Solution Overview
Problem
Existing household appliance leveling systems require manual regulation, which is inconvenient and prone to instability, especially with heavy appliances, leading to vibration and noise issues due to uneven placement, causing reduced service life and discomfort.
Innovation Solution
A hydraulic-based support system with a flexible accommodation body that automatically adjusts to achieve balance using a fluid medium, featuring a fixing member and protecting member for stability and shock absorption, allowing for adaptive regulation and reduced overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual leveling devices are used, then the household appliance can be leveled, but user operation is inconvenient and time-consuming
Solution Approach 1:
The support system performs automatic leveling through self-adjustment mechanisms. The first support structure automatically adjusts its height based on the unevenness of the placement surface, eliminating the need for manual intervention. The system uses sensors to detect the level state and automatically regulates the support heights to achieve horizontal placement.
Solution Approach 2:
The patent replaces traditional manual mechanical leveling devices with an automated system combining sensors and adjustable support structures. Instead of requiring users to manually rotate lead screws or adjust bolt supports, the system uses automated detection and adjustment mechanisms to achieve leveling.
2Reliability
If traditional bolt supports are used, then leveling is achieved, but the supports are prone to loosening and supporting failure due to vibration
Solution Approach 1:
The support structures are designed with vibration-resistant features and protective elements to withstand the intense vibrations during spin-drying. The system incorporates damping mechanisms and secure fastening arrangements that prevent loosening before vibration damage can occur.
Solution Approach 2:
The patent employs curved or rounded structural elements in the support designs that better distribute vibrational stresses. The curved geometries help reduce stress concentration points that would otherwise lead to loosening and failure under repeated vibration cycles.
3Object-affected harmful factors
If the washing machine is not horizontally placed, then great vibration is caused during spin-drying, but manual regulation cannot guarantee optimum state
Solution Approach 1:
The system incorporates level sensors that continuously monitor the horizontal placement state and provide feedback to the control system. Based on this feedback, the support structures automatically adjust their heights to achieve and maintain optimal horizontal placement, ensuring minimal vibration during operation.
Solution Approach 2:
The patent replaces imprecise manual leveling with automated sensor-based detection and adjustment systems. The electronic leveling system provides higher precision in achieving horizontal placement compared to manual methods, thereby reducing vibration and noise during spin-drying.
4Length of stationary object
If embedding structure is used for fixing member and protecting member, then the overall height is reduced, but the structure becomes more complex
Solution Approach 1:
The fixing member and protecting member are designed with nested or embedded structures where one component is placed within or alongside another. This nesting approach reduces the overall height of the support system while maintaining the necessary protective and securing functions.
Solution Approach 2:
The patent combines multiple functions into integrated components. The fixing member and protecting member are merged into a unified structural arrangement that performs both securing and protective functions simultaneously, reducing the need for separate additional components and simplifying the overall mounting structure.
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 enables automatic leveling, simplifies mounting, reduces vibration and noise, and enhances the stability and service life of household appliances by ensuring balanced placement without manual intervention.
Implementation Method 1
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 action of pressure

AI summary
A control method for opening a door of a drum washing machine comprises the steps: S1, receiving a door opening instruction sent by a user; S2, judging whether a water level at a front end of a drum assembly satisfies a condition of opening the door, if yes, entering step S4, if no, entering step S3; S3, tilting the drum assembly with a tilting mechanism, and then returning to step S2; and S4, unlocking a door lock. Through a manner of lifting a front end of the drum assembly, the operation of opening the door during running is realized. In this way, the original parts of the washing machine do not need to be changed, and the drum assembly is tilted only through a driving device arranged at a lower part of the drum assembly or through a hanging spring arranged at a top part of the drum assembly.
