Washing Machine Support Assembly for Uneven Floor Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washing machines experience vibration and noise due to unstable installation on uneven surfaces, as existing leg adjustment mechanisms are inadequate in compensating for irregular ground levels, leading to poor stability and increased noise during operation.
Innovation Solution
A support apparatus with a first adjustment unit coupled to the base, featuring a guide member and a foot member with a spring and friction mechanism, allowing for both manual and automatic height adjustment to ensure stable installation and reduce vibration through damping functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legs are screw-coupled to the base for height adjustment, then the washing machine can be securely installed on uneven ground, but the structure becomes more complex and assembly becomes more difficult
Solution Approach 1:
The support apparatus is divided into multiple independent units, each comprising a leg, adjustment mechanism, and mounting component. This segmentation allows each unit to function independently for height adjustment while simplifying the overall assembly process and enabling easy replacement of individual units if needed.
Solution Approach 2:
The adjustment mechanism is designed to be user-friendly and self-contained, allowing users to easily adjust the height of each leg independently without requiring complex tools or procedures. The self-service design enables users to compensate for uneven ground conditions themselves during installation.
2Device complexity
If the washing machine is installed on uneven surfaces with fixed legs, then the structure remains simple, but the washing machine experiences severe vibration and noise during operation
Solution Approach 1:
The support apparatus incorporates adjustable legs that can be dynamically modified in length to match the uneven ground surface. This dynamic adjustability ensures optimal contact between the support feet and the ground, minimizing vibration and noise during washing machine operation while maintaining a relatively simple overall structure.
3Reliability
If legs are designed with adjustable height mechanisms, then stable installation is achieved, but the ease of manufacture and assembly is reduced
Solution Approach 1:
The support apparatus is segmented into modular units that can be manufactured separately and assembled easily. Each unit contains its own adjustment mechanism, allowing for standardized mass production of individual components while maintaining the ability to provide stable installation through proper assembly of these standardized parts.
