Rear Cover Bracket Linkage for Adjustable Display Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with large or curved screens face challenges in providing a wide angle of view and easy repairability, particularly in their connection to external stands, which limits their adjustability and maintenance.
Innovation Solution
A display apparatus design featuring a connection unit with a bracket link that connects to a stand, allowing for tilting and sliding movements via a through hole in the rear cover, incorporating a bracket holder, plate, and elastic member for adjustable rotation and limited movement, enhancing adjustability and repairability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed connection structure is used between the display apparatus and stand, then structural stability is improved, but adjustability and angle of view are limited
Solution Approach 1:
The connection unit incorporates a bracket link that can rotate relative to the chassis along a predetermined axis, transforming the fixed connection into a dynamic adjustable connection. This allows the display apparatus to achieve multiple viewing angles and positions while maintaining structural stability through controlled rotational movement rather than rigid fixation.
Solution Approach 2:
The connection unit is divided into separate components including the bracket link, chassis mounting portion, and stand interface. This segmentation allows independent optimization of each component - the bracket link provides adjustability through rotation, while the mounting portions maintain structural stability, resolving the contradiction between flexibility and rigidity.
2Ease of repair
If the connection unit is integrated into the chassis, then structural stability is improved, but repairability becomes difficult
Solution Approach 1:
The connection unit is designed as a separable module that can be detached from the chassis through the rear cover opening. This modular segmentation enables easy removal and replacement of the connection unit for repair or maintenance without damaging the chassis structure, while the precise mounting interfaces ensure structural stability when assembled.
Solution Approach 2:
The connection unit is extracted as a distinct removable component from the chassis assembly, allowing it to be independently serviced. The rear cover opening provides access for removing and replacing the connection unit, enabling easy repair while the designed interfaces maintain structural integrity during normal operation.
3Adaptability or versatility
If a simple connection structure is used, then ease of manufacture is improved, but adjustability and functionality are limited
Solution Approach 1:
The bracket link incorporates a simple rotational joint mechanism that provides adjustable positioning without complex actuators or motors. This dynamic but mechanically simple design allows the apparatus to achieve multiple angles and positions while remaining easy to manufacture using conventional machining and assembly processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a wider angle of view and facilitates easy repair by allowing adjustable positioning and maintenance through the connection unit's sliding and tilting mechanisms, improving user interaction and maintenance accessibility.
Implementation Method 1
The fastener member of the bracket plate may include an elastic member. And a rotation angle of the bracket holder coupled with the bracket link may be limited by the elastic member.
