Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auxiliary washing machines face limitations in increasing washing capacity due to structural constraints, such as vibration transmission and noise generation, and have difficulty in being installed in narrow spaces while maintaining performance.
Innovation Solution
The design includes a suspension assembly with semispherical recesses and support bars to float the bearing housing, elastic members for shock absorption, and a water supply/drain unit with pivotally connected links to manage vibration and space utilization, enhancing washing capacity and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the auxiliary washing machine is installed below the main washing machine to raise the installation position, then the main washing machine installation position is raised and user convenience is improved, but the washing capacity of the auxiliary washing machine is limited due to narrow space
Solution Approach 1:
The auxiliary washing machine is nested within the stand structure below the main washing machine, utilizing the vertical space efficiently. The drawer-type washing unit is accommodated within the stand's interior space, allowing the auxiliary machine to function within the limited space while the stand provides structural support and vibration isolation.
2Ease of operation
If the washing unit is made separable and drawer-type for ease of maintenance and operation, then ease of operation and maintenance are improved, but vibration transmission to the stand increases
Solution Approach 1:
The stand serves as an intermediary structure between the auxiliary washing machine and the floor. It includes vibration isolation elements such as dampers or elastic members that absorb and reduce vibration transmission from the washing unit to the floor, while still supporting the separable drawer-type construction for ease of maintenance.
3Ease of operation
If the auxiliary washing machine is designed with top loading type for ease of laundry introduction, then ease of operation is improved, but the structure occupies more vertical space reducing installation flexibility
Solution Approach 1:
The auxiliary washing machine uses a drawer-type separable construction that allows horizontal extraction of the washing unit from the stand. This dimensional change from purely vertical space utilization to horizontal accessibility enables top loading operation while maintaining compact vertical footprint for installation flexibility.
