Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the navigation system optimizes the driving route based on length and travel time, then the efficiency and time to reach destination are improved, but the driving pleasure is deteriorated
Solution Approach 1:
The patent introduces a fun index as a new parameter to evaluate driving routes, transforming the route optimization from purely efficiency-based (time and distance) to a multi-dimensional evaluation that includes driving pleasure. The fun index quantifies aspects like lateral accelerations, frontal accelerations, slope variations, decelerations, and urban section presence, allowing the system to balance efficiency with driving enjoyment through parameter expansion.
2Use of energy by moving object
If the navigation system provides the shortest path based on minimized cost function, then the energy consumption is reduced, but the driving experience and pleasure are deteriorated
Solution Approach 1:
The system expands the optimization criteria by incorporating the fun index alongside energy consumption and time parameters. This allows the navigation system to evaluate multiple competing objectives simultaneously, selecting routes that achieve an optimal balance between energy efficiency and driving pleasure rather than prioritizing energy savings alone.
Solution Approach 2:
The patent enables dynamic route selection by making the optimization criteria adaptable. The system can adjust the weightings of different parameters (energy, time, fun index) based on user preferences, vehicle characteristics, and route conditions, allowing the optimization strategy to change dynamically rather than following a fixed minimization approach.
3Productivity
If the navigation system focuses on optimized parameters like route length and travel time, then the calculation efficiency is improved, but the comprehensiveness of route evaluation is deteriorated
Solution Approach 1:
The patent segments the route evaluation into multiple independent components: traditional efficiency parameters (length, time, energy) and the fun index components (lateral accelerations, frontal accelerations, slope variations, decelerations, urban sections). Each segment can be calculated and optimized independently, then combined to form the overall route evaluation, maintaining calculation efficiency while achieving comprehensive assessment.

AI summary
A method to calculate a driving route includes the steps of acquiring information corresponding to a departure place of the motor vehicle and to a target destination, determining a road map comprising a departure point and an arrival point of the driving route associated with the departure place and with the destination, respectively, calculating the driving route on the road map from the departure point to the arrival point by solving a path planning problem comprising an optimization of a target function depending on at least one first scalar parameter defined by a fun index, wherein the fun index is indicative of a level of fun of the driving route and wherein the target function strays away from an optimum value thereof when the fun index indicates a deviation of the level of fun from a target level or a decrease in the level of fun, the optimum value of the target function corresponding to the solution of the path planning problem.
