Dual-Pulsator Water Flow for Stronger Yet Gentler Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washing machines face challenges in balancing washing force and water efficiency, as strong water streams can damage laundry while excessive water usage increases washing time, making the machines less economical and user-unfriendly.
Innovation Solution
A pulsator device with a first and second pulsator, where the second pulsator is inclined and disposed within a recess of the first, generating a composite stream of water through rotation, reducing laundry damage and water usage by optimizing the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a strong stream of water is generated by the pulsator, then the washing force of the washing machine is improved, but the laundry may be damaged
Solution Approach 1:
The pulsator device is divided into a first pulsator and a second pulsator, each generating water streams independently. The first pulsator generates a strong water stream for effective washing, while the second pulsator generates a separate water stream that combines with the first to reduce the harmful impact on laundry. This segmentation allows the system to achieve both strong washing force and reduced laundry damage simultaneously.
2Quantity of substance
If an amount of water used to wash laundry is increased, then the washing performance is improved, but water supply time and drainage time increase, and total washing time increases
Solution Approach 1:
The two pulsators operate simultaneously to generate water streams that work together continuously throughout the washing process. The first pulsator provides the main washing force while the second pulsator continuously supplies additional water to maintain optimal washing conditions without requiring additional water supply or drainage cycles. This continuous dual-action approach improves washing performance with the same water amount rather than requiring more water and time.
