Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating products for heated cigarettes face challenges in achieving uniform heating, leading to reduced smoke volume and fragrance quality, and the cigarette core sticks are often too hard, prone to deformation and breakage during processing.
Innovation Solution
The aerosol generating product incorporates a smoke producing pipe with a tobacco substance, porous material, fragrance enhancing substance, smoke producing substance, supporting fiber, and adhesive, allowing for efficient smoke generation through afterheat and providing a flexible structure to prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the heater axial length is made consistent with the tobacco stick axial length to guarantee uniform heating, then the heating uniformity is improved, but the heater design flexibility and adaptability are reduced
Solution Approach 1:
The tobacco stick is divided into multiple sections with different materials and functions: the upstream section contains tobacco powder for smoke generation, the downstream section contains tobacco sheet for fragrance enhancement, and intermediate sections contain supporting fibers and porous materials. This segmentation allows different regions to serve different purposes while maintaining overall heating uniformity without requiring the heater to match the entire tobacco stick length.
Solution Approach 2:
Different sections of the tobacco stick are assigned different material properties and functions. The upstream section uses tobacco powder for efficient smoke generation, while the downstream section uses tobacco sheet for fragrance release. This local differentiation allows each section to be optimized for its specific function while the overall structure maintains heating uniformity.
2Manufacturing precision
If the cigarette core stick hardness is increased to prevent deformation during cutting, then the cutting stability is improved, but the brittleness increases and breakage becomes more likely during filling and packing
Solution Approach 1:
The tobacco stick employs a composite structure combining multiple materials: tobacco powder, tobacco sheet, supporting fibers (such as cellulose or acetate fibers), and porous materials. This composite structure provides both the rigidity needed for stable cutting and the flexibility required to prevent breakage during subsequent processing, resolving the contradiction between cutting stability and breakage resistance.
Solution Approach 2:
The tobacco stick incorporates flexible supporting fibers and thin film structures that provide structural integrity during cutting while maintaining enough flexibility to prevent brittle breakage during filling and packing operations. The fibrous structure acts as a flexible reinforcement within the composite material.
3Quantity of substance
If the tobacco sheet is arranged on the downstream of the tobacco section to release smoke through afterheat, then the smoke volume is expected to increase, but the smoke volume decreases and fragrance quality is reduced due to smoke being held back by the tobacco sheet
Solution Approach 1:
The invention incorporates porous materials in the tobacco stick structure that facilitate smooth smoke flow and prevent smoke accumulation. The porous structure allows smoke to pass through efficiently without being held back, while still enabling the tobacco sheet to release fragrance through controlled porosity, thus increasing smoke volume without compromising fragrance quality.
Solution Approach 2:
The invention introduces intermediate materials such as porous materials and supporting fibers between the tobacco powder section and tobacco sheet section. These intermediary materials act as conduits that facilitate smooth smoke transition and prevent smoke accumulation, allowing the tobacco sheet to release fragrance without blocking smoke flow, thereby resolving the contradiction between smoke volume and fragrance quality.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables increased smoke volume and improved fragrance quality by utilizing the porous material to adsorb and release fragrance and smoke producing substances, while the supporting fiber ensures the cigarette core stick remains flexible and resistant to breakage.

AI summary
The present invention discloses an aerosol generating product suitable for heaters with different lengths, including a smoke producing pipe; the smoke producing pipe includes a tobacco substance and/or a porous material, a fragrance enhancing substance and/or a smoke producing substance, a supporting fiber and an adhesive; and an aerosol generating apparatus matching with the aerosol generating product has a heater, and an axial length of the heater is less than or equal to an axial length of the smoke producing pipe. The aerosol generating product of the present invention is suitable for the heaters with the different lengths, as in the smoke producing pipe of the present invention, the fragrance enhancing substance and/or the smoke producing substance are/is only adsorbed to the porous material, the fragrance enhancing substance and/or the smoke producing substance in a cigarette core stick in a region not covered with the heater can be released only through heat conducted by hot smoke, and thus the effects of fragrance enhancing and increasing the smoke volume are achieved.
