Mounting structure and household appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing foot structures of household appliances, such as refrigerators, require precise installation, which is time-consuming and laborious due to the need for repeated measurements and adjustments, making it difficult for a single person to achieve accurate positioning during installation.
Innovation Solution
A foot structure comprising a base, a first fastener, and a position-limiting block that is rotatable and movable, allowing for precise positioning without manual measurement, with additional features like recessed grooves and snap-fit connections for aesthetics and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the foot structure uses a simple support design, then the device complexity is low, but the installation precision is insufficient requiring repeated measurements
Solution Approach 1:
The position-limiting block is designed to be rotatable around the first fastener axis and movable along the axial direction, transitioning between a protruding state during installation for positioning and a retracted state for aesthetics. This dynamic mechanism enables precise installation positioning without permanently increasing structural complexity.
Solution Approach 2:
The position-limiting block is pre-configured with positioning features (protrusions and corresponding recesses) that automatically engage during the installation process. This preliminary preparation of positioning elements eliminates the need for repeated measurements and adjustments during installation.
2Manufacturing precision
If manual measurement and repeated adjustment are used during installation, then the installation precision can be achieved, but the installation time and labor are excessive
Solution Approach 1:
The position-limiting block automatically performs the positioning function during installation. The protruding block engages with corresponding positioning features on the installation surface, enabling the appliance to self-position without requiring manual measurement or repeated adjustment by the installer.
Solution Approach 2:
The positioning features are pre-designed into the foot structure, allowing the appliance to automatically achieve accurate positioning upon installation without requiring subsequent manual measurement or adjustment operations.
3Ease of operation
If the position-limiting block always protrudes from the base, then the positioning function is always available, but the aesthetic appearance is compromised
Solution Approach 1:
The position-limiting block is designed to rotate around the first fastener axis and move along its axial direction, enabling it to switch between a protruding state (when positioning is needed) and a retracted state (when aesthetics are prioritized). This dynamic capability resolves the conflict between functional visibility and aesthetic appearance.

AI summary
A foot structure for a household appliance comprises a base (202), a first fastener (206), and a position-limiting block (204). A through hole (2022) is arranged at a side wall of the base (202). The position-limiting block (204) is movably connected to the base (202) by means of the first fastener (206). The first fastener (206) partially passes through the through hole (2022) to connect to the position-limiting block (204). The position-limiting block (204) is rotatable around an axis of the first fastener (206), and is movable along an axial direction of the first fastener (206). After rotation of the position-limiting block, the position-limiting block (204) at least partially protrudes from a bottom surface of the base (204).
