Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mini card connector is built into a notebook computer, then the notebook can accommodate wireless module mini cards, but the connector can only support a certain type of wireless module mini card, limiting expansibility
Solution Approach 1:
The patent implements a universal card connector assembly that can accommodate multiple types of wireless module cards (PCI-Express mini cards and USB mini cards) through a single standardized interface design. The circuit board integrates multiple card connectors that support different card types, allowing one notebook computer to work with various wireless modules without requiring separate specialized connectors for each card type.
2Volume of moving object
If conventional notebook computers use standard card connectors, then they maintain simple design, but they cannot accommodate mini card format wireless modules
Solution Approach 1:
The patent divides the card connector functionality into separate modular components on the circuit board, including distinct card connectors for different card formats. This segmentation allows the notebook to support mini card formats while maintaining the simplicity of individual connector designs, as each connector is optimized for its specific card type rather than attempting a single complex universal interface.
3Adaptability or versatility
If a notebook computer lacks mini card connectors, then the design remains simple, but it cannot support wireless module mini cards
Solution Approach 1:
The patent merges multiple card connector functions into a single integrated card connector assembly mounted on the circuit board. By combining support for PCI-Express mini cards, USB mini cards, and SIM cards into one unified assembly, the design achieves multi-card compatibility while avoiding the complexity of separate independent connector systems, thus reducing overall device complexity.
