Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional socket designs are used without integrated RF shielding, then device complexity is reduced and ease of manufacture is improved, but radio frequency interference disrupts system performance and data integrity
Solution Approach 1:
The patent combines the socket structure with RF shielding components into a single integrated assembly. The shield socket includes tab shield portions coupled to a printed circuit board, an extension shield portion with clips, and pins with tabbed features that contact the clips. This merging of socket and shielding functions eliminates the need for separate shielding components, thereby improving reliability by reducing RF interference while avoiding the complexity of multiple discrete parts.
Solution Approach 2:
The socket is designed to perform multiple functions simultaneously: electrical connection through pins and reliable RF shielding through integrated shield portions. The tab shield portions and extension shield portion with clips provide grounding paths for RF signals while the pins provide electrical connectivity. This multi-functionality ensures both data integrity and electromagnetic compatibility within a single component.
2Object-affected harmful factors
If RF shielding components are added to the socket, then radio frequency interference is reduced, but manufacturing complexity increases
Solution Approach 1:
By integrating the RF shielding components directly into the socket structure during manufacturing, the patent eliminates the need for separate assembly steps. The tab shield portions are coupled to the printed circuit board, and the extension shield portion with clips is formed as part of the socket body. This unified manufacturing approach reduces the number of parts and assembly operations, thereby improving ease of manufacture while providing effective RF shielding.
3Object-affected harmful factors
If a grounded path for RF signals is provided, then RF interference is minimized, but the socket structure becomes more complex
Solution Approach 1:
The grounded path for RF signals is integrated into the socket structure through the tab shield portions and extension shield portion. These conductive elements are coupled to the printed circuit board and provide a direct grounding path for RF interference. By merging the grounding function into the existing socket structure rather than adding separate grounding components, the patent achieves effective RF interference minimization without significantly increasing structural complexity.
