Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional static drivetrain controls are used, then the system is simple and reliable, but precise control of vehicle dynamics is limited
Solution Approach 1:
The patent implements dynamic control of drivetrain parameters by allowing real-time adjustment of power distribution between front and rear wheels, throttle response characteristics, and brake force allocation. The system transitions from static preset modes to continuously adjustable dynamic parameters controlled by user input devices, enabling precise manipulation of vehicle dynamics during operation.
Solution Approach 2:
The control system integrates multiple functions into a unified platform that manages power distribution, throttle control, brake force allocation, and drivetrain parameter adjustment through common user input devices. This multi-functional approach allows a single system to perform what previously required multiple separate controls and adjustments.
2Adaptability or versatility
If preset drive modes are used, then ease of operation is improved, but adaptability to specific driving conditions is limited
Solution Approach 1:
The system replaces static preset modes with dynamic, continuously adjustable parameters. Users can modify power distribution ratios, throttle response curves, and brake force allocation in real-time based on specific driving conditions and preferences, rather than being constrained to fixed mode selections.
Solution Approach 2:
The patent implements continuous adjustment of key drivetrain parameters including power distribution between axles, throttle response characteristics, and brake force allocation ratios. These parameter changes enable the system to adapt to varying driving conditions and user preferences while maintaining ease of operation through intuitive input devices.
3Reliability
If real-time dynamic control is implemented, then vehicle performance and handling are improved, but device complexity increases
Solution Approach 1:
The system incorporates feedback mechanisms that continuously monitor vehicle state parameters and adjust drivetrain control accordingly. This feedback loop ensures reliable and predictable vehicle behavior during dynamic control operations, maintaining stability while enabling enhanced performance capabilities.
Solution Approach 2:
The patent introduces intermediary control elements including user input devices, computing systems, and control algorithms that mediate between driver intent and actual drivetrain actuation. These intermediaries manage the complexity of real-time dynamic control while presenting a simplified interface to the user, ensuring reliable control execution.
