Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera gimbals are large, expensive, and not portable, and they fail to accommodate various camera weights and form factors, while also obstructing the camera's field of view and not effectively stabilizing video captured from different mount platforms.
Innovation Solution
A detachable electronic gimbal ecosystem with a 3-axis stabilization system, including an inertial measurement unit and electronic motors, that can be removably coupled to various mount platforms, allowing for platform-specific behavior and minimizing obstruction, while providing stabilization and communication between the camera and the mount platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional gimbal system is used for stabilization, then video stability is improved, but the device becomes large, expensive, and non-portable
Solution Approach 1:
The gimbal system is divided into separate modular components: a camera module that can be detached and replaced, and a handle assembly with integrated stabilization. This segmentation allows the stabilization system to be shared across multiple cameras, reducing overall system cost and complexity while maintaining video stability.
Solution Approach 2:
The handle assembly is designed as a universal platform that can accommodate multiple different camera types and weights. The integrated gimbal stabilization system serves all camera configurations, eliminating the need for separate gimbals for each camera and reducing overall device complexity and cost.
2Reliability
If a fixed gimbal design is used, then stabilization is achieved, but it cannot accommodate various camera weights and form factors
Solution Approach 1:
The gimbal system incorporates dynamic adjustment capabilities that allow it to adapt to different camera weights and form factors. The system can modify its stabilization parameters and motor torque based on the detected camera characteristics, maintaining effective stabilization across various camera configurations without requiring a fixed design.
Solution Approach 2:
The system changes operational parameters such as motor torque, stabilization speed, and balance compensation based on the specific camera attached. This parameter adaptation allows the same gimbal hardware to effectively handle various camera weights and form factors while maintaining stabilization performance.
3Reliability
If a traditional gimbal mounting system is used, then stabilization is provided, but it obstructs the camera's field of view
Solution Approach 1:
The gimbal mounting system is repositioned to the handle assembly rather than being attached directly to the camera body. This spatial reconfiguration moves the stabilization components to a different dimension relative to the camera, eliminating obstruction of the field of view while maintaining stabilization functionality through the optical axis.

AI summary
Disclosed is an electronic gimbal with camera and mounting configuration. The gimbal can include an inertial measurement unit which can sense the orientation of the camera and three electronic motors which can manipulate the orientation of the camera. The gimbal can be removably coupled to a variety of mount platforms, such as an aerial vehicle, a handheld grip, or a rotating platform. Moreover, a camera can be removably coupled to the gimbal and can be held in a removable camera frame. Also disclosed is a system for allowing the platform, to which the gimbal is mounted, to control settings of the camera or to trigger actions on the camera, such as taking a picture, or initiating the recording of a video. The gimbal can also provide a connection between the camera and the mount platform, such that the mount platform receives images and video content from the camera.
