Detachable Camera Motor Current Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detachable cameras face issues with power consumption and motor damage due to high driving forces and varying user forces when removing or returning the camera body to the holder.
Innovation Solution
A detachable camera system with a control circuit that adjusts the driving current of the motor based on whether the camera body is on the holder, using a first current when engaged and a lower second current when disengaged, to manage power consumption and prevent motor damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the motor of the camera holder is maintained at a high driving force after the camera body is removed, then the camera holder can quickly respond when the camera body is returned, but the risk of damage to the camera and motor increases
Solution Approach 1:
The patent applies dynamics by making the driving force of the motor adjustable rather than fixed. The control circuit dynamically changes the motor's driving current based on the operational state: using a first current when the camera body is mounted and a second current (lower than the first) when the camera body is removed. This dynamic adjustment allows the system to maintain high response capability when needed while reducing damage risk during idle periods.
2Adaptability or versatility
If the camera body is frequently taken out from or returned to the camera holder, then the camera can be used in different positions, but the varying force and direction from users may easily cause damage or reduced lifespan to the motor
Solution Approach 1:
The patent applies preliminary anti-action by proactively reducing the motor's driving force when the camera body is removed, before any potential damage can occur. The control circuit detects when the camera body is not mounted and automatically lowers the current to a safer level, creating a protective state in advance that prevents damage from improper user forces during subsequent insertion operations.
3Speed
If the driving current is kept high to ensure quick camera holder movement, then the camera can be repositioned quickly, but power consumption increases
Solution Approach 1:
The patent applies periodic action by alternating between two current levels based on operational needs. The motor operates at a higher current level (first current) when the camera body is mounted and quick repositioning is needed, and switches to a lower current level (second current) when the camera body is removed and quick movement is not required. This periodic switching between high and low power states optimizes the balance between speed and power consumption.
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
The solution reduces power consumption and minimizes the risk of motor damage by lowering the driving current when the camera body is not on the holder, thereby extending the camera's lifespan.

AI summary
An operation method of a detachable camera, wherein the detachable camera includes a camera body, a camera holder, a driving element and a control circuit, the driving element is controlled by the driving element to control the camera holder, and the operation method, performed by the control circuit, includes: triggered by a trigger signal to determine whether the camera body is on the camera holder, setting a driving current of the driving element as a first current if the camera body is on the camera holder, and setting the driving current of the driving element as a second current if the camera body is not on the camera holder, wherein the second current is lower than the first current.
