Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If decontamination systems are applied in the form of gel, spray or pulverization, then the decontaminating materials can reach the contaminated surfaces, but the dosage is not optimal and homogeneous, leading to overuse and inefficiency
Solution Approach 1:
The decontaminant is pre-applied to a support structure in a controlled manufacturing environment, creating a pre-dosed coating before deployment. This preliminary action ensures uniform distribution and eliminates the need for field application, thereby preventing overuse and ensuring optimal dosage on contaminated surfaces.
Solution Approach 2:
The patent replaces the mechanical application systems (spray guns, pulverization equipment) with a pre-formed coating system. The decontaminant is transferred from a liquid/spray state to a solid coating state on a support, eliminating the variability inherent in mechanical application methods and ensuring consistent, optimal dosing.
2Reliability
If decontamination systems are applied in the form of gel or spray, then the materials can be easily applied, but the reproducibility of the decontamination phase is poor
Solution Approach 1:
The decontaminant coating is prepared in advance under controlled conditions with precise dosing and uniform distribution. This preliminary preparation ensures that every application of the support delivers the exact same amount and distribution of decontaminant, guaranteeing reproducible results while maintaining ease of operation through simple deployment.
Solution Approach 2:
The patent changes the physical state and delivery parameters of the decontaminant from liquid/spray form to a solid coating on a support. This parameter change enables precise control over dosage, distribution, and application consistency, thereby improving reproducibility while maintaining operational simplicity through the ready-to-deploy nature of the coated support.
3Reliability
If more decontaminating materials are applied to ensure sufficient coverage, then the decontamination effectiveness may improve, but the efficiency decreases due to overuse
Solution Approach 1:
The patent optimizes the concentration and distribution parameters of the decontaminant in the coating formulation. By precisely controlling these parameters during manufacturing, the coating delivers the exact amount needed for effective decontamination without excess, thereby maintaining high effectiveness while improving efficiency through reduced material consumption.
Solution Approach 2:
The replacement of mechanical application systems with a pre-coated support eliminates the inefficiency of over-application. The controlled manufacturing process ensures that only the necessary amount of decontaminant is present on the support, delivering effective decontamination without the waste associated with mechanical spray or pulverization methods that require excess material to ensure coverage.
