Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high-viscosity aerosol-forming materials are used, then the material can be delivered to users, but the fluidity becomes poor leading to liquid guiding obstruction

Engineering Contradiction:

Improveaerosol-forming material deliveryVSAvoidfluidity

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent changes the temperature parameter of the aerosol-forming material by introducing a thermal conduction layer that heats the material. This temperature increase reduces the viscosity and improves fluidity, allowing high-viscosity materials to flow properly through the liquid guiding assembly without obstruction.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The thermal conduction layer acts as an intermediary between the heating element and the aerosol-forming material. It transfers heat from the heating element to the material, enabling temperature-controlled viscosity adjustment without direct contact between the heating element and the material.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If high-viscosity aerosol-forming materials are used, then the material can be delivered, but ventilation bubbles flow is impeded causing blockage

Engineering Contradiction:

Improveaerosol-forming material deliveryVSAvoidventilation bubble blockage

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

By increasing the temperature of the aerosol-forming material through the thermal conduction layer, the viscosity is reduced. This parameter change allows ventilation bubbles to flow more freely through the liquid guiding assembly, preventing blockage and ensuring proper ventilation.

Inventive Principle:

Principle #35Parameter changes

3Use of energy by moving object

If thermal conduction layer is in direct contact with heating element, then heat transfer is efficient, but liquid guiding obstruction occurs

Engineering Contradiction:

Improveheat transfer efficiencyVSAvoidliquid guiding fluidity

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The isolation layer serves as an intermediary between the heating element and the thermal conduction layer. It prevents direct contact while allowing heat transfer, thus avoiding liquid guiding obstruction caused by direct heating element contact while maintaining thermal efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the heating structure into distinct functional layers: the heating element, the isolation layer, and the thermal conduction layer. This segmentation allows each layer to perform its specific function independently, preventing direct contact issues while maintaining heat transfer efficiency.

Inventive Principle:

Principle #1Segmentation

4Ease of operation

If isolation layer is added between thermal conduction layer and heating element, then liquid guiding obstruction is prevented, but heat transfer is reduced

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The isolation layer is designed with specific local properties (thickness, material composition) that optimize the balance between preventing direct contact and allowing heat transfer. The local quality of the isolation layer ensures minimal thermal resistance while maintaining the protective function.

Inventive Principle:

Principle #3Local quality
