Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional materials are used in 5G electronic devices, then manufacturing and device construction are straightforward, but the materials interfere with high-band wavelengths and do not perform well at 5G frequencies
Solution Approach 1:
The patent changes the chemical composition parameters of the material by using carbosilane polymers with specific molecular structures and compositions that inherently provide low dielectric properties, thereby achieving compatibility with 5G frequencies without wavelength interference
Solution Approach 2:
The patent employs composite material formulation by combining carbosilane polymers with specific additives and catalysts to create a curable composition that achieves the desired low dielectric constant and low loss tangent properties required for 5G applications
2Reliability
If the curable composition is formulated with specific carbosilane components, then low dielectric constant and low dielectric loss are achieved, but the formulation complexity increases
Solution Approach 1:
The patent segments the material formulation into distinct functional components: carbosilane polymer base, vinyl functional groups for crosslinking, and hydrosilylation catalysts. This segmentation allows each component to be optimized independently while maintaining overall formulation manageability
Solution Approach 2:
The carbosilane polymer serves multiple functions simultaneously: it provides the base polymer matrix, contributes to the low dielectric properties through its molecular structure, and enables crosslinking through vinyl groups. This multi-functionality reduces the need for additional separate additives, simplifying the overall formulation
3Ease of operation
If low viscosity is achieved for inkjet printing, then dispensing ease is improved, but material composition constraints increase
Solution Approach 1:
The patent adjusts the viscosity parameter of the curable composition by controlling polymer molecular weight, chain length, and composition ratios to achieve a viscosity range specifically suited for inkjet printing, while maintaining the required dielectric properties through careful formulation balancing
