Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional surgical access systems are used, then access to brain abnormalities can be obtained, but compatibility issues with various navigational arrangements and systems occur due to size and material incompatibilities
Solution Approach 1:
The adapter body is designed with a universal interface that can accommodate multiple navigational elements of different sizes and materials. The channel dimensions and locking mechanism are configured to work with various navigational arrangements, making the surgical access system compatible with diverse navigational systems without requiring separate specialized components for each system type.
Solution Approach 2:
The adapter serves as an intermediary component between the surgical access device and different navigational elements. It provides a standardized interface that mediates between the fixed surgical access system and the variable navigational elements, resolving compatibility issues by translating between different navigational element specifications and the surgical access system requirements.
2Reliability
If electromagnetic signal interference is minimized, then navigational system integrity is maintained, but this complicates access to brain tissues
Solution Approach 1:
The adapter is designed with specific material properties and geometric parameters that optimize electromagnetic signal transmission. By carefully selecting materials with appropriate electromagnetic characteristics and configuring the channel dimensions, the adapter maintains navigational system integrity while allowing straightforward access to brain tissues without requiring complex interference mitigation measures.
3Manufacturing precision
If precise alignment is achieved, then surgical precision is enhanced, but this requires complex locking mechanisms
Solution Approach 1:
The locking mechanism is designed to automatically achieve precise alignment and secure the navigational element within the adapter channel. The mechanism self-adjusts to ensure proper positioning through features such as self-centering geometries or elastic recovery, eliminating the need for complex manual alignment procedures or multiple adjustment steps while maintaining high surgical precision.
