Camera Gyro Sensor Merged Lens Substrate Soldering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In camera devices, the placement of the gyro sensor adjacent to the lens driving device's terminal soldering area makes soldering difficult, leading to increased size of the printed circuit board due to the gyro sensor being displaced from the lens actuator.
Innovation Solution
The camera device incorporates a design where the first and second lens driving devices are disposed on the printed circuit board, with a sensor base between the printed circuit board and the lens driving device, allowing for efficient placement and reduced size of the printed circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gyro sensor is disposed adjacent to the terminal of the lens driving device for soldering, then the size of the printed circuit board increases, but the soldering work becomes difficult
Solution Approach 1:
The gyro sensor is integrated onto the lens driving device substrate itself, merging the functions of the gyro sensor and lens driving device into a single substrate. This eliminates the need for separate placement on the printed circuit board, reducing the overall board size while maintaining soldering accessibility.
Solution Approach 2:
The gyro sensor is nested within the lens driving device structure by placing it on the same substrate. This nested arrangement allows the gyro sensor to occupy space that would otherwise be part of the lens driving device assembly, thereby reducing the required printed circuit board area without compromising soldering access.
2Ease of manufacture
If the gyro sensor is spaced apart from the lens actuator, then the soldering work becomes easier, but the size of the printed circuit board increases
Solution Approach 1:
By merging the gyro sensor and lens driving device onto a single substrate, the invention achieves both easy soldering (as a single unit) and compact size (by eliminating separate placement requirements). The integrated substrate serves as both the mounting platform for the lens actuator and the gyro sensor.
Solution Approach 2:
The lens driving device substrate serves multiple functions: it acts as the mounting platform for the lens actuator, the gyro sensor, and provides the soldering interface. This multi-functional substrate eliminates the need for separate dedicated boards for each component, reducing overall size while maintaining manufacturing ease.
3Ease of manufacture
If the gyro sensor is placed on the printed circuit board separately, then the soldering area is sufficient, but the overall device size increases
Solution Approach 1:
The gyro sensor is merged with the lens driving device on a common substrate, reducing the total volume required for both components. This integration eliminates the need for separate mounting space on the printed circuit board, thereby reducing the overall camera device volume while maintaining adequate soldering area on the integrated substrate.
