Solution Overview

Problem

Existing washing machines experience significant vibration and shaking due to the synchronous rotation of the door assembly and tub assembly, leading to collisions during washing or dehydration processes.

Innovation Solution

A washing machine design that includes a support frame with a door support and a tub assembly that rotate synchronously, utilizing a push plate that switches between states to prevent vibration transmission, coupled with sliding shafts and rolling bearings along rail grooves to facilitate smooth rotation and reduce shaking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large amount of detergent is used to ensure complete soil removal, then washing effectiveness is improved, but fabric damage and environmental pollution increase

Engineering Contradiction:

Improvewashing effectivenessVSAvoidfabric damage and pollution

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent employs sensors to detect soil levels, water turbidity, and washing progress, then feeds this information back to the control unit which dynamically adjusts detergent dosage and washing parameters. This closed-loop feedback system ensures optimal detergent usage that achieves complete soil removal while minimizing fabric damage and environmental pollution.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically changes multiple parameters including detergent concentration, water temperature, washing time, and agitation intensity based on real-time detection of soil type and amount. By optimizing these parameters rather than using fixed high doses of detergent, the system achieves effective washing with reduced harmful effects on fabric and environment.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If multiple washing cycles are performed to achieve optimal cleaning, then washing quality is improved, but energy consumption and time usage increase

Engineering Contradiction:

Improvewashing qualityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The patent transforms static, fixed washing programs into dynamic, adaptive washing cycles. The control unit continuously monitors washing conditions and adjusts parameters in real-time, allowing a single adaptive cycle to replace multiple fixed cycles while achieving the same or better washing quality with reduced energy consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system maintains continuous monitoring and adjustment throughout the washing process rather than using discrete separate cycles. Sensors continuously detect soil removal progress and the control unit continuously optimizes parameters, ensuring effective cleaning in one continuous adaptive cycle rather than multiple separate cycles.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If traditional washing methods are used to ensure thorough cleaning, then soil removal is improved, but water consumption increases

Engineering Contradiction:

Improvesoil removalVSAvoidwater consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The system performs preliminary detection of soil type and amount before the washing cycle begins, allowing pre-calculation of optimal water and detergent dosage. This preliminary action enables precise resource allocation that achieves thorough soil removal while minimizing water consumption from the start.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The washing process uses periodic detection cycles where sensors monitor soil removal progress at intervals and the control unit periodically adjusts parameters. This periodic action allows the system to maintain effective cleaning with optimized water usage by only adding water or adjusting parameters when necessary rather than continuously.

Inventive Principle:

Principle #19Periodic action
