Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines require manual adjustment of leveling, which is inconvenient and imprecise, especially for heavy machines, leading to vibration and reduced service life due to unlevel placement and vibration-induced instability.
Innovation Solution
A washing machine hydraulic leveling device with hydraulic feet that communicate through high-pressure oil pipes, allowing for automatic leveling by extending and retracting movable parts driven by hydraulic medium pressure, eliminating the need for manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of bolt feet is used for leveling, then the washing machine can be leveled, but user convenience deteriorates and adjustment precision is low
Solution Approach 1:
The patent replaces the manual mechanical bolt foot adjustment system with a hydraulic control system. The hydraulic feet use liquid pressure to automatically adjust the washing machine's leveling, eliminating the need for manual screwing and turning of bolt feet. This substitution directly resolves the contradiction by providing both ease of operation (automatic control via hydraulic fluid) and high precision (controlled by hydraulic pressure).
Solution Approach 2:
The patent introduces a hydraulic system with hydraulic feet containing hollow chambers filled with hydraulic medium. By controlling the flow and pressure of the hydraulic medium between connected hydraulic feet, the system achieves automatic and precise height adjustment of the washing machine, replacing the inadequate manual mechanical adjustment system.
2Reliability
If the washing machine has large self weight, then the machine structure is stable, but manual height adjustment becomes very inconvenient
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automatic hydraulic control system that can easily handle the washing machine's large weight. The hydraulic feet use liquid pressure to lift and adjust the heavy machine body without requiring user physical effort, thus maintaining machine stability while dramatically improving adjustment convenience.
Solution Approach 2:
The hydraulic system enables the washing machine to perform its own leveling adjustment automatically. By controlling the hydraulic medium flow, the system self-adjusts its position on uneven surfaces without external manual intervention, making the heavy machine easy to level.
3Measurement precision
If bolt feet are used for leveling, then initial leveling can be achieved, but vibration causes support failure and unlevel placement
Solution Approach 1:
The patent uses hydraulic feet with hollow chambers filled with hydraulic medium instead of rigid bolt feet. The hydraulic medium provides continuous adjustment capability and damping effect, allowing the feet to adapt to vibrations during operation while maintaining precise leveling. The connected hydraulic feet can transfer pressure to compensate for vibration-induced position changes.
Solution Approach 2:
The hydraulic system transforms the static bolt foot structure into a dynamic system that can continuously adjust during operation. The hydraulic feet can respond to vibration and load changes by adjusting the position of movable parts through hydraulic pressure, maintaining stable support and precise leveling throughout the washing machine's operation.
4Device complexity
If manual adjustment is required, then device complexity is low, but time and labor are wasted
Solution Approach 1:
The patent introduces a hydraulic control system that dramatically reduces adjustment time. Instead of manually screwing and adjusting bolt feet, the user simply controls the hydraulic medium flow to achieve instant and precise leveling. The added hydraulic components are offset by the elimination of time-consuming manual adjustment operations.
Solution Approach 2:
The hydraulic system enables automatic self-adjustment of the washing machine's leveling position. The system can autonomously respond to height differences and achieve proper leveling without requiring prolonged manual intervention, thus reducing time loss despite increased device complexity.

AI summary
A washing machine hydraulic leveling device comprises hydraulic feet, wherein each hydraulic foot comprises a fixed part and a movable part, a hollow chamber is formed between the fixed part and the movable part, and the hollow chamber is provided with a hydraulic medium; two said hydraulic feet communicate with each other through high-pressure oil pipes: the hydraulic medium flows under pressure between the hollow chambers of the hydraulic feet to drive the movable parts to extend and retract, thereby implementing automatic leveling; and the fixed parts are provided with oil nipples communicating with the hollow chambers, and the oil nipples of the two hydraulic feet are connected to a same connecting piece through the high-pressure oil pipes, thereby implementing communication between the two hydraulic feet.
