Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional linear or simple branched silicones are used, then the basic silicone properties are maintained, but the molecular shape control and functional versatility are limited
Solution Approach 1:
The patent segments the molecular structure into distinct functional modules: a core silicones unit, branching units with controlled functionality, and optional end-cap units. This modular segmentation allows independent optimization of each component to achieve desired molecular shapes and functionalities without overwhelming complexity
Solution Approach 2:
The patent creates universal building blocks (core units, branching units, end-cap units) that can be combined in various configurations to produce different molecular shapes and functionalities. The branching units can serve multiple purposes: controlling molecular shape, providing functional groups, and adjusting physical properties, thereby achieving multi-functionality through a single versatile component
2Manufacturing precision
If complex branched structures are synthesized through multiple steps, then molecular shape control is improved, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent employs preliminary action by pre-synthesizing and characterizing standardized core units, branching units, and end-cap units before final assembly. These pre-prepared building blocks with known structures and functionalities can be directly combined to achieve desired molecular shapes, eliminating the need for complex step-by-step synthesis during production and significantly improving synthesis efficiency
3Adaptability or versatility
If highly branched dendritic structures are created, then molecular functionality and reactivity are enhanced, but the structural control and uniformity become more difficult to achieve
Solution Approach 1:
The patent applies local quality by assigning specific functionalities to specific regions of the molecule: the core unit provides the central framework, branching units contribute specific functional groups at defined locations, and end-cap units terminate branches with controlled properties. This localized functional assignment allows precise control over molecular functionality while maintaining overall structural control and uniformity through systematic design of each region
