Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with camera functions face challenges in capturing clear images and videos due to shaking, making it inconvenient for users to record stable videos while following moving objects.
Innovation Solution
A device cradle with rotating capabilities, featuring a fixer and body portion that allows horizontal and vertical rotation, equipped with motors and gears to adjust the device's position, ensuring a moving object remains within the screen's frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile phone is held manually for video recording, then the user can move with the object being recorded, but the video becomes unstable and unclear due to shaking
Solution Approach 1:
The patent introduces a tripod as an intermediary support device between the user and the mobile phone. The tripod's adjustable arm and clamp mechanism serve as a mediator that provides stable support for the mobile phone while allowing the user to operate it remotely, thus eliminating hand-shaking issues while maintaining operational flexibility
Solution Approach 2:
The tripod incorporates dynamic adjustment capabilities through its adjustable arm length, height, and angle. These dynamic features allow the tripod to adapt to different recording scenarios and distances, providing stability while maintaining the ability to reposition the mobile phone as needed
2Stability of the object's composition
If a tripod is used for stable video recording, then video stability improves, but the user cannot easily adjust the device position or follow moving objects
Solution Approach 1:
The tripod features dynamic adjustability with an arm that can be extended or retracted, and a clamp mechanism that allows the mobile phone to be positioned at various angles and distances. This dynamic structure enables the tripod to adapt to different recording needs while maintaining stability
Solution Approach 2:
The tripod is designed with universal adaptability, allowing it to accommodate different mobile phone sizes and recording scenarios. The adjustable arm and clamp mechanism provide multi-functional positioning capabilities, enabling the same device to serve various recording purposes
3Stability of the object's composition
If a fixed-position device holder is used, then device stability is maintained, but the device cannot rotate to track moving objects
Solution Approach 1:
The patent implements a rotating clamp mechanism that allows the mobile phone to rotate horizontally and vertically while maintaining a stable base. This dynamic rotation capability enables the device to track moving objects across different angles while the tripod base remains stationary and stable
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy adjustment and stabilization of mobile devices, allowing for clear video recording and image capture of moving objects without the need for manual movement.
Implementation Method 1
a first driving portion configured to rotate the fixer by a specified angle around a horizontal axis with respect to the body portion
Implementation Method 2
at least one gear configured to transmit the torque
