Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are connected to connection terminals through wiring and via holes, then data transmission is enabled, but signal integrity is reduced and impedance becomes unstable
Solution Approach 1:
The patent extracts the chip from the server motherboard and places it on a riser board, removing the problematic wiring and via holes from the signal path. The cable connects directly to the chip through the riser board's conductive structure, eliminating the intermediate connection terminals that caused signal integrity issues.
Solution Approach 2:
The riser board acts as an intermediary between the cable and the server motherboard, providing a direct conductive path that bypasses the problematic wiring and via holes of the motherboard. This mediator structure maintains signal integrity while enabling flexible cable connections.
2Adaptability or versatility
If a large number of connection terminals are used to connect all cables, then all cables can be connected, but miniaturization and lightweight design cannot be achieved
Solution Approach 1:
The riser board is designed with multi-functional capabilities, serving as both a support structure for the chip and a connection interface for multiple cables. The conductive structure integrates multiple functions into a single component, reducing the need for separate connection terminals and enabling miniaturization.
3Productivity
If chips are mounted on the server motherboard, then direct chip-to-chip forwarding is enabled, but chip mounting and maintenance are inconvenient due to limited space
Solution Approach 1:
The system is segmented into separate functional modules: the server motherboard, the riser board with chip, and the cable connector. This segmentation allows the chip to be mounted on a separate riser board that can be easily installed and maintained, while still enabling direct chip-to-chip forwarding through the riser board's conductive structure.

AI summary
A cable connector includes: a circuit board; at least one plastic body, fixed on the circuit board, and provided therein with a first socket; a chip, provided on the circuit board; a first set of conductive terminals, held in the first socket of the plastic body, and including first signal terminals; first signal cables, each including one end electrically connected to the first signal terminal and the other end connected to the circuit board and conductively connected to the chip; and a first signal transmission component, conductively connected to the chip. The chip is provided on the circuit board of the cable connector, which achieves convenient mounting and maintenance of the chip. In addition, the cable connector achieves signal function control and configuration through the chip, and thus can achieve multi-performance expansion, improving the access efficiency.
