Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mode selection switch is installed to allow drivers to select driver modes, then the damping force can be controlled according to different driving conditions, but the vehicle installation space is required and the unit cost increases
Solution Approach 1:
The system automatically determines driver mode by analyzing driving behavior patterns from vehicle manipulation signals without requiring driver input through a mode selection switch. The driver tendency analysis unit processes acceleration, deceleration, and steering signals to calculate a driver tendency analysis value and automatically select the appropriate driver mode (soft, normal, or tough), making the system self-configuring based on observed driving patterns.
Solution Approach 2:
The patent replaces the mechanical mode selection switch with an electronic analysis system that processes vehicle manipulation signals. Instead of requiring physical switch operation, the system uses sensors and processors to detect driving behavior patterns and automatically adjust damping force through electronic control of the solenoid valve, eliminating the need for mechanical switching components.
2Adaptability or versatility
If a mode selection switch is installed to allow drivers to select driver modes, then the damping force can be controlled according to different driving conditions, but the vehicle cost increases
Solution Approach 1:
The driver tendency analysis unit utilizes existing vehicle manipulation signals (acceleration, deceleration, steering angle) that are already generated during normal vehicle operation. By analyzing these existing signals, the system performs driver behavior assessment without requiring additional dedicated sensors or hardware, thereby reducing manufacturing costs while achieving adaptive damping force control.
Solution Approach 2:
The system automatically determines driver mode by analyzing driving behavior patterns from vehicle manipulation signals without requiring driver input through a mode selection switch. The driver tendency analysis unit processes acceleration, deceleration, and steering signals to calculate a driver tendency analysis value and automatically select the appropriate driver mode (soft, normal, or tough), making the system self-configuring based on observed driving patterns.
3Adaptability or versatility
If existing electronic control suspension apparatuses are used with mode selection switch, then damping force can be adjusted, but the damping force according to prestored range may not meet individual driver's tendency
Solution Approach 1:
The system continuously monitors vehicle manipulation signals including acceleration manipulation signals, deceleration manipulation signals, and steering angle signals to calculate the driver tendency analysis value. This feedback mechanism tracks driving behavior patterns over time and adjusts the determined driver mode accordingly, ensuring the damping force matches the individual driver's evolving tendencies rather than being fixed to prestored ranges.
Solution Approach 2:
The patent transitions from static prestored damping force ranges to dynamic adaptive control. The driver tendency analysis value is continuously updated based on real-time vehicle manipulation signals, and the driver mode determination unit dynamically selects the appropriate mode (soft, normal, or tough) based on current driving behavior, allowing the damping force to adapt to changing driver tendencies during vehicle operation.
