Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aerosol delivery systems generate aerosol with consistent characteristics to maintain user experience, then user satisfaction is improved, but resource consumption (power, aerosolisable material) increases

Engineering Contradiction:

Improveuser experience consistencyVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making aerosol characteristics adjustable rather than fixed. The controller dynamically modifies aerosol parameters (particle size, density, constituent proportions) based on usage patterns and conditions, allowing the system to adapt between delivering consistent high-quality aerosol and conserving resources when full consistency is not critical

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by varying aerosol characteristics (particle size distribution, density, temperature, constituent proportions) according to different usage scenarios. This allows the system to optimize between user experience consistency and resource consumption by adjusting parameters rather than maintaining fixed settings

Inventive Principle:

Principle #35Parameter changes

2Productivity

If aerosol delivery systems use higher power to generate aerosol, then aerosol generation speed is improved, but device usage time decreases

Engineering Contradiction:

Improveaerosol generation speedVSAvoiddevice usage time

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent applies periodic action by varying power delivery in cycles or intervals rather than continuously at maximum level. The controller can alternate between high-power bursts for rapid aerosol generation and lower-power intervals for conservation, optimizing both generation speed and overall usage duration

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts power consumption based on real-time conditions and usage patterns, allowing high productivity when needed while extending overall device usage time through adaptive power management

Inventive Principle:

Principle #15Dynamics

3Reliability

If aerosol delivery systems consume more aerosolisable material to maintain consistent characteristics, then aerosol quality is improved, but material replenishment frequency increases

Engineering Contradiction:

Improveaerosol quality consistencyVSAvoidaerosolisable material consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent changes aerosol parameters (particle size, density, temperature, constituent proportions) to achieve quality consistency more efficiently. By optimizing these parameters, the system maintains reliable aerosol quality while consuming less aerosolisable material, reducing replenishment frequency

Inventive Principle:

Principle #35Parameter changes

4Use of energy by moving object

If aerosol delivery systems generate aerosol with modified characteristics to save resources, then resource consumption is reduced, but user perception of change increases

Engineering Contradiction:

Improvepower consumptionVSAvoiduser perception of aerosol change

Core Design Contradiction:

Use of energy by moving objectVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies local quality by making specific, targeted modifications to aerosol characteristics rather than broad changes. The controller adjusts particular parameters (particle size distribution, temperature, constituent proportions) in controlled ways that achieve resource savings while maintaining user-perceived quality in the most critical aspects

Inventive Principle:

Principle #3Local quality
