Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If substrate configuration is optimized, then smoking taste is improved, but other factors affecting smoking taste are not addressed

Engineering Contradiction:
Improvesubstrate configurationVSAvoidcomprehensive smoking taste optimization
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent segments the smoking taste optimization into multiple independent factors: substrate configuration, heating temperature, puff timing, and puff interval. Each factor can be independently optimized and adjusted based on user behavior history, allowing comprehensive improvement beyond just substrate configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts puff timing and heating parameters based on real-time user behavior history and feedback. The control unit modifies operational parameters adaptively rather than using fixed settings, enabling the system to optimize smoking taste across multiple varying factors simultaneously.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple parameters are adjusted to improve smoking taste, then user experience is enhanced, but device complexity increases

Engineering Contradiction:
Improvesmoking taste qualityVSAvoidcontrol mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements feedback loops where user behavior history (actual puff timings and intervals) is continuously monitored and fed back to the control unit. This feedback enables automatic adjustment of puff timing recommendations and heating parameters, achieving complex multi-parameter optimization through a centralized intelligent control system rather than multiple independent mechanisms.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control unit autonomously analyzes user behavior patterns and self-adjusts operational parameters without requiring manual intervention. The system serves itself by automatically optimizing puff timing, heating temperature, and other parameters based on accumulated user data, reducing the need for complex user interfaces or manual calibration mechanisms.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If puff timing is optimized based on user behavior history, then smoking taste is improved, but data collection and processing requirements increase

Engineering Contradiction:
Improvepersonalized puff timingVSAvoiduser behavior data
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary analysis of user behavior history to pre-calculate optimal puff timing recommendations before the user actually puffs. By anticipating user preferences based on past behavior patterns, the system prepares optimization parameters in advance, reducing the need for extensive real-time data processing and minimizing information loss.

Inventive Principle:
Principle #10Preliminary action

AI summary

[Problem] To provide a mechanism capable of further improving the quality of the user experience. [Solution] A terminal device comprising a control unit that sets, based on the user's behavior history, a first puff timing, which is the timing at which the user should inhale an aerosol generated by an inhalation device that heats an aerosol source contained in a substrate to generate the aerosol, and controls a process of notifying the user of information indicating the set first puff timing.
