Heating Element Air Flow Path for Cigarette Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional heaters for non-burning smoking articles with central heating methods result in uneven heating of cigarettes, leading to incomplete baking of the peripheral areas and affecting smoke yield and user taste.
Innovation Solution
A heating element with an air flow path and strategically positioned air holes that allow external air to flow through, preheating the cigarette evenly by diffusing heat from the core area, preventing overheating and ensuring consistent flavor and aerosol production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If central heating method is used, then heating efficiency at core area is improved, but heating uniformity deteriorates
Solution Approach 1:
The heating element is segmented into multiple independent heating zones along its length, with each zone capable of localized heating. This segmentation allows heat to be distributed to both core and peripheral areas of the cigarette simultaneously, resolving the contradiction between concentrated heating efficiency and overall heating uniformity.
Solution Approach 2:
Different sections of the heating element are designed with different heating characteristics - the core area provides intense localized heating while peripheral areas provide gentler heating. This local quality differentiation enables each zone to perform its specific heating function optimally, achieving both high heating efficiency at the core and uniform overall heating.
2Speed
If heat is concentrated on core area, then heating speed at core is improved, but peripheral area heating completeness deteriorates
Solution Approach 1:
The heating element is divided into multiple heating zones that operate simultaneously, with faster heating at the core and progressive heating at peripheral zones. This segmentation allows the system to maintain high heating speed at the core while ensuring complete heating at peripheral areas through coordinated multi-zone operation.
Solution Approach 2:
The heating element employs periodic or staged heating activation across different zones, where core heating activates first for rapid temperature rise, followed by sequential activation of peripheral heating zones. This periodic action ensures both rapid initial heating and complete eventual heating of all areas.
