Solution Overview
Problem
Existing household appliance leveling systems, such as those for washing machines, require manual adjustment and are inconvenient, especially with heavy appliances, and can lead to instability and increased noise due to vibration, causing premature wear and discomfort.
Innovation Solution
A hydraulic-based support system with a flexible accommodation body that uses a liquid medium to automatically level appliances by circulating fluid through a liquid flow passage and regulating support, ensuring balanced positioning and reduced vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual leveling devices are used for heavy household appliances, then the appliance can be leveled, but user operation becomes extremely inconvenient and time-consuming
Solution Approach 1:
The patent implements automatic leveling through a hydraulic system that self-regulates the appliance position. The flexible accommodation body with liquid medium automatically adjusts the support height in response to uneven surfaces, eliminating the need for manual intervention while maintaining reliable leveling stability.
Solution Approach 2:
The patent replaces the traditional manual mechanical leveling system (lead screw, nut gasket, rubber pad) with a hydraulic system. The flexible accommodation body filled with liquid medium uses hydraulic pressure to automatically adjust and maintain the appliance at the correct level, substituting complex manual mechanical operations with fluid-based automatic adjustment.
2Reliability
If manual regulation is performed on heavy appliances, then leveling can be achieved, but the process consumes excessive time and labor
Solution Approach 1:
The hydraulic leveling system operates autonomously to achieve accurate leveling. When the appliance is placed on uneven surfaces, the flexible accommodation body automatically adjusts its volume and position through liquid pressure, achieving precise leveling without requiring user time or effort for regulation.
Solution Approach 2:
The flexible accommodation body is pre-filled with liquid medium and positioned to automatically respond to surface irregularities. This preliminary preparation allows the system to instantly self-correct any leveling issues upon placement, eliminating the time-consuming manual adjustment process while ensuring accurate leveling.
3Strength
If traditional bolt bottom feet are used, then the appliance can be supported, but vibration during operation causes loosening and instability
Solution Approach 1:
The patent employs a flexible accommodation body instead of rigid bolt bottom feet. This flexible structure can dynamically absorb and adapt to vibrations during appliance operation, maintaining stable support while resisting the loosening effects that plague traditional rigid mechanical fastening systems.
Solution Approach 2:
The hydraulic system using liquid medium provides continuous, stable support that is inherently resistant to vibration-induced loosening. The incompressible nature of the liquid ensures consistent pressure and support force even during high-vibration operations like spin-drying, maintaining reliability where traditional mechanical systems fail.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hydraulic support system simplifies leveling, enhances stability, reduces noise, and extends the lifespan of appliances by automatically adjusting to uneven surfaces, eliminating the need for manual intervention and minimizing vibration-induced damage.
Implementation Method 1
a liquid medium arranged in the flexible accommodation body circulates under the action of pressure into a liquid flow passage internally provided in a hydraulic plate
Implementation Method 2
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

AI summary
A support for household appliance comprises a hydraulic plate internally provided with a liquid flow passage, a sheath fixedly connected with the hydraulic plate, a regulating support arranged in the sheath and axially movable relative to the sheath, an accommodation chamber is formed by the hydraulic plate, the sheath and the regulating support. A flexible accommodation body that accommodates a liquid medium in the accommodation chamber extends and retracts to drive the regulating support to move in the sheath for leveling under the action of pressure. The flexible accommodation body is provided with an mounted on the hydraulic plate through the sheath in a sealed manner and communicates with the a liquid flow passage. The hydraulic medium in the flexible accommodation body can circulate into the liquid flow passage and flow to the liquid outlet nozzle through the a liquid flow passage, and thus, among household-appliance-used bottom feet for automatic leveling.
