Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If copper ions are used for antibacterial and antiviral purposes, then high antibacterial and antiviral effects are achieved, but toxicity to the human body increases
Solution Approach 1:
The patent replaces copper ions with cobalt ions that form self-assembled complexes with body-derived ligands. These complexes provide the necessary antibacterial and antiviral effects while being non-toxic to the human body, effectively substituting a harmful short-living approach with a safe sustainable alternative
Solution Approach 2:
The patent introduces self-assembled complexes as intermediaries between the metal ions and the biological system. These complexes, formed with body-derived ligands, mediate the interaction between cobalt/silver ions and biological targets, providing antibacterial and antiviral effects while preventing direct toxic interactions with human cells
2Object-affected harmful factors
If silver nanoparticles are used for antibacterial purposes, then antibacterial effects are achieved, but production cost increases
Solution Approach 1:
The patent employs self-assembled complexes that form automatically through the natural affinity between metal ions and body-derived ligands. This self-assembly process eliminates the need for complex nanoparticle synthesis procedures, significantly reducing production costs while maintaining antibacterial effectiveness
Solution Approach 2:
The patent replaces expensive silver nanoparticles with cobalt-based self-assembled complexes that are more cost-effective to produce. The complexes provide comparable or superior antibacterial effects at a lower production cost, making the technology more accessible and scalable
3Measurement precision
If antigen-antibody reaction is used for cancer targeting, then specific binding to cancer tissue is achieved, but device complexity and production cost increase
Solution Approach 1:
The patent extracts and utilizes ligands that naturally exist in the body to form self-assembled complexes with metal ions. These complexes inherently possess the ability to target cancer cells through the natural affinity of the ligands for cancer cell surfaces, eliminating the need for complex antigen-antibody systems and additional processing
Solution Approach 2:
The patent creates a universal platform where self-assembled complexes can target different types of cancer cells by utilizing the natural diversity of body-derived ligands. This single platform approach provides both diagnostic and therapeutic functions, replacing the need for multiple specialized antigen-antibody systems
4Object-generated harmful factors
If cobalt ions are used to form complexes in the body, then low toxicity is achieved, but difficulty in applying to various substances and forming complexes increases
Solution Approach 1:
The patent utilizes the natural ability of body-derived ligands to self-assemble with cobalt ions. This self-assembly process occurs spontaneously within the body, allowing cobalt ions to form complexes with various biological molecules without requiring external intervention or complex synthesis procedures, thereby maintaining low toxicity while achieving versatility
