Inductive Power Camera Mount for Vibration-Isolated Image Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image shooting devices, such as dashboard cameras, face challenges in suppressing camera unit shaking due to mechanical shocks from vehicle vibrations, which are transmitted through power cables.
Innovation Solution
Incorporating a power transmission-side coil in the holder and a power reception-side coil in the camera unit, opposing each other, allowing for electromagnetic induction to power the camera unit, thereby eliminating the need for a physical power cable and reducing vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a power cable is connected to the camera unit to supply power, then the camera unit can be powered, but vibration from the vehicle is transmitted through the power cable causing the camera unit to shake
Solution Approach 1:
The patent replaces the mechanical power cable connection with an electromagnetic induction system. A power transmission-side coil is mounted on the holder and a power reception-side coil is mounted on the camera unit, allowing power to be transmitted wirelessly through electromagnetic fields, thereby eliminating the mechanical connection that transmits vibration.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to transfer power from the holder to the camera unit. The power transmission-side coil generates an alternating magnetic field that induces current in the power reception-side coil, serving as a non-contact power transmission medium that does not transmit mechanical vibration.
2Stability of the object's composition
If the camera unit is movably supported to suppress shaking, then image stability can be improved, but the camera unit requires a power connection that transmits vibration
Solution Approach 1:
The patent replaces the mechanical power cable with an electromagnetic induction system, allowing the camera unit to be movably supported for image stabilization without the power cable transmitting vibration to the camera body.
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
This solution effectively suppresses camera unit shaking, reducing image blur by isolating the camera from power cable vibrations and maintaining image stability during vehicle movement.
Implementation Method 1
power can be fed from the holder side to the camera unit side through electromagnetic induction
