Rotating Camera Frame for Stable Imaging on Irregular Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying machines with rotor blades face challenges in maintaining imaging precision when navigating irregular surfaces, as the camera tilts with the machine body, and wheels struggle to ride over steps or maintain contact on complex structures, leading to reduced drivability and imaging accuracy.
Innovation Solution
A flying machine design featuring a frame with rotating looped belts or wheels that form triangular or square shapes, allowing the camera to maintain a fixed imaging direction orthogonal to the pressing sections, enabling stable contact and smooth movement over irregular surfaces while protecting the camera and rotor blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera is fixed to the flying machine body, then the structure is simple, but the imaging precision deteriorates when navigating irregular surfaces
Solution Approach 1:
The system is divided into two independent parts: the flying machine body and the camera support frame. The frame can rotate independently relative to the body, allowing the camera to maintain its imaging direction while the body navigates irregular surfaces. This segmentation resolves the contradiction by decoupling the motion of the body from the orientation of the camera.
Solution Approach 2:
The camera support frame is made dynamically rotatable relative to the flying machine body through a rotation mechanism. This dynamic adjustment allows the camera to maintain a stable imaging direction orthogonal to the pressing sections even when the body tilts or moves over irregular surfaces, thereby maintaining imaging precision without oversimplifying the mounting structure.
2Ease of operation
If wheels are used for ground contact, then the machine can move on surfaces, but the wheels struggle to ride over steps or maintain contact on complex structures
Solution Approach 1:
The pressing sections extend in the width direction of the frame body, creating a broader contact area with the target object. This dimensional extension allows the frame to bridge gaps and ride over steps more effectively, improving contact stability while maintaining mobility through the rotating mechanism.
3Measurement precision
If the frame rotates to maintain camera alignment, then imaging precision improves, but the device complexity increases
Solution Approach 1:
The rotating frame serves multiple functions: it supports the camera, provides a stable imaging platform, and actively compensates for body tilts to maintain imaging precision. By consolidating these functions into a single rotating assembly, the design achieves high imaging precision without proportionally increasing overall device complexity.
4Reliability
If the frame body is enclosed to protect rotor blades and camera, then safety improves, but the device complexity increases
Solution Approach 1:
The protective enclosure is merged with the frame body structure itself. The frame body serves dual purposes: it supports the rotating camera frame and simultaneously provides protective enclosure for the rotor blades and camera. This integration achieves comprehensive protection without adding separate enclosure components, thereby avoiding excessive complexity.

AI summary
A flying machine includes a flying machine body including a rotor blade; a frame including a frame body supporting the flying machine body, and a pressing section that is pressed against a target object at least at two locations separated along a direction orthogonal to a width direction of the frame body; and a detector fixed to the frame, and having a detection direction that is a direction orthogonal to a direction joining the two locations together and facing toward the target object.
