Engineering Contradiction Analysis
1Speed
If the data transfer rate of the circuit board for interconnect is increased by using a dielectric material with a small dielectric loss or by increasing the number of layers, then the data transfer rate between circuit board units is improved, but the production costs increase and the wiring becomes complex
Solution Approach 1:
The invention divides the signal transmission path into two segments: high-speed signals are transmitted through cables connected to circuit board units, while control signals are transmitted through the circuit board for interconnect. This segmentation allows high-speed data transfer without requiring complex high-speed wiring throughout the entire system.
Solution Approach 2:
The invention introduces cables as an intermediary medium for high-speed signal transmission between circuit board units. The cables serve as a dedicated high-speed transmission path, eliminating the need to upgrade the entire circuit board for interconnect infrastructure.
2Speed
If the data transfer rate of the circuit board for interconnect is increased by using a dielectric material with a small dielectric loss or by increasing the number of layers, then the data transfer rate between circuit board units is improved, but the production costs increase
Solution Approach 1:
The invention extracts the high-speed transmission requirement from the circuit board for interconnect and implements it separately through cables connected to circuit board units. This allows the majority of the system to use standard, cost-effective components while achieving high-speed performance where needed.
Solution Approach 2:
The invention uses standard cables as a temporary or replaceable solution for high-speed transmission, which are generally less expensive than custom-designed high-speed circuit boards. The cables can be easily replaced or upgraded without replacing entire circuit board units.
3Speed
If connectors are positioned on the circuit board unit to enable cable coupling, then the data transfer rate is improved, but the packaging density may be reduced
Solution Approach 1:
The invention positions connectors on the side surface of circuit board units rather than on the top or bottom surfaces. This utilizes the vertical dimension and side space, preserving the valuable top and bottom surface areas for component mounting and maintaining packaging density.
