Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAVs face issues with electronically controlled delivery mechanisms that are prone to interference and increase weight and cost, and mechanical delivery structures often result in inefficient decoupling of transported items during landing.
Innovation Solution
A UAV with a delivery structure comprising a mounting piece, reset assembly, and limiting piece, where the mounting groove opens upwards, the reset assembly deforms under the weight of the item, and the limiting piece magnetically seals the groove until the item is lifted, ensuring automatic decoupling upon landing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a mechanical delivery structure with reset assembly is used, then automatic decoupling is realized, but the piece to be transported can be easily separated before lifting
Solution Approach 1:
The limiting piece acts as an intermediary component between the reset assembly and the mounting groove. It mediates the reset force by selectively blocking or allowing the reset piece to push the piece to be transported, thereby controlling when decoupling occurs. This solves the problem of premature separation while maintaining automatic decoupling functionality.
Solution Approach 2:
The limiting piece preliminarily blocks the reset assembly's action before the piece is lifted. By preventing the reset piece from pushing the piece to be transported during the hovering phase, it ensures the piece remains securely in place. The blocking action is removed only when the piece is properly lifted, allowing controlled decoupling at the appropriate time.
2Ease of operation
If the mounting groove opening faces upwards for easy loading, then loading is simplified, but the piece to be transported may fall out during transportation
Solution Approach 1:
The limiting piece dynamically changes the state of the mounting groove opening. It blocks the opening during transportation to prevent piece drop, and unblocks when the piece is lifted to allow decoupling. This dynamic adjustment maintains both loading convenience and piece retention reliability.
Solution Approach 2:
The delivery structure is segmented into functional zones: the mounting groove for loading, the limiting piece for retention, and the reset assembly for decoupling. This segmentation allows the groove to remain open for easy loading while the limiting piece provides selective blocking to prevent piece drop during transport.
3Measurement precision
If electronic-controlled delivery mechanism is used, then precise control is achieved, but weight and manufacturing cost increase
Solution Approach 1:
The patent replaces electronic-controlled delivery mechanisms with a purely mechanical delivery structure comprising mounting piece, reset assembly, and limiting piece. This mechanical system achieves precise control through the interaction of elastic reset force and magnetic blocking force, eliminating the need for electronic actuators and reducing UAV weight.
Solution Approach 2:
The mechanical delivery structure is self-service in that it automatically controls the piece retention and release without electronic intervention. The reset assembly automatically pushes the piece for decoupling when the limiting piece is removed, and the magnetic force automatically holds the piece when the limiting piece is in place, eliminating the need for electronic control systems.

AI summary
The invention relates to the technical field of unmanned aerial vehicle (UAV) transportation, and discloses a UAV, which comprises a UAV body and a delivery structure, wherein the delivery structure comprises a mounting piece (1), a reset assembly (2) and a limiting piece (3). The reset piece (21) is configured to deform when the piece to be transported (100) is lifted, which resets to drive the piece to leave the mounting groove (11) when the piece to be transported (100) touches the ground. The first end of the limiting piece (3) is connected to the reset piece (21), and when the piece to be transported (100) is not lifted, the second end of the limiting piece (3) can be connected to the mounting piece (1) by magnet to seal the opening of the mounting groove (11). The reset piece (21) can drive the limiting piece (3) to move so as to separate the second end from the mounting piece (1) when the piece to be transported (100) is lifted. The UAV can realize the automatic release of the piece to be transported (100), and limit the position when the piece to be transported (100) is not lifted, so as to avoid a fall from the mounting groove (11). The limiting piece (3) can open the mounting groove (11) after lifting. The invention can enable automatic decoupling of the piece to be transported (100) after landing, thereby enabling UAV convenience and high transportation efficiency.
