Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the propeller holder device is fixed to the motor module through screws, then the connection is reliable, but the assembly and disassembly require special tools and are inconvenient
Solution Approach 1:
The buckling component uses elastic arms that can dynamically change their state between locked and unlocked positions. The elastic arms are designed to be flexible enough to be manually pressed and deformed, allowing the hooks to disengage from the limit portions, while maintaining a stable locked state during normal operation. This dynamic characteristic enables tool-free assembly and disassembly while ensuring reliable connection during use.
Solution Approach 2:
The connection mechanism is segmented into distinct functional components: the buckling component with elastic arms and hooks, the limit portions on the fixed seat, and the propeller holder module. This segmentation allows the buckling component to be independently manipulated for assembly and disassembly, separating the locking function from the main structural components and enabling convenient operation without affecting the overall connection reliability.
2Strength
If the propellers and fuselage are integrally formed, then the structural strength is high, but the entire UAV must be replaced when propellers are damaged
Solution Approach 1:
The UAV structure is segmented into separable components: the propeller holder module containing the propellers, the fixed seat, and the motor module. The propeller holder module can be independently removed by releasing the buckling component, allowing damaged propellers to be replaced without affecting the fuselage or requiring replacement of the entire UAV. This segmentation maintains structural integrity where needed while enabling easy maintenance of rotating components.
3Ease of operation
If a detachable propeller holder device is used, then the assembly and disassembly are convenient, but the connection stability may be compromised
Solution Approach 1:
The locking function is extracted and concentrated into the dedicated buckling component with elastic arms and hooks, which engages with the limit portions on the fixed seat. This extracted locking mechanism provides stable connection during operation while being independently controllable for assembly and disassembly. The separation of locking function from the main structural components allows convenient operation without compromising connection stability.
Solution Approach 2:
The elastic arms provide dynamic stability through their material properties. During normal operation, the elastic arms maintain a locked state with sufficient rigidity to ensure connection stability. When assembly or disassembly is needed, the elastic arms can be manually pressed to temporarily deform and release the hooks, demonstrating dynamic adaptability between stable connection and convenient operation states.

AI summary
A detachable propeller holder device includes a propeller holder module, a fixed seat and a motor module. Paddles are located the propeller holder module, a buckling component is located on the propeller holder module, the buckling component includes two elastic arms and two hooks, the two elastic arms are symmetrically located at two sides of the propeller holder module, the hooks are respectively located at an end of the two elastic arms and are respectively buckled with two limit portions which are symmetrically located at the fixed seat, so as to fix the propeller holder module to the fixed seat. In the detachable propeller holder device, only the buckling component at the side of the propeller holder module is pinched by fingers to deform inwardly till the hooks are detached from the limit portions of the fixed seat, and then the propeller holder module is pulled upwardly to be removed.
