Relocatable Corrosion Control Facility Zone Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facilities lack a relocatable and effective solution for managing hazardous particulates during aircraft and vehicle corrosion control processes, leading to potential cross-contamination and safety hazards due to inadequate separation of zones and handling of hazardous materials.
Innovation Solution
A relocatable corrosion control facility with three separated zones (red, yellow, and green) that includes multiple air showers, specific storage enclosures, and independent air conditioning systems to minimize contamination, featuring a work area for de-painting and re-painting, an undressing area with multiple air showers, and a staging area for clean operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single integrated facility is used for de-painting, corrosion removal and re-painting, then all operations can be performed in one location, but cross-contamination of hazardous particulates occurs between different operational zones
Solution Approach 1:
The facility is divided into three distinct zones (red, yellow, green) with separate air handling systems and controlled access points. Each zone handles specific operations (de-painting, corrosion removal, re-painting) and maintains independent atmospheric control to prevent cross-contamination of hazardous particulates between zones.
Solution Approach 2:
Air showers are installed at transitions between zones to act as intermediary barriers. These air showers create controlled air curtains that prevent the movement of hazardous particulates from contaminated zones to cleaner zones, enabling integrated operations while maintaining separation.
2Reliability
If a fixed permanent facility is constructed for corrosion control, then structural stability and safety are improved, but relocatability and assembly speed deteriorate
Solution Approach 1:
The facility employs a modular construction system with interlocking panels and components that can be rapidly assembled and disassembled. This dynamic design allows the structure to transition between deployed and stored states while maintaining structural integrity during operation, enabling both reliability and relocatability.
Solution Approach 2:
The facility utilizes lightweight yet structurally sound panel systems that provide the necessary structural stability when assembled but can be easily broken down and relocated. The modular panels maintain rigidity and safety during use while allowing for rapid deployment and reconfiguration.
3Object-affected harmful factors
If multiple air showers are installed between zones, then cross-contamination is reduced, but device complexity and space requirements increase
Solution Approach 1:
Air showers are positioned at vertical transitions (stairs) between zones rather than only at horizontal doorways. This three-dimensional placement optimizes the use of space and provides effective particulate control at critical transition points without requiring excessive numbers of air showers throughout the facility.
Solution Approach 2:
The air showers are integrated into the facility's existing air handling system and structural framework, utilizing the same airflow generation and filtration components throughout. This self-consistent design reduces overall system complexity while maintaining effective cross-contamination prevention.
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
The facility effectively reduces cross-contamination risks by providing a structured and safe environment for handling hazardous materials, ensuring worker safety and facility integrity through rigorous particulate management and separation of zones.
Implementation Method 1
The second air shower preferably blows air at different angles to remove additional particles
Implementation Method 2
The technician enters the first air shower from the stairs and is vacuumed by the first air shower for some period of time
Implementation Method 3
The red zone, yellow zone and green zone preferably include independent air conditioning systems, to further prevent contamination

AI summary
A relocatable corrosion control facility preferably includes a red zone, a yellow zone and a green zone. The red zone is a work area. The work area preferably includes at least one combination paint and sanding booth, an eye wash, a compressor, an air tank, a storage enclosure and a hazardous storage. The yellow zone is an undressing area. The undressing area preferably includes at least two air showers; a respirator and personal protective equipment locker room (RPPE); and at least one dirty locker room. The technician removes equipment in the RPPE locker room and exits into a dirty locker room. The dirty locker room includes dirty clothes storage, showers and sinks. An exit of each dirty locker room leads into a green zone. The green zone is a staging area. The staging area includes at least one clean locker room, at least one office and a lobby.
