Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the user determines baking completion through taste, then the device structure remains simple, but the baking precision deteriorates leading to overbaking or underbaking

Engineering Contradiction:

Improvebaking degree detection accuracyVSAvoiddevice structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/sensory method of taste-based baking assessment with an electrical measurement system. Electrical conductors are embedded in the heating element to detect electrical parameters (resistance, current, voltage) that correlate with the physical state of the aerosol-forming article during heating, enabling objective detection of baking completion without complex mechanical sensors or user subjectivity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces electrical parameters as an intermediary indicator between the heating process and baking completion determination. Instead of directly measuring physical or chemical properties of the aerosol-forming article, the system uses changes in electrical parameters (affected by temperature, moisture content, and material degradation) as indirect but reliable indicators of baking state

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the aerosol-forming article is overbaked, then the baking time is extended, but harmful factors increase resulting in burnt taste and smoke reduction

Engineering Contradiction:

Improvevaporization efficiencyVSAvoidburnt taste and smoke

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent implements a feedback control mechanism where electrical parameters detected during heating are continuously monitored and compared against predetermined thresholds. When the electrical parameter indicates that the aerosol-forming article has reached optimal baking completion, the system automatically stops heating, preventing overbaking and the associated harmful effects of burnt taste and smoke generation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent establishes predetermined electrical parameter thresholds that correspond to optimal baking completion points for different types of aerosol-forming articles. By pre-setting these reference values, the system is prepared to immediately recognize and respond to baking completion, preventing the progression to overbaking before harmful effects occur

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If the aerosol-forming article is underbaked, then the baking time is reduced, but loss of substance increases causing waste and poor user experience

Engineering Contradiction:

Improvebaking timeVSAvoidaerosol-forming article waste

Core Design Contradiction:

Loss of timeVSLoss of substance

Solution Approach 1:

The continuous monitoring of electrical parameters provides real-time feedback on the baking process, ensuring that heating continues until the predetermined threshold is reached. This prevents premature termination of baking that would result in underbaked articles and waste, while still minimizing unnecessary extended heating time

Inventive Principle:

Principle #23Feedback
