Cleanroom Apparel Layering for Worker Moisture Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clean rooms require low particle and humidity control, but human presence introduces moisture, necessitating high energy expenditure to maintain humidity levels, which is inefficient and costly.
Innovation Solution
A clothing system comprising outer and intermediate garments, where the intermediate garment has a conductive layer to wick away moisture and a storage layer to absorb it, allowing separate donning and doffing to manage moisture intake, with a moisture barrier preventing external release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ventilation and air conditioning are used to control humidity in clean rooms, then humidity control is improved, but energy consumption increases significantly
Solution Approach 1:
The invention extracts the moisture management function from the building's ventilation and air conditioning systems and relocates it to the personal clothing system worn by workers. The clothing system includes a moisture barrier layer to prevent moisture release and a storage layer to absorb moisture, thereby removing the need for high-energy HVAC systems to compensate for human-generated moisture.
Solution Approach 2:
The invention introduces an intermediary moisture management system between the worker's body and the clean room environment. The clothing system acts as this intermediary, with the storage layer absorbing moisture from the worker and the moisture barrier preventing its release into the clean room, thus mediating the interaction between human presence and environmental control requirements.
2Productivity
If people are present in clean rooms for work and inspections, then productivity is improved, but moisture introduction increases
Solution Approach 1:
The invention converts the harmful effect of human moisture generation into a beneficial feature by designing clothing that actively manages and stores this moisture. The storage layer in the clothing system absorbs moisture from the worker's body, transforming the moisture problem into a controlled storage function that prevents moisture release into the clean room while maintaining worker comfort and productivity.
3Reliability
If outer clothing is designed with moisture barrier, then moisture protection is improved, but comfort and breathability may deteriorate
Solution Approach 1:
The invention segments the clothing system into distinct functional layers: an inner layer for comfort and breathability, a middle storage layer for moisture absorption, and an outer moisture barrier layer for protection. This segmentation allows each layer to optimize its specific function without compromising the others, maintaining comfort while providing effective moisture protection.
Solution Approach 2:
The invention employs composite material structures in the clothing system, combining different materials with complementary properties. The storage layer uses moisture-absorbing materials while the outer barrier uses moisture-blocking materials, creating a composite system that simultaneously provides comfort, moisture management, and environmental protection.
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
Reduces moisture introduction into clean rooms, minimizing energy consumption by separating moisture within the clothing system and enabling efficient moisture management through layering and separation of garments.
Implementation Method 1
The intermediate garment has a conductive layer made of synthetic fibers. The conductive layer is designed to wick moisture away from the body.
Implementation Method 2
Between the moisture barrier and the conductive layer there is at least one storage layer made of a moisture-absorbing and moisture-storing material.
Implementation Method 3
The outer clothing is designed to be dustproof for clean rooms and also has a moisture barrier that blocks the escape of moisture from the inside to the outside.
