Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple sutures and needles are manipulated manually for anastomosis of small tubular organs, then the anastomosis can be completed with basic surgical tools, but the procedure becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple suturing functions into a single integrated device. The anastomosis device incorporates multiple needles, suture threads, and manipulation mechanisms into one unified tool, allowing simultaneous or coordinated suturing actions that would otherwise require separate manual operations, thereby increasing procedure speed while managing complexity through integration
Solution Approach 2:
The device employs dynamic mechanisms including rotatable components for positioning needles, movable suture guides, and adjustable coupling members that can rotate relative to each other. These dynamic elements allow the device to adapt its configuration during the anastomosis procedure, enabling efficient manipulation of multiple sutures without requiring complex manual repositioning of separate tools
2Loss of time
If a streamlined anastomosis approach is implemented using integrated coupling members, then procedural time is reduced, but the device structure becomes more complex
Solution Approach 1:
The device is divided into distinct functional modules: first and second coupling members that can rotate independently, each with their own needle channels and suture management systems. This segmentation allows each module to perform specific functions efficiently, reducing overall procedural time while organizing complexity into manageable, independent components that can be manipulated separately
Solution Approach 2:
The coupling members are designed to perform multiple functions: they guide needles, manage suture threads, enable rotation for positioning, and facilitate the anastomosis of tubular organs. This multi-functionality reduces the need for multiple separate tools or steps, thereby decreasing procedural time while consolidating functions into integrated structures
