Solution Overview

Problem

Cigar enthusiasts seek custom tobacco blends and rolling experiences that ready-made cigars cannot provide, leading to a demand for customizable tobacco products that allow users to create their own cigars with specific tobacco blends.

Innovation Solution

The development of pre-rolled sheets made from cellulose and tobacco materials, which can be laminated and packaged with a form casing, enabling users to disassemble and refill to create custom cigars, with options for transparency, adhesive layers, and inclusion of flavoring agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If ready-made cigars are used, then convenience is improved, but customization capability deteriorates

Engineering Contradiction:
ImproveconvenienceVSAvoidcustomization capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The cigar is divided into separate components: a reusable cellulose wrapper shell and refillable tobacco filler. This segmentation allows the wrapper to be kept and reused while the tobacco can be replaced with custom blends, combining the convenience of pre-made cigars with the customization of hand-rolling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cellulose wrapper is pre-formed and prepared in advance as a reusable shell. Users only need to refill the tobacco component, eliminating the time-consuming process of manually rolling the wrapper while maintaining full customization of the tobacco blend.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If custom blending is allowed, then product versatility is improved, but device complexity deteriorates

Engineering Contradiction:
Improveproduct versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By separating the wrapper shell from the tobacco filler, the system simplifies the customization process. Users only need to handle the tobacco refill portion while the pre-formed cellulose shell remains a simple reusable container, reducing the complexity involved in achieving custom blends.

Inventive Principle:
Principle #1Segmentation

3Illumination intensity

If transparent sheets are used, then visual appeal is improved, but material complexity deteriorates

Engineering Contradiction:
Improvevisual appealVSAvoidmaterial complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The cellulose wrapper can be produced in different optical properties including transparent, translucent, or opaque versions. This allows consumers to choose their preferred visual appearance while the underlying cellulose material and manufacturing process remain fundamentally the same, avoiding excessive material complexity.

Inventive Principle:
Principle #32Color changes

AI summary

A smoking article provides one or more sheets of material that can be rolled and packaged, at least one sheet including cellulose. In one embodiment, cellulose and tobacco sheet material are separately rolled layers that can optionally be wrapped around a form casing (or pre-rolled inside) and then packaged. In another embodiment, the sheet is a laminated sheet of tobacco and cellulose layers that can be optionally wrapped around (or pre-rolled inside) a form casing. These sheets can be filled with custom tobacco to make one or more new cigars for an end user. In another embodiment, a complete cigar filled with tobacco material can be disassembled by an end user to produce tobacco and cellulose sheets, enabling the end user to form two new cigars using his or her own custom tobacco.
