Hydraulic Support for Household Appliances with Automatic Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance leveling systems require manual adjustment, which is inconvenient and prone to failure due to vibration, leading to unlevel placement and reduced service life, especially for heavy appliances like washing machines.
Innovation Solution
A hydraulic support system for household appliances that uses a hydraulic plate, sheath, and regulating element, where the hydraulic medium compresses and expands to drive the regulating element for automatic leveling, ensuring balance and stability through communication between supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of bolt supports is used, then the washing machine can be leveled, but user convenience deteriorates and time is wasted
Solution Approach 1:
The support structure automatically adjusts the washing machine to a level state using the hydraulic medium and regulating element, eliminating the need for manual user intervention. The system self-regulates by allowing the regulating element to move axially in response to pressure changes from the hydraulic medium, achieving automatic leveling.
Solution Approach 2:
The patent replaces the traditional manual mechanical adjustment system with a hydraulic system. The hydraulic medium transmits pressure to the regulating element, which automatically adjusts the support height, substituting manual mechanical operations with hydraulic actuation.
2Reliability
If manual adjustment of bolt supports is used, then the washing machine can be leveled, but adjustment precision is low
Solution Approach 1:
The support structure incorporates a feedback mechanism where the regulating element's axial movement in response to hydraulic medium pressure changes allows the system to automatically sense and correct leveling deviations. The hydraulic medium transmits pressure information that enables precise automatic adjustment to achieve optimal leveling state.
3Productivity
If vibration occurs during washing machine operation, then the washing machine can function, but support stability deteriorates and service life is shortened
Solution Approach 1:
The support structure uses the hydraulic medium and regulating element to provide beforehand cushioning against vibration-induced support failure. The hydraulic system absorbs and dampens vibration effects, preventing loosening of foot screws and vertical movement of the foot bracket that would otherwise occur during long-term operation.
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, reducing vibration and noise, improving appliance stability, and extending the service life by eliminating the need for manual adjustments and addressing the challenges of unlevel placement.
Implementation Method 1
a hydraulic medium, which is in the accommodation chamber and is compressed/expands depending on pressure changes to drive the regulating element to axially move in the sheath for leveling
