Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional simulators use motion components with fixed mass, then the structure is stable, but the simulation of highly dynamic driving maneuvers is limited
Solution Approach 1:
The patent implements a self-propelled simulator with variable mass capability through modular wheel assemblies that can be configured differently. The system uses multiple wheel assemblies (at least three, preferably four) that can be independently controlled, allowing the simulator to adapt its dynamic characteristics during operation. This enables simulation of highly dynamic maneuvers by adjusting the distribution and configuration of mass during the simulation process, rather than being constrained by fixed mass characteristics.
2Adaptability or versatility
If conventional simulators are installed on specific surfaces, then the operation is stable, but the area of application is limited
Solution Approach 1:
The patent creates a universal simulator platform that can operate on various surfaces (asphalt, concrete, plastic coverings, etc.) by using self-propelled wheel assemblies with adaptive suspension systems. The wheel assemblies are designed to accommodate different surface conditions through adjustable suspension characteristics and robust wheel designs. This multi-functional capability allows the simulator to be deployed in diverse locations without requiring specialized installation surfaces, thereby expanding the area of application while maintaining operational stability.
3Adaptability or versatility
If the simulator uses a self-propelled design with multiple wheel assemblies, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent divides the simulator into modular wheel assemblies, where each assembly functions as an independent unit with its own drive and suspension components. This segmentation allows for simplified design and control of individual modules while achieving complex overall behavior through their coordinated operation. The modular structure makes the system more manageable despite the increased number of components, as each module can be designed, tested, and maintained independently.
