Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access to passenger area is restricted during hazardous situations, then passenger safety is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically detecting hazardous situations through sensors and pre-establishing access restriction protocols. When a hazard is detected, the system proactively activates door locking mechanisms and access control systems before the situation escalates, ensuring passenger safety without requiring manual intervention during critical moments.
Solution Approach 2:
The system implements continuous feedback loops where sensors monitor the passenger area and vehicle conditions in real-time. This feedback information is processed by the control unit, which dynamically adjusts access restrictions based on the current safety situation, allowing the system to respond automatically to changing conditions while maintaining operational simplicity for passengers.
2Reliability
If access authorization verification is implemented, then unauthorized access is prevented, but device complexity increases
Solution Approach 1:
The access control system is designed with multi-functionality, where a single integrated system performs multiple tasks including door locking, access authorization verification, and hazard detection. This universal approach consolidates what would otherwise be separate systems into one cohesive unit, reducing overall device complexity while maintaining high reliability in access control.
Solution Approach 2:
The access control system operates autonomously by automatically verifying authorization credentials and enforcing access restrictions without requiring constant manual intervention. The system self-manages the verification process using integrated sensors and control algorithms, reducing the need for complex manual control mechanisms while ensuring reliable access management.
3Reliability
If door locking mechanisms are activated during hazardous situations, then passenger protection is improved, but ease of manufacture deteriorates
Solution Approach 1:
The door locking system is segmented into modular components including independent locking actuators, sensor modules, and control units that can be manufactured separately and then assembled. This segmentation allows for simplified manufacturing of individual components while maintaining the overall reliability of the integrated passenger protection system.
