Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a guidance system is implemented to detect danger zones and guide users, then driving safety is improved, but device complexity increases
Solution Approach 1:
The guidance system is divided into distinct functional modules: a sensor unit for capturing driving environment data, a detection unit for identifying danger zones, and a guide unit for providing navigation guidance. This segmentation allows each component to perform its specific function independently, improving overall system reliability while managing complexity through modular design.
Solution Approach 2:
The server acts as an intermediary between multiple mobility devices, centralizing the dangerous zone detection and guidance distribution functions. This intermediary approach allows individual mobility devices to remain relatively simple while still benefiting from comprehensive safety guidance provided by the centralized system.
2Measurement precision
If real-time video analysis is performed to detect danger zones, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The computationally intensive video analysis and danger zone detection functions are extracted from the mobility device itself and relocated to a external server. The sensor unit on the mobility device only needs to capture and transmit video data, while the energy-consuming processing operations are performed remotely, significantly reducing the energy burden on the moving object.
Solution Approach 2:
Instead of performing complex analysis on every frame locally, the system transmits video data to a server that creates processed copies (danger zone information) and sends back only the essential guidance information. This copying approach maintains high detection precision while minimizing the energy and computational resources needed on the mobility device.
3Reliability
If guidance is provided to all mobility users, then driving safety is improved, but loss of information increases due to false detections
Solution Approach 1:
The system implements feedback mechanisms where detection results are continuously refined based on accumulated data from multiple sources and time periods. The server analyzes patterns across multiple mobility devices and adjusts detection algorithms to reduce false positives, ensuring that guidance information becomes increasingly accurate and reliable over time.
Solution Approach 2:
The system performs preliminary verification of detected danger zones by cross-referencing with historical data, multiple sensor inputs, and predictive modeling before issuing guidance alerts. This preliminary action filters out potential false detections before they reach the user, maintaining high information quality and trustworthiness of the guidance system.

AI summary
An embodiment mobility guidance system includes a sensor provided in a mobility and configured to capture a driving video or an image to transmit the driving video or the image, a memory configured to store a danger zone image, a detector configured to compare the driving video or the image captured by the sensor with the danger zone image stored in the memory to detect an existence of a danger zone on a driving path of the mobility, and a guide configured to set a guide zone in response to the detector detecting the existence of the danger zone and a change in a speed or an acceleration of the mobility, and to provide the guide zone to a second mobility.
