Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional array patch antenna is used, then it has high performance in a specific direction, but it cannot cover all directions
Solution Approach 1:
The antenna system is divided into multiple antenna units (first, second, third, and fourth antenna units) arranged in different directions. Each antenna unit handles a specific directional sector, and together they provide comprehensive 360-degree coverage. This segmentation allows the system to maintain high performance in each specific direction while achieving omnidirectional coverage.
Solution Approach 2:
Multiple antenna units with different directional characteristics are combined into a single integrated antenna system. The first antenna unit covers a first direction, the second antenna unit covers a second direction, the third antenna unit covers a third direction, and the fourth antenna unit covers a fourth direction. By merging these units, the system achieves both directional performance and omnidirectional coverage.
2Reliability
If a Teflon substrate or Rogers substrate is used, then performance consistency is improved, but product unit cost increases due to expensive material and processing costs
Solution Approach 1:
The patent replaces expensive Teflon or Rogers substrates with a cheaper alternative substrate material. While the alternative material may have different properties, the overall system design compensates for this through the waveguide structure and antenna unit configuration, achieving acceptable performance consistency at lower cost.
Solution Approach 2:
The patent changes the substrate material parameter from high-dielectric constant materials (Teflon, Rogers) to a different material with different dielectric properties. The waveguide structure and antenna design are optimized to work with this alternative material, maintaining performance through structural adjustments rather than relying solely on expensive substrate materials.
3Adaptability or versatility
If a waveguide system with multiple signal transmission paths is used, then directional coverage is improved, but device complexity increases
Solution Approach 1:
The waveguide system is segmented into multiple signal transmission paths (first, second, and third signal transmission paths), with each path leading to a different antenna unit. Separators are used to divide and direct signals along different paths. This segmentation provides multi-directional coverage while keeping each individual path relatively simple and manageable.
