Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual algorithms are replicated for sampling each voltage signal, then each voltage can be processed independently, but the code-base size increases and maintainability decreases
Solution Approach 1:
The patent implements a universal voltage management system where a single ADC module and algorithm can handle multiple voltage signals through configuration parameters. The system uses a unified processing framework that accepts different voltage inputs (VBAT, VPRE, VTEMP, etc.) and processes them through the same code path, eliminating the need for separate algorithms for each voltage signal while maintaining the ability to process them independently through configurable parameters.
2Adaptability or versatility
If separate algorithms are used for each voltage signal conversion, then customization is possible, but system complexity and code duplication increase
Solution Approach 1:
The patent employs parameter-based configuration to achieve customization without code duplication. Each voltage signal is characterized by parameters such as scaling factors, offset values, and destination addresses, which are stored in a configuration table. The unified algorithm reads these parameters and adjusts its behavior accordingly, allowing full customization of each voltage signal processing while using a single algorithm implementation.
3Reliability
If multiple individual conversion algorithms are implemented, then each voltage can be optimized separately, but the system becomes harder to maintain and update
Solution Approach 1:
The patent merges multiple individual conversion algorithms into a single unified voltage management algorithm. This unified algorithm processes all voltage signals through one code path, making the system easier to maintain and update. Any bug fixes, optimizations, or updates need to be made only once in the unified algorithm rather than replicating changes across multiple separate algorithms, while still maintaining the ability to process each voltage signal with its specific parameters for optimal accuracy.
