Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specialized vehicle with measurement device is constructed, then measurement accuracy is improved, but cost increases
Solution Approach 1:
The patent applies universality by enabling ordinary vehicles to perform road measurement functions in addition to their primary transportation function. The measurement device is integrated into vehicles that already exist in the fleet, allowing them to serve dual purposes: transportation and road structure measurement. This eliminates the need for specialized measurement vehicles while maintaining measurement capabilities.
Solution Approach 2:
The system applies self-service by utilizing the vehicles' own detection units and existing operational routes to collect measurement data. The vehicles measure road structures during their normal service operations without requiring separate dedicated measurement missions or specialized equipment, thereby reducing costs while maintaining measurement functionality.
2Loss of information
If periodic vehicle measurement is implemented, then road structure data is obtained, but labor requirements increase
Solution Approach 1:
The patent implements continuity of useful action by collecting measurement data continuously during vehicle operations rather than through periodic dedicated measurement campaigns. The detection units continuously capture road structure information as vehicles traverse the road network during normal service, eliminating the need for periodic labor-intensive measurement interventions.
Solution Approach 2:
The system applies self-service by automatically collecting measurement data during vehicle operations without requiring human intervention for data collection. The detection units autonomously capture road structure information, and the server automatically processes and stores the data, eliminating manual labor requirements for measurement activities.
3Area of stationary object
If multiple vehicles collect data, then measurement coverage is improved, but data processing complexity increases
Solution Approach 1:
The patent applies merging by consolidating measurement data from multiple vehicles into a unified database on the server. The server integrates detection values from various vehicles, combines multiple data sets, and processes them collectively to extract comprehensive road structure information, thereby managing complexity through centralized data convergence.
Solution Approach 2:
The server acts as an intermediary that receives, standardizes, and processes data from multiple vehicles. It serves as a central mediator that harmonizes data from different sources, applies consistent processing algorithms, and generates unified road structure assessments, thereby simplifying the complexity of handling multi-vehicle data through a centralized coordination point.
