Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAVs face inefficiencies in transportation due to electronically controlled delivery mechanisms being weight and cost-intensive, and mechanical structures prone to automatic decoupling issues during landing, requiring operator intervention.
Innovation Solution
A UAV with a delivery structure comprising a mounting piece, reset assembly, and limiting piece, where the mounting groove opens upward, the reset assembly deforms under load, and the limiting piece is magnetically connected to seal the groove, allowing automatic release and preventing premature decoupling upon landing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an electronic-controlled delivery mechanism is used, then the delivery control is precise, but the weight and manufacturing cost of the UAV increase
Solution Approach 1:
The patent replaces the electronic-controlled delivery mechanism with a purely mechanical delivery structure. The mounting piece, reset assembly, and limiting piece work together through mechanical deformation and magnetic adsorption to achieve automatic delivery control without electronic components, thereby reducing UAV weight and manufacturing cost while maintaining delivery control precision
Solution Approach 2:
The mechanical delivery structure achieves automatic delivery control through self-service mechanisms. The reset assembly automatically deforms under cargo weight and resets when the cargo touches the ground, and the limiting piece automatically opens or seals the mounting groove based on cargo position, eliminating the need for electronic control signals and external intervention
2Device complexity
If a mechanical delivery structure without limiting piece is used, then the structure is simple, but the cargo can be easily separated from the mounting piece during landing, requiring operator intervention
Solution Approach 1:
The limiting piece acts as an intermediary component between the reset assembly and the mounting groove. It receives control signals from the reset assembly through magnetic adsorption and executes the sealing or opening action on the mounting groove, preventing direct complex mechanical linkages while ensuring reliable cargo attachment during landing
3Ease of operation
If the mounting groove opening faces upward, then the cargo can be easily hooked, but the cargo may be easily separated under the action of the reset assembly before lifting
Solution Approach 1:
The limiting piece performs a preliminary sealing action on the mounting groove before the cargo is lifted. By sealing the groove opening, it prevents the cargo from being accidentally separated by the reset assembly during the hooking and preparation phase, while still allowing easy cargo insertion when the groove is open
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables automatic and efficient delivery of cargo without operator intervention, ensuring reliable attachment and detachment of the cargo during transport and landing, enhancing UAV operational efficiency.
Implementation Method 1
the second end of the limiting piece can be connected with the mounting piece by magnetic adsorption to seal the opening of the mounting groove

AI summary
A UAV body and a delivery structure, wherein the delivery structure has a mounting piece, a reset assembly and a limiting piece. The reset piece deforms when the piece to be transported is lifted, which resets to drive the piece to leave the mounting groove when the piece to be transported touches the ground. The first end of the limiting piece is connected to the reset piece, and when the piece to be transported is not lifted, the second end of the limiting piece can be connected to the mounting piece by magnet to seal the opening of the mounting groove. The reset piece drives the limiting piece to move so as to separate the second end from the mounting piece when the piece to be transported is lifted.
