Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetically operable valves face challenges in achieving a balance between a large, low-density closure element that can be efficiently accelerated by a magnetic field and restored by flow forces for rapid opening and closing, while maintaining structural stability and minimizing inert mass.
Innovation Solution
A hollow, magnetizable closure element with freely movable magnetizable activator bodies inside, allowing for a low-density design with a large surface area and minimal wall thickness, where the activator bodies are attracted by the magnetic field to move the closure element away from the valve seat, and the flow forces return it due to a small pressure difference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the closure element is made solid and dense to ensure structural stability, then the structural stability is improved, but the acceleration by magnetic field and response time deteriorate due to increased mass
Solution Approach 1:
The closure element is divided into two functional parts: a hollow body providing structural stability and buoyancy, and movable magnetizable activator bodies inside that respond to magnetic fields. This segmentation allows the hollow body to remain stable while the activator bodies enable rapid magnetic actuation with minimal mass.
Solution Approach 2:
The magnetizable activator bodies are nested inside the hollow closure element body. This nesting arrangement allows the activator bodies to be contained within the stable outer structure while remaining free to move and respond to magnetic fields, combining the benefits of structural stability and rapid magnetic response.
2Speed
If the closure element is made hollow to reduce density and mass, then the acceleration by magnetic field is improved, but the structural stability deteriorates due to reduced material
Solution Approach 1:
The hollow body provides buoyant counterweight that compensates for the reduced structural material. This allows the closure element to maintain structural stability despite the hollow design, while the low overall density enables rapid acceleration by magnetic fields.
Solution Approach 2:
The closure element combines a hollow body structure with magnetizable activator bodies inside, creating a composite system that achieves both structural stability and low density for rapid magnetic actuation.
3Stability of the object's composition
If the wall thickness is increased to ensure structural stability, then the structural stability is improved, but the density increases and magnetic acceleration deteriorates
Solution Approach 1:
The closure element is segmented into a thin-walled hollow body for minimal mass and internal magnetizable activator bodies for magnetic response. This segmentation allows the wall thickness to be minimized while maintaining structural stability through the activator bodies and buoyancy.
Solution Approach 2:
The hollow body is designed with minimal wall thickness, utilizing the buoyant force and internal activator bodies to maintain structural stability without requiring thick walls, thereby minimizing mass for rapid magnetic acceleration.
4Force
If the surface area of the closure element is increased to improve flow restoring force, then the flow restoring force is improved, but the volume and mass increase which slows down magnetic acceleration
Solution Approach 1:
The hollow body provides buoyant counterweight that compensates for the increased surface area, allowing the closure element to have large surface area for flow restoring force while maintaining low overall density and mass for rapid magnetic acceleration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design results in rapid reaction times for valve opening and closing, with the low-density hollow body being accelerated effectively by the magnetic field and restored by flow forces, enhancing the valve's operational efficiency and stability.
Implementation Method 1
The magnetizable activator bodies, which are freely movable in the closure element, will be moved by the magnetic field. The activator bodies will be attracted by the wall of the inner chamber and in the process will entrain the entire hollow body
Implementation Method 2
For closing the valve, use is made of the medium flowing through the valve, whose flow forces will carry the closure element back onto the valve seat

AI summary
The invention relates to a valve having a closure element which is movable in an inner chamber and closes or clears a valve seat. The closure element is activated by a magnetic assembly in the magnetizable wall surrounding the inner chamber. According to the invention, the closure element has a low density. It comprises a hollow body having at least one activator body made of magnetizable material that is freely movable therein. The closure element has a low weight and a large surface. The large surface facilitates the resetting of the closure element on the valve seat by the action of the flowing medium.
