Movable Extension Assembly for Accessible TV Wall Mount Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall mounting systems for large and heavy flat panel televisions face difficulties in securely fastening the adapter brackets due to the limited space between the television and the wall, making it challenging for installers to access and secure the fasteners, especially with larger screen sizes exceeding 63 inches.
Innovation Solution
The system incorporates a movable extension component connected to a fastener that allows easy access at the bottom of the device mounting bracket, with an extender member and security fastener holder design that secures the device mounting bracket to the surface mounting bracket by sliding fasteners within guide paths and using a security fastener to prevent movement relative to the surface mounting bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adapter bracket is designed to securely attach to the wall mounting plate, then the mounting reliability is improved, but the fastener becomes difficult to access due to the small space between the television and the wall
Solution Approach 1:
The adapter bracket incorporates a movable extension component that can be dynamically repositioned. During installation, the extension is moved to a first position allowing fastener access, and after fastening, it is moved to a second position providing secure attachment. This dynamic repositioning resolves the contradiction between accessibility and security.
Solution Approach 2:
The adapter bracket is segmented into a main body and a movable extension component. This segmentation allows the extension to be independently positioned - extended during installation for fastener access, and retracted after installation for secure mounting. The segmentation enables the bracket to fulfill both accessibility and reliability requirements at different installation stages.
2Stability of the object's composition
If the adapter bracket is designed for secure attachment with fasteners, then the mounting stability is improved, but the installation process becomes more complex due to fastener accessibility issues
Solution Approach 1:
The movable extension component provides a dynamic solution that simplifies installation. The extension can be easily repositioned between extended and retracted states, allowing installers to access fasteners without complex tools or techniques. This dynamic mechanism reduces installation complexity while maintaining mounting stability through secure fastener attachment.
Solution Approach 2:
The movable extension acts as an intermediary between the adapter bracket and the fastener. By extending, it creates an accessible pathway to the fastener; by retracting, it enables secure mounting. This intermediary component mediates between the conflicting requirements of fastener accessibility and mounting stability, simplifying the overall installation process.
3Reliability
If the adapter bracket is designed to prevent movement relative to the wall mounting plate, then the mounting security is improved, but the fastener becomes inaccessible during installation
Solution Approach 1:
The adapter bracket uses a dynamic movable extension that changes position based on installation stage. During installation, the extension is in a first position providing fastener accessibility. After fastening, the extension moves to a second position that prevents movement relative to the wall mounting plate, ensuring mounting security. This dynamic positioning resolves the contradiction between security and accessibility.
Solution Approach 2:
The movable extension is designed to be preliminarily positioned in an extended state during installation to enable fastener access. After the fastening action is completed, the extension is then repositioned to provide secure attachment. This preliminary action of extending the bracket before fastening allows both accessibility during installation and security after installation.

AI summary
An improved system for securing a display device mounting bracket to a surface mounting bracket in a mounting system. A fastener connects to a movable extension component that is movably engaged with the device mounting bracket. When a device mounting bracket has been correctly positioned relative to the surface mounting bracket, the movable extension component is moved until a portion of the surface mounting bracket is positioned between the device mounting bracket and the movable extension component, thereby preventing the device mounting bracket from moving away from the surface mounting bracket.
