Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple electrical ignition system with remote control is used, then the device complexity is reduced, but the reliability and safety against accidental launches deteriorates
Solution Approach 1:
The system performs preliminary safety checks before allowing launch, including verifying the rocket is properly loaded, checking for presence of safety key, confirming user authentication, and ensuring the launch pad is in safe proximity. These preliminary actions prevent accidental launches by ensuring all safety conditions are met before ignition can occur.
Solution Approach 2:
A mobile device serves as an intermediary between the user and the launch pad, providing a user interface for authentication and control. The mobile device communicates with the launch pad via Bluetooth, adding a layer of controlled interaction that prevents direct or accidental activation while maintaining user control over the launch process.
2Device complexity
If traditional launch control without tracking is used, then the device complexity is reduced, but the ability to track and recover rockets deteriorates
Solution Approach 1:
The system continuously monitors launch parameters and transmits data back to the mobile device and cloud server. Feedback mechanisms include real-time tracking of rocket position, altitude, and launch status, allowing the system to provide updates and control adjustments based on actual launch conditions, thereby preventing loss of information about rocket whereabouts.
Solution Approach 2:
The system adds cloud-based connectivity and wireless communication capabilities to the traditional launch pad, transitioning from a standalone local system to a networked system that can store and transmit data remotely. This dimensional expansion enables long-term tracking, recovery operations, and data analysis without significantly increasing the physical complexity at the launch site itself.
3Ease of operation
If automated launch sequences are used, then the ease of operation is improved, but the control and safety over launch initiation deteriorates
Solution Approach 1:
The system requires users to perform preliminary authentication actions on their mobile devices before allowing automated launch sequences to execute. This ensures that while the launch sequence itself can be automated, the initiation is controlled by verified user actions, maintaining both ease of operation and reliable control.
