Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems for soluble solid substances fail to maintain a balanced concentration and stable quality of the solution over time, leading to inconsistent cleaning solutions in professional ware-washing machines.
Innovation Solution
A dispensing system with a circulation line and circulation pump that continuously or intermittently circulates the solution through a circulation line, ensuring a balanced concentration and stable quality by controlling the spraying of solid substances with water, measuring conductivity, and adjusting the operation of pumps and valves via an electronic control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If solid substance concentrate is used for storage and transportation, then volume and weight are saved, but the substance must be brought into solution before use which requires additional devices and processes
Solution Approach 1:
The invention extracts the dissolution function from complex mechanical devices and transfers it to the fluid dynamics of the dispensing system itself. The spray nozzle creates a mist that naturally dissolves the solid concentrate during the dispensing process, eliminating the need for separate dissolution chambers, agitation mechanisms, or heating elements.
Solution Approach 2:
The system uses its own dispensing operation to accomplish dissolution. The spray mist generated during normal dispensing serves dual purposes: delivering the cleaning solution and simultaneously dissolving the solid concentrate in the reservoir, making the system self-sufficient without external dissolution equipment.
2Object-affected harmful factors
If solid substance concentrate is stored remotely in a dispensing system, then health risks are avoided, but the solution concentration and quality become unstable over time
Solution Approach 1:
The system maintains continuous or periodic spraying action that constantly dissolves fresh solid concentrate and mixes it into the solution reservoir. This continuous action prevents concentration stratification and degradation, ensuring stable solution quality over time while keeping the hazardous solid concentrate sealed in the remote reservoir.
Solution Approach 2:
The system incorporates sensors that monitor solution properties and provide feedback to the control unit, which adjusts the spraying rate and duration to maintain optimal concentration levels. This closed-loop control ensures consistent solution quality despite variations in temperature, usage patterns, or reservoir levels.
3Ease of operation
If spray means is used to dissolve solid substance, then the substance is brought into solution, but the concentration balance and solution quality deteriorate over time
Solution Approach 1:
The system dynamically adjusts the spraying parameters including mist fineness, spray duration, and spray intensity based on real-time feedback from sensors. This dynamic control optimizes dissolution efficiency while preventing over-spraying that could cause concentration imbalance or foam formation, maintaining solution quality throughout operation.
