Pulsed Diluent Dispenser for Consistent Solid Product Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining the required or desired concentration of a concentrated solution or use solution for solid products over multiple cycles is challenging due to inconsistent dispensing of diluents, such as water, which affects the dissolution process.
Innovation Solution
A dispensing system with a logic device controlling pulsed diluent spray cycles to limit excess diluent in the use solution, ensuring consistent concentration by adjusting variables like diluent volume, pressure, and spray duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If continuous diluent spray is used to dissolve solid product, then dissolution rate is improved, but concentration consistency deteriorates due to excess diluent
Solution Approach 1:
The patent applies periodic action by implementing pulsed spray cycles where the diluent spray is turned on and off at specific intervals. The logic device controls the spray to deliver precise volumes (e.g., 0.5 mL to 5.0 mL per pulse) at defined frequencies, allowing consistent dissolution rates while preventing excess diluent accumulation. This periodic control mechanism maintains both fast dissolution and concentration consistency across multiple dispensing cycles.
2Stability of the object's composition
If pulsed diluent spray is used to limit excess diluent, then concentration consistency is improved, but dissolution rate may deteriorate
Solution Approach 1:
The patent employs parameter changes by systematically adjusting spray volume, spray frequency, and pulse duration to optimize both dissolution rate and concentration consistency. The logic device modifies these parameters dynamically based on pre-programmed sequences, allowing the system to achieve rapid dissolution through higher frequency pulses while maintaining consistent concentration by controlling total diluent volume. This parameter optimization resolves the contradiction between speed and stability.
3Manufacturing precision
If logic device controls spray cycles to pulse diluent, then concentration control is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by programming the logic device with pre-defined spray sequences and volumes that automatically adjust based on dispensing cycle requirements. The system self-regulates the pulsed spray parameters without requiring manual intervention or complex real-time sensing, achieving precise concentration control through automated, pre-programmed control logic. This reduces operational complexity while maintaining high manufacturing precision.
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 pulsed diluent spray effectively increases the concentration of the dissolved solid product in the use solution, maintaining consistency from 3.0 to 10.0% by weight, enhancing the dispensing process for products like enzymes, detergents, and rinse aids.
Implementation Method 1
The diluent contacts a surface of the solid product to dissolve at least a portion of the solid product and create a use solution
Implementation Method 2
The pulsed diluent spray increases the concentration of the dissolved solid product in the use solution by limiting an amount of excess diluent in the use solution during the product dispensing process

AI summary
A dispensing system includes a dispenser, a logic device, a nozzle, a diluent source, and a solid product. The logic device controls spray on and spray off cycles to pulse diluent supplied to the nozzle. The diluent contacts the solid product to dissolve a portion of the solid product and create a use solution. Pulsing the spray of diluent controls the concentration of the dispensed product in the use solution by limiting the amount of excess dilutant added to the dispensed product. The product is more consistently dispensed and the concentration of the dispensed product in the use solution is more consistent. Additionally, the concentration of the dispensed product in the use solution can be controlled by changing at least one of a volume of diluent dispensed through the nozzle, a pressure of diluent, a pulsed diluent spray frequency, and a pulsed diluent spray duration.
