Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bioscrubbers are used for decontamination, then decontamination capability is provided, but stability issues arise
Solution Approach 1:
The patent changes the chemical parameters by replacing protein-based bioscrubbers with cyclodextrin-based chemical scavengers. This parameter change maintains decontamination capability while improving stability, as cyclodextrins are chemically stable macrocyclic compounds that do not suffer from the stability issues affecting bioscrubbers.
2Reliability
If bioscrubbers are used for decontamination, then decontamination function is achieved, but immunogenicity risks increase
Solution Approach 1:
The patent employs disposable cyclodextrin-based chemical scavengers that eliminate immunogenicity risks associated with bioscrubbers. These chemical scavengers can be used once and then discarded, avoiding any potential immunogenic reactions while maintaining effective decontamination function.
3Reliability
If proteins are immobilized on textile support, then decontamination device is created, but immobilization difficulty increases
Solution Approach 1:
The patent changes the material parameters by replacing proteins with cyclodextrin-based chemical scavengers. This parameter change simplifies immobilization on textile supports, as cyclodextrins can be more easily attached to textiles compared to proteins, thereby improving ease of manufacture while maintaining decontamination device functionality.
4Loss of time
If decontamination devices are made ready-to-use, then response time is improved, but device complexity increases
Solution Approach 1:
The patent employs self-service cyclodextrin-based chemical scavengers that are ready-to-use without requiring complex activation or preparation procedures. These scavengers can be directly applied to contaminated surfaces and immediately begin decontamination, reducing response time while avoiding the device complexity associated with more sophisticated decontamination systems.
