Modular UAV Payload Mounting with Embedded Electrical Bus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching payloads to UAVs are inflexible, requiring specific connections that prevent the easy mounting or swapping of alternate payloads without modifications to the aircraft structure or the use of adapter plates.
Innovation Solution
A modular mounting system featuring lower and upper rails with an embedded electrical bus, allowing payloads to be mounted anywhere along the rails, and a locking mechanism using wedges, clamping links, and adjustable screws to securely attach payloads, enabling quick and easy installation and removal without structural modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple threaded or lug connections are used to attach a payload to the aircraft floor, then the payload can be securely attached, but the mounting structure becomes complex and modifications are required to attach alternate payloads
Solution Approach 1:
The mounting structure is divided into separate modular components: a standardized aircraft floor interface and interchangeable payload adapters. Each adapter is designed for specific payload types, allowing the main floor structure to remain unchanged while enabling different payload configurations through simple adapter changes rather than modifying the entire mounting system
Solution Approach 2:
A universal standardized interface is created on the aircraft floor that can accommodate multiple types of payloads through interchangeable adapters. This universal base structure with consistent connection points allows different payload adapters to be attached to the same location, enabling multi-functionality without requiring structural modifications to the aircraft floor
2Reliability
If specific threaded or lug connections are used for a particular payload, then secure attachment is achieved, but attaching alternate payloads requires modification to the floor structure or adapter plates
Solution Approach 1:
The aircraft floor is pre-configured with standardized connection points and interfaces during manufacturing. Payload adapters are pre-designed to match these standardized interfaces, allowing payloads to be quickly interchanged by simply detaching one adapter and attaching another without requiring any field modifications or complex alignment procedures
Solution Approach 2:
Interchangeable payload adapters serve as intermediary components between the standardized aircraft floor interface and various payload types. These adapters translate the universal floor connection standard into specific mounting configurations required by different payloads, enabling versatility while maintaining attachment security through the standardized interface
3Reliability
If multiple connection points are used to secure a payload, then the payload is firmly attached, but the load and unload process becomes time-consuming
Solution Approach 1:
The connection system incorporates dynamic quick-release mechanisms that allow the mounting state to transition rapidly between locked and unlocked positions. These mechanisms use movable components such as spring-loaded latches or cam-actuated release systems that can secure multiple connection points simultaneously with a single action, reducing the time required to attach or detach payloads while maintaining firm attachment when engaged
