Integrated Gimbal Shock-Absorbing Structure for Compact UAV Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gimbal shock-absorbing designs for aircraft separate the gimbal from the aircraft, occupying large space and lacking integration, which affects vibration absorption efficiency.
Innovation Solution
An unmanned vehicle design incorporating a gimbal assembly with a shock-absorbing structure integrated inside the body, using a connecting structure outside to fixly connect shock-absorbing balls to the body, allowing the gimbal and load to move relative to the body while absorbing vibrations through elastic materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shock-absorbing assembly is arranged outside the aircraft body and connected via a connecting wire, then the gimbal can be separated from the aircraft for independent shock absorption, but the design occupies relatively large space and reduces integration between gimbal and aircraft
Solution Approach 1:
The shock-absorbing structure is integrated inside the aircraft body, merging the previously separate shock-absorbing assembly with the aircraft structure. This eliminates the need for external arrangement and connecting wires, reducing occupied space while maintaining shock absorption functionality through the connecting structure that links the shock-absorbing structure to the gimbal assembly.
2Reliability
If the shock-absorbing assembly is arranged outside the aircraft body, then the gimbal and aircraft can be separated for independent shock absorption, but the integration between gimbal and aircraft is reduced
Solution Approach 1:
The shock-absorbing structure is merged with the aircraft body by arranging it inside the body and connecting it through a connecting structure. This integration maintains vibration absorption efficiency while improving the overall integration level between the gimbal and aircraft, eliminating the need for separate external assemblies and connecting wires.
3Volume of moving object
If the shock-absorbing structure is integrated inside the body with connecting structure outside, then space is optimized and integration is improved, but the structure becomes more complex
Solution Approach 1:
The shock-absorbing system is segmented into distinct functional components: the shock-absorbing structure inside the body, the connecting structure that bridges inside and outside, and the gimbal assembly outside. This segmentation allows each component to be optimized independently while working together as an integrated system, managing complexity through functional decomposition.
