Solution Overview
Problem
Conventional half-sized PCI CPU cards lack the ability to expand PCIe peripherals due to their limited size, preventing the integration of high-speed PCIe bus compatible expansion slots.
Innovation Solution
A half-sized PCI CPU card with a golden finger compatible with both PCI and PCIe standards is designed, allowing insertion into corresponding slots on a backplane, which includes additional PCIe expansion slots for enhanced expandability, enabling communication with PCIe peripherals through expansion circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the half-sized PCI CPU card uses conventional PCI bus standard, then the card size is kept small and simple, but the capability to expand PCIe peripherals is lost
Solution Approach 1:
The half-sized PCI CPU card integrates both PCI and PCIe bus standards into a single card design. The card includes a PCI bus interface for compatibility with existing PCI peripherals and a PCIe bus interface for high-speed expansion, allowing the same card to support multiple bus standards and peripheral types without requiring separate cards for each functionality.
Solution Approach 2:
The card is divided into distinct functional sections: a PCI bus interface section for traditional PCI connections, a PCIe bus interface section for high-speed expansion, and a processing unit section. This segmentation allows each section to be optimized for its specific bus standard while maintaining overall card functionality and compact size.
2Speed
If PCIe expansion slots are added to the half-sized PCI CPU card, then the transmission rate is improved, but the card size increases
Solution Approach 1:
The PCIe expansion slot is positioned at a different spatial dimension relative to the PCI bus interface. By arranging the PCIe slot adjacent to but separate from the PCI interface area, the design utilizes vertical or lateral space efficiency, allowing high-speed expansion capability to be added without proportionally increasing the card's footprint area.
Solution Approach 2:
The PCIe expansion slot is integrated into the existing half-sized PCI CPU card structure rather than being a separate add-on card. The card combines the PCI bus interface, PCIe bus interface, and processing unit into a single unified component, merging multiple functions into one compact unit that maintains small card area while providing high-speed transmission capability.
3Adaptability or versatility
If a golden finger compatible with both PCI and PCIe standards is used, then the compatibility is improved, but the manufacturing complexity increases
Solution Approach 1:
The golden finger is designed with a universal structure that can interface with both PCI and PCIe bus standards. By incorporating contact elements that are compatible with both standards, the same golden finger can establish connections for either PCI or PCIe operations, eliminating the need for separate golden fingers for each standard and simplifying the overall manufacturing process despite the enhanced compatibility requirements.
