Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional methods are used to prepare oxidation-reduction polymers with transition metal complexes, then the polymer can be prepared, but the preparation process is complex and the immobilization rate is low
Solution Approach 1:
The patent changes the chemical reaction parameters by using click chemistry (azide-alkyne cycloaddition) instead of conventional coupling reactions. This parameter change simplifies the preparation process by providing high reactivity, selective bonding, and tolerance to various functional groups, thereby resolving the contradiction between ease of manufacture and device complexity
Solution Approach 2:
The patent creates a composite structure by combining the polymer backbone with transition metal complexes through click chemistry. This composite approach allows the polymer to maintain its structural integrity while achieving high immobilization rates of the metal complexes, solving the contradiction between simple preparation and complex device structure
2Reliability
If conventional methods are used to prepare oxidation-reduction polymers, then the polymer can be synthesized, but the immobilization rate of transition metal complexes is low
Solution Approach 1:
The patent extracts the key functional requirement (high immobilization rate) from the complex conventional synthesis process by using click chemistry. This approach isolates the essential bonding mechanism, achieving high immobilization rates without the need for complex multi-step synthesis procedures, thereby resolving the contradiction between reliability and productivity
3Adaptability or versatility
If conventional methods are used, then the polymer structure can be formed, but it is difficult to introduce functional groups or linkers
Solution Approach 1:
The patent applies the universality principle by using click chemistry as a versatile bonding platform that can accommodate various functional groups and linkers. The azide-alkyne cycloaddition reaction is compatible with diverse chemical groups, allowing the introduction of different functional moieties without increasing synthesis complexity, thus resolving the contradiction between adaptability and device complexity
