Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stacked patch antennas with multiple dielectric materials are used, then antenna functionality for multiple frequency bands is achieved, but manufacturing complexity increases due to the need to control dielectric material variations
Solution Approach 1:
The patent uses a single dielectric substrate for both the first and second patch antennas, eliminating the need to control variations in multiple dielectric materials. This homogenization of materials simplifies the manufacturing process while maintaining multi-frequency band functionality through proper design of the patch antenna geometries and their relative positions on the same substrate.
2Reliability
If complicated manufacturing processes are implemented, then resonance frequency stability is improved, but manufacturing ease deteriorates
Solution Approach 1:
The patent achieves resonance frequency stability by optimizing geometric parameters (patch dimensions, spacing, feed line configurations) rather than relying on complex manufacturing processes to control dielectric material properties. This approach allows standard manufacturing techniques to be used while maintaining frequency stability through design optimization.
3Stability of the object's composition
If multiple dielectric materials with controlled variations are used, then antenna characteristics stability is improved, but manufacturing time and cost increase
Solution Approach 1:
By using a single dielectric substrate material for both antenna elements, the patent eliminates the need for complex multi-material assembly processes. This reduces manufacturing time and cost while achieving stable antenna characteristics through optimized geometric design of the patch antennas and their arrangement on the uniform substrate.
