Cleaning Appliance Interface for Single-Dose and Bulk Chemistry Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning appliances lack an efficient method to determine whether to use a single use dispensing system or a bulk dispensing system for treating chemistry during a cleaning cycle, leading to potential misuse or inefficiency in chemistry distribution.
Innovation Solution
A method is implemented where a controller in the cleaning appliance selectively controls the dispensing of treating chemistry between a single use system and a bulk system based on user input and sensor feedback, ensuring the appropriate system is used based on the availability and type of treating chemistry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both single use and bulk dispensing systems are provided in cleaning appliances, then the appliance can offer flexibility in chemistry dispensing options, but the complexity of determining which system to use increases
Solution Approach 1:
The system automatically determines which dispensing system to use based on sensor feedback about chemistry availability, eliminating the need for complex user decisions or manual selection mechanisms. The controller autonomously selects between single-use and bulk dispensing based on detected chemistry presence in each system.
2Productivity
If automatic determination of dispensing system is implemented, then dispensing efficiency is improved, but the need for sensors and control mechanisms increases complexity
Solution Approach 1:
The system uses sensors to detect the presence or absence of treating chemistry in both single-use and bulk dispensing systems, providing feedback to the controller. Based on this feedback, the controller automatically determines which system has chemistry available and directs dispensing from that system, enabling efficient automatic operation with minimal complexity.
3Loss of information
If user feedback on dispensing system selection is provided, then user awareness and control are improved, but the interface complexity increases
Solution Approach 1:
The system uses visual indicators such as color-coded lights or display elements to communicate which dispensing system is currently selected or has chemistry available. This provides immediate, intuitive feedback to users about system status without requiring complex interfaces or extensive user education.
