Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional evaluation tools are used for cellular module communication performance metrics, then measurement precision can be maintained, but device portability and ease of operation deteriorate due to bulky size

Engineering Contradiction:

Improvecommunication performance metric evaluation accuracyVSAvoidfield deployment convenience

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The conventional bulky evaluation tool is segmented into a portable evaluation device and a cloud server. The portable device handles local data collection and preliminary processing, while the cloud server performs complex analysis and storage, enabling field deployment without sacrificing measurement precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A cloud server acts as an intermediary between the portable evaluation device and the final results. The portable device collects data in the field and transmits it to the cloud server for processing, allowing the device to remain simple and portable while maintaining high measurement precision through cloud-based analysis.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive communication performance metrics are monitored and stored locally, then measurement precision and data availability improve, but device complexity and storage requirements increase

Engineering Contradiction:

Improvecommunication performance metric evaluation accuracyVSAvoidstorage and processing requirements

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

Complex data processing, storage, and analysis functions are extracted from the portable evaluation device and relocated to the cloud server. The portable device only performs lightweight data collection and transmission, significantly reducing its complexity and storage requirements while maintaining comprehensive metric monitoring capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system transitions from a single-device local storage model to a distributed cloud-based storage model. By moving data to the cloud dimension, the portable device's storage and processing burden is dramatically reduced while comprehensive metric monitoring is maintained through cloud infrastructure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A portable device and method for determining communication performance metrics are provided. The portable device communicates with the cloud and includes a control device and storage. The control device records and/or processes communication-related data for determining the corresponding metric. The control device acquires communication-related data of a predetermined communication performance metric based on the configuration information, and determines and records the predetermined communication performance metric of the to-be-tested cellular module based on the communication-related data, or records the communication-related data; and uploads the predetermined communication performance metric or the communication-related data to the cloud via the to-be-tested cellular module when the data is required and able to be uploaded to the cloud. Storage stores the predetermined communication performance metric or the communication-related data when there is no need or inability to upload the data to the cloud and the storage space is not full.
