Cleanroom arrangement and method for rapidly providing a cleanroom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleanroom technologies are complex and costly, and they struggle to provide quickly available, dry, and particle-free environments, especially in applications like battery production and satellite technology, where atmospheric humidity is particularly disadvantageous.
Innovation Solution
A cleanroom arrangement with two shell walls, one diffusion-proof to moisture and the other air-permeable, creates a dry atmosphere by drying ambient air in a separate space and filtering it to produce ultra-pure air, using a mobile fan-filter unit and air drying unit to maintain a pressure gradient that prevents contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cleanroom technologies are used, then particle-free environment is achieved, but setup time is long and cost is high
Solution Approach 1:
The cleanroom system is divided into two independent shell walls: an outer shell wall for moisture control and an inner shell wall for particle filtration. This segmentation allows each component to be optimized independently and assembled quickly, reducing overall setup time while maintaining both dryness and particle-free conditions
Solution Approach 2:
The outer shell wall is set up first to create a controlled environment, followed by the inner shell wall. This preliminary action of establishing the outer barrier before the inner one enables rapid sequential assembly while ensuring both environmental requirements are met
2Manufacturing precision
If conventional cleanroom technologies are used, then particle-free environment is achieved, but cost is high
Solution Approach 1:
By separating the moisture control function (outer shell) from the particle filtration function (inner shell), the system uses simpler, less expensive materials for each component rather than requiring expensive multi-functional materials, reducing overall manufacturing cost
Solution Approach 2:
The use of flexible shell walls instead of rigid conventional cleanroom structures reduces material costs and simplifies assembly, making the particle-free environment more cost-effective to achieve
3Device complexity
If single shell wall design is used, then setup is simpler, but ability to control both humidity and particles is insufficient
Solution Approach 1:
The dual shell wall design segments the environmental control functions: the outer shell handles moisture control while the inner shell handles particle filtration. This functional segmentation achieves superior environmental control without requiring each shell to perform multiple complex functions
Solution Approach 2:
The outer shell wall acts as an intermediary that pre-dries the ambient air before it reaches the inner shell wall and cleanroom space, reducing the load on the particle filtration system and enabling both humidity and particle control to work together more effectively
4Loss of time
If ambient air is used directly, then setup is quick, but humidity control is insufficient
Solution Approach 1:
The outer shell wall performs preliminary drying of ambient air before it enters the inner cleanroom space. This preliminary action of moisture removal occurs automatically as air passes through the outer shell, enabling quick setup without complex drying systems while still achieving precise humidity control
Solution Approach 2:
The outer shell wall serves as an intermediary barrier that selectively controls moisture transfer from ambient air to the cleanroom environment, allowing rapid deployment while maintaining precise humidity control through its diffusion-proof properties

Implementation Method 1
a first shell wall arrangement (1), which separates a first space (R1) that is indirectly or directly adjacent to a floor area (4), having a flexibly foldable shell wall (9) directly facing the first space (R1), which is made exclusively of at least one air-permeable material suitable for cleanrooms
Implementation Method 2
a second shell wall arrangement (2), which encloses the first shell wall arrangement (1) together with a second space (R2) that surrounds the first shell wall arrangement (1) and the mobile filter-fan unit (FVE) arranged therein with a flexibly foldable shell wall (3), which is made exclusively from at least one material that is diffusion-proof against moisture
Implementation Method 3
a mobile filter-fan unit (FVE), which has an air inlet area (10) and an air outlet area (11) arranged outside the first space (R1) and serves to generate pure or ultra-pure air from ambient air
