Engineering Contradiction Analysis
1Reliability
If conventional electrical connections using cables or flexible printed circuit boards are used, then the image sensor can be electrically connected to the compact camera module, but the device complexity and product size increase
Solution Approach 1:
The patent merges the electrical connection function directly into the lens barrel structure by integrating a circuit board within the lens barrel that electrically connects to the image sensor. This eliminates the need for separate cables or flexible printed circuit boards, thereby reducing device complexity while maintaining reliable electrical connections between the compact camera module and the image sensor.
2Reliability
If encapsulating material is used to assemble the compact camera module and image sensor, then the assembly is protected, but the process costs and product size increase
Solution Approach 1:
The patent integrates the electrical connection structure directly within the lens barrel assembly, eliminating the need for separate encapsulating materials to protect external connections. The circuit board is housed within the lens barrel itself, providing inherent protection without requiring additional encapsulation steps, thereby reducing manufacturing complexity and cost.
3Reliability
If external circuit boards and cables are used for electrical connections, then the image sensor can be connected to the compact camera module, but the product size becomes larger
Solution Approach 1:
The patent consolidates the electrical connection components within the lens barrel structure by integrating a circuit board that is housed inside the lens barrel. This internal integration eliminates the need for external cables and separate circuit boards, significantly reducing the overall product size while maintaining reliable electrical connections between the compact camera module and the image sensor.
4Reliability
If conventional assembly methods with multiple components are used, then the compact camera module can be assembled, but the assembly process becomes more complex and yield decreases
Solution Approach 1:
The patent integrates the circuit board and electrical connection components directly within the lens barrel assembly, reducing the number of separate parts and assembly steps. This integration simplifies the manufacturing process, reduces assembly complexity, and improves production yield by eliminating multiple connection points and reducing the risk of assembly errors.
