Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual temperature adjustment of electronic cigarettes is tedious and leads to poor user experience, as different tobacco liquids require varying heating temperatures for optimal atomization.
Innovation Solution
An electronic cigarette system that identifies the type of tobacco liquid using a dielectric constant sensor and matches it with pre-stored values to determine the appropriate temperature settings, allowing the device to automatically adjust its heating based on preset temperature information, such as time-dependent or fixed temperature curves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual temperature adjustment is used, then device complexity is reduced, but ease of operation deteriorates due to tedious adjustment process
Solution Approach 1:
The electronic cigarette system automatically identifies the tobacco liquid type through dielectric constant detection and self-adjusts the heating temperature without requiring manual user intervention. The controller autonomously completes the entire process from liquid identification to temperature parameter adjustment, making the system serve itself rather than requiring continuous user input.
Solution Approach 2:
The patent replaces manual mechanical temperature adjustment with an automated electronic control system. The controller uses dielectric constant sensing and automated programming to determine optimal heating parameters, substituting the mechanical act of manual adjustment with an electronic decision-making and control system.
2Ease of operation
If automated temperature control is implemented, then ease of operation is improved, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The controller serves multiple functions: it controls the heating element for atomization, operates the dielectric constant sensor for liquid identification, stores liquid type information in memory, and automatically adjusts heating parameters. By consolidating these diverse functions into a single control unit, the patent reduces the need for separate dedicated components for each function.
Solution Approach 2:
The dielectric constant sensor acts as an intermediary that indirectly identifies tobacco liquid type without requiring direct physical contact or complex analysis. The sensor measures the electrical property (dielectric constant) of the liquid, providing the controller with sufficient information to identify the liquid type and adjust temperature accordingly, simplifying the overall detection mechanism.
3Productivity
If manual temperature adjustment is used, then device complexity is reduced, but productivity deteriorates due to time-consuming adjustments
Solution Approach 1:
The system pre-stores dielectric constant values and corresponding heating temperature parameters for multiple tobacco liquid types in the controller's memory. When a new liquid is detected, the controller quickly compares the measured dielectric constant against the pre-stored values and immediately retrieves the appropriate heating parameters, eliminating the need for time-consuming manual adjustment processes.
Solution Approach 2:
The system implements a feedback loop where the controller continuously monitors the dielectric constant of the tobacco liquid and automatically adjusts the heating temperature based on the detected liquid type. This closed-loop control ensures optimal atomization temperature is maintained without requiring user intervention, significantly improving operational efficiency.
