Auxiliary Washer Suspension Assembly for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auxiliary washing machines integrated with main washing machines face structural limitations that restrict their washing capacity due to vibration transmission and space constraints, leading to reduced capacity and increased noise and durability issues.
Innovation Solution
The auxiliary washing machine is designed with a suspension assembly that supports the rotating tub to float relative to the drawer, reducing horizontal vibration and noise, and includes a water supply/drain unit with extendable links to prevent damage during withdrawal, enhancing durability and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the auxiliary washing machine is integrated with the main washing machine, then space utilization is improved, but washing capacity is reduced due to structural limitations
Solution Approach 1:
The auxiliary washing machine is divided into independent functional modules: a rotating tub assembly, a suspension assembly, and a drawer assembly. This segmentation allows each component to be optimized independently, enabling the auxiliary machine to achieve sufficient washing capacity within the constrained integrated space.
Solution Approach 2:
The auxiliary washing machine is nested within the main washing machine structure, with the rotating tub positioned inside the drawer assembly. This nested configuration maximizes space utilization while maintaining the washing capacity through efficient spatial arrangement of components.
2Device complexity
If the rotating tub is directly mounted to the drawer, then structural simplicity is improved, but vibration and noise increase
Solution Approach 1:
A suspension assembly is introduced as an intermediary between the rotating tub and the drawer. This suspension assembly includes elastic elements that absorb vibrations generated during washing operations, thereby reducing noise and preventing vibration transmission to the drawer and main washing machine while maintaining structural integrity.
3Volume of stationary object
If the auxiliary washing machine has limited interior space, then integration feasibility is improved, but component installation becomes difficult
Solution Approach 1:
The water supply and drain units are designed with flexible, extendable links that can dynamically adjust their length and position. This dynamic design allows the links to accommodate the limited interior space when the drawer is retracted while enabling easy installation and maintenance access when the drawer is extended, resolving the contradiction between compact integration and component accessibility.
