Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transceivers are added to simplify wiring and facilitate replacement, then ease of operation and ease of repair are improved, but reliability deteriorates due to potential loss of synchronization with safety standards
Solution Approach 1:
The system performs preliminary actions by establishing a resynchronization trigger mechanism and predefined resynchronization procedures before synchronization is lost. When the secondary wireless transceiver detects a trigger condition (such as network establishment or specific events), it automatically initiates resynchronization within a target time interval, preventing compliance issues before they occur.
Solution Approach 2:
The system implements feedback through the resynchronization trigger mechanism. The secondary wireless transceiver continuously monitors the wireless network status and provides feedback by detecting when resynchronization is needed. This feedback loop ensures that the system maintains synchronization compliance by automatically initiating resynchronization when triggers are detected, balancing the ease of wireless operation with reliability requirements.
2Device complexity
If wireless transceivers are used instead of wired connections, then device complexity is reduced, but reliability worsens due to increased probability of synchronization loss
Solution Approach 1:
The secondary wireless transceiver performs self-service by automatically detecting resynchronization triggers and initiating resynchronization procedures without external intervention. This self-service capability maintains synchronization compliance while preserving the simplicity of wireless connections, as the transceiver autonomously manages its own synchronization status.
Solution Approach 2:
The system prepares for potential synchronization issues by establishing predefined resynchronization triggers and procedures in advance. When triggers are detected, the secondary transceiver immediately executes resynchronization within the target time interval, preventing compliance violations before they occur.
3Reliability
If data transfers are performed within a target time interval to meet safety standards, then reliability is improved, but loss of time increases due to resynchronization requirements
Solution Approach 1:
The system applies partial action by performing resynchronization only when specific triggers are detected, rather than continuously. This selective approach ensures safety standard compliance by maintaining data transfers within the target time interval while minimizing unnecessary resynchronization operations, thereby reducing time loss while preserving reliability.
