Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If radome and antenna are manufactured as separate structures, then manufacturing flexibility and ease of assembly are improved, but spacing variations occur that degrade antenna performance
Solution Approach 1:
The patent merges the radome and antenna into a single integrated structure where the antenna elements are embedded within the radome body. This integration eliminates the separate manufacturing and assembly process, thereby removing spacing variations while maintaining manufacturing flexibility through composite material molding techniques.
Solution Approach 2:
The antenna elements are nested within the radome structure, with radiating elements positioned inside the composite material layers. This nesting approach allows the antenna to be housed within the radome volume, achieving precise spacing control through the molding process while preserving the protective function of the radome.
2Ease of manufacture
If radome and antenna are manufactured as separate structures, then ease of assembly is improved, but overall space requirement increases
Solution Approach 1:
By combining the radome and antenna into a single integrated component, the patent eliminates the need for separate structures and the spacing gap between them. This merging reduces the overall volume occupied by the antenna system while simplifying assembly into a single unit.
3Manufacturing precision
If integrated composite structure is used, then spacing precision is improved, but device complexity increases
Solution Approach 1:
The patent employs composite materials (fiber-reinforced polymers) to create the integrated radome-antenna structure. The composite layers are molded with embedded antenna elements, achieving precise spacing through the material formulation and molding process while the layered composite structure provides both mechanical strength and electromagnetic transparency.
4Ease of repair
If separate radome and antenna structures are used, then ease of repair is improved, but reliability decreases due to environmental interference
Solution Approach 1:
The integrated structure provides continuous environmental protection as the radome material forms an unbroken barrier around the antenna elements. There are no gaps or interfaces between separate components where environmental interference could penetrate, thereby improving reliability through enhanced protection.
