Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If integrated aircraft design is used, then structural strength is improved, but adaptability to different working conditions deteriorates
Solution Approach 1:
The aircraft is divided into modular components including inner arms, outer arms, canard wings, and fixed wings that can be independently assembled and disassembled. The outer arm is a separate module that can be quickly attached to the inner arm to transform the aircraft configuration for different working conditions such as air taxi or air ambulance operations.
2Stability of the object's composition
If integrated aircraft design is used, then structural stability is improved, but ease of operation deteriorates
Solution Approach 1:
The aircraft structure is segmented into standardized modules with defined connection interfaces. The outer arm includes a connection structure that can be quickly coupled with the inner arm, allowing non-specialized personnel to perform installation and disassembly operations while maintaining structural stability during flight.
Solution Approach 2:
The aircraft configuration is made dynamic through the ability to quickly reconfigure modular components. The outer arm can be attached or detached based on operational requirements, enabling the aircraft to adapt its structure for different missions without requiring permanent modifications or specialized technician intervention.
3Use of energy by moving object
If streamlined arm design is used, then lift motor efficiency is improved, but device complexity increases
Solution Approach 1:
The outer arm features a streamlined curved cross-section design that reduces vortex formation and aerodynamic interference with the propeller flow. This curved geometry improves lift motor efficiency by optimizing airflow patterns around the arm structure while the modular design keeps the overall device complexity manageable through standardized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design increases lift by 10-70% and improves operational efficiency by allowing quick installation and disassembly, reducing vortex interference and energy consumption.
Implementation Method 1
The outer arm body presents a streamlined design in the cross-section along its length, with the curvature of the arc at one end being smaller than that at the other end, and the cross-section gradually converging from the middle to both ends. This streamlined design can reduce the vortex formed by the interference of the propeller with a body of the aircraft, thereby increasing the efficiency of the lift motor.
