Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alignment information is added to synchronize data reads, then data synchronization is improved, but storage capacity is reduced
Solution Approach 1:
The system performs preliminary calculation of zero phase start positions during the write operation or before reading. This pre-computation allows the read operation to directly use these pre-calculated positions for alignment, eliminating the need to store extensive alignment information on the media while maintaining synchronization capability.
Solution Approach 2:
The patent introduces an intermediary alignment circuit that receives partial alignment data from the storage medium and combines it with pre-calculated zero phase start information. This intermediary processing allows the system to use minimal stored alignment data effectively by supplementing it with computationally derived alignment references.
2Measurement precision
If full alignment data is stored with each fragment, then synchronization accuracy is improved, but format efficiency deteriorates
Solution Approach 1:
The system applies different alignment strategies to different parts of the data structure. Full alignment information is stored only with the first fragment, while subsequent fragments use a simplified alignment format combined with pre-calculated zero phase start positions. This local differentiation maintains synchronization accuracy where needed while improving overall format efficiency.
Solution Approach 2:
The patent changes the alignment data parameters from complete alignment information to condensed alignment markers combined with pre-computed phase references. By transforming the alignment data from a comprehensive format to a compact format supplemented by calculation, the system reduces storage overhead while preserving synchronization precision.
3Device complexity
If alignment circuits are simplified to reduce complexity, then device complexity is reduced, but alignment precision deteriorates
Solution Approach 1:
Complex alignment calculations are performed in advance and stored as pre-computed zero phase start positions. The alignment circuit during read operations only needs to retrieve and apply these pre-computed values, significantly reducing circuit complexity while maintaining alignment precision through the use of accurate pre-calculated references.
