Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new roadside devices are installed to perform real-time processing, then real-time generation and distribution of driving assistance information is achieved, but capital investment increases
Solution Approach 1:
The patent enables existing roadside devices, originally designed for basic traffic information distribution, to perform advanced real-time processing functions by integrating edge server capabilities. This multi-functional approach allows single devices to handle both traditional traffic information tasks and new real-time driving assistance information generation, eliminating the need for separate new device installations and reducing capital investment while maintaining high productivity.
2Quantity of substance
If existing roadside devices are utilized, then capital investment is reduced, but real-time processing capability may be insufficient
Solution Approach 1:
The patent transforms existing roadside devices into real-time processing capable systems by changing their functional parameters through edge server integration. The devices transition from basic information distribution to advanced real-time processing by incorporating computational resources, data processing algorithms, and communication protocols that enable driving assistance information generation, thus maintaining low capital investment while achieving high real-time processing capability.
3Productivity
If roadside devices are equipped with edge-server processing units, then real-time processing is enabled, but device complexity increases
Solution Approach 1:
The patent merges edge server processing units with existing roadside devices into a unified system. Rather than adding separate complex systems, the edge server functionality is integrated directly into the roadside device architecture, combining computational resources, communication interfaces, and processing units into a single coordinated system. This merging approach enables real-time processing while managing device complexity through unified design and shared resources.
