Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing fluid filtration devices are used, then basic filtration function is provided, but versatility for various surgical procedures (suction, irrigation, insufflation) is insufficient
Solution Approach 1:
The device integrates multiple surgical functions (suction, irrigation, insufflation) into a single multi-lumen catheter structure. Different lumens are configured for different functions, allowing one device to replace multiple separate instruments and improve adaptability across various surgical procedures.
Solution Approach 2:
The catheter is divided into multiple lumens (channels) within a single outer tube. Each lumen can be independently configured for specific functions such as suction, irrigation, or insufflation, enabling versatile surgical applications while maintaining a unified device structure.
2Object-affected harmful factors
If conventional filtration devices are used, then simple filtration is achieved, but efficient particle filtration capability is insufficient
Solution Approach 1:
The device incorporates porous filtration media within the catheter structure to achieve efficient particle filtration. The porous material allows fluid passage while trapping particles, providing effective filtration capability without significantly increasing device complexity.
3Productivity
If basic fluid management is provided, then simple fluid handling is achieved, but improved fluid handling capabilities for multiple procedures are insufficient
Solution Approach 1:
The catheter employs multiple separate lumens for different fluid management functions (suction, irrigation, insufflation). This segmentation allows independent control and optimization of each fluid handling function, improving overall productivity and efficiency in surgical procedures.
Solution Approach 2:
The multi-lumen catheter provides universal fluid management capabilities that can handle multiple surgical needs simultaneously. Each lumen is optimized for specific fluid handling tasks, enabling efficient management of complex fluid requirements in various surgical procedures.
