Low-Profile TV Tilt Head With Independent Extension Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low profile tilt head mechanisms for thin televisions face challenges in achieving desired tilt angles due to varying mounting hole patterns across different brands, leading to collisions with the wall and limited adjustability, as existing solutions couple tilt motion with extension, restricting the ability to minimize the television's distance from the wall.
Innovation Solution
A tilt head mechanism featuring a base plate and adapter plate connected via scissor assemblies, allowing independent horizontal movement and tilt relative to the mounting surface, decoupling extension and tilt motions to enable precise angle adjustment without horizontal center point displacement, accommodating different television brands' mounting hole patterns.

1Length of stationary object
If a low profile tilt head mechanism is used to reduce the overall thickness, then the device thickness is reduced, but the ability to achieve desired tilt angles is compromised due to the rear bezel striking the mounting surface
Solution Approach 1:
The mounting mechanism is divided into two independent functional segments: a tilt mechanism for angular adjustment and an extension mechanism for distance adjustment. This segmentation allows the tilt function to operate independently from the extension function, enabling the rear bezel to clear the mounting surface during tilting while maintaining a compact overall profile when not in use.
Solution Approach 2:
The invention introduces a third dimension of adjustment by adding extension movement perpendicular to both the mounting surface and the tilt axis. This allows the display device to be moved away from the mounting surface in the horizontal direction, providing the necessary clearance for tilt adjustment without increasing the vertical profile of the mounting mechanism.
2Adaptability or versatility
If the adapter plate center point moves horizontally during tilt, then different brand televisions with varying hole patterns can be accommodated, but the tilt mechanism becomes more complex
Solution Approach 1:
The coupling between tilt and extension motions is segmented and decoupled through independent mechanical mechanisms. The tilt mechanism uses a scissor assembly with guide paths that constrain motion, while the extension mechanism uses a separate scissor assembly. This segmentation allows the adapter plate center point to move horizontally during tilt without requiring a completely redesigned tilt mechanism, as the extension mechanism compensates for the position变化.
Solution Approach 2:
The mounting mechanism transitions from a static, fixed-position design to a dynamic system where the adapter plate center point can move horizontally during operation. This dynamic capability is achieved through the extension mechanism that allows the display device to be moved away from and toward the mounting surface, accommodating different mounting hole patterns while maintaining tilt functionality.
3Device complexity
If tilt and extension motions are coupled, then the mechanism remains simple, but the user cannot minimize the distance from the wall at any given tilt angle
Solution Approach 1:
The single coupled mechanism is segmented into two independent mechanisms: a tilt mechanism with scissor assembly and guide paths for angular adjustment, and an extension mechanism with separate scissor assembly for distance adjustment. This segmentation allows each mechanism to perform its function independently, enabling users to minimize the distance from the wall at any tilt angle by adjusting the extension mechanism without affecting the tilt function.
Solution Approach 2:
The extension mechanism acts as an intermediary between the mounting surface and the tilt mechanism. By allowing the display device to be moved away from and toward the mounting surface, it provides the necessary clearance for tilt adjustment while maintaining a compact overall profile. This intermediary function decouples the tilt and extension motions, enabling independent adjustment.

AI summary
A tilt head mechanism for use with a display device includes a base plate member configured to connect to a vertical mounting structure or surface and an adapter plate member operatively connected to the base plate member. The adapter plate member has a front surface configured to connect to a display device, and the front surface has a center point. The adapter plate member is independently: movable horizontally away from and toward the base plate member; and tiltable downwardly and upwardly relative to the vertical mounting structure or surface, wherein the front surface center point of the adapter plate member does not move substantially horizontally as the adapter plate member is tilted relative to the vertical mounting structure or surface.
