Solution Overview
Problem
Existing aerosol-generating systems lack user control flexibility and often result in undesirable parameter combinations, limiting user preferences and potentially causing system damage.
Innovation Solution
A method and device for controlling an electrically operated aerosol-generating system that allows users to adjust multiple parameters within allowable ranges, with interdependent parameters adjusted based on user input, using look-up tables and algorithms to prevent mutually exclusive settings, and providing confirmation options for user satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to freely adjust system parameters, then user control flexibility is improved, but undesirable parameter combinations may occur causing system damage
Solution Approach 1:
The system dynamically adjusts the range of allowable values for parameters based on the current state of other parameters. When a user modifies one parameter, the system automatically recalculates and updates the acceptable ranges for related parameters, ensuring that no unsafe parameter combinations can be achieved while maintaining user flexibility within safe operating boundaries.
Solution Approach 2:
The system provides feedback to users about the consequences of parameter adjustments by displaying updated allowable ranges. This feedback mechanism informs users of the interdependencies between parameters and the potential impacts of their choices, enabling informed decision-making while preventing unsafe configurations.
2Reliability
If the range of allowable values for parameters is fixed, then system safety is maintained, but user control flexibility is limited
Solution Approach 1:
The system transitions from static, fixed parameter ranges to dynamic, adaptive ranges that automatically adjust based on current operating conditions. The allowable value ranges are continuously updated according to the actual state of system parameters, enabling users to explore a broader range of configurations while maintaining safety through real-time validation.
3Ease of operation
If multiple parameters are adjusted simultaneously, then user convenience is improved, but mutually exclusive parameter settings may occur
Solution Approach 1:
The system performs preliminary validation and calculation of parameter interactions before allowing adjustments to be applied. When users modify parameters, the system pre-calculates the implications for other parameters and updates allowable ranges in advance, preventing mutually exclusive settings from being imposed on the user.
Solution Approach 2:
The system introduces an intermediary control layer that mediates between user input and actual parameter settings. This intermediary layer processes user requests, validates them against current system state, and translates them into compatible parameter adjustments, filtering out mutually exclusive combinations before they can cause system errors.
