Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual processes are used to modify switch fabric, then flexibility and control are maintained, but time consumption and error rate increase

Engineering Contradiction:
Improveerror rateVSAvoidtime consumption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The switch fabric modification system performs self-verification of connectivity and self-correction of configuration parameters. The system automatically detects connectivity status, verifies operating parameters, and adjusts configurations without external intervention, enabling the system to service itself and eliminate manual errors while maintaining operational control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback loops where connectivity verification results and operating parameter measurements are fed back to the control logic. This feedback mechanism enables automatic adjustment of switch fabric configurations based on real-time system state, reducing both time consumption and error rates through closed-loop control

Inventive Principle:
Principle #23Feedback

2Productivity

If automated verification processes are implemented, then modification speed increases, but system complexity increases

Engineering Contradiction:
Improvemodification speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated verification process is divided into distinct modular segments: connectivity verification module, operating parameter verification module, and configuration addition module. Each segment handles a specific verification task independently, which reduces overall system complexity while maintaining high modification speed through parallel processing of these segmented functions

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary verification of connectivity and operating parameters before actually adding the new switch to the fabric. This preliminary action ensures that all necessary checks are completed in advance, enabling rapid modification execution without complex real-time decision-making during the actual addition process

Inventive Principle:
Principle #10Preliminary action

AI summary

A switch fabric modification system includes a switch fabric having first switch devices and a primary switch device. The primary switch device detects a second switch device has been connected to the switch fabric and, in response and without subsequently receiving an instruction from a user, verifies a second switch device/switch fabric connectivity of the second switch device to the switch fabric that provides a switch device role for the second switch device by determining that the second switch device/switch fabric connectivity enables data communications that are available to the first switch device(s) that have the switch device role, verifies an operating configuration of the second switch device by determining that it matches an operating configuration of the primary switch device and, response to verifying the second switch device/switch fabric connectivity and the operating configuration of the second switch device, adds the second switch device to the switch fabric.
