Solution Overview

Problem

Existing cigarette butt collection methods, such as those using bag-type structures, are inconvenient and do not adequately address the issue of safely and cleanly accommodating cigarette butts, leading to environmental pollution and health hazards.

Innovation Solution

A cigarette butt collection wrapping material using a multi-layer paper sheet, comprising a metal sheet layer, adhesive layers, and paper sheet layers, designed to ensure easy accommodation, flame retardancy, and sealability, with a structure that allows easy opening and handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a bag-type structure is used for cigarette butt collection, then the collection function is provided, but the ease of operation deteriorates due to difficult accommodation and sealing

Engineering Contradiction:
Improveease of accommodation and sealingVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wrapping material is divided into multiple functional layers (first paper sheet layer, metal sheet layer, second paper sheet layer) with distinct roles. The first paper sheet layer provides ease of opening and handling, the metal sheet layer provides flame retardancy and sealing, while the second paper sheet layer provides structural support. This segmentation allows each layer to optimize its specific function without compromising overall operability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses a composite structure combining different materials (paper and metal) bonded together through adhesive layers. The paper layers provide flexibility and ease of operation, while the metal layer provides flame retardancy and sealability. This composite material approach resolves the contradiction by integrating the advantages of different materials to simultaneously achieve ease of operation and functional performance.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If flame retardancy is ensured through metal sheet layer, then fire prevention is improved, but the device complexity increases due to multi-layer structure

Engineering Contradiction:
Improvefire preventionVSAvoidmulti-layer structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Flame retardancy is localized to the metal sheet layer, which is positioned specifically within the multi-layer structure where it is most needed for fire prevention. The paper layers maintain their traditional properties for ease of handling, while the metal layer provides targeted flame retardancy. This local quality approach ensures fire prevention without requiring the entire structure to be complex or rigid.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The combination of paper and metal layers creates a composite material structure where each material contributes its superior properties. The metal sheet layer provides flame retardancy and sealing capability, while the paper layers provide flexibility and ease of operation. The adhesive layers bond these materials together into an integrated structure that achieves both fire prevention and operational simplicity.

Inventive Principle:
Principle #40Composite materials

3Reliability

If multi-layer structure is used for flame retardancy and sealability, then reliability is improved, but the ease of manufacture deteriorates

Engineering Contradiction:
Improveflame retardancy and sealabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple functional requirements (flame retardancy, sealability, ease of opening, structural support) are merged into a single integrated multi-layer wrapping material. The first paper sheet layer, metal sheet layer, and second paper sheet layer are bonded together through adhesive layers to form one unified product that performs all necessary functions simultaneously, simplifying the overall manufacturing process despite the multi-layer structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The composite material structure allows different materials to be manufactured separately and then bonded together using standard adhesive techniques. This approach maintains reliability through material selection (metal for flame retardancy, paper for flexibility) while facilitating manufacturing through modular assembly of pre-manufactured layers.

Inventive Principle:
Principle #40Composite materials

AI summary

A cigarette butt collection wrapping material using a multi-layer paper sheet, according to the present disclosure, enables cigarette butts to be safely wrapped and cleanly accommodated, and enables the occurrence of fire caused by cigarette butts to be prevented by having sufficiently ensured flame retardancy. In addition, the cigarette butt collection wrapping material according to the present disclosure is easily opened through a method for pressing the top edge portions of the left and right sides of the wrapping material, so that an opening may be formed, thereby enabling cigarette butts to be easily accommodated therein, and is thin such that a plurality thereof may be joined and easily separated one at a time and used and is easy to carry. Specifically, a cigarette butt collection bag according to the present disclosure may prevent cigarette butts from being thrown out illegally by improving bad smoking patterns in which the light of a cigarette is tapped or snubbed out and the cigarette butt is thrown out after smoking, may establish a culture of safely wrapping, cleanly accommodating and collecting cigarette butts, and may contribute to rendering of cigarette butts into resources through recycling.
