1Adaptability or versatility

If manual configuration of steering stability settings is used for each RC model vehicle, then the system can be adapted to different vehicle parameters, but the complexity of operation and setup increases significantly

Engineering Contradiction:

Improveadaptability to different vehicle parametersVSAvoidease of setup and configuration

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically identifies the RC model vehicle and retrieves its parameters, then self-configures the steering stability settings without requiring manual input from the operator. The receiver unit autonomously downloads the appropriate settings from the controller based on vehicle identification, eliminating the need for manual configuration while maintaining adaptability to different vehicle types.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The steering stability settings are pre-calculated and stored in the controller based on different vehicle parameters before the vehicle operates. When the vehicle is identified, the corresponding pre-prepared settings are automatically retrieved and applied, avoiding the need for real-time manual configuration and enabling immediate optimal performance.

Inventive Principle:

2Ease of operation

If generic steering stability settings are used for all RC model vehicles, then the system is easier to operate, but the effectiveness of steering stabilization decreases due to varying vehicle dynamics

Engineering Contradiction:

Solution Approach 1:

The system changes the control parameters of the steering stability system based on the identified vehicle type and its specific parameters. Different gain values, filter settings, and control algorithm parameters are applied according to the vehicle's wheelbase, track width, weight distribution, and other dynamic characteristics, ensuring optimal performance for each vehicle configuration while maintaining automatic operation.

Inventive Principle:

Solution Approach 2:

The controller is designed with universal functionality to support multiple vehicle types by storing multiple sets of steering stability settings corresponding to different vehicle configurations. The system can automatically select and apply the appropriate settings for any connected RC model vehicle, making it universally applicable across different vehicle types without requiring manual intervention.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If vehicle-specific steering stability settings are manually configured, then the steering stabilization responds effectively to vehicle-specific disturbances, but the time required for system setup increases

Engineering Contradiction:

Improveeffectiveness of disturbance responseVSAvoidtime for system configuration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system automatically performs the time-consuming task of matching vehicle parameters with appropriate steering stability settings. The receiver unit self-identifies the vehicle type and autonomously downloads the correct settings from the controller, eliminating the manual configuration process and reducing setup time to merely connecting the vehicles, while still achieving vehicle-specific optimized performance.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

All possible vehicle parameter combinations and their corresponding optimal steering stability settings are pre-calculated and stored in the controller during manufacturing. When a vehicle connects to the system, the matching and configuration process occurs automatically in the background, saving the time that would otherwise be spent on manual analysis and configuration while ensuring optimal settings are applied.

AI summary

An electronic system for stabilizing steering of a model vehicle may use different settings depending upon the RC model vehicle to be controlled. Different vehicles have different dynamic operation and responses and therefore may require different Electronic Steering Stability (ESS) system "settings". The "settings" may be different "gains", or different "coefficients" used with the control system algorithms. "Settings" may also mean that a completely different control algorithm may be used. For example, a vehicle A may be controlled adequately with a "P" control algorithm, while a vehicle B may require a complete "PID" control algorithm to be implemented.
