Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes lack dose control, allowing users to vape freely without quantifiable limits, which can lead to overuse and potential health hazards, especially when using vaporized liquid medicine.
Innovation Solution
An electronic cigarette with dose control capabilities, featuring a housing, liquid storage chamber, vaporizing device, battery, airflow sensor, and control circuit, which includes a microcontroller, power control unit, timing unit, energy statistics and conversion unit, and indication unit. The system calculates electric energy consumption and converts it into a dose of consumed cigarette liquid, providing alerts when a preset dose threshold is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic cigarettes allow free use without dose control, then user convenience and ease of operation are improved, but health safety and reliability deteriorate due to potential overuse and harmful effects
Solution Approach 1:
The patent implements a feedback mechanism where the control circuit continuously monitors the cumulative dose of vaporized liquid through the energy statistics and conversion unit, compares it against preset thresholds, and provides real-time feedback to the user via the indication unit (display, buzzer, or vibrator). This feedback loop enables dose control while maintaining user convenience, resolving the contradiction between ease of operation and health safety.
2Reliability
If electronic cigarettes implement dose control mechanisms, then health safety and reliability are improved, but device complexity increases due to additional control circuits and monitoring components
Solution Approach 1:
The control circuit is designed to perform multiple functions: it controls power supply to the heating unit, monitors energy consumption, calculates cumulative dose, compares against thresholds, and provides user feedback through multiple indication methods. By making the control circuit multi-functional, the patent reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while maintaining health safety through dose control.
3Measurement precision
If electronic cigarettes calculate and monitor energy consumption to determine dose, then measurement precision of vapor dose is improved, but use of energy increases due to continuous monitoring and calculation operations
Solution Approach 1:
The patent implements preliminary action by presetting dose thresholds and measurement parameters in the control circuit before actual use. The system pre-configures the conversion relationships between energy consumption and vapor dose, allowing the monitoring process to simply retrieve and compare pre-calculated values rather than performing complex real-time calculations. This approach improves measurement precision while minimizing additional energy consumption during operation.
