Solution Overview
Problem
Existing consumer appliances, such as dishwashing machines, face challenges in selecting the correct personality settings for their control boards, which can be time-consuming, difficult, and prone to errors, especially when a single control board needs to be used across multiple models.
Innovation Solution
A method and apparatus that automatically detect connected electrical elements and select the appropriate personality setting from a plurality of preset personalities, allowing the control board to direct the motor and other components accordingly, eliminating the need for manual selection by the installer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single control board is used across multiple appliance models, then manufacturing cost and complexity are reduced, but the difficulty of correctly selecting the appropriate personality setting increases
Solution Approach 1:
The control board automatically detects the appliance model configuration through electrical element detection and self-configures the appropriate personality setting without requiring manual intervention from the installer. This eliminates the need for installers to manually select personalities while maintaining manufacturing efficiency.
Solution Approach 2:
The system changes operational parameters by detecting the presence or absence of specific electrical elements (such as heaters, pumps, or motors) and automatically adjusting the control board's personality settings to match the detected configuration, thereby adapting to different appliance models.
2Reliability
If manual personality selection is required during installation, then the correct settings can be chosen, but installation time and potential for errors increase
Solution Approach 1:
The control board performs automatic self-detection and selfconfiguration during installation, eliminating the need for manual personality selection. This reduces installation time while maintaining reliability through automated detection of electrical elements that identify the appliance model.
Solution Approach 2:
The system uses feedback from electrical element detection to automatically determine the correct personality setting. The control board monitors the electrical characteristics of connected components and adjusts settings based on this feedback, ensuring accurate configuration without manual intervention.
3Adaptability or versatility
If multiple personalities are programmed into a single control board, then versatility across models is improved, but the complexity of configuring and selecting the correct personality increases
Solution Approach 1:
The control board maintains multiple personalities but uses automatic self-detection to select the appropriate one based on electrical element presence. This preserves versatility across appliance models while eliminating the complexity of manual configuration and selection.
Solution Approach 2:
The control board is designed with universal multi-functionality to support multiple appliance models by detecting electrical elements and automatically configuring the appropriate personality. This allows a single control board design to serve multiple purposes without requiring complex manual setup.

AI summary
A consumer appliance, as provided herein, may include a cabinet, a user interface attached to the cabinet, a motor mounted within the cabinet, and a control board in electrical communication with the user interface and the motor. The user interface may include one or more connected electrical elements. The control board may be configured to initiate an initial operation. The initial operation may include activating the control board and detecting the one or more connected electrical elements from a predetermined plurality of potential electrical elements. The initial operation may further include selecting an operating personality from a plurality of preset personalities based on detecting the one or more connected electrical elements. The initial operation may still further include directing the motor according to the selected operating personality.
