Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional outer wrapping paper made from hemp pulp and fillers is used, then the structure provides mechanical strength and wrapping function, but it absorbs a lot of infrared rays which reduces the heating efficiency of internal tobacco products
Solution Approach 1:
The patent applies porous materials by forming a porous coating layer on the inner surface of the wrapping paper. This porous structure allows infrared radiation to pass through more effectively while maintaining the mechanical integrity of the wrapping paper, thus reducing infrared absorption and improving heating efficiency.
Solution Approach 2:
The patent uses composite materials by combining wrapping paper with a specifically designed porous coating layer. This composite structure leverages the mechanical strength of the paper and the infrared-transmissive properties of the porous coating, resolving the contradiction between strength and infrared absorption.
2Temperature
If the wrapping paper absorbs infrared rays, then it provides thermal insulation, but it affects the temperature rise rate and preheating time of the aerosol-forming matrix
Solution Approach 1:
The porous coating layer reduces infrared absorption and facilitates faster heat transfer to the aerosol-forming matrix, thereby increasing the temperature rise rate and reducing preheating time.
Solution Approach 2:
The patent changes the physical and chemical parameters of the wrapping paper surface by applying a porous coating with specific pore size, porosity, and thermal conductivity values optimized for rapid infrared transmission and heat transfer.
3Productivity
If the wrapping paper is made with fillers like calcium carbonate, then it improves the paper properties, but it increases infrared absorption which reduces aerosol generation efficiency
Solution Approach 1:
The porous coating layer is designed to minimize infrared absorption and maximize heat transfer to the aerosol-forming matrix, thereby improving aerosol generation efficiency without relying on traditional fillers that absorb infrared radiation.
Solution Approach 2:
The patent optimizes the porosity, pore size, and thermal conductivity parameters of the coating layer to enhance infrared transmission and heat transfer efficiency, directly improving aerosol generation productivity.
