Angular Position Locking Bracket for TV Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall tilt systems for flat-panel televisions lack a secure mechanism to lock the angular orientation, leading to accidental movement due to friction-based mechanisms that do not definitively fix the position, especially in residential and commercial settings where adjustments are infrequent.
Innovation Solution
An incremental angular position and locking system where an adapter bracket with angular positioning portions and a locator portion is slidably or rollingly engaged with a tilt bracket, allowing users to securely fix the orientation using a locking member, enabling precise and stable positioning of attached devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If friction-based mechanisms are used to control resistance and maintain angular orientation, then ease of operation is improved, but reliability deteriorates due to inability to definitively lock the position
Solution Approach 1:
The continuous angular adjustment range is segmented into discrete angular positions using multiple angular positioning portions (first, second, third positioning portions) on the adapter bracket that align with corresponding slots on the tilt bracket. This segmentation allows the system to provide both easy continuous adjustment and reliable discrete locking at specific angles.
Solution Approach 2:
A locking member is introduced as an intermediary component that physically connects the adapter bracket and tilt bracket at selected angular positions. The locking member engages with the angular positioning portions and corresponding slots to definitively lock the angular orientation, preventing accidental movement while maintaining ease of adjustment when unlocked.
2Device complexity
If friction knobs are used to maintain angular orientation, then device complexity is reduced, but reliability deteriorates as the mechanisms can be forced from set positions
Solution Approach 1:
The adapter bracket includes multiple angular positioning portions (first, second, third positioning portions) that divide the angular adjustment range into discrete positions. Each positioning portion corresponds to a specific angular orientation and engages with slots on the tilt bracket to provide secure locking without requiring complex friction mechanisms.
Solution Approach 2:
The locking member serves as a simple intermediary component that provides definitive locking by physically connecting the adapter bracket and tilt bracket at selected angular positions. This simple locking mechanism engages with the segmented positioning portions to prevent accidental movement while maintaining overall system simplicity.
3Reliability
If multiple angular positioning portions are implemented with a locking member, then reliability of position fixation is improved, but device complexity increases
Solution Approach 1:
Multiple angular positioning portions (first, second, third positioning portions) are merged into a single adapter bracket structure, allowing the bracket to provide multiple discrete angular positions through one integrated component. This merging approach provides reliable multi-position locking without requiring separate mechanisms for each angle, thereby limiting the increase in device complexity.

AI summary
A mounting system comprising an incremental angular position and locking system. A tilt bracket is configured to operatively connect to a surface, and an adapter bracket is operatively and movably connected to the tilt bracket, with the adapter bracket being configured to operatively connect to an object such as an audio/video device. A plurality of angular position features are associated with one of the tilt bracket and the adapter bracket, and an angular positioning element is configured to selectively engage at least one of the plurality of angular position features. When the angular positioning element is in engaged with at least one angular position feature, the adapter bracket is impeded from moving relative to the tilt bracket. When the angular positioning element is not in engagement with at least one angular position feature, the adapter bracket is substantially free to move relative to the tilt bracket.
