Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the management system transmits information to destination terminals without detecting communication status, then the transmission process is simple and fast, but connection failures occur due to terminal engagement with other terminals

Engineering Contradiction:
Improveconnection establishment reliabilityVSAvoidstatus management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The management system performs preliminary detection of communication status before transmitting information to destination terminals. The status detection unit checks whether destination terminals are engaged in other communications beforehand, preventing connection failures by avoiding transmission to busy terminals.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where destination terminals report their communication status back to the management system. The status detection unit continuously monitors and updates terminal engagement states, allowing the management system to make informed decisions about information transmission timing.

Inventive Principle:
Principle #23Feedback

2Reliability

If the management system detects communication status before transmission, then connection reliability improves, but the system complexity and detection time increase

Engineering Contradiction:
Improvesession management reliabilityVSAvoidstatus detection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The management system performs status detection in advance before information transmission is needed. By checking terminal availability beforehand, the system avoids last-minute detection delays and ensures reliable connection establishment without rushing the detection process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The status detection unit continuously monitors terminal communication states, maintaining an up-to-date view of terminal availability. This continuous monitoring eliminates the need for repeated discrete detection cycles, reducing overall detection time while maintaining reliability.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If multiple terminals communicate simultaneously without status management, then the system is simple to operate, but connection conflicts and communication failures occur

Engineering Contradiction:
Improvecommunication initiation efficiencyVSAvoidcommunication session reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Destination terminals provide feedback about their communication status to the management system. This feedback mechanism allows the system to coordinate multiple terminal communications effectively, preventing conflicts while maintaining high productivity in communication initiation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The management system performs preliminary status checks before allowing communication initiation between terminals. By detecting terminal availability in advance, the system enables efficient communication setup while preventing conflicts that would reduce both productivity and reliability.

Inventive Principle:
Principle #10Preliminary action
