Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components and specialized assembly are used to accommodate different IOL types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The holder is designed as a universal device that can accommodate multiple types, models, shapes, and sizes of intraocular lenses through a single standardized structure. The base cavity and lid are configured to securely hold various IOL configurations without requiring component changes or specialized assembly procedures, thereby achieving multi-functionality while maintaining manufacturing simplicity
Solution Approach 2:
The holder integrates multiple functional elements into a single unified structure. The base, lid, and sealing components are combined into one molded piece that performs protection, support, and accommodation of different IOL types simultaneously. This merging eliminates the need for separate components and complex assembly operations while maintaining adaptability across IOL varieties
2Adaptability or versatility
If multiple components are used to accommodate different IOL sizes, then versatility is improved, but manufacturing cost increases
Solution Approach 1:
A single holder design serves multiple IOL size requirements through strategically positioned contact points and a configurable cavity structure. The standardized base and lid configuration can securely accommodate various IOL diameters and shapes without requiring different holder models or additional components, achieving versatility while minimizing manufacturing cost through economies of scale
3Adaptability or versatility
If specialized assembly is required for different IOL types, then adaptability is improved, but productivity decreases
Solution Approach 1:
The holder design incorporates discrete, pre-configured elements such as contact points, support structures, and sealing features that are integrated into the molded body. These segmented functional zones allow the holder to adapt to different IOL types through passive geometric compatibility rather than active assembly operations, maintaining productivity while achieving versatility
Solution Approach 2:
The holder structure is designed to automatically accommodate and secure different IOL types through its inherent geometric configuration. The cavity shape, contact point arrangement, and lid closure mechanism work together to self-adjust to various IOL models without requiring specialized assembly procedures, external tools, or operator intervention beyond simple placement and closure
