Dishwasher Appliance Autonomous Scheduling to Reduce User Involvement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwasher appliances often sit idle for extended periods after completing a wash cycle, requiring user intervention for unloading, which leads to inefficiencies in performance, user comfort, and peak load management.
Innovation Solution
A method of operating a dishwasher appliance that limits user involvement by implementing an operational mode based on user patterns, determining a cycle start time for a current wash cycle, and controlling parameters of subsequent wash cycles based on updated cycle information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dishwasher appliance runs wash cycles based on fixed user schedules, then user comfort is improved by avoiding peak usage times, but the appliance sits idle for extended periods resulting in lost productivity
Solution Approach 1:
The system dynamically adjusts wash cycle scheduling based on real-time detection of user absence and presence patterns. Instead of fixed schedules, the controller continuously learns when the household is away and automatically initiates wash cycles during these periods, optimizing both user comfort and appliance productivity simultaneously
Solution Approach 2:
The dishwasher appliance autonomously determines optimal wash cycle timing by monitoring user patterns and automatically starting cycles when the household is away. This self-service capability eliminates the need for user intervention in scheduling while maximizing appliance utilization without compromising user comfort
2Ease of operation
If the dishwasher appliance requires user intervention to start each wash cycle, then ease of operation is maintained for simple use, but user involvement increases during offline periods reducing autonomy
Solution Approach 1:
The system implements self-service by automatically detecting user absence patterns and autonomously initiating wash cycles without requiring user intervention. The appliance learns from observed patterns and independently makes scheduling decisions, maximizing automation while maintaining ease of operation through simple initial setup
Solution Approach 2:
The controller continuously monitors user presence and wash cycle completion, using this feedback to refine its understanding of absence patterns. This feedback loop enables the system to progressively improve its autonomous scheduling accuracy while requiring minimal user input beyond initial operation
3Ease of operation
If wash cycles are scheduled during peak household usage times, then user convenience is improved by immediate availability, but performance is sacrificed due to overlapping household activities
Solution Approach 1:
The system performs preliminary detection of user absence patterns and proactively schedules wash cycles to start during away periods. By anticipating when the household will be away and pre-scheduling cycles for these times, the system ensures wash cycles run during optimal periods without requiring last-minute user decisions
Solution Approach 2:
The scheduling system dynamically adapts to changing household patterns by continuously learning new absence times and adjusting wash cycle schedules accordingly. This dynamic approach allows the system to maintain optimal scheduling even as household routines change, balancing convenience and efficiency

AI summary
A method of operating a dishwasher appliance to limit user involvement includes receiving, via a user interface of the dishwasher appliance, an indication from a user to start operation of the dishwasher appliance. The method also includes implementing an operational mode for the dishwasher appliance based on one or more user patterns, the operational mode configured to determine a cycle start time for a current wash cycle. Further, the method includes implementing the current wash cycle at the determined cycle start time. After completing the current wash cycle, the method includes updating cycle information stored in at least one of a local memory or a cloud server communicatively coupled to the dishwasher appliance, the cycle information relating to the one or more user patterns. Moreover, the method includes controlling one or more parameters of a subsequent wash cycle of the dishwashing appliance based on the updated cycle information.
