Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional shielding connection structures are used to butt two cables, then the cable assembly can be manufactured with simple structures, but the shielding connection between the two cables is unstable and ineffective, failing to ensure electromagnetic shielding effect
Solution Approach 1:
The shielding connection assembly is divided into multiple components: first shielding internal device, first shielding middle device, second shielding internal device, and second shielding middle device. Each component performs a specific function in the connection process, allowing for stable and effective shielding connection while enabling modular manufacturing and assembly.
Solution Approach 2:
The shielding connection devices are nested within the cable assembly structure, with the first and second shielding internal devices positioned inside the respective cables and the middle devices connecting them. This nested arrangement ensures stable shielding connection while maintaining a compact overall structure.
2Ease of manufacture
If simple shielding connection structures are used, then manufacturing is easier, but the electromagnetic shielding effect between cable cores is insufficient due to unstable shielding net connection
Solution Approach 1:
The first and second shielding middle devices act as intermediary components that connect the shielding nets of the two cables. These middle devices provide a stable connection interface, ensuring effective electromagnetic shielding while maintaining ease of manufacture through standardized connection mechanisms.
Solution Approach 2:
The shielding connection assembly replaces traditional mechanical fastening methods with a integrated crimping and welding system. The shielding middle devices are crimped to the cable cores and welded to the shielding nets, providing stable electrical and mechanical connection that effectively reduces electromagnetic interference.
3Strength
If shielding layers are connected without everted portions, then the structure is simpler, but the stress strength between shielding layers and conductive devices is insufficient
Solution Approach 1:
The shielding layers are everted (folded back) before the connection process, creating pre-formed connection surfaces that facilitate stable attachment of the conductive devices. This preliminary action ensures adequate stress strength in the final connection while maintaining a manageable structure during assembly.
