Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If cigarette butts are disposed of on the ground, then immediate disposal is achieved, but environmental pollution and health risks increase
Solution Approach 1:
The invention divides the disposal process into two stages: immediate containment in a portable bag, and later disposal in a refuse bin. The bag segments the harmful cigarette butt from the environment during transport, while the refuse bin provides final containment, thus resolving the contradiction between immediate disposal and environmental protection.
Solution Approach 2:
The portable cigarette butt receiving bag acts as an intermediary device between the cigarette butt and the final disposal location. It provides temporary containment and transport capability, allowing the harmful substance to be moved away from the immediate environment without direct ground disposal, thereby reducing environmental pollution while maintaining disposal efficiency.
2Ease of operation
If cigarette butts are accessible in open disposal, then ease of disposal is achieved, but accessibility to children and animals increases
Solution Approach 1:
The invention uses a flexible bag with a closure flap made of thin film material that can be easily opened and sealed. The closure flap, when sealed with pressure-sensitive adhesive, creates an effective barrier that prevents children and animals from accessing the cigarette butts inside, while still allowing easy access for the adult user during disposal.
Solution Approach 2:
The portable receiving bag is designed as a disposable item that is inexpensive and single-use. This allows it to be readily available and easily discarded after use, maintaining ease of operation while providing effective protection during the critical transport period when children and animals might access the contents.
3Ease of operation
If ambient air is present around cigarette butt, then easy introduction into bag is achieved, but fire safety decreases
Solution Approach 1:
The invention creates an oxygen-deprived environment inside the bag by minimizing ambient air presence around the cigarette butt. The closure flap seals the bag to exclude external air, and the narrow space between the butt and bag walls further limits oxygen availability, thereby extinguishing the glowing butt and eliminating fire hazard while still allowing easy introduction.
Solution Approach 2:
The flexible bag material and closure flap design allow for easy opening and introduction of the cigarette butt, then seamlessly seal to create the oxygen-deprived environment. The flexibility of the thin film enables simple one-handed operation for introduction while effectively excluding air to prevent fire.
4Reliability
If closure flap with pressure-sensitive adhesive is used, then sealing effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The closure flap with pressure-sensitive adhesive is designed for single-use in an inexpensive disposable bag. The simple adhesive sealing mechanism is cost-effective for single-use applications and provides reliable sealing without requiring complex manufacturing processes, making it suitable for mass-produced disposable products.
Solution Approach 2:
The pressure-sensitive adhesive changes its bonding parameters based on applied pressure and time. During sealing, pressure activates the adhesive to bond the closure flap to the bag, creating an effective seal. This simple parameter-based mechanism achieves reliable sealing without complex manufacturing, suitable for disposable products.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents environmental pollution, protects children and animals from hazardous materials, ensures fire safety by extinguishing glowing butts, and provides a cost-effective means for handling large numbers of disposed cigarette butts.
Implementation Method 1
a pressure sensitive adhesive is arranged along the entire width of the flap to ensure tight sealing of the bag
Implementation Method 2
The heat insulator consists of a heat insulating material, such as a polymer absorbent in a porous material
Implementation Method 3
the width of the forward inner layer material and the width of the rearward inner layer material between two longitudinal edges of the respective forward and rearward inner layer material together substantially correspond to a circumference of the cigarette butt. This will increase safety to fire due to disposed glowing cigarette butts, since the ambient air around the cigarette butt in the butt receiving compartment of the disposable cigarette butt receiving bag is minimized

AI summary
The invention relates to a cigarette butt receiving bag of disposable type for receiving and extinguishing glowing cigarettes, which bag (1) comprises a forward sheet (2), a rearward sheet (4), which sheets are sealed to each other along their outer edges (6) leaving an edge portion unsealed so as to provide an opening (8) for receiving a cigarette butt (10), thereby forming a cigarette butt receiving compartment (12) between said forward and rearward sheets (2, 4), and comprising a fluid (14), which is disposed in two heat insulating volumes (16, 18) within the cigarette butt receiving compartment (12). A first heat insulating volume (16) is delimited by the forward sheet (2) and a forward inner layer material(20) which is sealed against the forward sheet (2). A second heat insulating volume (18) is delimited by the rearward sheet (4) and a rearward inner layer material (22) which is sealed against the rearward sheet (4). The invention also relates to a method of manufacturing a cigarette butt receiving bag of disposable type.
