Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple layers of IP switches and cabled Ethernet connections are used to interconnect shared resources, then network connectivity and resource sharing are achieved, but physical space consumption, energy usage, and system complexity increase significantly

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent transitions from traditional two-dimensional rack mounting with cabled connections to a three-dimensional architecture where switch bars are stacked vertically and interconnected through orthogonal connections. This dimensional change eliminates the need for extensive cabling and reduces physical footprint while maintaining network connectivity capabilities.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent integrates multiple functions into the switch bar architecture by combining switching capabilities, connectivity interfaces, and interconnection mechanisms into unified modular units. This merging eliminates separate cabling infrastructure and reduces the overall system volume while preserving network interconnectivity.

Inventive Principle:

2Adaptability or versatility

If multiple layers of IP switches and Ethernet cabling are deployed, then comprehensive network interconnection is achieved, but energy consumption and operational costs increase

Engineering Contradiction:

Improvenetwork interconnectionVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by stationary object

Solution Approach 1:

The patent extracts and eliminates the energy-consuming cabling infrastructure from the network architecture by replacing it with direct orthogonal connections between switch bars. This extraction removes the intermediate cabling layer that consumes energy while maintaining the essential network interconnection function.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical cabling system with a direct structural connection system where switch bars connect orthogonally through integrated interfaces. This substitution eliminates the energy required for signal transmission through cables while maintaining network interconnectivity.

Inventive Principle:
