Solution Overview

Problem

Existing evaporation devices for volatile substances are ineffective in regulating the evaporation rate and fragrance intensity due to mechanical movements that can damage electrical components and increase complexity and cost.

Innovation Solution

A device with a static heater and a movable evaporation rate regulator connected to a rotating disc, allowing linear movement to adjust the air flow area around the wick, thus regulating evaporation rate and fragrance intensity without moving the heater.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the heater is moved with respect to the wick to regulate evaporation rate, then the evaporation rate can be changed, but the electrical components may be damaged and the device complexity increases

Engineering Contradiction:
Improveevaporation rateVSAvoidelectrical component durability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Instead of moving the heater to regulate evaporation rate, the patent moves the regulator (outlet channel) relative to the stationary heater. This inversion of which component moves resolves the contradiction by protecting electrical components from damage while still enabling evaporation rate control through regulator positioning at different distances from the heater.

Inventive Principle:
Principle #13The other way round (Inversion)

2Productivity

If the heater is moved with respect to the wick to regulate evaporation rate, then the evaporation rate can be changed, but the device complexity and cost increase due to longer cables

Engineering Contradiction:
Improveevaporation rateVSAvoidcable length and assembly complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent inverts the conventional approach by making the regulator movable and the heater stationary. This eliminates the need for long cables and complex assembly, as the regulator can be positioned at different distances from the fixed heater to control evaporation rate without requiring extensive cable lengths or complex mounting mechanisms.

Inventive Principle:
Principle #13The other way round (Inversion)

3Productivity

If a rotating part blocks direct exposure between the wick and heater, then the evaporation rate can be reduced, but the regulation effectiveness is insufficient

Engineering Contradiction:
Improveevaporation rateVSAvoidregulation effectiveness
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements a dynamic regulator that can be positioned at different distances from the heater through rotation, rather than simply blocking exposure. The regulator's outlet channel is elongated and can be oriented to control air flow dynamics, providing more effective and continuous evaporation rate regulation compared to static blocking mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The regulator functions as a pneumatic control element, using air flow through its outlet channel to regulate evaporation. By positioning the regulator at different distances from the heater and orienting its channel, it controls the air flow dynamics directly around the wick, providing effective evaporation rate control through fluid dynamics rather than simple mechanical blocking.

Inventive Principle:
Principle #29Pneumatics and hydraulics
