Bulk Dispensing Interface for Remaining Dose and Chemistry Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bulk dispensing systems in household cleaning appliances lack a method to accurately determine and indicate the number of doses and types of treating chemistry available, leading to user ambiguity and inconvenience.
Innovation Solution
A method that utilizes sensors and a controller to determine the number of doses and types of treating chemistry in a bulk dispensing system, providing this information on a user interface, allowing for clear communication to the user about the remaining doses and types of chemistry available for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bulk dispensing system is used to reduce refilling frequency, then convenience is improved, but user awareness of remaining doses and chemistry types deteriorates
Solution Approach 1:
The system implements feedback by providing visual indicators (LED lights or display screen) that show the number of doses remaining and the type of chemistry in the bulk dispensing system. This allows users to monitor the dispensing system status without manual intervention, resolving the information loss while maintaining bulk dispensing convenience.
Solution Approach 2:
The controller acts as an intermediary between the bulk dispensing system and the user. It processes information about remaining doses and chemistry types, then presents this information through the user interface in a comprehensible format, bridging the gap between the automated system and user awareness.
2Ease of operation
If bulk dispensing system is implemented, then refilling frequency is reduced, but system complexity increases
Solution Approach 1:
The controller serves multiple functions: it controls the dispensing mechanism, monitors remaining doses, identifies chemistry types, and manages the user interface. By consolidating these functions into a single control unit, the system achieves bulk dispensing capability without proportionally increasing overall system complexity.
Solution Approach 2:
The bulk dispensing system is designed to automatically track and report its own status (remaining doses and chemistry types) without requiring user intervention or external monitoring systems. This self-service approach reduces the need for additional complex components while achieving the refilling reduction benefit.
3Device complexity
If no indication system is provided, then device complexity is reduced, but user convenience deteriorates
Solution Approach 1:
The system uses color-coded LED indicators or display elements to communicate the status of the bulk dispensing system. Different colors or patterns indicate different numbers of remaining doses or chemistry types, providing intuitive visual feedback that enhances user convenience without requiring complex interface hardware.
