Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the voltage or power outputted by the power supply component increases and the resistance of the heating element becomes smaller, then the heating efficiency and atomization effect are improved, but the temperature of the heating element becomes excessively high causing harmful substances to be released
Solution Approach 1:
The patent implements a temperature detection module that continuously monitors the heating element temperature and feeds this information back to the control device. The control device compares the detected temperature with pre-stored temperature variation parameters and adjusts the power output accordingly, reducing power when temperature exceeds safe thresholds to prevent harmful substance release while maintaining heating efficiency within safe operating ranges.
Solution Approach 2:
The patent stores multiple temperature variation parameters corresponding to different temperature variation curves in the storage module. The control device dynamically selects and adjusts power output parameters based on the detected temperature and the specific liquid solution type, changing operational parameters in real-time to optimize heating efficiency while preventing excessive temperature rise that would cause harmful emissions.
2Ease of operation
If different types of liquid solutions are used with different ingredients, then the atomization temperatures corresponding to optimum smoking feelings vary, but a fixed heating control cannot achieve optimal atomization for all liquid solution types
Solution Approach 1:
The patent creates a universal heating control system that can adapt to multiple types of liquid solutions with different ingredients. The storage module pre-stores temperature variation parameters for various liquid solution types, and the control device automatically selects the appropriate parameters based on detection, enabling a single device to achieve optimal atomization across different liquid compositions without requiring manual adjustment or multiple specialized devices.
Solution Approach 2:
The patent implements dynamic heating control where the power output is continuously adjusted based on the detected liquid solution type and real-time temperature feedback. Unlike fixed heating systems, this dynamic approach allows the control device to modify heating parameters on-the-fly to match the specific thermal characteristics of each liquid solution type, achieving optimal atomization feelings for diverse ingredients.
3Measurement precision
If a temperature detection module and control module are added to monitor and control heating temperature, then the temperature control precision is improved, but the device complexity increases
Solution Approach 1:
The patent implements a self-service control mechanism where the control device automatically compares detected temperature parameters with pre-stored reference parameters and adjusts power output without requiring external intervention or complex control algorithms. The system serves itself by using pre-programmed temperature variation curves for different liquid types, simplifying the control logic while maintaining high temperature precision through automated feedback and adjustment.
