Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing anchoring devices are used, then anchoring function is provided, but positioning precision and insertion accuracy are insufficient
Solution Approach 1:
The device is divided into distinct functional modules: a finger-mountable work channel defining assembly with angled axes, an anchor insertion assembly, and an anchor assembly. This segmentation allows each component to be optimized for its specific function while maintaining overall positioning precision without excessive complexity.
Solution Approach 2:
The work channel defining assembly incorporates angled axes (work channel axis angled with respect to finger mounting axis) and an aperture plane at a specific angle, adding dimensional orientation control. This angular geometry enables precise positioning in three-dimensional space while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If existing anchoring devices are used, then anchoring is provided, but versatility in angled orientations and limited axial displacement control is lacking
Solution Approach 1:
The work channel defining assembly is designed with multiple angled axes (finger mounting axis, work channel axis, aperture plane) that can accommodate various anchoring orientations and angles. This multi-functional geometry allows the same device structure to perform diverse anchoring operations at different angles while maintaining ease of operation through a unified design.
Solution Approach 2:
The anchor insertion assembly is configured for limited axial displacement along the work channel axis, providing dynamic control over insertion depth. This controlled mobility allows precise positioning at specific depths while maintaining operational simplicity through guided movement constraints.
3Manufacturing precision
If precise positioning is achieved through angled axes and aperture planes, then anchoring accuracy is improved, but device structure becomes more complex
Solution Approach 1:
The finger-mountable work channel defining assembly integrates multiple positioning functions (finger mounting, work channel definition, aperture positioning) into a single unified structure with predetermined angled axes. This merging of functions reduces the number of separate components needed while maintaining high anchoring placement accuracy through the integrated angular geometry.
