Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mounting systems for flat-panel televisions are complex, expensive, and offer limited range of motion, stability, and installation difficulties, often requiring professional installation and causing friction and safety issues due to multiple joints and bulkiness.
Innovation Solution
A simplified mounting system comprising a base plate and adapter plate connected by sliding arms that allow translation and rotation, providing a thin profile, easy installation, and reduced friction, with features like cable management and adjustable tilt for improved positioning and glare reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple joints and articulating arms are used to provide range of motion, then the television can be pulled away from the wall and positioned at various angles, but the system becomes extremely complex, expensive to manufacture, and prone to friction and wear
Solution Approach 1:
The mounting system is divided into two independent functional modules: a tilt mechanism for vertical angle adjustment and a rotation mechanism for horizontal orientation. Each module uses a single joint instead of multiple interconnected joints, simplifying the overall system while maintaining full range of motion capabilities
Solution Approach 2:
The patent extracts the articulating arm with multiple joints from the system and replaces it with two separate, simpler mechanisms: a tilt arm for pulling the television away from the wall and a rotation mechanism for horizontal positioning. This eliminates the complexity of three-joint articulating arms while preserving all necessary degrees of freedom
2Adaptability or versatility
If articulating arms with multiple joints are used to permit television to pull away from wall, then positioning flexibility is improved, but friction increases causing plastic components to wear out quickly
Solution Approach 1:
The system segments the motion into two independent rotational movements (tilt and rotation) rather than using a multi-joint articulating arm. Each segment uses a single joint with minimal friction points, eliminating the cumulative friction problem of multiple interconnected joints while maintaining full positioning flexibility
Solution Approach 2:
The patent replaces the mechanical articulating arm system with a simplified mechanism using spring-loaded latches and frictionless pivots. The spring latches provide positioning without continuous friction, and the pivots allow smooth rotation with minimal wear, significantly improving component durability
3Adaptability or versatility
If heavy articulating arms and multiple joints are used to provide full range of motion, then the television can be positioned in various orientations, but the system becomes large, heavy and bulky making installation difficult
Solution Approach 1:
The mounting system is segmented into lightweight, modular components: a base plate, a tilt mechanism, and a rotation mechanism. Each component is independently sized and weighted, eliminating the need for oversized articulating arms. This modular segmentation makes the system compact and easy to install while maintaining full positioning capability
Solution Approach 2:
The patent extracts the unnecessary mass from the system by removing heavy-duty articulating arms and replacing them with lightweight spring-loaded mechanisms. The spring latches and simple pivots provide the same positioning functionality with minimal weight, making installation straightforward for a single person
4Device complexity
If simple mounting systems with limited motion are used, then manufacturing cost is reduced and installation is simplified, but the television has limited range of motion and cannot be rotated
Solution Approach 1:
The patent merges two independent motion capabilities (tilt and rotation) into a single integrated mounting system. The tilt mechanism and rotation mechanism are combined in one compact assembly, providing full range of motion without requiring separate complex mechanisms. This merging achieves versatility while maintaining simplicity through unified design
Solution Approach 2:
The system uses dynamic spring-loaded latches that automatically engage and disengage to permit motion in both tilt and rotation directions. This dynamic mechanism provides unlimited range of motion without requiring complex locking systems or multiple fixed-position joints, maintaining simplicity while enhancing adaptability

AI summary
A system for mounting a flat panel television or display to a surface such as a wall. A base plate is configured to operatively connect to a surface, while an adapter plate is configured to operatively connect to a display device. A plurality of connecting arms are used to operatively connect the base plate to the adapter plate. Each of the plurality of connecting arms includes a base plate engagement portion slidably engageable with slots in the base plate and an adapter plate engagement portion operatively connected to the adapter plate. Movement of the base plate engagement portions within the base plate's slots results in a translational movement of the adapter plate relative to the base plate.
