Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing and dosing elements for heavy mediums with high solid abrasive particles suffer from rapid damage to sliding and moving parts, leading to high maintenance costs and production disruptions due to abrasive wear.
Innovation Solution
A flexible pushing-dispensing and/or dosing element with a flexible insert that changes volume to push and expel medium, featuring a through-hole with a one-way valve to minimize exposure to abrasive particles, using a pushing pin that moves between positions to control the medium's flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sliding and moving parts are used in dispensing elements for CHFC, then the dispensing element can be precisely coupled for accurate dosing, but the abrasive solid particles cause excessive wear and damage in a very short time
Solution Approach 1:
The invention extracts and eliminates the problematic sliding and moving parts from the dispensing element. The flexible membrane dispense element is designed without any sliding or moving parts that contact the CHFC medium, thereby removing the source of abrasive wear while maintaining dosing functionality through elastic deformation of the membrane
Solution Approach 2:
The invention replaces the traditional mechanical sliding and moving parts with an elastic membrane system. The flexible membrane uses elastic deformation to achieve dosing and dispensing functions without mechanical contact between moving parts, substituting a wear-prone mechanical system with an elastic deformation-based system that is resistant to abrasive wear
2Manufacturing precision
If sliding and moving parts are used in pushing-dispensing elements, then the element can be precisely coupled for accurate medium delivery, but the abrasive particles cause the pushing element to get stuck or excessive play in a very short time
Solution Approach 1:
The invention removes all sliding and moving parts from the pushing-dispensing element, eliminating the components that would get stuck or develop excessive play due to abrasive wear. The flexible membrane design achieves precise medium delivery through elastic deformation without mechanical sliding contacts
Solution Approach 2:
The invention employs a flexible membrane shell that deforms elastically to control medium flow. This flexible structure replaces rigid sliding and moving parts, allowing precise delivery control through membrane deformation while avoiding the sticking and wear problems associated with traditional mechanical components
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
The solution reduces wear and tear by minimizing the number of sliding parts exposed to abrasive media, ensuring consistent and controlled dispensing with reduced maintenance needs and operational efficiency.
Implementation Method 1
said flexible insert which remains essentially non deformed during pumping of said medium, preferably CHFC from its reservoir... into a compression volume... said pushing-dispensing and/or dosing element deformed during pushing of said pushing means preferably pushing pin acting onto the upper flange of pushing-dispensing and/or dosing element in such a way that through hole is narrowed and due to decrease of internal volume pushes predetermined quantity of medium
Implementation Method 2
lifting of pushing means preferably pushing pin in direction from flexible insert which, due to resulting vacuum, said vacuum referring to pressure lower then pressure in said reservoir, pumps in a medium, preferably CHFC , from a reservoir

AI summary
A pushing-dispensing and/or dosing element for dispensing of medium, in particular Composite Heavy Fluid Compound (CHFC) or plurality thereof solves technical problem of implementation of a pushing-dispensing and/or dosing element that will not have sliding and/or moving parts, or it will have a limited number of said sliding and/or moving parts essentially exposed to medium, preferably CHFC, or plurality thereof by using a flexible cartridge that behaves differently during the pushing of CHFC, and differently during pumping of said CHFCs out of the tank in which they are held.
