Engineering Contradiction Analysis
1Ease of operation
If dockless mobility apparatuses are deployed in urban environments, then mobility convenience is improved, but safety incidents and injuries increase
Solution Approach 1:
The system performs preliminary obstacle detection using millimeter wave radar before the mobility apparatus reaches the obstacle. The computing module processes sensor data in advance to identify potential hazards, and the drive controller pre-adjusts acceleration and steering commands to prevent collisions, rather than reacting after contact occurs.
Solution Approach 2:
The system continuously receives feedback from the millimeter wave radar sensor about the environment ahead of the mobility apparatus. The computing module analyzes this feedback data to determine obstacle presence and characteristics, then the drive controller adjusts control commands based on this feedback loop, dynamically modifying acceleration and steering to maintain safety while preserving mobility convenience.
2Reliability
If millimeter wave radar and control systems are added to mobility apparatuses, then safety is improved, but device complexity increases
Solution Approach 1:
The millimeter wave radar sensor serves multiple functions: detecting obstacle presence, determining obstacle location, identifying obstacle type, and measuring obstacle trajectory. The computing module and drive controller work together as an integrated control system that handles multiple safety functions through a unified architecture, reducing overall system complexity despite the added capabilities.
Solution Approach 2:
The system replaces complex mechanical safety systems with electronic and software-based solutions. Instead of mechanical sensors and physical control mechanisms, the patent uses millimeter wave radar for detection and electronic control algorithms for safety decisions, simplifying the physical structure while maintaining or enhancing safety performance.
