Hydraulic Flexible Support for Vibration-Controlled Washer Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines require manual leveling, which is inconvenient and prone to errors, especially with heavy machines, leading to vibration and noise issues due to out-of-flat placement, causing instability and shortening the service life.
Innovation Solution
A support system with automatic leveling function using a hydraulic medium-filled flexible body assembly that expands and contracts to adjust the washing machine's height, ensuring stability and reducing vibrations and noise through fluid pressure regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual leveling regulation is used, then the washing machine can be leveled, but user operation is extremely inconvenient and time-consuming
Solution Approach 1:
The support system performs automatic leveling adjustment without requiring user intervention. The control system automatically detects the washing machine's leveling state and adjusts the support height accordingly, making the system serve itself rather than requiring external manual operation.
Solution Approach 2:
The patent replaces the traditional manual mechanical adjustment system with an automated control system that uses sensors to detect leveling status and motor-driven mechanisms to adjust support height automatically, eliminating the need for manual screwing and adjusting operations.
2Measurement precision
If manual leveling regulation is used, then the washing machine can be leveled, but regulation accuracy is relatively poor
Solution Approach 1:
The control system continuously monitors the washing machine's leveling state through sensors and uses this feedback information to automatically adjust the support height, achieving precise leveling control without relying on manual user judgment and adjustment.
Solution Approach 2:
The patent replaces imprecise manual leveling judgment with electronic sensors and automated control systems that can detect and adjust leveling status with high precision, eliminating human error in the leveling process.
3Object-affected harmful factors
If the washing machine is not properly leveled, then great vibration is caused during spin-drying, but re-regulation is difficult due to heavy weight
Solution Approach 1:
The support system automatically detects and corrects vibration-causing leveling issues without requiring user intervention, even during or after operation, making the system self-correcting rather than requiring difficult manual re-regulation of heavy equipment.
Solution Approach 2:
The control system performs preliminary automatic leveling adjustment before the washing machine enters operation, ensuring proper leveling is established in advance to prevent vibration problems, rather than requiring post-installation manual adjustment.
4Reliability
If long-term vibration occurs due to out-of-flat placement, then supporting failure is caused, but manual prevention is inconvenient
Solution Approach 1:
The control system continuously monitors and maintains support stability automatically, detecting potential failure conditions and adjusting supports to prevent failure before it occurs, eliminating the need for manual maintenance intervention.
Solution Approach 2:
The system uses continuous feedback from sensors to monitor the washing machine's leveling status and support conditions, automatically making adjustments to maintain stability and prevent supporting failure before it occurs.

Implementation Method 1
a flexible body assembly, which is arranged in the regulating mechanism and accommodates a hydraulic medium; one end of the flexible body assembly is limited and arranged in the sheath, another end is a stretchable end which acts on the regulating mechanism, the stretchable end expands and contracts under the action of the hydraulic medium and drives the regulating mechanism to move axially for automatic leveling

AI summary
A support for washing machine with automatic leveling function comprises: a sheath; a regulating mechanism, arranged in the sheath and axially movable relative to the sheath; and a flexible body assembly, which is arranged in the regulating mechanism and accommodates a hydraulic medium; one end of the flexible body assembly is limited and arranged in the sheath, another end is a stretchable end which acts on the regulating mechanism, the stretchable end expands and contracts under the action of the hydraulic medium and drives the regulating mechanism to move axially for automatic leveling. The flexible body assembly comprises a flexible accommodating body, a mounting, and a protection mechanism between the mounting assembly and the flexible accommodating body. The flexible body assembly is arranged in the sheath to avoid any damage, and the arrangement of the protection mechanism avoids the flexible accommodating body from directly contacting with the mounting assembly.
