Solution Overview

Problem

The inefficiency in managing test cases for multimedia equipment leads to repeated testing of similar or duplicate cases, resulting in reduced test efficiency and increased costs due to manual classification based on user intuition and experience.

Innovation Solution

A test case management system that compares test cases using a similarity score calculation method, classifying and merging cases based on string similarity analysis to automate the classification process, thereby reducing redundant testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If test cases are managed manually based on user intuition and experience, then classification can be performed, but similar or duplicate cases are tested again leading to reduced test efficiency and increased costs

Engineering Contradiction:

Improvemanual classification operationVSAvoidtest efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical classification process with an automated string similarity comparison system. The controller automatically compares test case strings using similarity scoring algorithms, eliminating the need for manual user judgment and experience-based classification, thereby preventing duplicate tests and improving test efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables test case classification to serve itself through automated self-comparison and self-categorization. Test cases automatically compare themselves against existing cases in the database, calculate their own similarity scores, and determine their classification status without external human intervention

Inventive Principle:

Principle #25Self-service

2Quantity of substance

If manual management of test cases is performed, then test cases can be stored and accessed, but large amounts of time and costs are consumed

Engineering Contradiction:

Improvetest case management capacityVSAvoidtime and cost consumption

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent replaces time-consuming manual management operations with automated string comparison and similarity scoring mechanisms. The system automatically processes and classifies test cases using algorithmic approaches, dramatically reducing the time and computational resources required compared to manual handling

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transforms the qualitative, experience-based manual classification parameter into a quantitative string similarity score parameter. By converting classification from a subjective human judgment to an objective numerical comparison, the system enables efficient automated processing and reduces time consumption

Inventive Principle:

Principle #35Parameter changes

AI summary

A test case management system includes an input and output (I/O) interface for receiving a first test case, a database (DB) for storing a second test case, and a controller for comparing the first test case with the second test case based on a similarity score between a string of the first test case and a string of the second test case.
