanufacturing cost
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The patent combines the scent heating function with the existing humidifier heating element, eliminating the need for additional heating components. This integration reduces part count, simplifies assembly, and lowers manufacturing costs while maintaining effective scent diffusion capability.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the humidifier and air freshener are integrated with independent operation, then the device versatility improves, but the device complexity increases

Engineering Contradiction:
Improveindependent operation capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the device into functionally independent modules - the humidification system and the scent dispersion system can operate independently or together. The scent pad holder is designed as a separate removable component that can be installed or removed based on user needs, allowing flexible operation modes without complex electronic controls.

Inventive Principle:
Principle #1Segmentation

4Productivity

If the scent pad is continuously exposed to air, then the scent diffusion is maximized, but the scent releases continuously even when not needed

Engineering Contradiction:
Improvescent diffusion rateVSAvoidscent release control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements a dynamic scent pad holder that can be adjusted between different exposure positions. The holder allows the scent pad to be positioned at various angles and degrees of exposure, enabling users to control the scent release rate from minimal to maximum based on their preferences and environmental conditions.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

AI summary

A portable appliance includes a humidifier and a heated scent mechanism. The heated scent mechanism includes a scent generator that harvests excess heat produced by a liquid heating chamber, or heat produced as a byproduct of motor operation. The humidifier may be controllable such that the appliance can serve as either a humidifier or air- freshener, individually or simultaneously.
