Engineering Contradiction Analysis
1Use of energy by moving object
If data transmission is performed using a fixed number of slices regardless of operation type, then transmission reliability is maintained, but power consumption increases unnecessarily
Solution Approach 1:
The patent implements dynamic slice selection where the number of active slices is adjusted based on operation type. The system transitions from static configuration to dynamic adaptation, enabling the transmission circuit to use only the necessary number of slices for each operation, thereby reducing power consumption while maintaining reliability through verification mechanisms
Solution Approach 2:
The system changes the operational parameter (number of active slices) based on different operation types. By modifying this parameter dynamically according to data verification results and operation requirements, the system achieves optimal power efficiency without compromising transmission reliability
2Productivity
If the number of slices is increased to improve transmission speed, then data transmission performance is enhanced, but power consumption increases
Solution Approach 1:
The system applies partial action by activating only the necessary number of slices required for each operation type rather than using all available slices. This selective activation achieves sufficient transmission performance for each operation while avoiding the power consumption that would result from using excessive slices
Solution Approach 2:
The system dynamically adjusts the number of active slices based on operation type and verification results, enabling the transmission circuit to optimize between speed and power consumption by using more slices only when necessary and fewer slices when sufficient
3Reliability
If all transmission circuits are activated for every operation, then transmission reliability is ensured, but unnecessary power is consumed
Solution Approach 1:
The system applies local quality by activating only the specific slices needed for each operation type rather than uniformly activating all slices. This localized activation ensures reliability for each operation while avoiding power wastage in unnecessary circuits
Solution Approach 2:
The system uses feedback from data verification to determine whether to activate additional slices. When verification succeeds, the system maintains current slice activation (avoiding power wastage). When verification fails, the system activates additional slices to ensure reliability, creating a feedback-driven power management mechanism
