Solution Overview
Problem
Existing laundry treatment apparatuses face challenges in improving washing performance while minimizing the volume of the laundry accommodation unit, which affects the amount of water and laundry that can be handled.
Innovation Solution
A laundry treatment apparatus design that includes a power transmission unit with a rotating shaft, agitator, and drum configuration, where the agitator and drum are rotated together in the same direction after the agitator has rotated a predetermined number of times, utilizing a stator and rotor for magnetic field generation and a power transmission mechanism with oilless bearings to minimize volume and enhance washing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the volume of the laundry accommodation unit is increased to improve washing performance, then the washing performance is improved, but the volume of the apparatus increases
Solution Approach 1:
The patent applies dynamics by enabling the agitator to rotate independently before the drum rotates, creating a dynamic washing sequence. The power transmission unit allows the agitator to perform a predetermined number of rotations within the drum before the drum itself rotates, optimizing washing performance through controlled motion sequences rather than static configuration alone.
Solution Approach 2:
The patent implements periodic action through the alternating rotation pattern where the agitator rotates for a predetermined number of times, then the drum rotates in the same direction. This periodic sequence of agitator-only rotation followed by combined rotation creates efficient washing cycles that maximize cleaning effectiveness within the compact volume.
