Fluid-Driven Chemical Dispensing for Flow-Independent Dilution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical product dispensing systems fail to maintain a consistent concentration of diluted solutions independent of the diluent flow rate, leading to inefficiencies in sanitizing and disinfecting applications.
Innovation Solution
A dispensing apparatus with a housing that includes a product package containing an internally integrated pump, powered by a fluid drive unit, which ensures the rotational motion is transferred to the pump, maintaining a consistent product-to-diluent ratio independent of the diluent flow rate, forming a use solution with a controlled concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional chemical product dispensing system is used, then the system structure is simple, but the concentration of the use solution cannot be maintained consistently independent of the diluent flow rate
Solution Approach 1:
The pump is internally integrated into the product package, with the drive unit connected to the pump shaft. This nested configuration allows the dispensing mechanism to be contained within the product package itself, maintaining precise concentration control while avoiding the need for separate external pumping equipment, thereby reducing overall system complexity.
Solution Approach 2:
The system uses the flowing diluent itself to power the drive unit, which in turn drives the pump to dispense the concentrated chemical product. This self-service mechanism eliminates the need for external power sources or complex control systems, while maintaining consistent concentration through the inherent coupling between diluent flow and product dispensing.
2Manufacturing precision
If a pump internally integrated into the product package is used, then the product-to-diluent ratio is maintained consistently, but the device complexity increases
Solution Approach 1:
The pump, drive unit, and product package are merged into a single integrated assembly. The drive unit is positioned to receive rotational motion directly from the pump shaft, combining the pumping function and drive mechanism into one unified structure that maintains precise product-to-diluent ratio control.
Solution Approach 2:
The pump shaft serves as an intermediary element that directly transmits rotational motion from the drive unit to the pump mechanism. This direct mechanical coupling ensures precise control of the product-to-diluent ratio without requiring complex control systems or intermediate transmission components.
3Manufacturing precision
If volumetric dosing is used to maintain dilution ratio, then the concentration control is improved, but the device complexity and operational complexity increase
Solution Approach 1:
The system automatically maintains the correct dilution ratio by using the flowing diluent to power the drive unit, which in turn drives the pump to dispense the appropriate amount of concentrated product. This self-regulating mechanism eliminates the need for manual dosing controls, sensors, or complex operational procedures, thereby maintaining precise concentration control while ensuring ease of operation.

AI summary
A fluid product dispenser is sized to removably receive a product package containing a supply of the fluid product. The product package includes an internally integrated fluid pump, and the dispenser includes a drive unit powered by flow of a fluid. Flow of the fluid powers the drive unit, which in turn drives the pump internal to the product package, resulting in dispensation of the fluid product in a product/fluid ratio that is independent of the fluid flow rate.
