Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the housing is closed for rolling, then the robot can move rapidly and stably on flat surfaces, but the robot cannot navigate complex and rugged terrains
Solution Approach 1:
The housing transitions from a closed fixed configuration to an open adjustable configuration, allowing the robot to dynamically adapt between rolling mode (for speed on flat surfaces) and flying mode (for terrain navigation). The first and second shells can be separated or closed based on operational needs, providing dynamic versatility.
Solution Approach 2:
The robot integrates both rolling and flying capabilities within a single system. The housing can serve dual purposes: enclosing mechanisms for rolling movement and providing an open framework for aerial navigation. The rotary wing assembly can be deployed or retracted, enabling the robot to perform multiple functions depending on terrain conditions.
2Adaptability or versatility
If the rotary wing assembly is extended for flight, then the robot achieves high flight maneuverability, but the device complexity increases
Solution Approach 1:
The rotary wing assembly is nested within the housing structure when not in use. The folding arm, tilting arm, and rotary wing can be retracted into the housing cavity, creating a compact configuration. When flight is required, the assembly extends outward from the nested position, providing maneuverability only when needed.
Solution Approach 2:
The rotary wing assembly is divided into separable components: folding arm, tilting arm, and rotary wing. This segmentation allows each component to be independently folded or extended, reducing overall complexity when not in use while maintaining full functionality when deployed. The modular structure enables easier integration and maintenance.
3Adaptability or versatility
If the first shell and second shell are separated for flight, then the robot can fly with high maneuverability, but the structural stability decreases
Solution Approach 1:
The housing dynamically transitions between closed (first shell and second shell joined) and open (shells separated) configurations. During flight, the shells are separated to allow rotary wing operation and maintain aerodynamic stability. During rolling, the shells are joined to provide structural rigidity and protect internal mechanisms.
Solution Approach 2:
The telescopic assembly acts as an intermediary mechanism between the first shell and second shell, enabling controlled separation and rejoining. This intermediary structure allows stable connection during rolling mode and controlled separation during flight mode, maintaining structural integrity when needed while enabling flight capability when required.
