Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed service execution sequence is used, then the scheduling process is simple, but the flexibility of service scheduling deteriorates
Solution Approach 1:
The patent implements dynamic service execution sequences by allowing the scheduler to adjust the order of service execution based on real-time conditions. The execution sequence is no longer fixed but can be dynamically modified to adapt to different service requirements and system states, thereby improving flexibility while maintaining manageable complexity through automated scheduling logic.
Solution Approach 2:
The patent changes the parameter of execution sequence from a fixed value to a dynamically adjustable parameter. By allowing the sequence parameter to vary based on service priorities, resource availability, and system conditions, the system achieves greater flexibility without proportionally increasing complexity, as the changes are managed through structured scheduling mechanisms.
2Ease of operation
If each service separately invokes processing modules, then service independence is maintained, but repeated processing of the same modules occurs, affecting efficiency
Solution Approach 1:
The patent merges the invocation of processing modules at the scheduler level rather than allowing each service to independently invoke them. The scheduler consolidates module invocation requests from multiple services, ensuring that each processing module is called only once even when multiple services require its functionality. This maintains service independence in terms of logical execution while eliminating redundant processing through centralized coordination.
Solution Approach 2:
The scheduler serves as a universal coordination mechanism that handles invocation for multiple services simultaneously. It provides multi-functional capability by managing different service requirements through a unified interface, allowing the same processing module to be shared across multiple services without repeated execution, thereby improving overall system efficiency while preserving service autonomy.
3Reliability
If processing modules are invoked multiple times for different services, then each service gets its required processing, but the same modules are processed repeatedly, increasing execution time
Solution Approach 1:
The scheduler performs preliminary analysis of service requirements before execution begins. It identifies which processing modules are needed by which services and pre-plans the execution sequence to avoid redundant processing. By preparing the invocation plan in advance, the system ensures that each module is executed only once while still meeting all service requirements, thereby reducing execution time without compromising processing completeness.
Solution Approach 2:
The system implements feedback mechanisms where the scheduler monitors which processing modules have been executed and uses this information to prevent repeated invocation. After a module is executed, the scheduler receives feedback about its completion status and adjusts subsequent service execution accordingly, ensuring that services wait appropriately for module results rather than triggering redundant processing, thus reducing overall execution time while maintaining reliability.
