Heat-Not-Burn Cap Position Detection for Heater Power Cutoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-not-burn smoking substitute systems lack effective mechanisms to ensure user safety and efficiency by preventing accidental exposure to the heating element and optimizing power usage.
Innovation Solution
A heat-not-burn device with a movable cap that detects its position to control power supply to the heating element, ensuring it is only activated when the cap is engaged and deactivated when disengaged, thereby preventing user exposure and conserving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nicotine is delivered through the heating element, then the user receives the desired effect, but the heating element becomes coated with residue and degrades
Solution Approach 1:
A filter component is introduced as an intermediary between the liquid reservoir and heating element. This filter captures nicotine and other substances from the vaporized liquid before they reach the heating element, preventing coating and degradation while still allowing controlled delivery of nicotine to the user.
Solution Approach 2:
The filter selectively extracts and removes nicotine and harmful residues from the vapor stream before it contacts the heating element. This extraction process protects the heating element material from degradation while maintaining the therapeutic effect for the user.
2Reliability
If the device heats the liquid to vaporize nicotine, then nicotine delivery is achieved, but harmful byproducts are generated
Solution Approach 1:
The filter is designed to capture harmful heating byproducts and residues that would otherwise be inhaled by the user. By converting these harmful substances into captured particulates on the filter, the system maintains effective nicotine delivery while eliminating or reducing harmful exposures.
3Productivity
If the wick delivers liquid to the heating element, then vaporization is enabled, but the wick becomes coated and delivery becomes erratic
Solution Approach 1:
The filter acts as an intermediary that prevents coated residue from reaching and contaminating the wick material. This maintains stable wick composition and consistent liquid delivery rates throughout the product lifecycle.
