Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If map data is stored without sorting by logical information, then storage operation is simpler and faster, but data retrieval efficiency deteriorates
Solution Approach 1:
The patent divides map data into multiple map segments, each corresponding to a specific memory block. This segmentation allows the system to organize and manage map data more efficiently by logical information, improving retrieval speed without overwhelming the system with a single large mapping operation.
Solution Approach 2:
The patent performs preliminary sorting of map segments by logical information during the data storage process. By organizing map data in advance according to logical addresses before actual data retrieval operations, the system optimizes future access patterns without compromising the simplicity of the storage operation itself.
2Productivity
If map data is divided and sorted across multiple memory blocks, then data processing efficiency is improved, but the complexity of mapping operations increases
Solution Approach 1:
The patent segments map data into multiple map segments that can be distributed across different memory blocks. This segmentation enables parallel processing and more efficient utilization of memory resources, improving overall data processing efficiency while maintaining manageable complexity through structured organization.
Solution Approach 2:
The patent introduces an additional organizational dimension by sorting map segments not only by their association with memory blocks but also by logical information. This multi-dimensional organization allows the system to optimize data processing efficiency across multiple criteria without proportionally increasing operational complexity.
3Productivity
If all map data is stored in a single memory block, then mapping operations are simpler, but memory device use efficiency deteriorates
Solution Approach 1:
The patent divides map data into multiple map segments that are distributed across different memory blocks. This segmentation enables more efficient utilization of the memory device by spreading the mapping load across multiple blocks, thereby improving overall memory device use efficiency while maintaining manageable complexity through structured organization.
Solution Approach 2:
The patent creates a universal mapping structure where map segments can be flexibly distributed across multiple memory blocks based on logical information. This multi-functional approach allows the mapping system to efficiently utilize any available memory block, improving overall device efficiency without significantly increasing operational complexity.
