Adjustment Hook Assembly for TV Pitch and Tilt Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audiovisual stands lack adjustable tilt and pitch mechanisms for audiovisual devices, resulting in a complex and bulky structure that is difficult to use effectively.
Innovation Solution
The adjustment hook assembly includes a support arm, a hook, a connector, and a support member, allowing for adjustable pitch and tilt angles by pivoting the support arm relative to the connector, which is fixedly connected to the audiovisual stand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hanger is connected with rotating apparatus to adjust the pitch angle of the TV, then the pitch angle is adjustable, but the structure becomes complex and occupies a large volume
Solution Approach 1:
The patent combines the pitch adjustment function and tilt adjustment function into a single integrated support arm structure. The support arm itself performs both pitch adjustment (by rotating relative to the connector) and tilt adjustment (by moving the hook along the support arm), eliminating the need for separate rotating apparatus and simplifying the overall structure.
Solution Approach 2:
The support arm serves multiple functions: it provides structural support, enables pitch adjustment through rotation at the connector, and enables tilt adjustment through hook repositioning. This multi-functionality reduces the number of separate components needed and simplifies the overall device structure while maintaining adjustability.
2Adaptability or versatility
If a hanger is connected with rotating apparatus to adjust the pitch angle of the TV, then the pitch angle is adjustable, but the device occupies a large volume
Solution Approach 1:
The patent merges pitch adjustment and tilt adjustment mechanisms into one compact support arm assembly. The rotation of the support arm relative to the connector provides pitch adjustment, while repositioning the hook along the support arm provides tilt adjustment, all within a compact volume without requiring additional rotating apparatus.
Solution Approach 2:
The patent uses dynamic, adjustable elements rather than fixed complex mechanisms. The support arm can rotate dynamically to adjust pitch, and the hook can be repositioned dynamically to adjust tilt, allowing for compact design while maintaining full adjustability functionality.
3Reliability
If two groups of hooks are mounted at intervals in a length direction of the support arm, then the TV can be fixed, but the tilting angle is not adjustable
Solution Approach 1:
The patent makes the hook position dynamic rather than fixed. The hook can be moved along the support arm to different positions, enabling tilt angle adjustment. The fastening mechanism allows the hook to be securely fixed at any position along the support arm, providing both adjustability and stability.
Solution Approach 2:
The support arm is divided into multiple segments or sections with hooks positioned at different locations. This segmentation allows selective engagement of different hook positions to achieve different tilt angles, while maintaining secure fixing at each position through the fastening mechanism.

AI summary
The invention discloses an adjustment hook assembly and a method of fixing an audiovisual device to an audiovisual stand, where a hook and a connector are respectively connected with a hanging arm of the audiovisual stand, a support arm is fixedly connected with the audiovisual device, the connector is pivotally connected with the support arm by a first fastener, the support arm is rotated to a predetermined position by relative rotation between the support arm and the connector to adjust a pitch of the audiovisual device to a desired angle, and a support member abuts against the support arm to avoid pivoting reset, which has the advantages of convenient adjustment and simplified structure.
