Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate terminals are used to connect the coil to the circuit board, then electrical connection is achieved, but manufacturing complexity and assembly time increase
Solution Approach 1:
The patent merges the terminal function directly into the case structure by forming conductive terminals as integral parts of the case through mold insertion. This eliminates the need for separate terminal components and reduces assembly steps while maintaining reliable electrical connection between the coil and circuit board.
2Reliability
If terminal size is increased to provide sufficient strength, then connection reliability is improved, but device volume increases
Solution Approach 1:
By integrating the terminal directly into the case structure through mold insertion, the patent eliminates the need for additional terminal components that would increase volume. The terminal is formed as part of the case itself, maintaining connection strength while minimizing overall device volume.
3Reliability
If additional terminal components are added, then electrical connection is achieved, but assembly time and labor increase
Solution Approach 1:
The patent combines the terminal function with the case structure, allowing the terminal to be formed as an integral part of the case during the molding process. This eliminates separate terminal components and reduces assembly operations, thereby improving productivity while ensuring reliable electrical connection.

AI summary
A camera module comprises an housing and at least two metal plating layers. The housing comprises a base and two platforms. The base includes a bottom surface, a top surface and an outer wall surface. A receiving hole configured to receive a lens device may be formed in the base, the receiving hole may pass through the base in a direction from the top surface to the bottom surface. The two platforms may be positioned above the top surface of the base and may have different heights. The metal plating layers extends on the outer wall surface of the base. A first end portion of each of the two metal plating layers extends to the top surface of the corresponding platform and the other end portion of the each metal plating layer extends to the bottom surface of the base.
