Flow-Regulating Washing Machine Lifter for Uniform Nozzle Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In washing machines, uneven water flow through nozzles on the lifter causes inadequate washing and potential damage to laundry due to inconsistent pressure distribution.
Innovation Solution
The arrangement of barriers around nozzles on the base of the reservoir creates a region for water accumulation, allowing water to gain potential energy and flow into the drum at a consistent rate through each nozzle, ensuring uniform washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is delivered through nozzles on the lifter with high pressure to improve washing efficiency, then washing efficiency is improved, but the laundry gets damaged due to pressure
Solution Approach 1:
The water delivery system is segmented into multiple nozzles distributed across the lifter structure, with each nozzle delivering water at controlled pressure to specific regions of the laundry, preventing concentrated high-pressure damage while maintaining overall washing effectiveness
Solution Approach 2:
The lifter acts as an intermediary structure between the water source and the laundry, incorporating nozzles that regulate and distribute water pressure evenly across the laundry surface, thereby mediating between the need for high-pressure washing and the prevention of laundry damage
2Device complexity
If water flow through nozzles is unregulated to simplify the structure, then device complexity is reduced, but uneven water distribution causes inadequate washing and laundry damage
Solution Approach 1:
The lifter structure is designed with nozzles positioned at equivalent heights and orientations, creating equipotential water delivery conditions that ensure uniform pressure and flow distribution across all nozzles without requiring complex individual regulation mechanisms for each nozzle
Solution Approach 2:
The design optimizes nozzle parameters such as diameter, orientation, and spacing to achieve uniform water distribution through geometric arrangement alone, eliminating the need for complex flow regulation mechanisms and maintaining structural simplicity

Function Achieved in This Case
This solution ensures that water is delivered to the laundry at a consistent flow rate and pressure, improving washing efficiency and preventing damage by ensuring all regions of the laundry are equally washed.
Implementation Method 1
the water accumulates on the base of the reservoir and flows into the drum after gaining a certain potential energy
Implementation Method 2
the water to flow into the drum (4) with a regulated flow as a result of the pressure formed by the accumulation of the water
