Motorized Holder Control for Detachment Overload Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding apparatuses for electronic devices, such as cameras or mobile phones, often experience overload damage when the device is detached while the driving mechanism is still active, leading to stalling and potential damage.
Innovation Solution
A holding device with a support base and a driving member, equipped with a control circuit that detects the mounting state of the electronic device and controls the power output of the driving member to prevent overload by stopping or reducing power when the device is detached or if the transition between stable states exceeds a preset duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving device is kept running to facilitate adjustment of shot angle, then the ease of operation is improved, but the reliability deteriorates when the electronic device is detached causing stall and overload damage
Solution Approach 1:
The control circuit continuously monitors the mounting state of the electronic device and the operational status of the driving device. When detachment is detected or abnormal stall conditions are identified, the control circuit automatically adjusts the driving device power output, creating a closed-loop feedback system that prevents overload damage while maintaining operational convenience during normal use
Solution Approach 2:
The control circuit is configured to detect mounting state changes and adjust driving device power before actual damage can occur. By preliminarily detecting the detachment state or abnormal operational conditions and preemptively adjusting power output, the system prevents the harmful effects of stall and overload from manifesting

AI summary
Disclosed is a holding device having a support base for holding an electric device and a driving member for driving the support base. Upon mounting the electronic device on the holding device, the holding device has at least two stable states, and the holding device stores a preset time duration for transitioning from the first stable state to the second stable state. The holding device further includes a control circuit, which, in response to a time during which the holding device transitions from the first stable state to the second stable state exceeds the preset time duration, controls the driving member to stop or reduce a power output.
