Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat-not-burn devices face issues with complex and easily damaged pushing mechanisms for separating cigarettes from heating elements, and peripheral heating that is inefficient due to distance from the cigarette center.
Innovation Solution
An electromagnetic heat-not-burn device with a magnetic induction coil and a rotating body heating element structure, where the heating element includes a non-susceptive support column and a metal susceptor tube, allowing for efficient heating and easy separation of the cigarette without a separate removal mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pushing mechanism is designed to separate the cigarette from the heating sheet, then the cigarette can be separated after heating, but the mechanism becomes complex and easily damaged after repeated use
Solution Approach 1:
The patent removes the pushing mechanism entirely by extracting the separation function from the heating element design. The heating element is made non-stick through material selection and surface treatment, allowing cigarettes to be easily removed without any mechanical pushing device, thus eliminating complexity while maintaining ease of operation
Solution Approach 2:
The heating element surface is designed to be non-stick through its material properties (PTFE coating or similar non-adhesive material), enabling the cigarette to separate automatically after heating without requiring any additional mechanism. The surface properties themselves provide the separation function
2Device complexity
If a heating pipe is used for peripheral heating, then the heating structure is simple, but the heating effect is poor because it is far away from the center of the cigarette
Solution Approach 1:
The patent transitions from peripheral heating (heating from the outside surface) to central heating (heating from the center axis). The heating element is positioned at the center of the cigarette, heating it from the inside out, which ensures uniform and efficient heating while maintaining structural simplicity
Solution Approach 2:
The heating function is concentrated at the critical location (center of the cigarette) where it is most needed. The heating element is specifically positioned to contact the center of the cigarette, providing localized intensive heating that ensures complete combustion while keeping the overall structure simple
3Reliability
If a heating sheet is inserted into the cigarette, then heating can be achieved, but the cigarette easily sticks to the heating sheet requiring a pushing mechanism
Solution Approach 1:
The patent eliminates the need for separation mechanisms by extracting the sticking problem through material selection. The heating element uses non-stick materials (such as PTFE coating) that prevent adhesion between the heated cigarette and the heating surface, allowing easy removal without any additional mechanism
Solution Approach 2:
The patent replaces the mechanical pushing system with a material-based solution. Instead of using mechanical forces to separate the cigarette through a pushing mechanism, the solution uses the non-stick properties of the heating element material to prevent adhesion in the first place, eliminating the need for mechanical separation
