Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate-component designs are used for optical element driving mechanisms, then assembly stations are complex and manufacturing costs are high, but simplifying the structure may reduce durability and reliability
Solution Approach 1:
The patent integrates the base, supporting elements, and retaining wall into a unified structure. The base includes an integrated body with annular portion and protruding columns, while supporting elements and retaining walls are incorporated as part of the base structure, reducing the number of separate components and assembly stations while maintaining structural integrity and durability
Solution Approach 2:
The base structure serves multiple functions simultaneously: it provides structural support, holds supporting elements for movable portion guidance, incorporates retaining walls for component retention, and integrates coil mounting surfaces. This multi-functionality reduces overall device complexity while maintaining reliability through a consolidated design
2Strength
If traditional heavy-duty structures are used to enhance durability, then impact resistance improves, but device weight and size increase
Solution Approach 1:
The base includes an annular portion with curved geometry that provides structural strength and rigidity while maintaining a compact, lightweight form factor. The curved structure of the annular base distributes stress effectively, enhancing impact resistance without requiring additional heavy materials
Solution Approach 2:
The patent employs magnetically permeable elements (such as ferrite or nickel-based materials) integrated with the base structure, creating a composite system that provides both mechanical strength and magnetic functionality. This composite approach enhances durability and impact resistance while keeping the overall weight minimal compared to solid metal constructions
