TV Mount Tilt-Swivel Latch Mechanism for Tool-Free Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional television wall mounts lack controlled locking and unlocking mechanisms for tilting and swiveling, making it difficult for users to adjust the viewing angle without tools and often requiring access to bolts located behind the TV, which can be challenging and hazardous.
Innovation Solution
A television mount with an adjustment mechanism that allows tilting and swiveling using a handle to decouple locking members from notches, enabling users to adjust the TV's angle without tools and keeping it locked at desired positions, with features like springs for automatic locking and adapters for various mount types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wall mounts with locking bolts are used, then the television can be securely mounted, but users require tools and difficult access to adjust tilt angles
Solution Approach 1:
The mount is divided into distinct functional modules: a tilt adjustment mechanism with separate locking and unlocking components, a swivel mechanism with independent control, and a mounting bracket portion. This segmentation allows each component to perform its specific function efficiently while maintaining overall system security.
Solution Approach 2:
A handle is introduced as an intermediary component that users can easily grasp and manipulate. The handle transmits user force to the locking members, enabling tool-free operation. This intermediary element bridges the gap between user intent and the mechanical locking system.
2Ease of operation
If locking bolts are positioned behind the television for security, then the mount structure is simplified, but user access to adjustment controls becomes difficult or hazardous
Solution Approach 1:
The adjustment controls are relocated from the traditional behind-TV position to the front-facing surface of the mount. This dimensional relocation allows users to access controls from the front, eliminating the need to reach behind the television and reducing the risk of hand pinching between moving components.
Solution Approach 2:
The mount enables users to independently perform tilt and swivel adjustments without requiring external tools or assistance. The self-contained adjustment mechanism with intuitive controls allows users to service and reposition the television themselves, improving both accessibility and safety.
3Ease of operation
If manual tool-free adjustment is enabled, then ease of operation is improved, but the locking mechanism requires additional components increasing device complexity
Solution Approach 1:
The tilt adjustment mechanism and swivel mechanism are merged into a single integrated mount assembly. Both functions share common structural elements and mounting interfaces, allowing tool-free operation for both adjustments while avoiding the need for separate, redundant locking systems.
Solution Approach 2:
The handle serves multiple functions: it acts as a lever for unlocking the tilt mechanism, a grip for manual tilting, and a control interface for the swivel mechanism. This multi-functionality reduces the need for separate controls for each adjustment type, managing complexity while maintaining ease of operation.

AI summary
A television tilt and swivel device includes a tilt bracket having an arched guide and a plurality of notches, a swivel bracket rotatably coupled to an extender assembly via a swivel rod configured to allow the swivel bracket to swivel in a generally horizontal direction relative to the extender assembly, wherein a lower portion of the swivel bracket is rotatably coupled to a lower portion of the tilt bracket, and wherein an upper portion of the swivel bracket is slidably coupled to the arched guide, a pull latch slidably coupled to the swivel bracket and having a tilt-fixing member configured to fit into one of the plurality of notches and prevent rotation of the tilt bracket, and a biasing element coupled to the swivel bracket and the pull latch, wherein the biasing element is configured to bias the tilt-fixing member toward the plurality of notches.
