Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the remaining driving distance is calculated and displayed based on remaining battery energy, then the driving distance information is provided to occupants, but the displayed driving distance may suddenly decrease without additional information or notification causing occupant anxiety
Solution Approach 1:
The notification device provides feedback to occupants about the reasons for driving distance reduction by detecting energy consumption patterns and notifying them of factors such as heating/cooling usage, uphill driving, or rapid acceleration. This feedback loop prevents information loss and maintains perceived reliability by explaining changes in remaining driving distance.
Solution Approach 2:
The notification device acts as an intermediary between the battery controller/driving controller and the occupants. It translates complex energy consumption data into understandable notifications about driving distance reduction causes, bridging the information gap between system calculations and user comprehension.
2Measurement precision
If detailed monitoring of battery state information is implemented to calculate remaining energy accurately, then energy consumption can be tracked precisely, but the device complexity increases
Solution Approach 1:
The battery controller and driving controller perform multiple functions: they monitor battery state information (state of charge, state of health, state of power), calculate remaining energy, detect excessive energy consumption, identify fuel efficiency deterioration sections, and trigger notifications. This multi-functionality reduces the need for separate dedicated components, managing complexity while maintaining measurement precision.
3Reliability
If real-time notification of energy consumption patterns is provided to occupants, then occupant anxiety is reduced, but the device complexity and energy usage increase
Solution Approach 1:
The notification system leverages existing controller resources (battery controller and driving controller) that are already performing calculations for other purposes. These controllers self-serve by using their computational capabilities to detect energy consumption patterns and generate notifications without requiring a completely separate dedicated notification system, thus reducing overall device complexity.
