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 of launch control deteriorates
Solution Approach 1:
The launch control system is divided into multiple independent safety modules: proximity detection module, physical key module, and confirmation sequence module. Each module performs a specific safety function and operates independently, preventing accidental launches while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The system performs preliminary safety checks before allowing launch: proximity detection is performed in advance, physical key insertion is required beforehand, and multiple confirmation steps must be completed prior to ignition. These preliminary actions ensure safety is established before the critical ignition event occurs.
2Reliability
If multiple safety confirmation steps are implemented, then the reliability of launch control is improved, but the ease of operation deteriorates
Solution Approach 1:
The proximity detection system automatically detects the user's presence and enables/disables launch control without manual intervention. The physical key automatically authenticates the user when inserted. These self-service mechanisms handle safety checks automatically, reducing the operational burden on the user while maintaining high reliability.
Solution Approach 2:
Multiple safety functions are merged into a single integrated launch controller that manages proximity detection, physical key authentication, and confirmation sequences through a unified interface. This consolidation presents a simplified operational workflow to the user while incorporating multiple safety layers in the background.
3Object-affected harmful factors
If proximity detection and physical key requirements are added, then the safety against accidental launches is improved, but the device complexity increases
Solution Approach 1:
A physical key serves as an intermediary between the user and the launch control system. It provides a simple mechanical authentication mechanism that doesn't require complex electronics or programming, adding a layer of security against accidental launches while maintaining relatively simple implementation.
Solution Approach 2:
The system replaces complex electronic authentication mechanisms with simpler mechanical and optical solutions: proximity detection using optical sensors instead of complex electronic identifiers, and physical key insertion instead of electronic card readers or biometric scanners. This substitution reduces device complexity while maintaining safety.
4Reliability
If a cloud-based tracking system is implemented, then the recovery capability of model rockets is improved, but the use of energy and device complexity increases
Solution Approach 1:
Instead of requiring continuous active communication and complex tracking hardware on the rocket, the system uses a simplified approach where the rocket transmits its identity and trajectory data briefly during flight, and the cloud system maintains a database copy of launch information. This reduces the energy requirements of the rocket while enabling comprehensive tracking and recovery capabilities.
