Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If existing VHP decontamination systems are designed with integrated components, then the system structure is simplified, but the weight increases making components difficult to transport

Engineering Contradiction:
Improvesystem structureVSAvoidcomponent weight
Core Design Contradiction:
Device complexityVSWeight of moving object

Solution Approach 1:

The decontamination system is divided into separate modular components including a decontamination unit, a dryer unit, and a destroyer unit that can be transported independently and assembled at the destination. This segmentation reduces the weight of individual transportable components while maintaining system functionality.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If existing VHP systems use fixed capacity components, then the device complexity is reduced, but the adaptability to decontaminate enclosures of various dimensions is insufficient

Engineering Contradiction:
Improvecomponent configurationVSAvoidenclosure size adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system incorporates adjustable flow rate controls and variable capacity components that can be dynamically configured to match different enclosure sizes. The dryer and destroyer units can adjust their operational capacity to accommodate various decontamination requirements.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If existing VHP systems lack additional destroyer capacity, then the device complexity is minimized, but the aeration efficiency is insufficient for large enclosures

Engineering Contradiction:
Improvecomponent configurationVSAvoidaeration efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system merges the dryer unit and destroyer unit into a coordinated assembly that works together to enhance aeration efficiency. The destroyer unit provides additional capacity to break down vaporized hydrogen peroxide, while the dryer removes moisture, collectively improving the aeration process for large enclosures.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A decontamination system having modular components to efficiently decontaminate enclosures of various dimensions. The decontamination system can carry out a method for establishing a first concentration level of the vaporized decontaminant and determining a first exposure time associated with the first concentration level; injecting the vaporized decontaminant into the region (6) at an injection rate for obtaining the first concentration level of the vaporized decontaminant in the region (6); monitoring the actual concentration (CACTUAL) of the vaporized decontaminant in the region (6); determining the dew point concentration (CDP) of the vaporized decontaminant in the region (6); determining whether the actual concentration (CACTUAL) of the vaporized decontaminant in the region (6) is at least a predetermined amount below the dew point concentration (CDP) of the vaporized decontaminant in the region (6); and decreasing the injection rate if the actual concentration (CACTUAL) of the vaporized decontaminant in the region is not at least the predetermined amount below the dew point concentration (CDP) of the vaporized decontaminant in the region (6).
