Solution Overview

Problem

Existing methods for making cigarettes are not efficient in filling smoking material into cigarette tubes and do not provide a convenient way to create a filtered cigarette.

Innovation Solution

A kit comprising a foldable funnel and a pre-rolled cigarette tube, where the funnel is used to fill the tube with smoking material and can be rolled into a filter for smoke filtration when the cigarette is ignited.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing methods are used to make cigarettes, then the process is simple, but the filling efficiency is low and convenience is poor

Engineering Contradiction:

Improvefilling efficiencyVSAvoidkit structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The funnel is designed to serve multiple functions: it acts as a filling tool to insert smoking material into the cigarette tube, and can be rolled into a filter that is then inserted into the cigarette tube. This multi-functionality improves filling efficiency and convenience without requiring separate devices for each operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The kit is divided into distinct components (cigarette tube, funnel, filter) that can be assembled in a convenient sequence. The funnel is provided in a flat configuration that is easy to handle and fold, segmenting the complex task of cigarette making into manageable steps.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If a filter is added to the cigarette tube, then smoke filtration is improved, but the device complexity increases

Engineering Contradiction:

Improvesmoke filtrationVSAvoidcigarette structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The funnel serves dual purposes: first as a filling instrument, then as the source material for the filter. By rolling the funnel into a filter and inserting it into the cigarette tube, the system provides smoke filtration without requiring a completely separate filter component, thus improving filtration while minimizing additional structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The filling operation and filter creation are merged into a single integrated process using the same funnel component. The funnel is used to fill the tube with smoking material, then rolled into a filter and inserted into the tube, combining multiple functions into one element.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Kit for producing a cigarette includes a cigarette tube holding a smoking material, a funnel having a length, a top face, a bottom face, and funnel includes a fold line along which bottom face of funnel is folded relative to the top face to form a slot and a closed bottom face. The funnel receives the smoking material through the slot and fills the funnel with smoking material for filling the cigarette tube. The cigarette tube is filled with the smokable material. The funnel is rollable into a filter, and the filter is inserted into an end of the cigarette tube, and the filter filters smoke from the smoking material and the cigarette tube when the cigarette tube and the smoking material are ignited. There is likewise a method of making a cigarette using the kit.
