Wall Display Wire Hanger Structure for Tilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted display devices face difficulties in adjusting viewing angles due to complex and time-consuming mechanisms, and they struggle to securely mount large-sized displays without damaging the wire fixing parts, leading to increased manufacturing costs and a compromised aesthetic appearance.
Innovation Solution
A lifting device for display apparatuses featuring a wire system with VESA holes, rotating arms, and fixing units that allow for easy angle adjustment and secure mounting to a wall, utilizing a wire hanger and anti-separation portions to prevent wire separation and support the display's weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire fixing part is provided at the back cover to fix the wire, then the wire can be mounted to the display apparatus, but the wire fixing part has difficulty in firmly supporting a large-size wall-mounted TV and may be damaged by the weight of the TV
Solution Approach 1:
The wire fixing function is separated from the back cover by using a separate wire hanger component. The back cover includes a wire passing hole for the wire to pass through, while the wire hanger is a detachable component that attaches to the back cover and provides the actual wire fixing capability. This segmentation allows the wire fixing part to be independently designed for strength without compromising the back cover structure.
Solution Approach 2:
The wire hanger acts as an intermediary component between the back cover and the wire. It includes a hook that engages with the wire and a fixing part that attaches to the back cover, distributing the wire's weight and tension forces across a larger area and through more robust attachment points, thereby preventing damage to both the wire and the back cover.
2Adaptability or versatility
If an angle adjustor is provided at the rear surface of the back cover to adjust viewing angle, then viewing angle adjustment is enabled, but adjusting the viewing angle is difficult and time consuming as a viewer must directly rotate upper and lower pivoting parts
Solution Approach 1:
The angle adjustor is designed with a self-adjusting mechanism where the display apparatus can be tilted to the desired angle and then locked in place without requiring the user to manually rotate complex pivoting parts. The mechanism automatically maintains the adjusted position through its structural design, eliminating the need for continuous manual operation.
Solution Approach 2:
Instead of requiring the user to rotate the pivoting parts to achieve angle adjustment, the design allows the display apparatus to be tilted freely and then locked at the desired angle. This inverts the traditional approach by making the locking mechanism passive rather than requiring active rotation of multiple components.
3Ease of manufacture
If the wire of the supporting device is exposed to an area outside of the display apparatus, then the wire can be used to mount the display, but it causes deterioration in an outer appearance
Solution Approach 1:
The wire is nested within the back cover structure by passing through a wire passing hole and being secured by the wire hanger component. This nesting conceals the wire within the boundaries of the display apparatus, preventing it from being exposed to the external environment and thereby maintaining the aesthetic appearance while preserving the mounting functionality.
