Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rapid-configuration structure is designed to enable the aircraft to meet varying cruise payload demands, then adaptability is improved, but device complexity increases
Solution Approach 1:
The canard wing is divided into an inner section (fixed to the fuselage) and an outer section (detachably mounted on the arm). This segmentation allows the outer section to be rapidly added or removed to adjust the wing span and lift characteristics according to payload requirements, while the simple inner section maintains low structural complexity.
Solution Approach 2:
The canard wing configuration is made dynamic through the detachable outer section that can be quickly installed or removed. This allows the aircraft to transition between different wing span configurations (small for low payload, large for high payload) to optimize performance for varying mission requirements.
2Productivity
If a rapid-configuration structure is designed, then productivity is improved, but device complexity increases
Solution Approach 1:
The canard wing is divided into an inner section (fixed to the fuselage) and an outer section (detachably mounted on the arm). This segmentation allows the outer section to be rapidly added or removed to adjust the wing span and lift characteristics according to payload requirements, while the simple inner section maintains low structural complexity.
Solution Approach 2:
The arm is pre-installed on the fuselage with positioning members and locking members in place before flight operations. This preliminary preparation enables the outer section to be quickly attached or detached during rapid configuration operations without requiring complex assembly procedures, thus improving productivity while maintaining structural simplicity.
3Reliability
If positioning members with different diameters are used, then reliability is improved, but device complexity increases
Solution Approach 1:
Different positioning members have different diameters optimized for their specific locations and load conditions. The first positioning member (on the arm) has a larger diameter to withstand greater stress, while the second positioning member (on the outer section) has a smaller diameter. This local optimization improves reliability without requiring a completely complex positioning system.
