Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImproveIndependent voltage signal processingVSAvoidCode-base size and maintainability
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate algorithms are used for each voltage signal conversion, then customization is possible, but system complexity and code duplication increase

Engineering Contradiction:
ImproveVoltage signal customizationVSAvoidAlgorithm duplication
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If multiple individual conversion algorithms are implemented, then each voltage can be optimized separately, but the system becomes harder to maintain and update

Engineering Contradiction:
ImproveVoltage conversion accuracyVSAvoidSystem maintainability
Core Design Contradiction:
ReliabilityVSEase of repair

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.

Inventive Principle:
Principle #5Merging (Combining)
