Clean room module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clean room modules with air inlet and outlet circulation systems experience rapid filter degradation and prolonged time to achieve preset cleanliness due to continuous introduction of external dirty air, necessitating frequent filter replacement and extended cleaning times.
Innovation Solution
A clean room module design where the gas circulation device is sealed to prevent external gas exchange, with a filter integrated within the system to recirculate and filter air internally, reducing filter degradation and shortening the time to reach cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circulation system with air inlet and air outlet is provided to ensure cleanliness, then the clean room module can maintain air quality, but the filter degradation is relatively large and the time required to achieve preset cleanliness is prolonged
Solution Approach 1:
The patent creates a closed circulation system where air is continuously recirculated and filtered within the clean room module without continuous introduction of external dirty air. This closed environment protects the filter from rapid degradation by limiting its exposure to contaminant-laden external air, thereby extending filter service life while maintaining cleanliness through repeated filtration cycles of the enclosed air
2Productivity
If external air is continuously introduced through air inlet to maintain circulation, then the circulation system can operate continuously, but the time required to achieve preset cleanliness is prolonged
Solution Approach 1:
The patent implements a closed circulation system where air is continuously recirculated through the filter and returned to the clean room module. This continuous circulation of the same air volume allows the system to quickly achieve preset cleanliness by repeatedly filtering the enclosed air, rather than continuously introducing new external air that requires filtration from scratch. The continuous useful action of recirculating and re-filtering the same air accelerates the attainment of cleanliness standards
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
Significantly reduces the time required to achieve preset cleanliness and prolongs the service life of consumables by maintaining a closed gas circulation system, minimizing filter degradation and enhancing operational efficiency.
Implementation Method 1
a filter arranged in the gas circulation device, wherein the gas in the accommodation cavity is drawn out from the air outlet through the gas circulation device, filtered by the filter

AI summary
The present invention relates to a clean room module, which includes: a housing defining an accommodation cavity therein and formed with an air inlet and an air outlet; a gas circulation device arranged at the housing, with two ends thereof being connected to the air inlet and the air outlet respectively, the housing and the gas circulation device being both sealed to define a confined space without gas exchange with outside; and a filter arranged in the gas circulation device, wherein the gas in the accommodation cavity is drawn out from the air outlet through the gas circulation device, filtered by the filter, and sent back to the accommodation cavity from the air inlet. The clean room module of the present application can significantly reduce the time required for the accommodation cavity to reach a preset cleanliness after the cleaning function is activated.
