Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging drive module includes multiple components assembled together to achieve autofocus and image stabilization functions, then the functionality is improved, but the structure becomes complex and assembly difficulty increases
Solution Approach 1:
The patent combines the autofocus drive components (focusing coil, focusing magnetic steel, first circuit board) and image stabilization drive components (anti-shake coil, anti-shake magnetic steel, second circuit board) into a single integrated imaging drive module. This merging approach maintains comprehensive functionality while reducing overall structural complexity and assembly difficulty compared to separate modules.
2Adaptability or versatility
If the imaging drive module includes numerous components assembled together, then the functionality is improved, but the assembly process becomes intricate and product yield decreases
Solution Approach 1:
The patent integrates multiple drive components into a unified imaging drive module with a coordinated assembly structure. The first bracket, second bracket, and housing form an integrated assembly that guides and constrains all components, simplifying the assembly process and improving product yield by reducing the complexity of assembling numerous separate components.
3Adaptability or versatility
If the imaging drive module integrates multiple functions, then the functionality is improved, but the assembly process becomes difficult and affects product yield
Solution Approach 1:
The patent segments the imaging drive module into functional sub-components (focusing drive section with first bracket, anti-shake drive section with second bracket, housing) that can be assembled in a coordinated manner. This segmentation allows for modular assembly while maintaining integrated functionality, making the manufacturing process easier and more reliable.
4Productivity
If the lens module, focusing drive module, and anti-shake drive module are fixed into a one-piece structure, then the assembly is simplified and productivity is improved, but the device thickness may increase
Solution Approach 1:
The patent employs a nested arrangement where the first bracket and second bracket are positioned within the housing in a compact, space-efficient manner. The focusing coil and anti-shake coil are arranged in different spatial zones within the same housing volume, allowing the one-piece structure to maintain thin profile while integrating multiple functions.

Function Achieved in This Case
The modular design simplifies the assembly process, increases product yield, and ensures effective focusing and anti-shake functions, thereby guaranteeing camera quality while reducing the thickness of the camera device.
Implementation Method 1
a first circuit board, the first circuit board being electrically connected to the focusing coil to enable an interaction between the focusing coil and the focusing magnetic steel to drive the lens barrel to move along a direction of an optical axis of the lens module
Implementation Method 2
the second circuit board is electrically connected to the focusing coil to enable an interaction between the anti-shake coil and anti-shake magnetic steel to drive the image sensor relative to the lens module to move along a direction around the optical axis or along a direction perpendicular to the optical axis

AI summary
The present application relates to a camera device and electronic device. The camera device includes a lens module, a focusing drive module and an anti-shake drive module sequentially fixed into a one-piece. The lens module, the focusing drive module, and the anti-shake drive module are three mutually independent modules, so each module is assembled separately and then the three modules are assembled together, which is easier to assemble and can effectively improve the product yield rate. The focusing drive module includes a lens barrel fixed to the lens module, a first bracket accommodating the lens barrel, a focusing coil and a focusing magnetic steel arranged correspondingly, and a first circuit board. The anti-shake drive module includes an image sensor, an anti-shake coil, an anti-shake magnet, and a planar second circuit board in a planar shape to effectively reduce the thickness of the anti-shake drive module and the camera device.
