Solution Overview

Problem

Existing evaporators for essential oils are difficult to clean and maintain due to their one-piece design, which hampers efficient evaporation and requires cumbersome handling of the oil container.

Innovation Solution

A modular evaporator design featuring a housing with a removable container, a heat transfer mechanism using a metal heat conductive material, and a retaining mechanism involving a magnet for secure and efficient heat transfer, along with temperature control and a rechargeable battery for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a one-piece ceramic evaporator design is used, then the structure is simple and easy to manufacture, but the container is difficult to clean and maintain

Engineering Contradiction:
Improveease of manufactureVSAvoidease of cleaning
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The evaporator is divided into separate components: a removable container (15) and a housing (2) with a receiving recess (14). The container can be detached from the housing, allowing easy access for cleaning and maintenance while keeping the overall structure relatively simple for manufacturing.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a removable container design is used, then the container is easy to clean and replace, but the engagement and retention mechanism becomes complex

Engineering Contradiction:
Improveease of cleaningVSAvoidcomplexity of retention mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The retaining means (48) uses magnetic attraction instead of complex mechanical fasteners, clips, or screws to secure the container (15) in the receiving recess (14). This magnetic retention system simplifies the overall mechanism while ensuring secure engagement and easy removal.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Use of energy by moving object

If a heat transfer means is introduced, then heat transfer efficiency is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoidcomplexity of heat transfer mechanism
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

A heat transfer means (30) made of heat-conductive material is introduced as an intermediary component between the heating means (25) and the container (15). This intermediate element improves thermal coupling and heat transfer efficiency while maintaining a relatively simple overall structure through direct thermal contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An evaporator (1) comprises a housing (2) having a top wall (7) in which a receiving recess (14) is formed for receiving a container (15) for a liquid to be evaporated. A heat transfer element (30) having a first heat transfer abutment face (35) located in the receiving recess (14) transfers heat from an electrically powered heating element (25) to the container (15) through a second heat transfer abutment face (36) of a base (16) of the container (15). The heating element is planar and is located between the heat transfer element (30) and a locating element (40), which retains the heating element (25) tightly between the heat transfer element (30) and the locating element (40). A retaining magnet (48) located in the locating element (40) extends into a bore (52) in the heat transfer element (30) and co-operates with a complementary element (49) of magnetic material located in the base (16) of the container (15) for releasably retaining the container (15) in the receiving recess (14).
