Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If simple mechanical devices are used, then manufacturing cost is reduced, but gripping effectiveness deteriorates
Solution Approach 1:
The extractor is divided into modular components including a handle, extractor body, and interchangeable extraction devices that can be separately manufactured and assembled. This segmentation allows simple manufacturing of individual parts while maintaining overall gripping effectiveness through proper component integration.
Solution Approach 2:
The extractor body is designed with universal features including multiple transverse openings that can accommodate different extraction devices for various implant types. This multi-functionality allows a single base design to serve multiple purposes, reducing overall manufacturing complexity while maintaining gripping effectiveness across different applications.
2Reliability
If complex mechanical devices are used, then gripping effectiveness is improved, but device complexity increases
Solution Approach 1:
The extraction devices are designed as separate, removable components that can be independently optimized for specific gripping functions. By extracting the complex gripping mechanisms from the main body and making them interchangeable, the overall device complexity is reduced while maintaining high gripping effectiveness through specialized extraction device design.
Solution Approach 2:
The extractor incorporates adjustable features including movable extraction devices that can be positioned at different angles and depths, and interchangeable components that allow adaptation to various implant configurations. This dynamic adjustability provides gripping effectiveness for different scenarios without requiring multiple specialized devices.
3Reliability
If complex mechanical devices are used, then gripping effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The extractor features self-aligning and self-adjusting mechanisms that reduce the skill level required for operation. The interchangeable extraction devices automatically position themselves through simple insertion, and the design includes intuitive features that guide proper placement, making effective operation accessible to users with varying levels of expertise.
Solution Approach 2:
The extraction devices are pre-configured with specific geometries and engagement features that automatically align with corresponding features on the extractor body upon insertion. This preliminary preparation of the components eliminates complex adjustment steps during surgery, improving ease of operation while maintaining gripping effectiveness.
