Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing leveling foot structures for household appliances require repeated measurements and adjustments for precise installation, making the process time-consuming and laborious, especially when high precision is needed, and difficult for a single person to implement.
Innovation Solution
A leveling foot structure comprising a base, a first fastener, and a position-limiting block that is rotatable and movable, allowing for accurate positioning without manual measurement, with a spring for automatic restoration and a foot cover plate for aesthetics and protection, facilitating easy installation and firm connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional leveling foot structure is used, then the household appliance can be supported and fixed, but repeated measurements and adjustments are required for precise installation, making the process time-consuming and laborious
Solution Approach 1:
The position-limiting block is pre-configured on the leveling foot structure to define a specific installation position. This preliminary positioning feature eliminates the need for repeated measurements and adjustments during installation, as the block automatically guides the appliance to the correct position when rotated to protrude from the base.
Solution Approach 2:
The position-limiting block serves dual functions: it limits the position of the household appliance during installation and can be rotated to protrude automatically to indicate the correct installation position. This self-service mechanism reduces the need for manual measurement and adjustment operations by the installer.
2Measurement precision
If manual measurement and repeated adjustment are performed for precise installation, then accurate positioning can be achieved, but the installation process becomes difficult for a single person to implement
Solution Approach 1:
The position-limiting block automatically performs the positioning function by being rotated to protrude from the base, eliminating the need for manual measurement and adjustment operations. This self-service mechanism makes the installation process easy to implement even for a single person, as the block guides the appliance to the correct position without requiring complex manual operations.
3Measurement precision
If the position-limiting block is rotatable and movable, then accurate positioning is achieved, but the structure becomes more complex
Solution Approach 1:
The position-limiting block is integrated with the leveling foot structure, combining the positioning function with the existing support and adjustment mechanisms. This merging approach adds the positioning capability without requiring a completely separate complex system, as the block utilizes the existing base and fastener structure of the leveling foot.
Solution Approach 2:
The position-limiting block serves multiple functions: it limits the position of the household appliance, can be rotated to protrude to indicate the correct installation position, and can be adjusted along with the leveling foot. This multi-functionality reduces the need for additional separate components, thereby minimizing the increase in overall structural complexity.

AI summary
A leveling foot structure for a household appliance comprises a base, a first fastener, and a position-limiting block. A through-hole is arranged at a side wall of the base. The position-limiting block is movably connected to the base by means of the first fastener. The first fastener partially passes through the through-hole to connect to the position-limiting block. The position-limiting block is rotatable around an axis of the first fastener, and is movable along an axial direction of the first fastener. After rotation of the position-limiting block, the position-limiting block at least partially protrudes from a bottom surface of the base.
