Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If composite-wing UAV uses multi-rotor vertical landing, then vertical takeoff and landing capability is achieved, but structural weight increases and service life reduces due to impact energy absorption issues
Solution Approach 1:
The patent applies beforehand cushioning by installing a shock-absorbing component connected to the lower end plate of the tail body frame. This shock absorber is pre-configured to cushion the impact energy during landing, preventing direct transmission of impact forces to the structural components and electrical systems, thereby extending service life while maintaining vertical landing capability
2Adaptability or versatility
If composite-wing UAV has fixed wings and multiple rotors, then vertical takeoff and landing capability is achieved, but structural weight increases
Solution Approach 1:
The patent applies segmentation by dividing the UAV into modular components including a tail body frame with lower and upper end plates, a shock-absorbing component, and electrical components with quick installation assemblies. This modular segmentation allows for optimized weight distribution and selective placement of heavy components, reducing overall structural weight while maintaining vertical takeoff and landing capability
3Adaptability or versatility
If composite-wing UAV structure and electrical components absorb impact energy, then vertical landing is achieved, but damage increases and service life reduces
Solution Approach 1:
The patent applies taking out by extracting the shock-absorbing function from the main structural components and electrical systems, and concentrating it in a dedicated shock-absorbing component connected to the lower end plate. This extraction prevents impact energy from being absorbed by fragile electrical components and critical structural elements, thereby reducing damage and extending service life
4Ease of repair
If quick installation assembly of circuit is used, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by designing the electrical components with quick installation assemblies that allow for dynamic reconfiguration and rapid replacement. The bias piece and positioning sleeve create a flexible connection system that can be quickly assembled and disassembled, improving ease of repair while the modular nature actually reduces overall system complexity compared to permanent fixed connections
