Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite wing unmanned aerial vehicles (UAVs) face difficulties in disassembling and assembling their detachable wings due to complex locking structures, which complicates transportation and maintenance.
Innovation Solution
A quick-release wing structure featuring a lock cylinder assembly with a sliding lock plate and a lock head that allows for easy attachment and detachment by using a clamping mechanism, enhanced by a bolt, elastic parts, and specific slot designs for stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex locking structures are used to ensure connection strength, then the reliability of wing attachment is improved, but the ease of operation for disassembly and assembly deteriorates
Solution Approach 1:
The locking structure is divided into separate functional components: a lock head with locking slot on the wing side, and a lock plate with clamping hole on the fuselage side. This segmentation allows each component to be simple in structure while achieving reliable connection through their coordinated interaction during the locking process.
Solution Approach 2:
The locking mechanism achieves automatic locking through self-service design. When the lock head is inserted into the fuselage, the lock plate automatically moves to the locking position under elastic force, and the locking slot and lock plate automatically engage without requiring additional manual operations, thus simplifying the assembly process while ensuring reliable connection.
2Adaptability or versatility
If detachable wings are designed for easy transportation, then the adaptability of the UAV is improved, but the reliability of wing-fuselage connection deteriorates
Solution Approach 1:
The locking slot on the lock head and the lock plate feature arc-shaped grooves that match each other. This curved geometry ensures reliable connection through precise geometric fitting while maintaining the detachable nature of the wing structure for easy transportation.
Solution Approach 2:
The elastic part changes its physical state (compressed during insertion, expanded during locking) to drive the lock plate between locked and unlocked positions. This parameter change enables the structure to transition between secure connection and easy detachment states.
3Ease of operation
If simple locking structures are used for quick assembly, then the ease of operation is improved, but the reliability of connection deteriorates
Solution Approach 1:
The lock plate is pre-positioned within the lock cylinder assembly and the elastic part is pre-loaded. When the lock head is inserted, these pre-positioned components automatically engage without requiring additional manual operations, achieving both quick assembly and reliable connection.
Solution Approach 2:
The lock plate serves as an intermediary component between the lock head and the fuselage. It mediates the connection by automatically moving to engage with the locking slot, ensuring reliable connection while maintaining the simplicity and speed of the assembly process.

AI summary
A quick-release wing structure includes a lock cylinder assembly and a lock head. The lock cylinder assembly is installed in the fuselage. The lock cylinder assembly includes a shell and a lock plate. An installation slot is opened inside the shell. The side wall of the installation slot is provided with a clamping hole connected with the installation slot. The lock plate is sliding and arranged in the installation slot. The lock head is installed in the wing. A locking slot is set on the periphery of the lock head. The lock head can pass through the clamping hole and drive the lock plate to move. When the locking slot is facing the lock plate, the lock head is clamped onto the locking slot and fixed. The UAV includes the quick-release wing structure described above.
