Hydraulic Support for Household Appliance Automatic Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance leveling systems, such as those for washing machines, require manual regulation, which is inconvenient and prone to errors, especially with heavy appliances, leading to vibration and noise issues due to instability.
Innovation Solution
A hydraulic-based support system with a flexible accommodation body that automatically adjusts the leveling of household appliances by using a liquid medium to adapt to different pressures, ensuring stable and balanced placement without the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual regulation of leveling devices is used, then the household appliance can be leveled, but user operation is extremely inconvenient and time-consuming
Solution Approach 1:
The patent implements automatic leveling through a hydraulic system where the liquid medium autonomously distributes pressure among multiple support points. The system self-regulates the height of each support leg based on the appliance's actual leveling needs without requiring manual intervention, thereby resolving the contradiction between achieving reliable leveling and maintaining ease of operation.
Solution Approach 2:
The patent replaces the traditional manual mechanical adjustment system with a hydraulic automatic adjustment system. By using liquid pressure transmission instead of manual screw mechanisms, the system achieves automatic leveling that eliminates the inconvenience of manual regulation while maintaining stable leveling performance.
2Reliability
If manual regulation is required for heavy appliances, then leveling can be achieved, but the regulation process becomes extremely inconvenient and accuracy cannot be guaranteed
Solution Approach 1:
The hydraulic system automatically adjusts each support point to achieve optimal leveling accuracy for heavy appliances. The liquid medium distributes weight and adjusts support heights autonomously, eliminating the need for difficult manual regulation while ensuring accurate leveling even for heavy household appliances.
Solution Approach 2:
The patent employs hydraulic principles where a liquid medium transmits pressure uniformly among multiple support points. This hydraulic system automatically compensates for uneven surfaces and adjusts support heights to achieve precise leveling, resolving the contradiction between leveling accuracy and operational convenience for heavy appliances.
3Reliability
If traditional bolt supports are used, then the washing machine can be leveled, but vibration during operation causes supporting failure and out-of-flat placement
Solution Approach 1:
The patent changes the physical state of the support system from rigid mechanical connections to a flexible hydraulic system. The liquid medium can dynamically adjust to vibration forces and maintain stable support heights, preventing vibration-induced supporting failure while maintaining leveling stability during operation.
Solution Approach 2:
By replacing traditional bolt supports with a hydraulic system using liquid medium, the patent creates a more vibration-resistant support mechanism. The hydraulic system absorbs and distributes vibration forces, preventing the supporting failure and out-of-flat placement that occur with rigid mechanical supports during washing machine operation.
4Reliability
If manual leveling regulation is performed, then initial leveling can be achieved, but long-term stability deteriorates due to vibration loosening screws and moving supports
Solution Approach 1:
The hydraulic system using liquid medium provides long-term leveling stability by dynamically compensating for vibration forces. The liquid-transmitted pressure continuously maintains proper support heights without the loosening and instability problems that plague traditional mechanical bolt supports during long-term washing machine operation.
Solution Approach 2:
The automatic hydraulic leveling system continuously self-regulates to maintain stable support heights despite vibration during operation. This eliminates the long-term stability deterioration caused by vibration-induced loosening of manual regulation components, as the hydraulic system requires no manual intervention and automatically compensates for operational disturbances.

AI summary
A support for household appliance includes a hydraulic plate which is fixed to the bottom of the household appliance; a sheath, which is fixedly connected with the hydraulic plate; a regulating support, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating support; and a flexible accommodation body, which accommodates a liquid medium and is arranged in the accommodation chamber. The flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under the action of pressure. The hydraulic plate and the sheath can be rapidly, reliably and fixedly connected, the requirements on the strength of connection between the hydraulic plate and the sheath are lowered, and the essential space and height required by the connection are further lowered.
