Extendible Containment Booth for Sterile Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile and modular clean rooms or containment booths are limited in length and unable to maintain complete containment of spaces with negative air flow, and they lack the ability to be connected to wall surfaces, restricting their use with longer materials and effective isolation in sterile environments.
Innovation Solution
A containment booth assembly with extendible vertical sidewalls and sliding panels that can interface with ceilings and walls, featuring a fan system for negative pressure and filtration to prevent contaminant escape, allowing for adjustable and expanded workspaces while maintaining isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete containment with negative air flow is maintained, then contaminant isolation is improved, but the booth length is limited and cannot accommodate longer materials
Solution Approach 1:
The containment system is divided into multiple modular booth units that can be connected end-to-end. Each module maintains its own containment integrity with sealed joints, allowing the system to extend in length while preserving negative pressure containment across the entire assembled structure.
Solution Approach 2:
The booth modules are designed to connect and nest together, with each module containing its own containment environment. The nested connection design allows multiple containment zones to be joined while maintaining the overall negative pressure field and contaminant isolation across the extended length.
2Ease of manufacture
If fixed booth dimensions are used, then manufacturing simplicity is improved, but adaptability to different workspace requirements is reduced
Solution Approach 1:
The booth incorporates movable walls and adjustable panel systems that can be reconfigured between different operational states. The walls can extend or retract, and panels can be repositioned to create different workspace configurations while maintaining containment integrity, allowing the same manufactured unit to adapt to various spatial requirements.
Solution Approach 2:
The booth is designed as a universal platform that can serve multiple functions and configurations. The standardized modular design with adjustable components allows a single manufactured unit to adapt to different workspace sizes, shapes, and operational requirements, eliminating the need for custom manufacturing for each application.
3Adaptability or versatility
If wall connection capability is added, then adaptability to room surfaces is improved, but device complexity increases
Solution Approach 1:
The booth incorporates flexible sealing interfaces and compliant gasket systems that can conform to various wall surface geometries. These flexible sealing elements allow the rigid booth structure to adapt to irregular or non-planar wall surfaces without requiring complex custom fabrication, maintaining containment while simplifying the overall design.
4Volume of moving object
If extendible walls and ceiling interface are implemented, then workspace volume is increased, but structural complexity increases
Solution Approach 1:
The booth employs dynamic, motorized or mechanically-assisted wall extension mechanisms that can smoothly transition between retracted and extended states. The ceiling interface system uses telescoping or articulating components that maintain structural integrity while enabling volume adjustment, allowing the containment space to be dynamically resized without requiring multiple complex fixed-structure configurations.

AI summary
A containment booth assembly includes a floor, a plurality of vertical sidewalls, and a plurality of sliding panels corresponding to each of the vertical sidewalls. The plurality of sliding panels define an extendible top portion, the extendible top portion extendible upwardly and configured to interface with a ceiling surface of a room above the containment booth assembly. In a non-limiting aspect or embodiment, one or more of the plurality of vertical sidewalls is rotatably mounted to vertical support beams and define an extendible side portion. The extendible side portion is extendible horizontally and configured to interface with a wall surface of the room beside the containment booth assembly.
