Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disposal of cigarette butts poses environmental and aesthetic concerns due to improper disposal in public places, and existing solutions like pocket-ashtrays are considered inconvenient.
Innovation Solution
A flexible, metallized plastic bag with heat-resistant and isolating cardboard plates and plastic foil loops for extinguishing cigarettes, equipped with a re-sealable zip fastener and adhesive strip for secure closure, designed to be compact and attachable to a cigarette pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pocket-ashtray is carried for disposing cigarette butts, then cigarette butt disposal is enabled, but it is awkward and inconvenient
Solution Approach 1:
The butt bag is designed to be stored inside a cigarette pack, utilizing the existing space within the pack. The bag can be folded compactly and placed in the part-empty cigarette pack, saving space and eliminating the need for separate carrying of an ashtray device.
Solution Approach 2:
The butt bag is made from flexible plastic film that can be metallized with a thickness of 0.05 millimeter. This thin, flexible material allows the bag to be compact when empty and expand when containing butts, reducing bulk when carried while maintaining functionality.
2Reliability
If heat-resistant plates are added to extinguish cigarettes, then cigarette extinguishing function is achieved, but device complexity increases
Solution Approach 1:
The heat-resistant and isolating plates are integrated directly into the structure of the butt bag itself, rather than being separate components. The plates are attached to the inner surfaces of the bag's sides, combining the extinguishing function with the bag structure to minimize the number of separate parts.
Solution Approach 2:
The plates are made from composite materials - cardboard with an optional bonded layer of thin aluminium. This composite structure provides both heat resistance and insulation properties while keeping the plates thin and lightweight, reducing overall device complexity.
3Volume of moving object
If the bag is made from thin flexible plastic film, then the bag becomes compact and portable, but heat resistance for extinguishing cigarettes is reduced
Solution Approach 1:
The bag combines thin flexible plastic film (0.05mm metallized) for compactness with separate heat-resistant plates (0.3-1.5mm thick cardboard with optional aluminium layer) for thermal protection. The plastic film provides portability while the composite plates provide the necessary heat resistance.
Solution Approach 2:
Heat resistance is applied locally only where needed - on the inner surfaces of the bag's sides where the cigarette contacts the plates during extinguishing. The rest of the bag remains thin and flexible for compactness, optimizing both properties in their respective locations.

AI summary
Buttbag made of a flexible plastic film where the bottom edge is folded or welded to the bottom of the bag (3), both side edges (4) are welded together and the top edges (5), which can be opened, are fitted with a zipseal or adhesive, characterised by, that the both inner sides of the bag has close to the opening resisting /isolating plates (6), that on the outsides of the bag and outside the plates there are plastic loops (8) on the outside of the bag, in line with the plates, with the loops ends (9) fixed and the loops shaped to allow a thumb/finger to hook into each one such that the bag zipseal can be opened by spreading the thumb/finger; the finished cigarette can be extinguished by placing the glowing tip between the plates (6) and pressing them together with the thumb/finger.
