Solution Overview

Problem

Conventional computing system verification processes are inefficient and costly due to the need for manual verification of multiple components, limited manpower, and the difficulty in simulating real-world scenarios, leading to inadequate testing of new systems.

Innovation Solution

A virtual device system that captures and stores transaction history between legacy and linked devices, allowing for the generation of test data to simulate interactions and verify the new computing system's responses, thereby reducing the need for extensive manual testing and minimizing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual verification is performed by developers or testers for each test case, then verification thoroughness can be improved, but verification time and cost increase significantly

Engineering Contradiction:

Improveverification thoroughnessVSAvoidverification time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent creates virtual copies of real transaction data through virtual devices that simulate legacy systems. These virtual devices reproduce actual transaction scenarios without requiring manual intervention for each test case, enabling automated verification that maintains thoroughness while reducing time consumption

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The verification system performs self-service by automatically executing test cases using virtual devices that generate and process test data without human intervention. The system autonomously verifies computing system responses across multiple scenarios, eliminating the need for manual verification while maintaining comprehensive coverage

Inventive Principle:

Principle #25Self-service

2Reliability

If multiple separate components are verified manually by multiple users, then component verification completeness can be improved, but resource consumption and cost increase

Engineering Contradiction:

Improvecomponent verification completenessVSAvoidresource efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent merges multiple verification tasks into a single integrated automated system. Virtual devices consolidate the functionality of multiple testers verifying different components, allowing comprehensive component verification to be performed by one system rather than requiring multiple manual operators

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The virtual device system performs multiple verification functions simultaneously - it can verify different components, simulate various legacy systems, and execute diverse test cases through a single multi-functional platform, improving resource efficiency while maintaining verification completeness

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If test environments are created for different legacy systems to verify outbound testing, then testing accuracy can be improved, but system complexity and setup cost increase

Engineering Contradiction:

Improvetesting accuracyVSAvoidtest environment complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces virtual devices as intermediary components that simulate legacy systems without requiring actual legacy system environments. These virtual intermediaries provide accurate transaction scenario reproduction while eliminating the need to set up and maintain complex test environments for each legacy system

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of creating physical test environments for different legacy systems, the patent creates virtual copies through software-based virtual devices. These copies reproduce the essential characteristics and transaction behaviors of legacy systems, maintaining testing accuracy while dramatically reducing environment setup complexity

Inventive Principle:

Principle #26Copying

4Measurement precision

If conversion programs are developed for each verification task, then task-specific verification accuracy can be improved, but development time and cost increase

Engineering Contradiction:

Improvetask-specific verification accuracyVSAvoidverification system development ease

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The virtual device system provides a universal verification platform that handles multiple verification tasks through a single system. Rather than requiring separate conversion programs for each task, the virtual devices can adapt to different verification scenarios through configuration rather than custom program development, improving ease of implementation while maintaining task-specific accuracy

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A virtual device acquires a transaction history between a legacy computing device and a linked device; obtains a first request provided from the legacy computing device based on the transaction history and a first response received from the linked device in response to the first request; receives a second request corresponding to the first request from a new computing device and determines a second response to the second request; and provides test information for the new computing device based on a comparison of the first response and the second response.
