Portable Smoke Purifier Filtration for Source Capture and Ash Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers are inadequate in eliminating secondhand smoke pollution from indoor spaces, as they rely on continuous air circulation and fail to prevent smoke from dispersing into the air, posing a health risk to non-smokers.
Innovation Solution
A portable smoke purifier with a purifying portion, grip portion, and mouthpiece assembly that includes a filter cartridge, fan, and a detachable metal mesh to capture and filter smoke directly at the source, preventing its dispersion and collecting ash to reduce fire hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable smoke purifier is designed to directly capture and filter smoke at the source, then the smoke purification effectiveness is improved, but the device complexity increases
Solution Approach 1:
The smoke purifier is divided into three main segments: purifying portion, grip portion, and mouthpiece. Each segment has specific functions - the purifying portion contains the filter cartridge for smoke filtration, the grip portion houses the fan and battery, and the mouthpiece connects to the cigarette filter tip. This segmentation allows each component to be optimized independently while working together to achieve effective smoke purification.
Solution Approach 2:
The filter cartridge is nested within the metal mesh, which is inserted into the purifying portion cavity. The cigarette mesh is placed within the sleeve frame, and the entire assembly is structured concentrically. This nested arrangement maximizes space utilization and ensures that smoke passes through multiple filtration stages (cigarette mesh → metal mesh → filter cartridge) in sequence, enhancing purification effectiveness without proportionally increasing overall device size.
2Ease of operation
If the device is designed to be portable and attach to cigarette filter tips, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The mouthpiece is designed with a universal connection interface that attaches to standard cigarette filter tips. The connecting port with threading allows the mouthpiece to be universally compatible with various cigarette types. This universal design simplifies operation for users while requiring precise manufacturing of the threading and connection dimensions to ensure reliable attachment across different cigarette brands.
Solution Approach 2:
The device transitions from a static air purifier to a dynamic portable system that moves with the user. The mouthpiece can be detached and reattached to the cigarette filter tip, and the grip portion can be removed from the purifying portion. This dynamic design enhances ease of operation by allowing the device to be attached to any cigarette, while requiring precise manufacturing tolerances for the detachable connections to ensure proper assembly and disassembly.
3Productivity
If the fan is positioned to blow air towards air outlets in the grip portion, then the smoke capture efficiency is improved, but the energy consumption increases
Solution Approach 1:
The fan is positioned to create a pre-suction effect that draws smoke toward the filter cartridge before the smoke can disperse into the surrounding environment. The air outlets in the grip portion are positioned to direct airflow toward the smoke source (cigarette), creating a controlled flow path that captures smoke at the point of generation. This preliminary action increases smoke capture efficiency while minimizing the energy required compared to attempting to capture smoke after it has dispersed throughout the room.
Solution Approach 2:
The device uses pneumatic principles to create controlled airflow through the filter cartridge. The fan generates pressure differential that moves smoke through the porous filter material. The air outlets are designed to optimize airflow patterns, creating a focused pneumatic flow that efficiently captures and transports smoke to the filter without requiring excessive fan power. This pneumatic optimization balances smoke capture efficiency with energy consumption.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively purifies both exhaled and combusted smoke, minimizing secondhand smoke exposure and preventing ash from falling outside, thus reducing air pollution and fire risks.
Implementation Method 1
A filter cartridge for filtering smoke is arranged in the metal mesh
Implementation Method 2
The fan blows air towards the air outlets in the grip portion
Implementation Method 3
a magnet is arranged at the bottom of the sleeve frame, the cigarette mesh is made from metal capable of being attracted by the magnet, and when the cigarette mesh is placed in the sleeve frame, the magnet comes into contact with the cigarette mesh and attracts and fixes the cigarette mesh
