Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If autonomous vehicles use traditional navigation displays to show current position and route, then the operator can see basic navigation information, but the operator cannot visualize the vehicle's future maneuvers and predicted path, leading to uncertainty and lack of control
Solution Approach 1:
The patent creates a virtual copy of the autonomous vehicle and its environment that replicates the real-world scenario. This virtual representation allows operators to view predicted maneuvers, alternate routes, and future vehicle positions without adding physical complexity to the actual vehicle system. The virtual model serves as an information bridge, showing what the vehicle will do without requiring complex physical display mechanisms.
Solution Approach 2:
The patent transitions from traditional 2D map displays to a 3D virtual reality environment that immerses the operator in the vehicle's predicted path and surrounding context. This dimensional enhancement provides comprehensive visualization of future maneuvers, alternate routes, and spatial relationships without proportionally increasing system complexity, as the additional dimension is achieved through computational rendering rather than physical expansion.
2Ease of operation
If the system displays detailed virtual reality information about future maneuvers and alternate routes, then operator confidence and control are enhanced, but the computational processing requirements and system complexity increase
Solution Approach 1:
The virtual reality system serves multiple functions simultaneously: it displays the predicted vehicle path, shows alternate routes, visualizes future maneuvers, and provides spatial context for decision-making. By consolidating these multiple information delivery functions into a single immersive interface, the system enhances operator control without proportionally increasing complexity, as the same computational infrastructure supports diverse visualization needs.
Solution Approach 2:
The virtual reality environment acts as an intermediary between the autonomous vehicle's navigation system and the operator. Rather than requiring the operator to interpret raw data from multiple sensors and processors, the VR system translates complex navigation information into an intuitive visual representation, easing the operator's interaction with the system while managing computational complexity through standardized rendering pipelines.
3Adaptability or versatility
If the autonomous vehicle allows real-time route adjustments by the operator, then the operator has greater control over the vehicle's path, but the system must continuously recalculate and redisplay maneuvers, increasing processing demands
Solution Approach 1:
The system pre-calculates multiple alternate routes and potential maneuvers before the operator needs to make a decision. By having these options prepared in advance and displayed in the virtual reality environment, the operator can review and select from pre-computed alternatives without triggering intensive real-time recalculations. This preliminary computation reduces energy consumption during actual route adjustment moments, as the heavy computational work was performed beforehand.

AI summary
The virtual reality navigation system can display the position of an autonomous vehicle at a predetermined amount of time in the future via virtual reality. A virtual reality display can display a virtual reality autonomous vehicle, as if the virtual reality autonomous vehicle is the autonomous vehicle operating at the predetermined amount of time in the future. Additionally, a virtual reality interface can provide an interface for an operator to interact with the environment of the autonomous vehicle. The virtual reality interface can receive an alternate route selection, and display in virtual reality the one or more maneuvers that would be required to reach the selection.
