Solution Overview

Problem

Current pan-tilt shock-absorbing designs for unmanned vehicles separate the pan-tilt from the aircraft, occupying large space and lacking integration, which hinders a harmonized overall design.

Innovation Solution

A shock-absorbing structure with shock-absorbing balls and a positioning structure integrated within the unmanned vehicle's body, connecting the pan-tilt assembly to the body via a moving member and fixing members, allowing the pan-tilt to be assembled internally and reducing vibration impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the pan-tilt shock-absorbing assembly is arranged outside the aircraft body and connected via a connecting wire, then the shock-absorbing function is achieved, but the overall design becomes less integrated and occupies more space

Engineering Contradiction:
Improveintegration of pan-tilt with aircraft bodyVSAvoidspace occupied by shock-absorbing assembly
Core Design Contradiction:
Device complexityVSVolume of stationary object

Solution Approach 1:

The patent merges the shock-absorbing assembly with the aircraft body by integrating the shock-absorbing balls and positioning structures directly into the body housing. The pan-tilt assembly is connected to the body through integrated fixing members and positioning structures rather than external connecting wires, achieving a more compact and harmonized overall design while maintaining shock-absorbing functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the pan-tilt is separated from the aircraft body using external connecting wires, then the shock-absorbing function is achieved, but the design lacks integration and occupies larger space

Engineering Contradiction:
Improveshock-absorbing functionVSAvoidintegration level of pan-tilt with aircraft
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The shock-absorbing function is maintained by integrating multiple shock-absorbing balls with positioning structures directly into the aircraft body. The pan-tilt assembly connects to the body through fixing members that engage with positioning structures, ensuring reliable shock absorption while achieving high integration without external connecting wires.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shock-absorbing function is divided into multiple shock-absorbing balls distributed within the body, each capable of independently absorbing shocks. This segmentation allows the system to maintain reliable shock-absorbing performance while being compactly integrated into the body structure.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If the shock-absorbing assembly is arranged externally with connecting wires, then shock absorption is achieved, but the overall design is not harmonized

Engineering Contradiction:
Improvevibration impactVSAvoidoverall design harmony
Core Design Contradiction:
Object-affected harmful factorsVSShape

Solution Approach 1:

The shock-absorbing assembly is merged with the aircraft body through integrated positioning structures and fixing members. The shock-absorbing balls are positioned within the body using integrated positioning structures, creating a harmonized overall design that effectively reduces vibration impact without external components.

Inventive Principle:
Principle #5Merging (Combining)
