Optical Mechanism Correction Without Internal Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with lens modules, the lens module may tilt relative to the image sensor due to non-uniform driving forces, leading to focusing issues.
Innovation Solution
A correction method that measures the angle between the optical axis and a reference surface using an external apparatus, compiles the data, and transmits a signal to a driving module to adjust the optical member's position, ensuring it remains perpendicular to the reference surface without relying on an internal sensor.

Engineering Contradiction Analysis
1Reliability
If an internal sensor is used to detect the angle between the optical axis and the reference surface, then the tilting issue can be detected and corrected, but the device dimensions increase
Solution Approach 1:
The patent uses an external apparatus as an intermediary to perform angle detection instead of embedding a sensor within the optical mechanism. The external apparatus measures the angle between the optical axis and reference surface, then transmits correction data to the driving module, eliminating the need for internal sensing components and reducing device volume while maintaining detection accuracy
Solution Approach 2:
The patent replaces the mechanical sensor-based detection system with an external measurement and data transmission system. Instead of using physical sensors to detect tilt angles, the system uses external apparatus to measure angles and processes correction data through a control module, substituting mechanical detection with an external measurement approach
2Reliability
If a sensor is embedded in the optical mechanism to detect tilting, then correction can be made, but the device complexity increases
Solution Approach 1:
The patent extracts the sensing function from the optical mechanism itself and places it in an external apparatus. The angle detection, data compilation, and correction signal generation are all performed outside the optical mechanism, leaving the mechanism itself simpler while maintaining the ability to detect and correct tilting
Solution Approach 2:
The external apparatus serves multiple functions: it detects the angle between the optical axis and reference surface, compiles measurement data into correction data, and transmits signals to the driving module. This multi-functional external system replaces what would otherwise require multiple separate components within the optical mechanism

AI summary
A correction method for an optical mechanism having an optical member and a fixed portion is provided, including: an external apparatus measures the angle between the optical axis of the optical member and a reference surface of the fixed portion; the result of measuring the angle between the optical axis and the reference surface is compiled into data; the data is input into a control module; the control module transmits a signal to a driving module according to the data; and the driving module drives the optical member to rotate or move relative to the fixed portion upon receiving the signal. The optical mechanism does not include a sensor to detect the angle between the optical axis and the reference surface.
