Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual design process is used for API adapter generation, then flexibility and control are maintained, but development time and labor costs increase significantly
Solution Approach 1:
The patent introduces a conversion rule calculation unit as an intermediary component that automatically generates conversion rules by performing schema matching between orchestrator data models and API specification data models. This intermediary automates the complex design process without requiring direct manual intervention, thereby increasing automation while managing system complexity through modular architecture
Solution Approach 2:
The API adapter generation process is segmented into distinct automated components: schema matching module, conversion rule calculation unit, and API adapter generation unit. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while achieving high-level automation of the generation process
2Productivity
If manual design and implementation processes are used, then quality control is possible, but the period for adding or modifying API adapters is extended
Solution Approach 1:
The system performs preliminary schema matching between orchestrator data models and API specification data models to pre-calculate conversion rules before actual API adapter generation is needed. This preliminary action enables rapid adapter generation and modification by having conversion logic prepared in advance, significantly reducing the time required for adding or modifying adapters
Solution Approach 2:
The patent uses template-based generation where conversion rules and adapter structures are copied and adapted from existing patterns. The generation unit creates new API adapters by copying and customizing templates based on the calculated conversion rules, enabling rapid reproduction of adapters without manual design, thus improving productivity while maintaining consistency
3Ease of manufacture
If automated generation is implemented, then cost and time are reduced, but the complexity of the generation system increases
Solution Approach 1:
The conversion rule calculation unit serves multiple functions: it performs schema matching, calculates conversion rules, and generates conversion logic that can be applied across different API adapters. This multi-functionality reduces the need for separate specialized components for each task, simplifying the overall system structure while maintaining automation and ease of adapter generation
