Wall-mounted structure and electronic device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted structures for electronic devices, such as flat panel TVs and photo frames, require users to remove and re-install the device to change display orientations, which is inconvenient.
Innovation Solution
A wall-mounted structure comprising a wall-mounted plate with a limiting block and a connecting plate featuring sliding surfaces, allowing the connecting plate to rotate relative to the wall-mounted plate in a plane parallel to the plate body, enabling easy adjustment of display states without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed connecting structure such as a bracket or connecting rod is used to mount an electronic device on a wall, then the device can be securely fixed, but the user cannot easily change the display orientation without removing and re-installing the device
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connecting structure into a dynamic one with sliding surfaces. The limiting block on the wall-mounted plate has a first sliding surface, and the limiting plate on the connecting plate has a second sliding surface that contacts the first sliding surface, allowing the connecting plate to slide and rotate relative to the wall-mounted plate, enabling easy orientation changes while maintaining secure mounting
Solution Approach 2:
The patent segments the connecting structure into two independent parts: a wall-mounted plate with a limiting block and a connecting plate with a limiting plate. This segmentation allows each part to be optimized independently and enables relative movement between them through the sliding surfaces, solving the contradiction between secure fixation and easy repositioning
2Adaptability or versatility
If a fixed connecting structure is used to mount an electronic device, then the installation is simple and stable, but the user must remove the device to change display states
Solution Approach 1:
The dynamic sliding mechanism allows the connecting plate to move along the arc-shaped first sliding surface of the limiting block, enabling the user to switch between horizontal and vertical display states by simply sliding the connecting plate without removal, thus eliminating re-installation time while improving adaptability
Solution Approach 2:
The sliding surfaces act as an intermediary mechanism between the fixed wall-mounted plate and the movable connecting plate. This intermediary allows controlled movement and orientation change while maintaining the connection, enabling quick adaptation without complete disassembly and reassembly
3Ease of operation
If sliding surfaces with arc shapes are provided on the limiting block and limiting plate, then the connecting plate can rotate relative to the wall-mounted plate, but the manufacturing complexity increases
Solution Approach 1:
The patent uses arc-shaped sliding surfaces instead of flat surfaces. The first sliding surface on the limiting block and the second sliding surface on the limiting plate are both arc-shaped, allowing the connecting plate to rotate smoothly relative to the wall-mounted plate. While curved surfaces are slightly more complex to manufacture than flat surfaces, they enable the desired rotational movement functionality

AI summary
The wall-mounted structure includes a wall-mounted plate fixable on a wall and a connecting plate connectable to an electronic device. The wall-mounted plate includes a plate body and a limiting block on a top end surface of the plate body provided with a first sliding surface extending in an arc shape. The limiting block is provided with a first limiting surface connected to the first sliding surface. The connecting plate includes a limiting plate. The limiting plate is provided with at least a bottom end surface and two main surfaces connected to two sides of the bottom end surface. The bottom end surface is a second sliding surface extending in an arc shape. One of the main surfaces of the limiting plate is a second limiting surface connected to the second sliding surface. The second limiting surface extends from one end of the limiting plate to the other end of the limiting plate.
