Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single endoscope treatment tool is used for multiple treatments, then operational efficiency is improved and tool replacement is reduced, but the tool must be designed with multiple functional components increasing device complexity
Solution Approach 1:
The endoscope treatment tool integrates multiple treatment functions (incision, coagulation, marking) into a single tool by incorporating both first and second monopolar electrodes that can be selectively activated. The switch mechanism allows the operator to choose between different electrode configurations for different treatment purposes, eliminating the need to carry multiple separate tools and improving operational efficiency.
Solution Approach 2:
The tool is segmented into functionally independent electrode components (first monopolar electrode, second monopolar electrode) that can be selectively activated through a switch mechanism. This segmentation allows each electrode to perform specific functions (incision or coagulation) while being part of an integrated multi-functional tool, balancing complexity with versatility.
2Adaptability or versatility
If a high-frequency knife is designed with multiple electrodes for various treatments, then treatment versatility is improved, but the device structure becomes more complex
Solution Approach 1:
The endoscope treatment tool integrates multiple treatment functions (incision, coagulation, marking) into a single tool by incorporating both first and second monopolar electrodes that can be selectively activated. The switch mechanism allows the operator to choose between different electrode configurations for different treatment purposes, eliminating the need to carry multiple separate tools and improving operational efficiency.
Solution Approach 2:
The tool incorporates a switch mechanism that dynamically selects which electrode (first or second) is activated based on the required treatment function. This dynamic configuration allows the same physical tool to adapt its electrical characteristics for different purposes, achieving versatility without permanently complexifying the electrode structure.

AI summary
An endoscope treatment tool can include a sheath, a conductive first rod protruding from a distal end of the sheath, an insulator fixed to a distal end of the first rod, and a conductive second rod extending to a distal side from the insulator. The first rod and second rod are conductive, and the second rod is fixed in a position relative to the insulator along a longitudinal axis of the first rod.
