Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow-interception valves in percolation filtration systems require precise rotational alignment of cartridges to open, making them unreliable due to sensitivity to manufacturing discrepancies and complex valve mechanisms.
Innovation Solution
An enabler element with a holding element and lifting device that grasps and lifts the valve shutter without rotation, using a resiliently deformable portion and a lifting device to move the shutter from a normally-closed position to an open position, ensuring precise and reliable valve opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a combined translation and rotation movement mechanism is used to open the valve shutter, then the valve can be opened, but the device complexity increases and manufacturing precision requirements become more stringent
Solution Approach 1:
The invention separates the valve opening function into two independent components: a holding element that grasps the shutter and a lifting device that provides upward motion. This segmentation eliminates the need for complex combined translation-rotation mechanisms, reducing overall device complexity while maintaining reliable valve opening functionality.
Solution Approach 2:
Instead of using a complex combined movement mechanism to open the valve, the invention inverts the approach by using a simple lifting motion combined with a holding/grasping mechanism. This inversion simplifies the mechanical complexity while achieving the same functional result of reliable valve opening.
2Ease of operation
If a spiral surface coupling mechanism is used between the cartridge and valve shutter, then the valve can be opened, but the manufacturing precision requirements increase significantly
Solution Approach 1:
The invention extracts the complex spiral surface coupling mechanism from the system and replaces it with a holding element that simply grasps the shutter. This extraction eliminates the need for precise spiral surface manufacturing while maintaining the ability to open the valve through a simple lifting motion.
Solution Approach 2:
The holding element with resiliently deformable portion acts as a simple, easily manufacturable component that replaces the precision-critical spiral surface coupling. This disposable-like approach to the holding mechanism reduces manufacturing precision requirements while maintaining operational effectiveness.
3Device complexity
If an abutment-based mechanism is used to move the valve shutter, then the structure is simpler, but the movement precision and reliability decrease
Solution Approach 1:
The invention introduces a holding element as an intermediary between the lifting device and the valve shutter. This holding element grasps the shutter and ensures precise movement during the lifting process, thereby maintaining movement precision while keeping the overall structure relatively simple.
Solution Approach 2:
The holding element changes the interaction parameters between the lifting mechanism and the shutter by providing a grasping connection rather than a simple abutment. This parameter change ensures that the shutter moves precisely during the lifting process without requiring complex mechanism structures.
