Smoke Generator With Sector Deflector for Even Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smoke generators often distribute smoke unevenly in a room, providing areas of less dense smoke that allow intruders to continue unauthorized activities despite the alarm, and there is a need for a compact, easily manufactured, and easily replaceable smoke generator and deflector system.
Innovation Solution
A smoke generator with a smoke deflector designed to evenly distribute smoke using a cylindrical sector-shaped cavity with an inlet and outlet opening, featuring a residual collector for debris and a two-piece canister housing for easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If smoke is generated without a deflector, then the smoke generator structure is simple, but the smoke distributes unevenly in the room creating areas of less dense smoke
Solution Approach 1:
The smoke generator is divided into separate functional components: a smoke canister for smoke generation, a deflector assembly for smoke distribution, and a housing for structural support. This segmentation allows each component to be optimized independently for its specific function while maintaining overall system simplicity
Solution Approach 2:
The deflector assembly acts as an intermediary component between the smoke canister and the room environment. It receives smoke from the canister and redistributes it uniformly throughout the room, solving the uneven distribution problem without requiring complex internal canister modifications
2Volume of moving object
If a compact smoke generator is designed, then the device size is reduced, but the ease of replacement for expendables becomes difficult
Solution Approach 1:
The smoke generator employs a modular design where the smoke canister, battery, and deflector assembly are distinct replaceable units. This allows users to replace only the expendable components (canister and battery) without replacing the entire device, maintaining compactness while enabling easy maintenance
Solution Approach 2:
The housing incorporates removable panels or access points that allow dynamic access to internal components. This enables users to replace expendables like the smoke canister and battery without disassembling the entire compact unit, balancing size constraints with maintenance accessibility
3Reliability
If a smoke deflector with residual collector is used, then debris collection is improved, but the device complexity increases
Solution Approach 1:
The residual collector is merged with the deflector assembly, combining two functions (smoke distribution and debris collection) into a single integrated component. This eliminates the need for separate debris collection mechanisms, maintaining reliability while controlling complexity
Solution Approach 2:
The deflector assembly's structure naturally guides debris toward the residual collector during smoke deployment. The design uses the smoke flow dynamics itself to perform the collection function, reducing the need for additional active components or complex mechanical systems
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 smoke generator effectively distributes smoke evenly, subdues intruders by impairing their vision and breathing, and allows for easy maintenance and replacement of components without tools.
Implementation Method 1
a break-in or other similar unauthorised access to a room or building is taking place in order to subdue the amount of harm caused by the intruder by impairing his or her vision and maybe also his or her breathing
Implementation Method 2
The smoke deflector cavity has an inlet opening as described above, and an elongated outlet opening, horizontally arranged, for distributing the smoke into the room

AI summary
A smoke generator for anti-burglar purposes includes a canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further includes a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape. The smoke generator is provided with a cartridge for the canister to ease replacement of used or expired canister. The smoke deflector is provided with a residual collector to prevent residuals and debris from littering the room where the smoke generator is used.
