Window-Mounted Smoking Hood With Exhaust Venting for Indoor Smoke Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smokers face inconvenience when trying to smoke indoors due to indoor smoke pollution, especially in weather conditions that make outdoor smoking undesirable, and there is a need to minimize smoke pollution in enclosed spaces like offices and apartments.
Innovation Solution
An indoor smoking hood system is designed to be attached to a sash window frame, comprising tubular frames with adjustment locks and clamps, a pivotable and slidable hood frame, and an exhaust fan to direct smoke outdoors through a clear plastic enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smokers smoke indoors, then convenience is improved, but indoor smoke pollution increases
Solution Approach 1:
The patent extracts the smoke exhaust function from the indoor environment by installing an exhaust fan that actively removes smoke from the enclosure and discharges it outdoors through a duct, separating the harmful smoke from the indoor air space while maintaining the convenience of indoor smoking
Solution Approach 2:
The patent introduces a clear plastic enclosure as an intermediary structure between the smoker and the indoor environment, containing the smoke within a defined space and providing a controlled atmosphere that prevents smoke dispersion into the broader indoor area
2Object-generated harmful factors
If outdoor smoking is required to reduce indoor pollution, then indoor air quality is improved, but convenience deteriorates due to weather conditions
Solution Approach 1:
The patent enables the smoking area to serve itself by creating a self-contained enclosure with integrated exhaust ventilation that automatically manages smoke removal, eliminating the need for smokers to relocate outdoors while maintaining effective smoke control
3Stability of the object's composition
If a fixed smoking hood structure is used, then structural stability is improved, but adaptability to different window widths deteriorates
Solution Approach 1:
The patent divides the hood structure into modular tubular frame sections that can be individually adjusted and reconfigured, allowing the overall structure to adapt to different window widths while maintaining structural integrity through standardized connection mechanisms
Solution Approach 2:
The patent incorporates adjustable and movable components into the hood structure, including telescopic arms and repositionable clamps, that enable the fixed structure to dynamically adapt to varying window dimensions while maintaining stable attachment and structural rigidity
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 system effectively captures and exhausts smoke outdoors, reducing indoor pollution while allowing smokers to smoke comfortably indoors, even in adverse weather conditions, by utilizing a clear plastic enclosure and exhaust fan to manage smoke ventilation.
Implementation Method 1
An exhaust fan is installed on the fan plate to air in the hood to outdoor

AI summary
The present invention features an indoor smoking hood system disposed on a sash window frame. The hood comprises a first side tubular frame and a second tubular frame. The frames are joined together by adjustment locks for the attachment of variable window width. The frames are attached to the window frame via a plurality of window clamps. A hood frame is slidably and pivotably attached to the first side tubular frame and second tubular frame. A clear plastic hood provides enclosure of the hood for a smoking area. A fan plate is attached to the top of the tubular frame with a plurality of fan plate clips. An exhaust fan is installed on the fan plate to air in the hood to outdoor.
