Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current technologies are used for route modification, then system simplicity is maintained, but the ability to quickly and dynamically modify transportation routes in response to unforeseen events is insufficient
Solution Approach 1:
The patent segments the transportation network into discrete graph components (nodes representing locations, edges representing routes) to enable modular and efficient computation of alternate paths. This segmentation allows the system to quickly recalculate routes by focusing only on affected graph portions when unforeseen events occur, rather than reprocessing entire transportation networks.
Solution Approach 2:
The patent introduces a path graph as an intermediary data structure that connects optimal path nodes and facilitates efficient alternate path generation. This intermediary representation enables the system to quickly explore alternative routes by traversing the path graph structure, improving adaptability without proportionally increasing system complexity.
2Productivity
If traditional route modification methods are used, then computational resources are conserved, but the speed and efficiency of generating alternate routes during unforeseen events is insufficient
Solution Approach 1:
The patent performs preliminary actions by pre-computing and storing the optimal path graph structure, including all optimal path nodes and their connections, before unforeseen events occur. This preliminary preparation enables the system to rapidly generate alternate routes by querying the pre-computed graph structure rather than performing exhaustive searches when events happen, thus improving productivity while managing computational resource consumption.
Solution Approach 2:
The patent implements dynamic route generation by allowing the path graph to be efficiently traversed and modified based on real-time conditions. The system dynamically identifies alternate paths by exploring the pre-computed graph structure and calculating detour costs, enabling fast adaptation to changing conditions without requiring complete recalculation of the entire transportation network.
3Reliability
If comprehensive alternate path analysis is performed, then route reliability is improved, but computational time and complexity increase
Solution Approach 1:
The patent applies partial action by generating a limited set of meaningful alternate paths based on the path graph structure rather than exhaustively analyzing all possible routes. The system identifies alternate paths that deviate from the optimal path at specific nodes and evaluates their detour costs, providing sufficient reliability improvement without the computational burden of complete path enumeration.
Solution Approach 2:
The patent changes the parameter representation by using detour cost as a key metric to evaluate and rank alternate paths. By transforming the route evaluation problem into a detour cost calculation based on the pre-computed path graph, the system efficiently compares alternate routes and provides reliable recommendations without extensive computational time.
