Washing Machine Program Option Filtering for Calibration Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines face issues with non-optimal program sequences due to incorrect load measurements during special programs like calibration, leading to faulty calibration and subsequent suboptimal washing programs.
Innovation Solution
The washing machine's control device is designed to either ignore or account for program options to a lesser extent during special programs, maintaining an optimal sequence by regulating process parameters similarly to washing programs, ensuring accurate calibration and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If program options are allowed to be selected during special programs, then user operation is simplified and interface consistency is maintained, but the special program sequence becomes non-optimal leading to incorrect calibration
Solution Approach 1:
The control device dynamically adjusts its behavior based on the program type. When a special program is detected, the control device enters a mode where selected program options are ignored or applied to a lesser extent. This dynamic switching between full program option application (for washing programs) and restricted application (for special programs) resolves the contradiction by maintaining ease of operation while preserving calibration accuracy.
Solution Approach 2:
The control device acts as an intermediary between the user interface and the program execution. It receives program option selections from the user but filters or modifies their application based on the active program type. This intermediary function allows the interface to remain consistent and user-friendly while preventing harmful modifications to special program sequences, thus resolving the contradiction.
2Adaptability or versatility
If program options are applied during special programs, then the interface appears uniform and functional, but the program sequence becomes non-optimal
Solution Approach 1:
The control device dynamically adapts its processing of program options based on the detected program type. For washing programs, full program option application is enabled. For special programs, the control device switches to a restricted mode where options are ignored or partially applied. This dynamic adaptation maintains interface versatility and consistency while ensuring program sequence reliability.
3Measurement precision
If the control device ignores selected program options during special programs, then calibration accuracy is maintained, but the user may be confused about the functionality
Solution Approach 1:
The control device serves as an intermediary that accepts user inputs (program option selections) during special programs but filters them out before execution. This allows the interface to appear fully functional and responsive, maintaining user understanding and ease of operation, while the intermediary filtering ensures measurement precision and calibration accuracy are preserved.
Solution Approach 2:
The control device creates a virtual copy of the program option selection state for interface display purposes, while the actual execution uses a different state (ignoring the options). This copying approach allows the interface to show uniform functionality without actually applying the options, thus maintaining both user understanding and measurement precision.
