Dishwasher Cycle Selection for User-Controlled Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers lack user control and monitoring capabilities to optimize energy efficiency based on household-specific variables such as family size, eating habits, and environmental consciousness, as existing technologies do not allow for conscious selection of wash cycles based on energy usage and cleanliness levels.
Innovation Solution
A dishwasher with a control device that directs a series of automatic wash cycles with increasing energy usage levels, allowing users to select subsequent cycles based on a cleanliness evaluation, using an actuator device to adjust energy usage levels according to user preferences and environmental considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the dishwasher provides multiple automatic wash cycles with different energy usage levels, then the user has more control over energy efficiency, but the device complexity increases
Solution Approach 1:
The wash cycles are segmented into a series of automatic cycles with progressively increasing energy usage levels. Each cycle represents a distinct energy efficiency tier, allowing users to select from predefined segments rather than configuring continuous parameters, thus managing complexity while providing adaptability.
Solution Approach 2:
The system changes operational parameters (energy usage level) across the series of automatic wash cycles. By pre-configuring discrete parameter sets rather than allowing continuous adjustment, the system provides user control over energy efficiency while maintaining manageable device complexity through standardized parameter groups.
2Loss of energy
If the user can select subsequent wash cycles based on cleanliness evaluation, then the energy efficiency is optimized, but the ease of operation decreases
Solution Approach 1:
The system enables users to evaluate cleanliness themselves and make informed decisions about subsequent cycle selection. By providing the information needed for users to make their own judgments about dishware cleanliness and energy trade-offs, the system optimizes energy efficiency while maintaining ease of operation through user autonomy rather than complex automated decision-making.
3Loss of information
If the dishwasher monitors and displays energy usage information, then the user can make informed decisions, but the device complexity increases
Solution Approach 1:
The control device provides feedback to users about energy usage levels associated with different automatic wash cycles. This feedback mechanism informs users about the relative energy consumption of each cycle option, enabling informed decision-making without requiring complex monitoring systems, as the feedback is provided through simple, pre-determined energy level classifications.

AI summary
A dishwasher appliance (10) is provided, and includes a control device (102) configured to direct one of a series of automatic wash cycles (200) to be executed by the dishwasher appliance (10). Each successive wash cycle within the series having an increased energy usage level over a previous automatic wash cycle, wherein each energy usage level is determined from at least one operational parameter associated with the respective automatic wash cycle. An actuator device (104) is operably engaged with the control device (102), and is configured to be responsive to the user to select a subsequent automatic wash cycle to be executed by the dishwasher appliance (10) as directed by the control device (102), the subsequent automatic wash cycle comprising one of a previous automatic wash cycle and a successive automatic wash cycle in the series of automatic wash cycles (200), with respect to the one of the series of automatic wash cycles. An associated method is also provided.
