Endoscope Closed Space Pumping for Intestinal Waste Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope apparatuses face challenges in efficiently removing large amounts of food residue from the large intestine, requiring repeated fluid supply and suction, which can be inefficient and may not completely remove adherent waste.
Innovation Solution
The endoscope apparatus includes an insertion section with a flow passage that allows a liquid to flow into the object, a closed space forming member to retain the liquid, and a pump to apply pressurization and depressurization to the liquid, facilitating efficient removal of waste by generating a strong water flow within a closed space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated fluid supply and suction is used to remove food residue, then waste removal capability is improved, but cleaning time and fluid consumption increase
Solution Approach 1:
The pump performs repeated pressurization and depressurization cycles on the liquid within the closed space. During pressurization, the liquid flows forward to remove waste; during depressurization, the liquid flows backward. This periodic action intensifies waste removal efficiency compared to continuous unidirectional flow, reducing overall cleaning time while maintaining effective waste removal capability
Solution Approach 2:
The system changes the pressure parameter of the liquid dynamically through pressurization and depressurization cycles. By varying pressure conditions rather than maintaining constant flow, the liquid generates stronger flushing forces that improve waste removal capability while reducing the total time required for cleaning
2Reliability
If repeated fluid supply and suction is used to remove food residue, then waste removal capability is improved, but fluid consumption increases
Solution Approach 1:
The periodic pressurization and depressurization cycles cause the same volume of liquid to flow back and forth multiple times through the closed space. This repeated circulation allows a smaller amount of fluid to achieve the same waste removal effect that would require larger volumes in conventional continuous supply systems, thereby reducing fluid consumption while maintaining effective waste removal
Solution Approach 2:
The liquid remains continuously engaged in waste removal through repeated pressurization-depressurization cycles within the closed space. Rather than supplying new fluid continuously, the system maintains continuous useful action by recycling the same liquid multiple times, improving waste removal capability while minimizing additional fluid consumption
3Productivity
If pump for pressurization and depressurization is added, then waste removal efficiency is improved, but device complexity increases
Solution Approach 1:
The pump serves multiple functions: it pressurizes the liquid to generate forward flow for waste removal, depressurizes to create backward flow for additional cleaning, and controls the timing of these cycles. By making the pump a multi-functional component that performs both pressurization and depressurization, the system improves waste removal efficiency without adding separate components for each function, thereby limiting the increase in device complexity
Solution Approach 2:
The pump acts as an intermediary device that mediates between the fluid supply source and the closed space. Rather than requiring complex separate systems for fluid supply, waste removal, and flow control, the pump intermediates by controlling liquid flow dynamics through pressurization and depressurization, improving waste removal efficiency while keeping the overall device structure relatively simple
