Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If outer metal and inner metal are joined by welding only the end surfaces, then manufacturing is simplified, but welding defects occur at contact points reducing antenna performance
Solution Approach 1:
The invention transitions from welding only at the end surfaces (one-dimensional contact) to welding at multiple locations including side surfaces and through-holes (multi-dimensional contact). The protrusions extend into through-holes of the other metal member, creating three-dimensional bonding zones that eliminate welding defects while maintaining manufacturing feasibility.
Solution Approach 2:
The welding process is segmented into multiple discrete welding locations rather than a single continuous weld. Protrusions are formed at specific intervals along the metal members, creating separate welding zones at each protrusion tip and side surface, which prevents defect propagation and ensures consistent antenna performance.
2Reliability
If multiple protrusions and through-holes are added to increase bonding area, then durability and antenna performance improve, but device complexity increases
Solution Approach 1:
The invention merges the functions of protrusions and through-holes into an integrated coupling mechanism. The protrusions and through-holes work together as a unified system where protrusions from one metal member fit into through-holes of the other, creating interlocking bonding zones that simultaneously achieve durability and antenna performance without requiring separate fastening mechanisms.
Solution Approach 2:
The metal members are designed with multi-functionality: the protrusions and through-holes serve both mechanical bonding purposes (increasing durability) and electrical connection purposes (maintaining antenna performance). This universal design eliminates the need for separate structural and electrical components, reducing overall device complexity.
