Camera Module Recessed Base 3D Circuits Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera modules are limited in miniaturization due to the use of shielding members and connecting pins, which increase production costs and overall height.
Innovation Solution
The camera module design omits the shielding member and connecting pins by incorporating a recessed base with three-dimensional circuits that electrically connect the sensing element and driving mechanism, reducing component count and production costs while enabling miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shielding member and connecting pins are used in conventional camera modules, then electrical connection and shielding are achieved, but the overall height and production cost increase
Solution Approach 1:
The patent merges the shielding member and connecting pins into a single integrated base structure. The base directly provides both shielding functionality and electrical connection through its conductive properties and structural design, eliminating the need for separate shielding members and connecting pins. This integration reduces the overall height while maintaining electrical connection reliability.
Solution Approach 2:
The base is designed to perform multiple functions simultaneously: it serves as a shielding member to protect against electromagnetic interference, as a mounting structure for the lens driving module, and as an electrical connection component through its conductive design. This multi-functionality eliminates the need for separate dedicated shielding members and connecting pins, reducing overall height.
2Reliability
If shielding member and connecting pins are used in conventional camera modules, then electrical connection and shielding are achieved, but production cost increases
Solution Approach 1:
The patent combines multiple components (shielding member, base, and connecting pins) into a single integrated base structure. This reduces the total number of parts that need to be manufactured, procured, and assembled, thereby lowering production costs while maintaining electrical connection reliability through the integrated design.
Solution Approach 2:
The invention extracts and eliminates unnecessary separate components (shielding member and connecting pins) by integrating their functions into the base. This reduction in component count directly lowers material costs, manufacturing complexity, and assembly costs, improving ease of manufacture.
3Reliability
If base thickness is increased to hold connecting pins, then connecting pin retention is improved, but overall height increases
Solution Approach 1:
The patent merges the function of holding connecting pins into the integrated base structure itself. The base incorporates retention features directly in its design, eliminating the need for increased thickness to accommodate separate connecting pins. This maintains connecting pin retention while controlling overall height.
Solution Approach 2:
The invention extracts and eliminates the need for thick base design by removing separate connecting pins. The base thickness is optimized for its primary structural and shielding functions rather than being increased to accommodate separate electrical connection components, thereby reducing overall height while maintaining retention reliability.

Implementation Method 1
The lens driving module 12 is a Voice Coil Motor (VCM), which carries a lens 16 and can move the lens 16 back and forth along an image-capturing optical axis O (parallel to the Z-axis in the figures) by means of a coil, magnets, and a spring sheet
Implementation Method 2
The sensing element 20 can receive a light signal and convert the light signal into an electronic signal

AI summary
A camera module is provided, including a lens holder, a driving mechanism, a frame, a base, a sensing element, and a plurality of three-dimensional circuits. The lens holder carries a lens with an optical axis. The driving mechanism is configured to drive the lens holder along the optical axis. The frame receives the driving mechanism and the lens holder therein. The base supports the frame, and a recess is formed on the bottom of the base. Specifically, the recess is formed by the outer periphery of the bottom of the base extending toward the light-exit direction of the optical axis. The sensing element is disposed in the recess. The three-dimensional circuits are formed in the recess and electrically connected to the sensing element and the driving mechanism.
