Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer conductor is formed by bending a metal plate, then the manufacturing process is simple, but gaps are formed and shielding performance deteriorates
Solution Approach 1:
The outer conductor is divided into two separate parts: a first outer conductor (tubular structure) and a second outer conductor (plate-shaped structure). The first outer conductor provides continuous shielding coverage, while the second outer conductor is easier to manufacture and assemble. This segmentation allows each part to optimize its manufacturing method while maintaining overall shielding performance.
Solution Approach 2:
The second outer conductor is inserted into the first outer conductor, forming a nested structure. The first outer conductor acts as an inner tube while the second outer conductor acts as an outer plate structure. This nesting arrangement allows the tubular first outer conductor to provide continuous shielding while the plate-shaped second outer conductor provides additional shielding and structural support, eliminating gaps that would occur with bending alone.
2Ease of manufacture
If the outer conductor is formed by bending a metal plate, then manufacturing cost is low, but dimensional precision and gap control worsen
Solution Approach 1:
By segmenting the outer conductor into two parts with different manufacturing methods, the first outer conductor can be precisely formed using drawing or rolling processes that maintain tight dimensional tolerances, while the second outer conductor can be manufactured more economically using plate bending or stamping. This segmentation allows cost-effective manufacturing without sacrificing the dimensional precision needed to prevent gaps.
Solution Approach 2:
Different portions of the outer conductor system have different quality requirements. The first outer conductor (tubular part) requires high dimensional precision and continuous surface quality for optimal shielding, while the second outer conductor (plate part) can tolerate broader dimensional variations. By applying different manufacturing processes to different parts according to their specific quality needs, overall precision is maintained where critical while cost is reduced where less critical.
3Reliability
If a tubular structure is used for the first outer conductor, then shielding performance is improved, but device complexity increases
Solution Approach 1:
The complex shielding structure is segmented into two functional parts: a tubular first outer conductor for primary shielding and a plate-shaped second outer conductor for secondary shielding and structural support. This segmentation allows the complex tubular structure to be simplified in manufacturing (using standard drawing or rolling processes) while the plate structure provides a simple interface for connection and assembly, reducing overall device complexity.
Solution Approach 2:
The nested arrangement of the tubular first outer conductor and plate-shaped second outer conductor creates a compact, integrated structure. The first outer conductor fits within or alongside the second outer conductor, forming a unified assembly that appears simple from the outside while providing enhanced shielding performance. This nesting eliminates the need for complex fastening mechanisms or additional support structures.
