Intermediate Dongle Memory for Appliance Control Board Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service professionals face challenges in identifying and selecting the correct personality for replacement control boards in appliances, leading to potential operational failures, and historical data is often lost when the control board is replaced or damaged.
Innovation Solution
An appliance design incorporating an intermediate dongle with a memory device that stores personality settings and historical data, allowing for data transfer between the control board and the dongle, enabling automatic selection of the correct personality and preserving operational history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different personalities are stored on a single substitute control board, then the versatility and adaptability of the control board increases, but the complexity of selecting the correct personality and the risk of incorrect selection increases
Solution Approach 1:
The patent introduces an intermediate dongle as a mediator between the control board and the service professional. The dongle contains a memory device that stores personality information and facilitates automatic identification and selection of the correct personality, eliminating the need for manual selection and reducing complexity while maintaining versatility
2Device complexity
If the service professional is relied upon to know the exact model and choose the correct personality, then the system requires minimal additional components, but the reliability of correct personality selection decreases
Solution Approach 1:
The system implements self-service by enabling the control board to automatically identify the appliance model and select the correct personality through the dongle's memory device. The service professional simply needs to connect the dongle, and the system autonomously handles the identification and configuration process, eliminating human error while maintaining system simplicity
Solution Approach 2:
The patent incorporates feedback mechanisms where the control board queries the memory device in the dongle to retrieve personality information and appliance identification data. This feedback loop ensures the correct personality is selected based on actual appliance characteristics rather than manual input, improving reliability
3Productivity
If historical data is stored on the control board, then the data is readily accessible during operation, but the data is lost when the control board is replaced or damaged
Solution Approach 1:
The patent segments the data storage function from the control board by placing historical data and personality information in a separate memory device within the dongle. This segmentation allows the control board to be replaced without affecting stored data, as the dongle remains external and can be preserved or transferred to a replacement board
Solution Approach 2:
The system creates a copy of the memory device or its contents, allowing the dongle to be retained and reused when replacing control boards. The historical data and personality information are preserved in the dongle's memory device, which can be connected to any replacement control board, preventing data loss while maintaining accessibility
