Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If comprehensive vulnerability assessment is performed on all computer applications, then the completeness of security testing is improved, but the time required for remediation prioritization increases

Engineering Contradiction:

Improvecompleteness of security testingVSAvoidtime required for remediation prioritization

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system segments the vulnerability assessment process by classifying vulnerabilities into different categories (e.g., critical, high, medium, low severity) and prioritizing remediation based on exploitability levels. This allows comprehensive assessment of all applications while reducing the time needed for prioritization through automated classification and ranking mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary classification of vulnerabilities into severity categories and exploitability levels before final remediation prioritization. By pre-processing the assessment data to determine exploitability levels and categorize vulnerabilities, the system reduces the time required for subsequent remediation prioritization decisions.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If detailed vulnerability analysis is conducted on all applications, then the accuracy of risk assessment is improved, but the complexity of the analysis process increases

Engineering Contradiction:

Improveaccuracy of risk assessmentVSAvoidcomplexity of analysis process

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies different analysis depths and classification criteria to different vulnerability types and applications based on their local characteristics. Critical vulnerabilities in high-value applications receive more detailed analysis, while less critical vulnerabilities undergo streamlined assessment, maintaining accuracy where needed while reducing overall process complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system changes the parameters of vulnerability assessment based on the context, such as adjusting severity thresholds and exploitability criteria for different application types. This allows accurate risk assessment for critical systems while simplifying the analysis process for less critical applications.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If remediation prioritization is delayed, then the completeness of vulnerability remediation is improved, but the risk of ransomware attacks increases

Engineering Contradiction:

Improvecompleteness of vulnerability remediationVSAvoidrisk of ransomware attacks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary prioritization of vulnerabilities based on exploitability levels and severity classifications, enabling timely remediation actions before ransomware attacks occur. By pre-ranking vulnerabilities and identifying the most critical ones first, the system maintains both completeness of remediation and reduced risk exposure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback loops that continuously monitor vulnerability remediation progress and adjust prioritization lists accordingly. This ensures that remediation completeness is maintained while enabling timely response to emerging threats, as the feedback mechanism allows dynamic re-prioritization based on current risk conditions.
