Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarette use generates respiratory emissions with odors and harmful chemicals that are exhaled into the environment, posing a nuisance and health risk to others.
Innovation Solution
An apparatus with a housing, mouthpiece, filter cavity, and a filter configured to receive and filter respiratory emissions, utilizing a positive pressure gradient to transmit emissions through a filter media for purification before exhalation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter is added to the electronic cigarette apparatus, then the purity of exhaled emissions is improved, but the device complexity increases
Solution Approach 1:
The filter is nested within the existing electronic cigarette apparatus housing, utilizing the filter cavity and integrating with the flange structure. This allows the filtering function to be added without requiring a completely separate external device, thereby reducing the overall complexity increase while achieving emission purification.
Solution Approach 2:
The filter acts as an intermediary component between the user's respiratory emissions and the external environment. It mediates the passage of exhaled air, particulates, and chemicals through its filtering medium, allowing beneficial gases to pass while blocking harmful substances, thus resolving the contradiction between maintaining device simplicity and achieving effective filtration.
2Object-affected harmful factors
If the filter cavity is designed with a pocket and frame structure, then the filtration effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
The filter assembly is segmented into distinct functional components: the filter media, the pocket structure, and the frame. This segmentation allows each component to be manufactured separately using optimized processes and then assembled together, reducing overall manufacturing complexity while maintaining effective filtration performance.
Solution Approach 2:
The filter pocket is designed as a flexible structure that can be formed from thin materials, allowing for easy manufacturing and assembly. The flexible nature of the pocket enables it to conform to the filter media and seal effectively without requiring complex rigid structures, thereby simplifying the manufacturing process while maintaining filtration effectiveness.
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 apparatus effectively reduces the amount of particulates and chemicals in exhaled emissions, minimizing their transmission to others and improving air quality around the user.
Implementation Method 1
The filter is spaced from body within the filter cavity to facilitate transmission through the filter by a positive pressure gradient within the pocket

AI summary
An apparatus for filtering respiratory emissions includes a housing. The housing includes a mouthpiece defining a port, a body at least partially defining a filter cavity, and a flange at least partially defining a passageway in fluid communication with the port and extending into the filter cavity. The apparatus includes a filter disposed within the filter cavity and fluidly coupled to the port via the flange. The filter is configured to receive respiratory emissions from the port and emit from the filter as filtered respiratory emissions.
