Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If camera modules are miniaturized, then the size of the camera module is reduced, but the parts become more fragile and resistant to external impacts
Solution Approach 1:
The patent integrates the lens barrel directly with the housing to form a unified structure, eliminating separate mounting components. This merging of parts reduces the number of interfaces and potential failure points, thereby improving impact resistance while maintaining miniaturization.
Solution Approach 2:
The patent employs a nested structure where the lens barrel is received within the housing, and the auto-focusing unit is integrated within the lens barrel assembly. This nesting approach maximizes space utilization in miniaturized designs while creating a compact, integrated unit that resists external impacts better than separate components.
2Volume of moving object
If camera modules are miniaturized, then the size of the camera module is reduced, but the assembly difficulty increases
Solution Approach 1:
The lens barrel and housing are merged into a single integrated component, eliminating the need for separate assembly steps to mount the lens barrel. This integration dramatically simplifies the assembly process while enabling miniaturization.
Solution Approach 2:
The housing serves multiple functions: it provides structural support, houses the lens barrel, and integrates the electrode pattern for auto-focusing. This multi-functionality reduces the number of separate parts and simplifies assembly while maintaining compact dimensions.
3Device complexity
If the number of parts is reduced, then the assembly is simplified, but the electric conduction members may be damaged or broken due to external impacts
Solution Approach 1:
The electrode pattern is integrated directly into the housing structure, eliminating separate electric conduction members such as connectors or wires. This integration ensures that the conduction path is structurally protected and cannot be damaged or disconnected, while simultaneously reducing the total number of parts.
Solution Approach 2:
The housing is designed with localized conductive regions (electrode patterns) at specific positions to provide electrical connection. This localized integration of conduction functionality into the structural housing provides both mechanical strength and electrical connectivity without requiring additional vulnerable components.
