Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air conditioners and central air systems are ineffective in filtering PM2.5 particles, allowing them to enter indoor spaces and pose health risks due to poor air circulation and limited filtration capabilities, which fail to capture smaller particles.
Innovation Solution
An air cleaning machine comprising a hollow tube body with an adsorbent material, a detect chip, and air outlet assemblies that circulate air through a system of holes and fans to absorb and remove PM2.5 particles, with a design allowing for easy replacement of the adsorbent material and monitoring of particle concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional air conditioners and central air systems are used, then air circulation is provided, but PM2.5 particles cannot be effectively filtered and enter indoor spaces
Solution Approach 1:
The device segments the air filtration process into multiple stages: initial air intake through the hollow tube body, detection of PM2.5 concentration by the detect chip, active pumping by the fan when pollution is detected, and final filtration through the adsorbent material. This segmented approach ensures both PM10 and PM2.5 particles are effectively captured.
Solution Approach 2:
The adsorbent material serves as an intermediary substance that actively captures and retains PM2.5 particles. The detect chip acts as an intermediary sensor that monitors air quality and triggers the fan activation. These intermediary elements bridge the gap between air intake and clean air output.
2Productivity
If air circulation is poor, then suspended particles accumulate, but traditional systems fail to remove them effectively
Solution Approach 1:
The system dynamically adjusts its operation based on real-time air quality conditions. The detect chip continuously monitors PM2.5 concentration, and the fan is activated only when pollution levels exceed thresholds. This dynamic response optimizes air purification efficiency while energy is needed.
Solution Approach 2:
The detect chip provides feedback on air quality conditions to the control system. When PM2.5 concentration exceeds acceptable levels, the system receives feedback to activate the fan and increase filtration. This closed-loop feedback mechanism ensures sustained air purification efficiency.
3Object-affected harmful factors
If adsorbent material is used to capture PM2.5, then air purification is improved, but maintenance and replacement become complex
Solution Approach 1:
The device segments the adsorbent material into a removable module housed within the hollow tube body. This modular design allows users to access and replace the adsorbent material without disassembling the entire device, significantly improving ease of maintenance while maintaining effective PM2.5 removal capability.
4Object-affected harmful factors
If detection and active pumping are added, then PM2.5 removal is enhanced, but device complexity increases
Solution Approach 1:
The device merges multiple functions into a compact integrated structure: the hollow tube body houses both the detect chip and adsorbent material, the fan is positioned to work directly with the tube body, and the control system integrates detection and pumping operations. This merging reduces overall device complexity while enhancing PM2.5 removal capability.
Solution Approach 2:
The hollow tube body serves multiple functions: it acts as the structural housing, the air intake channel, and the container for both the detect chip and adsorbent material. The fan serves dual purposes of air intake and forcing air through the filtration medium. This multi-functionality reduces the number of separate components needed.

AI summary
Disclosed is an air cleaning machine, which mainly comprises a hollow tube body, a detect chip, an adsorbent material, a large shell body and two air outlet assemblies, the air circulation is formed through a plurality of holes disposed on an underside of the large shell body and a round hole disposed on the side of the large shell body, so the air is able to flow through via an air hole disposed on the one side of the fixing sheet of the hollow tube body. Thus, the detect chip arranged closely to the air hole of the fixing sheet on one side of the hollow tube body can detect the concentration of the suspended particles (PM2.5) in the air.
