Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current siphoning methods are ineffective in non-sealed containers and situations where the fluid surface is not accessible, leading to contamination and disturbance of sediment, and they lack versatility and efficiency across various settings.
Innovation Solution
A peristaltic pump device that can transform into a siphon, featuring a rotary pump with outer rollers and a rotatable cap, allowing for controlled suction and fluid transfer without direct surface access, while maintaining a closed system to prevent contamination and minimizing disturbance of sediment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If differential hydraulic pressure with pumps or oscillation devices is used to initiate siphoning, then the siphoning process can be initiated, but clear access to the fluid surface is required which limits usability in situations where the user lacks a clear line of sight
Solution Approach 1:
The patent introduces a closed system with a movable closure element (valve or flap) that acts as an intermediary to initiate siphoning. This closure element can be actuated from above the fluid surface without requiring direct access to the fluid itself, allowing the user to start siphoning by simply opening the closure element while the system maintains its sealed configuration throughout the process.
Solution Approach 2:
The system is designed to be self-actuating once the closure element is opened. The weight of the closure element itself, combined with the pressure differential created when opening the element, automatically initiates the siphoning flow without requiring external pumps or oscillation devices. The system serves itself by using the closure element's own weight and the pressure differential to start flow.
2Ease of operation
If check valves with oscillating mechanisms are used to initiate a siphon, then siphoning can be initiated, but surface access and sufficient fluid depth are required
Solution Approach 1:
The movable closure element serves as an intermediary that can be opened from above the fluid surface, eliminating the need for direct surface access or oscillating mechanisms. The closure element acts as a simple valve that can be actuated by any means (manual, automated, or remote) without requiring the user to be positioned at the fluid surface or have clear access to it.
3Ease of operation
If pressure is applied to the vessel containing the fluid to initiate the siphon, then siphoning can be initiated, but the vessel must be sealed which limits effectiveness in non-sealed containers
Solution Approach 1:
The movable closure element acts as an intermediary that creates the necessary pressure differential without requiring the entire vessel to be sealed. The closure element can be opened in non-sealed containers to initiate siphoning, and the system maintains its sealed configuration during operation. This allows the same mechanism to work in both sealed and non-sealed containers.
Solution Approach 2:
The closure element's weight and the pressure differential created by opening the element automatically initiate siphoning without requiring external pressure application. The system uses the closure element's own properties and the natural pressure differential to start flow, eliminating the need for external pressurization devices.
4Productivity
If traditional siphoning methods are used, then fluid transfer can occur, but contamination of the fluid and disturbance of sediment may occur
Solution Approach 1:
The closed system with the movable closure element acts as an intermediary that isolates the fluid from external contamination sources. The fluid remains enclosed throughout the siphoning process, preventing contamination from the environment or handling operations. The closure element can be opened and closed without exposing the fluid to contaminants.
Solution Approach 2:
The system uses the closure element's weight and the pressure differential to automatically initiate and maintain siphoning without requiring external intervention that could disturb the fluid. The self-actuating mechanism minimizes handling and intervention, thereby reducing the risk of contamination and sediment disturbance while maintaining efficient fluid transfer.

AI summary
A peristaltic pump for pumping, controlling flow, and siphoning fluid. The pump draws fluid through a tube by using rollers and releases pressure from the tube to form a siphon by opening a bypass door. A rotatable cap provides strength, the ability to rapidly change tubing, as well as locking the bypass door in place for various modes of operation.
