Cigarette Bin Dual Baffle Smoke Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cigarette disposal bins fail to effectively extinguish fires and contain smoke, as they lack adequate mechanisms to restrict oxygen access and direct smoke upwards, leading to potential fire hazards and smoke escape.
Innovation Solution
The bin features a dual-baffle system where a first baffle guides waste into the container and a second baffle, extending upwards, directs smoke into an upper chamber, restricting oxygen access and containing smoke, while a magnetic container retention system and pivotable design facilitate easy emptying and fire prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional bins are used without adequate baffle structures, then the device complexity is reduced, but smoke escapes and fires are not effectively contained
Solution Approach 1:
The bin is divided into two distinct chambers: a lower chamber for waste containment and an upper chamber for smoke accumulation. This segmentation allows smoke to be directed upward into the upper chamber while keeping the lower chamber free of smoke, effectively containing harmful factors without requiring complex single-structure solutions.
Solution Approach 2:
The second baffle acts as an intermediary element between the aperture and the upper chamber. It redirects smoke flow from the aperture into the upper chamber, serving as a mediator that channels harmful smoke away from the waste containment area and into a dedicated smoke collection zone.
2Ease of operation
If the container is made removable for easy emptying, then the ease of operation is improved, but the reliability of fire containment may be compromised
Solution Approach 1:
The first baffle is designed to be pivotable between a first position (restricting the opening for normal operation) and a second position (enlarging the opening for emptying). This dynamic adjustment allows the same structure to provide both secure waste containment during normal use and easy access during emptying, maintaining both reliability and ease of operation.
Solution Approach 2:
The bin is divided into two distinct chambers: a lower chamber for waste containment and an upper chamber for smoke accumulation. This segmentation allows smoke to be directed upward into the upper chamber while keeping the lower chamber free of smoke, effectively containing harmful factors without requiring complex single-structure solutions.
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 dual-baffle system effectively extinguishes fires by limiting oxygen access and contains smoke within the bin, ensuring efficient waste retention and safe disposal, while the magnetic retention and pivotable design enhance usability and safety.
Implementation Method 1
The container, or at least a part thereof, may be manufactured from a magnetically attractive material and a magnet is present in the housing to attract the container and retain it in a predetermined location in relation to the housing.

AI summary
A bin for the disposal of cigarettes or the like, comprises an outer housing (10) defining a lower chamber (14) and an upper chamber (13). An inner container (17) in the lower chamber (14) of the housing (10) retains the discarded waste. The container (17) has an opening (19) for receipt of discarded waste and the housing (10) has at least one aperture (27) through which waste is discarded. The inner container (17) is disposed below the aperture (27). A first baffle (20) in the container (17) restricts the opening (19) in the container (17) and serves as a chute to direct discarded waste into the container interior. A second baffle (29) is positioned in the housing (10) above the container (17) and the first baffle (20), and between the opening (19) and the aperture (27). The second baffle (29) prevents any smoke that egresses from the opening (19) of the container (17) towards the aperture (27), guides said smoke toward the upper chamber (13) and restricts oxygen from entering the container to feed a fire. The container may be retained in place by a magnet (45).
