Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antibodies are used for PVY detection, then the detection method is established, but the reliability deteriorates due to instability under external physical or chemical factors
Solution Approach 1:
The patent uses M13KO7 bacteriophage as a substitute (copy) for antibodies in the detection system. The bacteriophage displays peptides on its surface that can specifically bind to PVY, replicating the detection function of antibodies while providing superior stability against physical and chemical degradation, thus resolving the reliability-stability contradiction
Solution Approach 2:
The patent changes the fundamental parameter of the detection reagent from protein-based antibodies to virus-based bacteriophage. This parameter change transforms the detection system's stability characteristics, as bacteriophage particles are inherently more resistant to denaturation by heat, pH changes, and other environmental factors compared to antibodies
2Stability of the object's composition
If M13KO7 bacteriophage is used for PVY detection, then the stability improves, but the manufacturing complexity increases
Solution Approach 1:
The M13KO7 bacteriophage system is self-replicating through infection of E. coli bacteria. The bacteriophage DNA contains the genetic information necessary to produce new phage particles, allowing for continuous production without complex manufacturing processes. The system uses the bacterial machinery to automatically assemble and replicate the detection reagents
Solution Approach 2:
The M13KO7 bacteriophage serves multiple functions: it acts as both the detection reagent (binding to PVY) and the production vehicle (self-replicating in E. coli). This multi-functionality simplifies the overall manufacturing process by eliminating the need for separate production and application stages
