Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional antenna devices are used, then device complexity is reduced, but electromagnetic wave loss increases and emission efficiency deteriorates
Solution Approach 1:
The antenna device is divided into multiple functional units, each comprising integrated substrates with specific dielectric and conductive layers. This segmentation allows optimization of electromagnetic wave transmission in each unit while maintaining overall system manageability and reducing total energy loss.
Solution Approach 2:
The patent employs composite structures combining dielectric layers with specific loss tangent values (≤0.1) and conductive layers in alternating arrangements. This composite material approach minimizes electromagnetic wave loss by selecting materials with complementary properties optimized for high-efficiency emission.
2Productivity
If multi-layered dielectric and conductive structures are implemented, then emission efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
By dividing the antenna into discrete units with standardized multi-layer structures, the manufacturing process can be modularized. Each unit can be fabricated and tested independently before assembly, reducing the cumulative precision requirements compared to manufacturing a monolithic structure.
Solution Approach 2:
The patent specifies particular parameter ranges for dielectric layers (loss tangent ≤0.1) and conductive layers to optimize emission efficiency. By establishing clear parameter specifications, the design allows for standardized manufacturing processes that can achieve high precision through controlled parameter ranges rather than requiring extreme dimensional accuracy.
3Loss of energy
If dielectric layers with low loss tangent are used, then electromagnetic wave loss is reduced, but material selection and manufacturing complexity increase
Solution Approach 1:
The patent establishes a specific parameter threshold (loss tangent ≤0.1) for dielectric materials to ensure low electromagnetic wave loss. This quantitative specification enables systematic material selection and standardized manufacturing processes, balancing performance requirements with manufacturing feasibility by focusing on achievable parameter ranges rather than extreme material properties.
