Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors, actuators, control units, and electronic systems are implemented to support various vehicle functions, then the vehicle functionality and versatility are improved, but the device complexity and difficulty of detecting vehicle usage increase
Solution Approach 1:
The patent segments the vehicle's electrical system into multiple energy paths, each with unique identifiers. Each energy path represents a distinct route from the electrical system to energy consumers, allowing the complex system to be broken down into manageable, traceable segments. This segmentation enables detailed tracking of energy flow without requiring complex monitoring of every individual component interaction.
Solution Approach 2:
The patent introduces usage data as an intermediary element that mediates between the complex vehicle systems and the evaluation process. This usage data contains identifiers of energy paths and energy consumers, serving as a simplified representation that captures essential information about system usage without requiring direct analysis of the complex underlying systems.
2Measurement precision
If detailed monitoring of each energy path and energy consumer is implemented, then the measurement precision of vehicle usage detection is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent extracts only the essential identification information (energy path identifiers and energy consumer identifiers) from the complex system state, creating simplified usage data. This extraction approach captures the necessary information for precise usage detection while avoiding the complexity of monitoring and processing complete system states of all components.
Solution Approach 2:
The patent performs preliminary identification and labeling of energy paths and energy consumers with unique identifiers before usage detection is needed. This preliminary action establishes a structured framework that enables precise tracking without requiring complex real-time analysis during actual usage detection, as the identification structure is already in place.
Data Source
AI summary
A method detects a vehicle function of a vehicle having a plurality of energy paths and a plurality of energy consumers. Each energy path contains at least one energy consumer. In response to an active state of the vehicle function in the vehicle, usage data of the vehicle function is generated. The usage data include an identifier of the vehicle function, an identifier associated with the vehicle function of at least one energy path of the plurality of energy paths and an identifier associated with the vehicle function of at least a first energy consumer of the plurality of energy consumers. The the usage data are indicative of an energy path that is active based on the active state of the vehicle function for the provision of electrical energy to the first energy consumer. The method also includes transmitting of the usage data from the vehicle to a server.
