Washing Machine Tangle-Free Agitation Cycle Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washing machine appliances often experience tangling of laundry articles during agitation cycles, which reduces washing efficacy and can cause damage to articles or the wash tub/agitator, necessitating improved methods to prevent or mitigate tangling.
Innovation Solution
A tangle-free option is introduced in the laundry treatment apparatus, allowing users to select a tangle-free mode that adjusts parameters such as water volume, agitator rotational velocity, and movement to reduce tangling, including reducing water volume, agitator speed, and altering the agitator's rotational arc length during the agitation cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional agitation cycle parameters are used (higher water volume, standard agitator speed), then washing efficacy is improved, but tangling of laundry articles increases
Solution Approach 1:
The system dynamically adjusts agitation cycle parameters based on detected load characteristics. The controller modifies water volume, agitator speed, and movement patterns in real-time during the wash cycle to optimize between washing efficacy and preventing article tangling, rather than using fixed traditional parameters throughout the cycle.
Solution Approach 2:
The invention changes physical parameters of the agitation cycle including water volume, agitator rotational velocity, and movement arc length. By adjusting these parameters based on load detection, the system reduces tangling while maintaining effective cleaning performance through optimized parameter combinations.
2Reliability
If agitation cycle parameters are increased to improve washing performance, then cleaning effectiveness is enhanced, but damage to articles and wash tub increases
Solution Approach 1:
The system dynamically adjusts agitation cycle parameters based on detected load characteristics. The controller modifies water volume, agitator speed, and movement patterns in real-time during the wash cycle to optimize between washing efficacy and preventing article tangling, rather than using fixed traditional parameters throughout the cycle.
Solution Approach 2:
The system performs preliminary detection of load characteristics before the agitation cycle begins, and pre-adjusts parameters to prevent excessive mechanical stress on articles and wash tub components, cushioning against potential damage before it occurs.

AI summary
A method of operating a laundry treatment apparatus includes receiving a tangle-free selection signal corresponding to a tangle-free option distinct from a default option, adjusting one or more parameters of an agitation cycle according to the tangle-free option in response to receiving the tangle-free selection signal, and initiating a washing operation incorporating the one or more adjusted parameters.
