Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery backup unit is used to supply energy during power events, then power availability is extended, but energy capacity is insufficient to support graceful shutdown of all applications
Solution Approach 1:
The system segments applications into different priority groups (high priority and low priority applications). During power events, the battery backup unit is allocated to support graceful shutdown of high priority applications first, while low priority applications are terminated when battery energy is depleted. This segmentation resolves the contradiction by distributing limited energy capacity across different application categories based on their shutdown requirements and business criticality.
2Reliability
If all applications are terminated gracefully during power events, then data integrity is maintained, but battery energy is depleted too quickly
Solution Approach 1:
The system applies different quality levels of shutdown service to different applications based on their priority classification. High priority applications receive full graceful shutdown service with sufficient battery power allocation to ensure data integrity, while low priority applications receive expedited termination when battery energy becomes insufficient. This local differentiation resolves the contradiction by ensuring data integrity for critical applications while extending overall battery duration through selective service quality.
3Duration of action of moving object
If battery backup unit extends energy availability, then application shutdown time is increased, but system complexity increases due to power management requirements
Solution Approach 1:
The system performs preliminary classification of applications into priority groups during normal operation, establishing a shutdown hierarchy before power events occur. This pre-established priority structure enables automated decision-making during power events, where the management controller can systematically terminate applications according to their pre-assigned priority levels without requiring complex real-time analysis. This preliminary action resolves the contradiction by providing structured extension of shutdown time while minimizing operational complexity through pre-planned termination sequences.
