Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-processor server node cross-board signal interconnection solutions require large vertical middle backboards, leading to increased heat dissipation issues and signal loss due to multiple high-speed connectors, which hinder rapid disassembly and maintenance.
Innovation Solution
A multi-processor server node cross-board signal interconnection device with first and second signal connectors arranged on the surface and back of a middle backboard, respectively, connected by signal interconnection cables, optimizing space usage and reducing signal transfer levels and losses by eliminating inter-board signal connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional high-speed connectors are used for cross-board signal interconnection, then signal connection is achieved, but mounting space occupation increases and signal loss increases due to multiple transfer levels
Solution Approach 1:
The patent transitions from horizontal signal routing on the board surface to vertical signal routing through the board thickness. High-speed connectors are arranged vertically on the middle backboard, allowing signals to pass through the board rather than traveling along its surface. This dimensional change reduces the horizontal space occupation while maintaining signal connection reliability.
2Adaptability or versatility
If multiple high-speed connectors are arranged on the middle backboard, then signal interconnection is achieved, but heat dissipation space is reduced and system stability deteriorates
Solution Approach 1:
By arranging connectors vertically through the board rather than horizontally on the surface, the patent frees up horizontal space that can be used for heat dissipation air ducts and thermal management features. The vertical arrangement allows signals to pass through the board thickness, reducing the horizontal footprint of connector arrangements.
3Ease of operation
If traditional horizontal board arrangement with vertical middle backboard is used, then signal interconnection is achieved, but signal transfer levels increase and signal loss increases
Solution Approach 1:
The patent extracts the signal transmission path from the traditional multi-level board routing and consolidates it into a direct vertical path through the middle backboard. By removing intermediate horizontal routing segments and using vertical connectors that pass through the board, the signal transfer path is shortened and simplified, reducing signal loss.
4Reliability
If cables are used for signal interconnection, then signal loss is reduced, but cable arrangement complexity increases and layout flexibility is reduced
Solution Approach 1:
The patent merges the cable function directly into the middle backboard structure by integrating high-speed connectors and signal routing paths within the board itself. This consolidation eliminates the need for separate external cables, reducing arrangement complexity while maintaining the low signal loss benefits of direct cable-like connections.

AI summary
Disclosed is a multi-processor server node cross-board signal interconnection device. The device includes a middle backboard, a plurality of first signal connectors arranged on a surface of the middle backboard, a plurality of second signal connectors arranged on a back surface of the middle backboard and having the same distribution region as all the first signal connectors, a plurality of signal leading-out terminals arranged on all node single boards and configured to be connected to all the second signal connectors, and a plurality of signal interconnection cables connected between the second signal connectors. In this way, all the second signal connectors transmit signals on the middle backboard by means of the signal interconnection cables. All the second signal connectors and the first signal connectors are arranged in the same region, such that a risk of signal interference is eliminated.
