Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large image sensor and long focal length lens are used to achieve high-resolution photos, then image quality is improved, but the camera module size increases
Solution Approach 1:
The patent employs a nested lens structure where multiple lens elements are arranged concentrically around a central optical axis. The inner lens structure is positioned within the outer lens structure, creating a compact multi-element lens system that achieves high resolution without proportionally increasing the overall module volume.
Solution Approach 2:
The patent transitions from a traditional linear lens arrangement to a three-dimensional concentric configuration. By utilizing radial and axial dimensions simultaneously, the lens system packs more optical elements into a compact space, reducing the camera module's protrusion while maintaining high imaging capability.
2Volume of moving object
If a compact camera module design is used to maintain terminal thickness, then device compactness is improved, but structural integrity and ESD protection become challenging
Solution Approach 1:
The conductive connector serves multiple functions simultaneously: it provides mechanical connection between the cover frame and camera flange, ensures electrical continuity for ESD protection, and maintains structural rigidity of the camera module. This multi-functionality allows compact design without compromising reliability.
Solution Approach 2:
The conductive connector acts as an intermediary component that establishes an electrostatic discharge path between the external cover frame and the internal camera flange and PCB. This mediator component protects sensitive electronic components from ESD damage while enabling compact module integration.
3Object-affected harmful factors
If conductive connectors are compressed between cover frame and camera flange to enable ESD discharge, then electrostatic protection is improved, but connector reliability may be compromised
Solution Approach 1:
The conductive connector is designed with specific material properties including appropriate hardness, elasticity, and electrical conductivity. By optimizing these parameters, the connector can withstand compression forces while maintaining reliable electrical contact and mechanical connection, ensuring both ESD protection and connection stability.
