Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a multicopter flies freely without direction restriction, then it has high mobility and flexibility, but it cannot accurately arrive at the target position due to control errors and external factors
Solution Approach 1:
The linear member acts as an intermediary physical guide between the multicopter and the target position. Instead of relying solely on complex control systems to achieve precise landing, the linear member serves as a mechanical mediator that automatically guides the multicopter along the correct trajectory, eliminating the need for highly precise control while ensuring accurate arrival at the target position.
2Reliability
If the multicopter is equipped with robust propeller guards for safety, then collision damage is mitigated, but the structure becomes heavier and more complex
Solution Approach 1:
The safety function is segmented into two parts: (1) simple propeller guards that provide basic protection, and (2) the linear member guidance system that prevents off-course flight and ensures accurate landing. This segmentation allows each component to be simpler while collectively achieving high safety without excessive structural complexity.
3Weight of moving object
If the multicopter uses simple propeller guards for weight reduction, then the structure is lighter, but damage mitigation capability is insufficient
Solution Approach 1:
The linear member serves as an intermediary safety mechanism that prevents the multicopter from deviating into dangerous areas. By providing physical guidance along a safe trajectory, it complements the simple propeller guards, ensuring that even with minimal guards, the overall system achieves high safety through the mediating role of the linear member.
4Measurement precision
If precise control systems are used to maintain navigation accuracy, then the multicopter can accurately follow the navigation route, but the control system becomes more complex and difficult to manage
Solution Approach 1:
The linear member acts as a physical intermediary that replaces the need for complex control systems. Instead of relying on sophisticated software and sensors to maintain navigation accuracy, the linear member provides automatic mechanical guidance, making the control operation simpler while ensuring the multicopter accurately follows the intended route to the target position.
