Solution Overview

Problem

Conventional vaporizers for aromatherapy often suffer from inefficient heat management, residue buildup, and odor issues due to combustion byproducts and sticky fluid pathways, which affect performance and user experience.

Innovation Solution

A rechargeable, portable convection vaporizer with a concentrating furnace and temperature control system that uses heated air to vaporize essential oils and plant materials without combustion, featuring a removable and reusable fluid pathway and material chamber to manage odor and residue effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If combustion is used to vaporize plant materials, then vaporization temperature is achieved, but combustion byproducts and odor are generated

Engineering Contradiction:

Improvevaporization temperatureVSAvoidcombustion byproducts and odor

Core Design Contradiction:

TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful combustion process into a beneficial convection heating process. Instead of burning plant materials directly (combustion), the system heats air separately and uses the heated air to vaporize essential oils and plant materials indirectly (convection). This eliminates combustion byproducts and unpleasant odors while maintaining effective vaporization temperatures.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent introduces heated air as an intermediary medium between the heat source and the plant materials. The heating element heats air in a furnace, and this heated air then passes through the plant material chamber to vaporize the materials without direct contact between the heat source and materials, preventing combustion and harmful byproducts.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If fixed fluid pathway is used, then device structure is simplified, but residue buildup and odor issues occur

Engineering Contradiction:

Improvedevice structureVSAvoidresidue buildup and odor

Core Design Contradiction:

Device complexityVSObject-generated harmful factors

Solution Approach 1:

The patent segments the vaporizer into distinct removable components: a heating system with furnace, a material chamber, and a fluid pathway assembly. The fluid pathway can be removed separately from the heating system, allowing users to clean or replace it independently. This segmentation prevents residue buildup in the fluid pathway while maintaining relatively simple overall device structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent enables the fluid pathway to be discarded (removed and cleaned or replaced) independently from the main heating system. Users can remove the fluid pathway component to clean residue or replace it entirely, while retaining the valuable heating system. This approach addresses odor and residue issues without requiring complete device replacement or complex disassembly.

Inventive Principle:

Principle #34Discarding and recovering

3Object-generated harmful factors

If convection heating system is used, then combustion byproducts are eliminated, but temperature control complexity increases

Engineering Contradiction:

Improvecombustion byproductsVSAvoidtemperature control system

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent incorporates a temperature sensor that continuously monitors the temperature in the furnace and provides feedback to the control circuit. The control circuit adjusts the heating element power accordingly to maintain the desired temperature range, enabling precise temperature control for convection heating while eliminating combustion byproducts through controlled heating rather than uncontrolled combustion.

Inventive Principle:

Principle #23Feedback

AI summary

Disclosed herein are aspects of portable vaporizers and isolated vapor dispensers wherein material in the vapor dispenser is placed in the fluid pathway of heated air from a convection heat source such as a furnace. A printed circuit board in signal communications with temperature sensor controls the temperature produced by heating elements in the furnace. A rechargeable battery power supply is mounted in a body to supply power the heating element. The vapor dispenser is removable and may be disposable. A smell reducing accessory module reversibly mates with the body of the vaporizer.
