Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If collision warning systems are implemented in micromobility vehicles, then user safety is improved, but device complexity increases
Solution Approach 1:
The collision warning system is divided into separate functional modules: proximity sensors for detection, speed sensors for measurement, controllers for processing, and warning devices for alerting. This segmentation allows each component to be optimized independently while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The system performs preliminary detection and calculation of collision risk before a collision occurs. By continuously monitoring proximity and speed, the system calculates estimated time to collision in advance and activates warning devices proactively, enabling users to take preventive action before accidents happen.
2Reliability
If continuous collision monitoring is performed, then accident prevention is improved, but energy consumption increases
Solution Approach 1:
The system performs collision risk assessment at periodic intervals rather than continuously. The controller calculates estimated time to collision based on current proximity and speed measurements, then compares this with a threshold. This periodic monitoring approach maintains effective accident prevention while significantly reducing energy consumption compared to continuous real-time monitoring.
