Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive substrates (glass, metals, plastics) are used for mechanical support, then structural stability is ensured, but functional interaction with electronic elements is lost
Solution Approach 1:
The substrate material parameters are changed from passive mechanical properties to active functional properties. The substrate is designed with specific magnetic permeability, piezoelectric coefficients, or other functional parameters that enable interaction with electronic elements, transforming it from a purely mechanical support to an active functional component
Solution Approach 2:
The substrate is designed to perform multiple functions simultaneously: mechanical support, electromagnetic shielding, signal transmission, or sensing. This multi-functionality allows the same substrate structure to provide both structural stability and functional interaction, eliminating the need for separate functional layers
2Adaptability or versatility
If functional materials are integrated into the substrate, then device functionality is enhanced, but manufacturing complexity increases
Solution Approach 1:
Multiple functional layers or materials are merged into a single integrated substrate structure. Instead of assembling separate mechanical and functional components, the substrate is designed as a unified structure that inherently provides both mechanical support and functional interaction, simplifying the manufacturing process
Solution Approach 2:
Composite substrate materials are used that combine multiple functional properties in a single material system. For example, a composite material may simultaneously provide mechanical strength, magnetic properties, and piezoelectric effects, reducing the need for multiple separate materials and layers
