Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If diagnostic flowcharts are manually created and statically maintained, then the initial diagnostic capability is established, but the system cannot adapt to improve based on actual usage feedback

Engineering Contradiction:
Improveadaptability of diagnostic flowchartsVSAvoidfeedback data from technicians
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback loops where diagnostic data collected from vehicle diagnostics is fed back to automatically update and refine diagnostic flowcharts. This continuous feedback mechanism allows the flowcharts to adapt and improve based on real-world diagnostic outcomes, resolving the contradiction between static maintenance and adaptability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The diagnostic system performs self-updating through automated analysis of collected diagnostic data. The system autonomously refines flowcharts based on patterns observed in actual diagnostic cases, eliminating the need for manual updates while continuously improving diagnostic accuracy and adaptability.

Inventive Principle:
Principle #25Self-service

2Reliability

If diagnostic flowcharts are frequently updated based on feedback, then diagnostic accuracy improves, but system complexity increases

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces manual flowchart updating mechanisms with automated computational processes. Algorithms automatically analyze diagnostic data, identify patterns, and generate flowchart updates, substituting complex manual procedures with streamlined automated systems that improve accuracy without proportionally increasing complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system dynamically adjusts diagnostic parameters and flowchart structures based on analyzed feedback data. By automatically modifying flowchart parameters such as decision nodes, diagnostic paths, and evaluation criteria, the system improves diagnostic accuracy while the automation manages complexity.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If comprehensive feedback data is collected from all diagnostic operations, then flowchart optimization improves, but data processing requirements increase

Engineering Contradiction:
Improveflowchart optimization efficiencyVSAvoiddata processing resources
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system extracts only the most relevant and actionable feedback data from comprehensive diagnostic operations for flowchart optimization. By filtering and selecting critical data points rather than processing all collected data, the system improves optimization efficiency while reducing unnecessary data processing overhead.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements selective feedback collection and processing, focusing on specific diagnostic scenarios and outcomes that have the greatest impact on flowchart optimization. This partial action approach processes sufficient data to achieve meaningful optimization without the excessive resource consumption of analyzing every possible data point.

Inventive Principle:
Principle #16Partial or excessive action
