Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If navigation apparatuses determine driving paths without considering weather information, then the path determination is simple and fast, but air conditioning power consumption increases
Solution Approach 1:
The navigation apparatus obtains weather information for each area in advance before determining the driving path. By having weather data ready beforehand for all possible route areas, the system can efficiently evaluate multiple paths without real-time delays, reducing air conditioning power consumption while maintaining simple and fast path determination
Solution Approach 2:
The system divides the map into multiple areas with different weather conditions and segments the driving path into path sections passing through these areas. This segmentation allows the navigation apparatus to evaluate weather conditions for each segment independently, optimizing air conditioning power consumption without overwhelming computational complexity
2Productivity
If the navigation apparatus calculates multiple path options with weather consideration, then the driving path optimization improves, but the calculation time increases
Solution Approach 1:
The navigation apparatus calculates driving times for path sections based on weather conditions but does not perform exhaustive calculations for every possible path variation. Instead, it performs partial calculations on representative path sections and uses these to determine the overall optimal path, improving optimization efficiency while limiting calculation time
Solution Approach 2:
The system changes the parameter basis for path evaluation from simple distance or time to include weather-condition-based air conditioning power consumption. By using weather information to adjust the evaluation parameters, the system achieves better path optimization without requiring exponentially more calculation time
3Loss of energy
If weather information is integrated into path determination, then air conditioning power consumption is reduced, but the system complexity increases
Solution Approach 1:
The navigation apparatus integrates weather information reception and processing into its existing path determination function, making the system multi-functional. The same controller that determines paths also evaluates weather conditions and calculates air conditioning power consumption, reducing the need for separate dedicated systems and minimizing overall system complexity
Solution Approach 2:
The system merges the weather information processing function with the map data and path determination functions. By combining these elements into a unified path evaluation process, the system reduces energy loss through integrated processing while avoiding the complexity of separate independent systems

AI summary
A navigation apparatus includes a receiver for receiving weather information for one or more areas, a map data storage in which map data is stored, and a controller for generating one or more path sections using the weather information for the one or more areas and for determining a driving path for consuming a minimum amount of air conditioning power using the weather information and the map data for each path section.
