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 gap formation occurs and shielding performance deteriorates
Solution Approach 1:
The outer conductor is divided into a first outer conductor (tubular member formed by casting or cutting) and a second outer conductor (plate-shaped member), which are electrically connected to each other. The tubular first outer conductor prevents gap formation and ensures shielding performance, while the plate-shaped second outer conductor maintains manufacturing simplicity.
Solution Approach 2:
The outer conductor combines two different structural forms: a tubular first outer conductor formed by casting or cutting (which prevents gaps) and a plate-shaped second outer conductor (which is easy to manufacture). These two parts are electrically connected to create a composite structure that achieves both shielding performance and manufacturing ease.
2Ease of manufacture
If the outer conductor is formed by bending a metal plate, then manufacturing costs are reduced, but gap formation compromises shielding effectiveness
Solution Approach 1:
The outer conductor is segmented into two functional parts: the first outer conductor (tubular) that eliminates gaps and ensures shielding effectiveness, and the second outer conductor (plate-shaped) that is cost-effective to manufacture. This segmentation allows each part to optimize its specific function.
Solution Approach 2:
Different parts of the outer conductor have different structural qualities: the first outer conductor uses a tubular structure (formed by casting or cutting) where gap-free continuity is critical for shielding, while the second outer conductor uses a plate-shaped structure where cost-effectiveness is prioritized. Each local region has the quality needed for its specific function.
3Reliability
If a tubular outer conductor is formed by casting or cutting, then shielding performance is improved, but manufacturing complexity increases
Solution Approach 1:
The complex tubular structure is separated into the first outer conductor (tubular, formed by casting or cutting) and the second outer conductor (plate-shaped). This segmentation allows the complex tubular structure to be limited to only where needed (first outer conductor) while the rest uses simpler plate structures.
Solution Approach 2:
The first outer conductor (tubular) and second outer conductor (plate-shaped) are merged by electrical connection to form a complete outer conductor system. This combining allows the system to achieve the shielding performance of a full tubular structure while using simpler plate structures in parts, reducing overall manufacturing complexity.
