Engineering Contradiction Analysis
1Productivity
If distributed data processing is performed across multiple nodes with varying attributes, then resource utilization and processing capacity are improved, but assignment complexity and management difficulty increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting node attributes and transform parameters based on current system state. The control unit modifies assignment decisions according to changing node capacities, workloads, and security requirements, allowing the system to optimize processing capacity while managing complexity through adaptive parameter adjustment rather than static complex scheduling rules
Solution Approach 2:
The patent segments the distributed system into independent nodes with specific attributes and transforms with specific requirements. By dividing the overall processing task into smaller units that can be independently assigned to nodes based on their attributes, the system improves processing capacity through parallel execution while managing assignment complexity through modular, attribute-based matching rather than holistic system management
2Productivity
If secure computation methods are assigned to nodes based on node attributes, then computation security and efficiency are improved, but assignment time and scheduling overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing node attributes that characterize their security capabilities and computational characteristics. These attributes are defined in advance, allowing the control unit to quickly match transforms to nodes without performing complex analysis during assignment. This pre-characterization enables efficient secure computation assignment while minimizing scheduling overhead
Solution Approach 2:
The patent implements feedback mechanisms where the control unit continuously monitors node performance, security state, and workload conditions. This feedback allows the system to dynamically adjust assignments based on current conditions, improving computation efficiency by assigning transforms to optimally suited nodes while reducing assignment time through learned patterns and real-time state awareness rather than exhaustive evaluation
