Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an aqueous solution of metal compound is directly applied to substrate surface, then the process is simple and quick, but the metal compound cannot be stably retained and distribution is uneven
Solution Approach 1:
The patent introduces a silicon-containing polymer coating film as an intermediary layer between the substrate and metal compound. This polymer film serves as a mediator that provides stable retention sites for metal compounds through its chemical structure, solving the problem of unstable retention while maintaining efficient coating application.
Solution Approach 2:
The patent modifies the chemical parameters of the coating material by using silicon-containing polymers with specific molecular structures (polysiloxane or polysilane chains) that have been designed to bind metal compounds stably. This parameter change in material composition enables both stable retention and uniform distribution of metal compounds.
2Ease of manufacture
If an aqueous solution of metal compound is directly applied to substrate surface, then the application process is simple, but the amount of metal compound retained is uneven
Solution Approach 1:
The silicon-containing polymer acts as an intermediary that uniformly distributes metal compounds across the substrate surface. The polymer's molecular structure provides consistent binding sites, ensuring even metal compound distribution while maintaining simple application processes.
Solution Approach 2:
The patent employs silicon-containing polymers with homogeneous molecular structures that provide uniform binding characteristics. This homogeneity in the polymer structure ensures even distribution of metal compounds across the coating film, achieving precise manufacturing results.
3Ease of manufacture
If conventional polymer coating is used, then the coating film can be formed, but it cannot stably support metal compounds
Solution Approach 1:
The patent changes the chemical parameters of the polymer by using silicon-containing polymers (polysiloxane or polysilane) with specific functional groups that have high affinity for metal compounds. This parameter change enables the coating film to stably support metal compounds while maintaining ease of film formation.
Solution Approach 2:
The patent uses composite material structure where silicon-containing polymer chains are combined with metal compounds. This composite approach creates a synergistic effect where the polymer provides stable support and the metal compounds achieve reliable retention, overcoming the limitations of conventional polymers.
