Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance leveling systems require manual adjustment, which is inconvenient and prone to instability, especially with heavy appliances, leading to vibration and noise issues due to out-of-flat placement, causing reduced appliance lifespan.
Innovation Solution
A support system featuring a fixed and moving part with a hydraulic medium in a hollow chamber, connected by high-pressure pipes for automatic leveling, ensuring sealed connections through snap-in connecting members with reinforcing aprons for enhanced strength and stability.
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 device automatically adjusts the household appliance to a leveled state using its own structure and components, eliminating the need for manual user operation. The self-service mechanism resolves the contradiction by making the system independent of user intervention while maintaining effective leveling functionality.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automatic mechanical system comprising a support body, adjustment mechanism, and leveling components that self-regulate. This substitution eliminates the need for user-operated screws and manual positioning, thereby improving ease of operation and reducing time loss.
2Reliability
If manual leveling is performed, then the appliance can be stabilized, but supporting failure is easily caused during long-term use
Solution Approach 1:
The support device incorporates preventive design features that cushion against potential failure modes during long-term use. The adjustment mechanism includes self-locking or self-adjusting components that prevent loosening and maintaining stability throughout the appliance's service life, thereby resolving the contradiction between initial stability and long-term durability.
Solution Approach 2:
The support system transitions from a static manual adjustment to a dynamic self-adjusting mechanism that can compensate for changes in the appliance's weight distribution, settling, or environmental conditions over time. This dynamic capability ensures continuous reliability and extends the support's effective service life.
3Object-affected harmful factors
If the household appliance is out-of-flat, then vibration and noise occur, but manual regulation cannot guarantee optimum state
Solution Approach 1:
The support device incorporates feedback mechanisms that detect the leveling status and automatically adjust the support height to achieve optimal leveling. This closed-loop control ensures high precision in eliminating vibration and noise by continuously monitoring and correcting the appliance's levelness, resolving the contradiction between reducing harmful vibrations and achieving precise leveling.
Solution Approach 2:
The patent replaces imprecise manual leveling with an automatic mechanical system that uses built-in sensors or mechanical indicators to detect levelness and adjusts accordingly. This substitution provides superior measurement precision and consistently achieves the optimum leveled state, thereby minimizing vibration and noise.
4Ease of operation
If bolt supports with lead screws are used, then leveling is achieved, but user operation is extremely inconvenient for heavy appliances
Solution Approach 1:
The support device automatically compensates for the weight of heavy appliances through its self-adjusting mechanism, eliminating the need for users to manually manipulate heavy components or perform difficult manual leveling operations. The system serves itself by detecting and correcting levelness issues regardless of appliance weight, thereby improving ease of operation.
Solution Approach 2:
The patent replaces the manual lead screw and nut gasket system with an automatic adjustment mechanism that uses motors, actuators, or self-balancing components. This mechanical substitution eliminates the need for users to manually rotate screws or adjust heavy supports, making the leveling process convenient even for very heavy appliances.

AI summary
The present disclosure discloses a support for household appliance and a household appliance. The support for household appliance comprises a fixed part and a moving part, a hollow chamber is formed between the fixed part and the moving part and the hollow chamber is provided with a hydraulic medium. At least two household-appliance-used supports communicate with one another through high-pressure pipes; and the hydraulic medium circulates among the household-appliance-used supports under action of pressure to drive the moving part to extend and retract to achieve automatic leveling. Liquid outlet nozzles communicating with the hollow chamber are arranged on the fixed part, the high-pressure pipes are in sealed connection with the liquid outlet nozzles through snap-in connecting members, and the snap-in connecting members have reinforcing aprons which are fit with the fixed part. In the present disclosure, the hydraulic medium circulates between the two supports for the household appliance for automatic leveling.
