Dryer Appliance User Interface for Cycle Time Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dryer appliance user interfaces rely on user input for cycle time selection, which can lead to suboptimal drying results due to inaccurate load type or cycle time settings, resulting in overheating or excessive energy consumption.
Innovation Solution
A method that uses a remote user interface device to obtain an image of the drum and load, detect the load type, and determine a recommended incremental cycle time to adjust the base cycle time for optimal drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user selects base cycle time manually, then ease of operation is improved, but manufacturing precision of drying result deteriorates
Solution Approach 1:
The system performs automatic load type detection through image capture and analysis, allowing the dryer to self-determine the appropriate cycle time adjustment without requiring user expertise in selecting the correct drying parameters
Solution Approach 2:
The system provides feedback to the user about the detected load type and the recommended cycle time adjustment, enabling the user to verify the automatic detection results and make informed decisions about the drying cycle
2Reliability
If cycle time is extended for moisture-heavy loads, then drying completeness is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the cycle time parameter based on the detected load type characteristics, extending the cycle time only when necessary for moisture-heavy loads while maintaining optimal timing for other load types, thereby avoiding unnecessary energy consumption
3Use of energy by moving object
If cycle time is shortened for low-moisture loads, then energy efficiency is improved, but drying completeness deteriorates
Solution Approach 1:
The system adjusts the cycle time parameter based on load type detection, shortening the cycle time for low-moisture loads to improve energy efficiency while ensuring the cycle time remains sufficient to achieve complete drying for each specific load type
