Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-rolled cigarettes, cigars, and cigarillos lack integrated filters made from hazardous synthetic materials, and adding flavors is difficult, posing health risks and limited options for smokers.
Innovation Solution
A hollow elongated member with a filter assembly and flavor carrier holder structure, using natural materials like Cordia or Areca leaves and husks, which can be rolled into a tube with a filter element and flavor carrier, allowing for a safer and flavorful smoking experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic filter materials (cellulose acetate, rayon) are used in hand-rolled cigarettes, then filter structure is provided, but health hazards increase due to burning synthetic fibers
Solution Approach 1:
The patent changes the material parameter from synthetic (cellulose acetate, rayon) to natural plant-based materials (Cordia leaf, Areca husk). This parameter change eliminates the health hazards associated with burning synthetic fibers while maintaining the filter's structural function. The natural materials are processed into a compacted form that provides effective filtration without the harmful byproducts of synthetic material combustion.
Solution Approach 2:
The patent employs composite material construction by combining Cordia leaf material with Areca husk in the filter assembly. This composite approach creates a synergistic effect where the natural plant materials work together to provide both structural integrity and filtration capability, while eliminating the need for hazardous synthetic fibers. The composite natural material structure achieves reliable filtering function without health risks.
2Device complexity
If traditional hand-rolled cigarettes are used without integrated filters, then simplicity is maintained, but smoke quality and flavor options are limited
Solution Approach 1:
The patent merges the filter function and flavor delivery system into a single integrated assembly that is incorporated into the hand-rolled cigarette. The filter assembly combines natural filtering material with a flavor carrier holder structure, creating a unified component that simultaneously improves smoke quality and provides flavor options without significantly increasing overall device complexity. This merged structure maintains the simplicity of hand-rolled cigarettes while adding enhanced functionality.
Solution Approach 2:
The filter assembly serves multiple functions: it filters the smoke, provides structural support, and delivers flavor through the integrated flavor carrier. This multi-functional design allows a single component to address multiple needs (filtration, structure, flavoring) that would traditionally require separate elements, thereby improving smoke quality and flavor options while maintaining relative simplicity.
3Object-affected harmful factors
If natural plant materials (Cordia leaf, Areca husk) are used for the filter assembly, then health safety and aesthetics are improved, but manufacturing complexity increases due to dual material holder structure
Solution Approach 1:
The patent employs a nested structure where the flavor carrier holder is positioned within or alongside the natural plant material filter body. The holder structure is integrated into the overall filter assembly, with the natural materials forming the outer structure and the holder providing internal support for the flavor carrier. This nested arrangement manages the complexity of multiple materials by organizing them in a hierarchical, space-efficient configuration that maintains health safety and aesthetics while controlling manufacturing complexity.
4Adaptability or versatility
If flavors are added to hand-rolled cigarettes using traditional methods, then flavor options are provided, but integration difficulty and smoke quality degradation occur
Solution Approach 1:
The patent incorporates the flavor carrier into the filter assembly during the manufacturing process, before the cigarette is rolled and used. The flavor carrier is pre-positioned within the holder structure, and the entire assembly is prepared in advance. This preliminary action eliminates the need for complex integration steps during or after cigarette rolling, as the flavor delivery system is already integrated into the filter assembly. The flavor options are provided through this pre-integrated structure without adding significant manufacturing complexity.

AI summary
A device for burning smoking material and inhaling the resulting smoke is disclosed. The device can include an elongated member having an internal elongated cavity extending from a first end to a second end along a central axis. The device can include a filter assembly disposed in the elongated member. The filter assembly can comprise a first filter section adjacent to the first end and a second filter section between the first filter section and the second end. A holder structure is disposed between the first filter element and the second filter element. The holder structure comprises a holder element having an inner space and a holder wrapper surrounding the holder element. The holder element and holder wrapper can be formed of dissimilar materials. A flavor carrier containing a flavoring agent is disposed within the inner space.
