Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a runtime environment is created based on settings of upper level application and lower level basic software, then communication between software components is supported, but much time and great efforts are required
Solution Approach 1:
The patent applies preliminary action by pre-defining template files that contain standardized runtime environment configurations. These templates are prepared in advance with common communication settings between software components, allowing the system to reuse them during code generation without requiring time-consuming manual configuration each time a runtime environment is created.
Solution Approach 2:
The patent uses copying by replicating proven runtime environment configurations from template files. Instead of creating new runtime environments from scratch, the system copies and adapts pre-established templates that already contain validated communication settings, significantly reducing the time and effort required while maintaining reliability.
2Ease of manufacture
If hardware is made dependent in software development process, then software can be developed with specific hardware integration, but integration of electronic device systems mounted on vehicle becomes difficult
Solution Approach 1:
The patent applies segmentation by separating hardware-dependent configurations from the core software development process. Configuration information about hardware is extracted into distinct template files, allowing the main software to remain hardware-agnostic while still supporting specific hardware integrations when needed. This segmentation enables easier system integration by allowing independent development and later combination of different hardware components.
Solution Approach 2:
The patent achieves universality by creating a standardized runtime environment generation system that can work with multiple types of hardware through common template interfaces. The extracted configuration information uses universal data structures and formats that can accommodate different hardware platforms, making the software development process adaptable to various electronic device systems while maintaining ease of manufacture.
3Device complexity
If operation time is not considered in RTE code generation, then code generation is simpler, but operation timing and stability of application software cannot be secured
Solution Approach 1:
The patent applies feedback by incorporating operation time information from a database into the RTE code generation process. The system queries the database for historical operation time data, uses this feedback to optimize code generation parameters, and generates configuration information that ensures timing requirements are met. This feedback loop maintains reliability while managing complexity through automated data-driven decisions.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting code generation parameters based on operation time requirements. The system extracts and analyzes operation time parameters from the database, then modifies generation settings to produce RTE code that meets timing constraints. This approach secures operation timing and stability by making the generation process adaptive to specific timing requirements rather than using fixed complex procedures.
