Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a lens module is made thinner and more compact, then the device becomes more convenient and portable, but image stabilization and vibration-proofing become more difficult to achieve
Solution Approach 1:
The lens module is divided into multiple independent components: a first lens group, a second lens group, a focusing drive assembly, and an image stabilization drive assembly. Each component performs a specific function, allowing the system to achieve vibration-proofing and focusing capabilities in a compact form factor by distributing functions across segmented modules rather than requiring a single large integrated structure.
2Reliability
If vibration-proofing and zooming functions are added to maintain image quality, then image stability improves, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into an integrated lens module: the first and second lens groups are arranged in sequence along the optical axis to provide both vibration-proofing and zooming capabilities. The focusing drive assembly and image stabilization drive assembly are merged into a single modular structure, reducing overall system complexity while maintaining advanced image quality features.
Solution Approach 2:
The lens module is designed with multi-functionality: the same optical structure serves both vibration-proofing (through the first lens group) and zooming (through the second lens group) functions. The drive assemblies provide both focusing and image stabilization capabilities, allowing a single device to perform multiple optical functions without requiring separate dedicated mechanisms for each function.
