Camera Posture Change Detection Using Photoelectric Baffle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cameras often fail to maintain the desired monitoring position due to unintended rotation caused by shakes or external forces, leading to degraded user experience.
Innovation Solution
A photoelectric baffle structure with baffle pieces and a photo interrupter system that detects posture changes by monitoring the alignment and output signal changes, allowing for posture restoration to the initial position when changes are not user-induced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation part is made rotatable for user operation, then the camera can be directed to different monitoring positions, but the operation part may be rotated due to shake or external forces causing unintended posture changes
Solution Approach 1:
The patent employs a feedback mechanism where a sensor detects the actual posture of the camera and feeds this information back to a controller. The controller compares the detected posture with the target posture and automatically adjusts the camera position to compensate for unintended rotations caused by shakes or external forces, thereby maintaining monitoring position stability while preserving manual operability.
Solution Approach 2:
The camera system performs self-correction of posture deviations through its own sensing and actuation components. The sensor detects posture changes and the controller automatically restores the intended positioning without requiring user intervention, enabling the system to service itself against disturbance forces.
2Reliability
If automatic posture restoration is implemented to correct unintended rotation, then monitoring position stability is improved, but device complexity increases due to additional sensing and control components
Solution Approach 1:
The patent replaces complex mechanical anti-shake mechanisms with a sensor-based detection and electronic control system. Instead of using heavy mechanical gimbals or complex spring-damper systems, the invention uses lightweight sensors to detect posture changes and electronic actuators to restore positioning, significantly reducing overall device complexity while achieving the same stability goal.

AI summary
A device for detecting posture change of a operation part in a camera and a method for restoring posture are disclosed. The device may include a photo interrupter and a photoelectric baffle structure including a plurality of baffle pieces fixed on a base. The baffle pieces may include a first baffle piece and remaining second baffle pieces of a length specification different from that of the first baffle piece, and there is a gap between two adjacent baffle pieces. An output signal from the photo interrupter changes according to the aligning relationship between the photo interrupter and the baffle pieces. One of the photoelectric baffle structure and the photo interrupter may follow the motion of an operation part of the camera while the other one remains unmoved, so that a posture change of the operation part may be detected based on the output signal from the photo interrupter.
