Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In hospital settings, traditional methods for maintaining negative air pressure during small repairs or upgrades are costly and inefficient, as they often require large spaces to be rendered unusable for extended periods, posing risks to patients and staff from airborne contaminants.
Innovation Solution
A portable, negative air pressure box with a vacuum system that allows for controlled internal pressure lower than the surrounding environment, equipped with a transparent lid, adjustable legs, and HEPA filtration, enabling safe containment of contaminants during repairs without disrupting the room's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional negative pressure methods are used for repairs, then airborne contaminants are contained, but large spaces must be rendered unusable for extended periods
Solution Approach 1:
The invention divides the containment space into a small, localized box rather than enclosing the entire room. This segmentation allows repairs to be performed in a confined area while the rest of the hospital room remains accessible and functional, resolving the contradiction between effective contaminant containment and room usability.
2Reliability
If traditional negative pressure methods are used for repairs, then airborne contaminants are contained, but maintenance costs increase
Solution Approach 1:
The invention extracts the negative pressure containment system from the entire room scale and condenses it into a portable box. This extraction reduces the volume of space requiring pressurization control, lowering energy consumption and maintenance costs while preserving the essential contaminant containment function.
3Volume of moving object
If portable box is used for repairs, then space occupation is minimized, but device complexity increases
Solution Approach 1:
The portable box incorporates HEPA filtration and vacuum systems as intermediary components to achieve negative pressure containment in a compact form. These intermediary systems enable the box to maintain complex containment functions within a minimized volume, resolving the contradiction between small size and functional complexity.

AI summary
The disclosed apparatus make possible the maintenance, repair, alteration, and upgrade of walls and wall mounted facilitates within hospitals and cleanrooms while occupying a minimum area. In one embodiment the apparatus is a six-sided box with an open side, a transparent side, and a side with two hand ports. To operate, the apparatus is placed, from the open side, against the wall or the wall facility that needs repair or upgrade. Afterwards the air inside the apparatus is vacuumed to lower the air pressure with respect to the surrounding pressure before the hands of a repairman enters the apparatus through the two hand ports. Repair can start at this time while the apparatus maintains a negative inside air pressure and while no particles of contaminants can escape the apparatus. The vacuumed air may be released back into the room or hallway after it is filtered.
