Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital accelerator pedal systems are designed for specific vehicle models, then they can be optimized for that model, but they are not scalable and require complete modification for each vehicle upgrade
Solution Approach 1:
The patent designs the accelerator pedal system with universal adaptability through standardized digital communication interfaces (CAN bus, LIN bus, FlexRay) and a configurable control unit that can be programmed to work with different vehicle architectures. The modular design allows the same hardware platform to be adapted to various vehicle models without complete modification, achieving both optimization and scalability.
Solution Approach 2:
The control unit is designed to be dynamically configurable through software programming, allowing it to adapt to different vehicle models and communication protocols. This dynamic reconfigurability enables the system to maintain model-specific optimization while being scalable across different vehicle platforms.
2Ease of operation
If a complete dual throttle system is installed, then acceleration can be controlled from multiple locations, but the system takes up significant space under the dashboard
Solution Approach 1:
The patent merges the dual throttle control functions into a single integrated electronic system. Instead of requiring separate mechanical throttle bodies and linkages for each pedal, the system uses a single electronic control unit that receives input from either the original accelerator pedal or the additional pedal, eliminating the need for duplicate mechanical components and significantly reducing space requirements under the dashboard.
3Device complexity
If analog sensors are used in accelerator pedal systems, then the system can be simpler in design, but the signals are susceptible to wear and failure
Solution Approach 1:
The patent replaces mechanical contact-based analog sensors with non-contact digital sensors such as Hall effect sensors or magnetic sensors. These digital sensors have no moving parts or contact wear, providing reliable position detection throughout the system's operational life while maintaining relatively simple design through integration with the control unit.
