Support for household appliance, and household appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance leveling systems require manual adjustment, which is inconvenient and prone to instability, especially for heavy appliances like washing machines, leading to vibration and reduced service life due to unlevel placement and vibration-induced noise.
Innovation Solution
A hydraulic support system with a one-way flow stop mechanism allows for automatic leveling by using a hydraulic medium to adjust the position of the appliance's supports, ensuring stability and reducing noise through controlled fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of bolt supports is used, then the washing machine can be leveled, but the operation is inconvenient and time-consuming for heavy appliances
Solution Approach 1:
The support system performs automatic leveling without human intervention. The hydraulic medium automatically flows between supports to adjust heights, and the one-way flow stop mechanism autonomously prevents loosening, eliminating the need for manual operation entirely
Solution Approach 2:
The manual mechanical screwing operation is replaced by a hydraulic system. Instead of manually turning screw rods, the hydraulic medium flows to automatically adjust support heights, substituting mechanical manual operation with hydraulic automation
2Reliability
If bolt supports are used for heavy washing machines, then the appliance can be supported, but the supports become unstable due to vibration
Solution Approach 1:
The support system uses hydraulic medium instead of mechanical screw rods. The hydraulic medium provides continuous pressure support that is more resistant to vibration loosening, and the fluid can automatically compensate for minor movements to maintain stability
Solution Approach 2:
The support system divides the stabilization function into two independent mechanisms: the hydraulic medium handles height adjustment and support, while the one-way flow stop mechanism handles prevention of loosening. This segmentation allows each component to specialize in its function, improving overall reliability
3Measurement precision
If manual leveling adjustment is performed, then the washing machine height can be set, but precision is relatively low and optimal state cannot be ensured
Solution Approach 1:
The system achieves precise leveling automatically without human intervention. The hydraulic medium naturally flows to equalize pressure across all supports, and the one-way flow stop mechanism precisely controls the flow direction, enabling precision beyond manual capability
