Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the optical system size is reduced to meet modern device requirements, then device compactness is improved, but the durability and functionality for auto focus and optical image stabilization deteriorate
Solution Approach 1:
The support assembly is nested within the driving assembly, with the intermediate element positioned inside the first connecting element. This nesting arrangement allows multiple functional components to occupy overlapping spatial volumes, reducing the overall optical system size while maintaining all necessary functions for auto focus and optical image stabilization
Solution Approach 2:
The intermediate element serves multiple functions simultaneously: it acts as a structural support component, a positioning element for the optical element, and part of the driving mechanism for both auto focus and optical image stabilization. This multi-functionality reduces the need for separate components, thereby miniaturizing the system while preserving durability and functionality
2Volume of moving object
If the optical system is miniaturized, then device compactness is improved, but the structural complexity increases
Solution Approach 1:
The driving assembly and support assembly are merged into an integrated structure where the first connecting element and intermediate element form a unified mechanism. This merging reduces the number of separate components and interfaces, simplifying the overall structure despite the miniaturized scale and enabling both auto focus and optical image stabilization functions
