Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If sampling parameters are transmitted individually without buffering, then communication overhead is reduced, but response duration for fault locating increases

Engineering Contradiction:

Improveresponse durationVSAvoidinteraction quantity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The sampling unit continuously samples and the module central processing unit stores sampling parameters in the sampling information storage unit before fault occurrence. When a fault occurs, the pre-stored sampling parameters are immediately available for transmission, eliminating the need to wait for individual parameter generation and reducing response duration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The N sampling parameters are grouped into multiple data blocks for transmission. This segmentation allows bulk transmission of pre-stored parameters, reducing the number of interaction cycles between optical module and network device while maintaining comprehensive fault analysis capability.

Inventive Principle:

Principle #1Segmentation

2Productivity

If sampling parameters are buffered and grouped into data blocks, then response duration is reduced, but communication overhead increases

Engineering Contradiction:

Improvefault locating speedVSAvoidcommunication overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

Sampling parameters are pre-buffered in the sampling information storage unit before fault occurrence. This allows the system to transmit multiple parameters in bulk after fault detection, improving fault locating speed while the buffering mechanism efficiently manages the data volume to control communication overhead.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If millisecond-level sampling is performed, then measurement precision is improved, but use of energy increases

Engineering Contradiction:

Improvesampling precisionVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The sampling unit performs sampling at millisecond intervals rather than continuously. This periodic sampling maintains sufficient measurement precision for fault detection while significantly reducing energy consumption compared to continuous sampling, as the system only activates the sampling and transmission functions when needed.

Inventive Principle:

Principle #19Periodic action

AI summary

A data processing method includes a module central processor obtaining sampling parameters from a sampler, and storing the sampling parameters into a sampling information storage circuit. When receiving an indication from a network device, the module central processor feeds back, to the network device, N sampling parameters that have been stored in the sampling information storage circuit, and sends the N sampling parameters through a plurality of data blocks.
