Solution Overview
Problem
Conventional camera modules using VCM technology face challenges in miniaturization and low power consumption, requiring complex electrode connections for actuator control, which complicates the assembly process.
Innovation Solution
The camera module integrates an actuator electrically connected to a substrate, with a conductive pattern on the housing surface for simplified assembly and functional control, eliminating the need for complex connections by forming wiring for each functional control directly on the housing surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional VCM technology is used in camera modules, then the structure is well-established, but miniaturization and low power consumption are difficult to achieve
Solution Approach 1:
The patent merges the actuator substrate with the housing by forming conductive patterns directly on the housing surface. This integration eliminates the need for separate wiring connections between the actuator and PCB, reducing the number of components and simplifying the assembly process while enabling miniaturization
Solution Approach 2:
The housing serves multiple functions: it provides structural support, acts as a conductor for electrical connections, and integrates the wiring function. The conductive pattern on the housing surface serves both as a structural element and as an electrical connection path, reducing overall device complexity
2Volume of moving object
If micro actuators are used for miniaturization, then the camera module size is reduced, but a complex connection process is required to connect electrodes
Solution Approach 1:
The actuator substrate is merged with the housing structure, and the wiring function is merged into the housing surface conductive pattern. This eliminates separate connection components and simplifies the overall structure, allowing miniaturization without increasing connection complexity
Solution Approach 2:
The patent extracts the wiring function from the PCB and relocates it to the housing surface. By forming conductive patterns directly on the housing, the complex electrode connection process is eliminated, and the wiring is integrated into the housing structure itself
3Reliability
If separate wiring connections are required for actuator control, then electrical connection is achieved, but the assembly process becomes complex
Solution Approach 1:
The electrical connection path is merged into the housing structure through conductive patterns formed on the housing surface. This integration maintains reliable electrical connection between the actuator and control circuitry while dramatically simplifying the assembly process by eliminating separate wiring steps
Solution Approach 2:
The housing structure provides its own wiring function through the conductive pattern, eliminating the need for external wiring components. The housing serves itself by providing both structural support and electrical connection functionality, reducing assembly complexity
