Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional navigation systems use standard routing algorithms, then routes can be generated quickly, but the accuracy of route identification deteriorates when roadways overlap or are stacked at the same location
Solution Approach 1:
The patent introduces a vertical dimension (height parameter) to distinguish between overlapping or stacked roadways that share the same horizontal coordinates. By incorporating elevation data into the routing system, the patent enables differentiation between roadways at different levels (e.g., overpasses, underpasses, multi-level intersections), thereby resolving the ambiguity that causes incorrect route identification without requiring fundamentally new routing algorithms
Solution Approach 2:
The patent enhances the standard routing parameters by adding height/elevation as an additional dimension. The system collects and processes height data from multiple sources (GPS, barometric pressure, map data) to create a more comprehensive parameter set for route determination. This parameter enrichment allows the existing routing algorithms to accurately distinguish between stacked roadways while maintaining their computational efficiency
2Measurement precision
If the system collects and processes height data from multiple sources, then route accuracy improves, but data processing time and computational resources increase
Solution Approach 1:
The patent performs data aggregation and preliminary processing in advance by collecting height information from multiple sources (GPS, barometric pressure sensors, map data) and storing it in a pre-processed format. This preliminary action allows the system to have height data readily available when generating routes, eliminating the need for real-time computation of height parameters and reducing data processing time during actual route generation
Solution Approach 2:
The patent creates a multi-functional height data collection system that uses the same height parameter infrastructure for multiple purposes: distinguishing stacked roadways, calculating accurate distances between points on different levels, determining appropriate service providers, and assessing toll requirements. This universal approach consolidates data processing efforts and avoids redundant computations
3Measurement precision
If the system distinguishes between different levels of roadway, then routing accuracy improves, but the complexity of detecting and measuring roadway levels increases
Solution Approach 1:
The patent introduces height parameters as an intermediary element that mediates between the physical roadway levels and the digital routing representation. Instead of directly detecting and measuring complex three-dimensional roadway geometries, the system uses height data as a simplified intermediary that captures the essential vertical differentiation. This intermediary approach transforms a complex measurement problem into a manageable parameter comparison task

AI summary
Systems and methods for managing routing involving an indicated point of interest associated with a plurality of levels of a multilevel (overlapping or stacked) roadway are provided. In example embodiments, a networked system aggregates trip data received from user devices that includes location information and detected attributes for points of interest. The networked system analyzes the location information and the detected attributes to determine a height parameter and, in some cases, a characteristic associated with different levels of the multilevel roadway for points of interest. The height parameters and characteristics for each point of interest are stored to a database in a data storage. During runtime, the networked system receives a request that includes a point of interest. In response, the networked system detects a level of roadway at the point of interest using the database and real-time device data. Based on the detected level of the multilevel roadway, a route is generated and presented.
