Internal Gimbal Isolation Assembly for Compact UAV Vibration Damping
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 the gimbal's ability to effectively absorb shocks and vibrations.
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 fix a load, and employing a plurality of shock-absorbing balls connected via a moving member and fixing members to absorb vibrations, allowing the gimbal and load to move relative to the body while reducing shock transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
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 body, but the space occupied increases and integration is reduced
Solution Approach 1:
The shock-absorbing assembly is merged with the aircraft body by arranging it inside the body cavity. The connecting structure integrates the shock-absorbing assembly, gimbal, and load into a unified system that occupies less space while maintaining functional separation through the body wall.
Solution Approach 2:
The shock-absorbing assembly is nested inside the aircraft body, with the connecting structure passing through the body wall to connect the internal shock-absorbing assembly with the external gimbal and load, creating a compact nested configuration.
2Ease of manufacture
If the shock-absorbing assembly is arranged outside the aircraft body, then installation is simpler, but the gimbal's ability to absorb shocks and vibrations is reduced
Solution Approach 1:
The shock-absorbing assembly is combined with the aircraft body structure, allowing the gimbal to effectively absorb shocks and vibrations while maintaining ease of installation through the integrated design.
Solution Approach 2:
The connecting structure acts as an intermediary element that transmits shocks and vibrations from the external load through the aircraft body to the shock-absorbing assembly, enabling effective shock absorption while maintaining installation simplicity.
3Reliability
If multiple shock-absorbing balls are used connected via moving member and fixing members, then vibration absorption is improved, but the structural complexity increases
Solution Approach 1:
The shock-absorbing assembly is segmented into multiple shock-absorbing balls connected via moving members and fixing members, allowing each component to independently absorb vibrations while maintaining overall structural integrity.
Solution Approach 2:
The moving members enable dynamic movement of the shock-absorbing balls relative to each other and the aircraft body, allowing the structure to adapt to various vibration frequencies and intensities while maintaining reasonable structural complexity.
