Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional mechanical connection methods are used for brake and accelerator systems, then the structure is simple and reliable, but the vehicle space is wasted and maneuverability is poor
Solution Approach 1:
The patent replaces traditional mechanical connection systems (brake pedals, accelerator pedals with rigid linkages) with an electronic sensor-based system. Pressure-sensitive sensors detect driver input forces and convert them to electrical signals, eliminating the need for complex mechanical transmission components. This substitution frees up vehicle space while maintaining control functionality through electronic actuation means that can be positioned flexibly within the vehicle structure.
Solution Approach 2:
The patent creates a multi-functional operating apparatus where a single integrated system handles both brake and accelerator functions through different sensor positions and actuation modes. The electronic architecture allows the same basic structure to serve multiple driving operations (acceleration, braking, deceleration) by varying the sensor activation patterns, thereby improving space utilization without requiring separate dedicated mechanical systems for each function.
2Ease of operation
If rigid mechanical connections are used for operating apparatus, then the connection is stable and reliable, but the apparatus cannot be positioned flexibly and maneuverability is poor
Solution Approach 1:
The patent implements a dynamic positioning system where the operating apparatus can change its position and configuration based on driving conditions. The electronic sensor system detects driver intent and the actuating means adjust the apparatus position dynamically, allowing optimal maneuverability in different situations while maintaining connection stability through electronic control rather than rigid mechanical constraints.
Solution Approach 2:
The patent introduces electronic sensors and control systems as intermediary elements between the driver's input and the vehicle's response. This intermediary electronic layer replaces direct rigid mechanical connections, allowing flexible positioning of the operating apparatus while maintaining reliable signal transmission through electrical connections that can accommodate positional variations without compromising stability.
3Adaptability or versatility
If the operating apparatus is designed for gasoline car structure, then it meets existing safety standards, but it does not meet the evolving safety standards of new energy automobiles
Solution Approach 1:
The patent designs a universal operating apparatus that can adapt to both traditional gasoline vehicle architectures and new energy vehicle requirements. The electronic sensor and actuation system provides a platform that can be configured for different vehicle types and safety standards, allowing the same basic design to serve multiple applications including new energy automobiles with their evolving safety requirements while maintaining compliance through flexible electronic control.
Solution Approach 2:
The patent utilizes parameter changes in the electronic system to adapt to different safety standards and vehicle types. By adjusting sensor sensitivity, actuation force parameters, and control algorithms, the operating apparatus can meet different safety requirements without changing its fundamental structure, enabling compatibility with both traditional and new energy vehicle safety standards through software and parameter configuration rather than hardware redesign.
