Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional combustion methods are used to vaporize aerosol precursor compositions, then vaporization can be achieved, but significant combustion and pyrolysis products are delivered which are harmful
Solution Approach 1:
The patent replaces thermal combustion mechanisms with ultrasonic vibration mechanisms. The atomization assembly uses ultrasonic vibrating elements to mechanically vibrate and atomize the aerosol precursor composition, eliminating the need for high-temperature combustion while achieving effective vaporization. This substitution of mechanical energy for thermal energy resolves the contradiction by avoiding combustion products while maintaining vaporization capability.
Solution Approach 2:
The patent utilizes phase transition through ultrasonic vibration to convert liquid aerosol precursor composition into aerosol. The ultrasonic vibration causes rapid oscillation and cavitation in the liquid, creating fine droplets and vapor without requiring high-temperature combustion. This phase transition mechanism achieves vaporization while avoiding the harmful combustion byproducts that would result from thermal decomposition.
2Productivity
If a single atomization assembly is used, then the device structure is simple, but aerosol generation efficiency and functionality are limited
Solution Approach 1:
The patent divides the atomization function into multiple separate atomization assemblies within the single device. Each assembly contains its own vibrating elements and can independently atomize aerosol precursor composition. This segmentation increases overall aerosol generation efficiency and provides functional versatility while maintaining a manageable device structure through modular design.
Solution Approach 2:
The patent designs the atomization assemblies with universal applicability, where multiple assemblies can be configured to handle different aerosol precursor compositions and delivery requirements. The standardized design allows the same basic atomization unit to serve multiple functions - different flavors, concentrations, and delivery rates - thereby increasing productivity without proportionally increasing device complexity.
3Ease of operation
If mesh plates are arranged in specific configurations, then aerosol delivery is optimized, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different mesh plate configurations and orientations to different locations within the atomization assemblies based on local functional requirements. Rather than requiring uniform high-precision manufacturing throughout, each mesh plate is specifically designed and positioned to optimize aerosol delivery for its particular function - such as different angles for different flavor profiles or concentrations. This localized optimization reduces overall manufacturing precision requirements while maintaining excellent aerosol delivery performance.
