Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radome assembly is designed to protect antennas from environmental conditions, then reliability is improved, but device complexity increases due to multiple layers and materials
Solution Approach 1:
The radome assembly is divided into distinct functional layers: an outer layer for environmental protection, a radome body portion for structural support, and a radome spacer portion for positioning. This segmentation allows each layer to be optimized for its specific function while simplifying the overall design process and manufacturing.
Solution Approach 2:
The patent employs composite material construction with an outer layer made from one material and the radome body portion made from another material. This composite approach enables the assembly to simultaneously achieve environmental protection, structural integrity, and electrical performance without requiring a single complex material system.
2Reliability
If an outer layer with hydrophobic properties is added to protect from moisture, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The outer layer is implemented as a thin film structure with hydrophobic properties that can be applied to the radome body portion. This thin film approach provides effective moisture protection while maintaining ease of manufacturing through simple coating or lamination processes, avoiding complex multi-step manufacturing procedures.
3Manufacturing precision
If a radome spacer portion is added to space the radome body from antenna elements, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The radome spacer portion is integrated with the radome body portion to form a unified structure. This merging eliminates the need for separate spacer components and assembly steps, achieving precise spacing between the radome body and antenna elements while actually reducing overall device complexity compared to using discrete spacer parts.
