Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If complex interconnection network topologies (Dragonfly, Flattened Butterfly, etc.) are used to achieve high network performance and scalability, then network capability is improved, but wiring complexity and installation difficulty increase significantly

Engineering Contradiction:
Improvenetwork performanceVSAvoidwiring complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the interconnection network into multiple Complete Interconnection Network (CIN) layers, where each layer provides specific connectivity functions. This segmentation allows complex network topologies to be built from simpler, standardized building blocks, reducing overall wiring complexity while maintaining high performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements nested CIN structures where multiple CIN layers are stacked and interconnected through vertical wiring. Each CIN layer is self-contained with complete connectivity, and layers are nested within a hierarchical framework, allowing complex network functionality to emerge from simpler nested components.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If wiring arrangements for CIN-based networks are optimized to reduce wire crossings, then ease of installation and maintenance is improved, but routing complexity may increase

Engineering Contradiction:
Improveinstallation easeVSAvoidrouting complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent resolves wire crossing issues by transitioning from a two-dimensional plane to a three-dimensional stacked architecture. CIN layers are arranged vertically, allowing connections that would cross in 2D to be routed through different vertical levels, eliminating crossings while maintaining routing efficiency through structured inter-layer connections.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces intermediate connection layers and standardized interface structures that mediate between different CIN layers. These intermediaries provide systematic routing paths, reducing the need for complex direct point-to-point routing while simplifying installation through standardized connection procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of repair

If wire connections are organized in parallel guides without crossings, then ease of repair and maintenance is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvemaintenance easeVSAvoidalignment precision
Core Design Contradiction:
Ease of repairVSManufacturing precision

Solution Approach 1:

The patent incorporates alignment features, guide structures, and positioning mechanisms during the CIN layer fabrication process. Wire guides and connection interfaces are pre-configured with alignment tolerances built into the manufacturing process, ensuring that parallel wire arrangements can be assembled with appropriate precision while maintaining ease of maintenance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent specifies particular parameter ranges for wire spacing, guide dimensions, and alignment tolerances that balance manufacturing precision requirements with maintenance ease. By optimizing these parameters within defined ranges, the system achieves sufficient precision for reliable operation while maintaining practical manufacturability and serviceability.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention relates to a system for connecting multi-dimensional HyperX networks. In a 1D HyperX, or Complete Interconnection Network, CIN, there is a link between any pair of switches, wherein the network comprises a plurality of servers arranged in a plurality of computer groups; wherein each computer group is connected to a connection switch. Advantageously, in this way, wires are grouping in parallel sets or guides and wherein the wire connections are arranged without crossings between said parallel guides. The invention can also be applied to hierarchical and multi-dimensional networks built upon CINs, either per network layer or per dimension, respectively, using additional horizontal dimensions (X, Y) for deploying parallel hoses of wires, arranged without crossings. The invention further relates to a compact routing mechanism which is derived from the proposed connection pattern when the number of switches in the system is a power of 2.
