Retractable Camera Ejection Control for Obstruction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with retractable cameras risk damage during ejection due to obstruction or external interference, leading to potential mechanical failure.
Innovation Solution
Implement a method and device to detect conditions indicating a risk of camera damage before ejection, disabling the ejection instruction when such risks are detected, and allowing ejection only when conditions are favorable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal directly ejects the retractable camera after receiving the ejection instruction, then the camera can be used immediately, but the camera may be damaged if the ejection position is blocked
Solution Approach 1:
The patent applies preliminary action by performing obstruction detection before executing the camera ejection operation. The control unit detects whether the ejection position is blocked using sensor data (proximity sensors, light sensors, or camera-based detection) before commanding the motor to eject the camera. This preliminary check prevents damage by ensuring the path is clear before the mechanical ejection action occurs.
Solution Approach 2:
The patent applies preliminary anti-action by implementing a preventive control mechanism that actively identifies and counteracts potential damage risks before they materialize. The system detects obstruction conditions and generates counter-instructions to prevent the ejection command from being executed, thereby neutralizing the harmful effect of forced ejection into blocked positions.
2Reliability
If the mobile terminal detects obstruction and prevents camera ejection, then camera damage is avoided, but the camera cannot be used when needed
Solution Approach 1:
The patent applies dynamics by making the camera ejection state adaptable and changeable based on real-time environmental conditions. The control unit continuously monitors obstruction status and dynamically adjusts the camera's ejection state - keeping it retracted when blocked, allowing ejection when clear. This dynamic response ensures the camera is available for use whenever conditions permit, rather than being permanently restricted.
Solution Approach 2:
The patent applies feedback by implementing a closed-loop control system where sensor data about the ejection environment is continuously fed back to the control unit. The control unit processes this feedback information and adjusts the camera ejection state accordingly - permitting ejection when no obstruction is detected and preventing ejection when obstruction is detected, thereby balancing protection with availability.

AI summary
The present disclosure relates to a method, device, and storage medium for controlling a retractable camera. The method can include receiving an instruction for ejecting the retractable camera, detecting whether the mobile terminal meets a condition indicating that the camera has a risk of damage when being ejected, and disabling the instruction for ejecting the retractable camera when the mobile terminal meets the condition indicating that the camera has a risk of damage when being ejected. In the present disclosure, after the instruction for ejecting the retractable camera is received, the retractable camera is not ejected immediately. On the contrary, the mobile terminal is first determined whether meets the condition indicating that the camera has a risk of damage when being ejected. When the mobile terminal meets the condition indicating that the camera has a risk of damage when being ejected, the instruction for ejecting the camera is disabled.
