Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If an omnidirectional antenna is adopted to extend coverage range, then the coverage distance is improved, but the radiation efficiency deteriorates and the device size increases
Solution Approach 1:
The antenna system is divided into multiple antenna units (first antenna unit, second antenna unit, etc.) arranged on different surfaces of the carrier structure. Each antenna unit covers a specific angular range, and collectively they achieve omnidirectional coverage while maintaining directional radiation efficiency for each segment.
Solution Approach 2:
Different antenna units are configured with different operational frequencies (first frequency and second frequency) and are arranged on different surfaces of the carrier structure. This local differentiation allows each antenna unit to optimize its radiation pattern for its specific coverage area while the overall system achieves comprehensive coverage.
2Area of moving object
If multiple antenna units with different frequencies are arranged on a carrier structure, then the coverage angle is improved, but the device complexity increases
Solution Approach 1:
Multiple antenna units with different frequencies are integrated onto a single carrier structure. The first antenna unit and second antenna unit are positioned on different surfaces of the same carrier, combining their coverage areas to achieve omnidirectional coverage while sharing common support and mounting structures.
Solution Approach 2:
The carrier structure serves multiple functions: it supports both the first antenna unit and second antenna unit, provides mechanical stability, and enables omnidirectional coverage through its three-dimensional arrangement of antenna units on different surfaces.
3Length of stationary object
If a direct broadcasting station amplifies relay information, then the signal coverage is improved, but self-excitation occurs easily when many ships are present, deteriorating internet surfing experience
Solution Approach 1:
Different antenna units operate at different frequencies (first frequency and second frequency) and are positioned to cover different angular ranges. This frequency differentiation and spatial separation prevent mutual interference and self-excitation between antenna units, allowing simultaneous operation without harmful interactions even when multiple terminals are present.
