Problem
Existing moving foot bases for furniture are difficult to maneuver, often scratch or damage floors, and lack flexibility to adapt to different weights and sizes.
Innovation Solution
A moving foot base comprising a base body with an accommodating cavity, universal wheels rotatably connected to the base body, and a tray with a limiting plate and latch system to stabilize and protect the floor during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If universal wheels are mounted at the bottom of the base body to enable furniture movement, then the ease of moving furniture is improved, but the floor surface may be scratched or damaged
Solution Approach 1:
The patent implements a movable tray that can switch between a receiving state (when furniture needs to be moved) and a supporting state (when furniture is stationary). This dynamic transformation allows the system to adapt to different operational requirements, enabling easy furniture movement when needed while providing floor protection when the furniture is not being moved.
Solution Approach 2:
The tray serves as an intermediary component between the universal wheels and the floor surface. When in the supporting state, the tray provides a protective interface that prevents direct contact between the wheels and the floor, thereby preventing scratches and damage while still allowing the furniture to be moved when the tray is in the receiving state.
2Object-affected harmful factors
If the furniture is stationary, then floor protection is improved, but a greater pressure is exerted on the floor
Solution Approach 1:
The tray dynamically transforms between receiving and supporting states. When furniture is stationary, the tray transitions to the supporting state, distributing the furniture's weight over a larger area and reducing point pressure on the floor, thereby protecting the floor from both scratches and excessive pressure.
3Adaptability or versatility
If the moving foot base is designed for heavy furniture, then the adaptability to different furniture weights is improved, but the device complexity increases
Solution Approach 1:
The base body and tray structure is designed with multi-functionality to handle various furniture types and weights. The accommodating cavity in the base body can receive different furniture feet, and the tray can switch between receiving and supporting states, making the device universally applicable to different furniture scenarios without requiring multiple specialized components.
Solution Approach 2:
The dynamic transformation mechanism of the tray provides adaptability for different furniture weights and sizes. By switching between receiving and supporting states, the same structure can accommodate various furniture types, reducing the need for multiple specialized devices and thereby managing complexity while maintaining versatility.

AI summary
A moving foot base of furniture comprises a base body, a center of the base body being provided with an accommodating cavity; universal wheels mounted at a bottom portion of the base body, and rotatably connected with the base body; and a tray, the base body and the universal wheels being all arranged on the tray. According to the moving foot base of furniture, a supporting foot of furniture is placed in the accommodating cavity in the base body, and then the universal wheels are mounted at the bottom portion of the base body to realize movement through the universal wheels to move high-mass furniture easily; and the tray is further arranged below the universal wheels, and the tray with a large area loads the furniture to reduce a pressure on a floor caused by the high-mass furniture, thereby avoiding the floor from being damaged.
