Hinged Electronic Display Housing for In-Place Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic displays, especially large and high-definition ones, face challenges in maintenance and repair due to their mounting positions, which often require removal from their locations for servicing, leading to costly and time-consuming processes, especially in trafficked or hard-to-access areas, resulting in valuable advertising revenue loss and downtime.
Innovation Solution
The design allows access to the rear of the display through the bottom of the housing, with a rotating front housing that can be opened for component replacement, and a removable front glass assembly that can be quickly changed by minimally-trained personnel, minimizing the need for display removal and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is mounted in difficult-to-access areas for optimal visibility and advertising value, then the display's visibility and advertising effectiveness are improved, but the ease of repair and maintenance deteriorates
Solution Approach 1:
The housing is divided into a first housing portion and a second housing portion that can be separated from each other. The first housing portion contains the display panel and is mounted in difficult-to-access areas, while the second housing portion can be removed to provide access to the rear of the display for maintenance and repair without removing the entire display from its mounted position.
2Ease of repair
If the display is removed from its mounted position for servicing, then the ease of repair is improved, but the loss of time and advertising revenue increases
Solution Approach 1:
The housing is segmented into removable and fixed portions, allowing maintenance personnel to access the rear of the display by removing only the second housing portion while the first housing portion remains mounted. This enables servicing to be performed in-place, significantly reducing downtime and preserving advertising revenue.
Solution Approach 2:
The second housing portion acts as an intermediary element that provides access to the rear of the display. By removing this intermediate component rather than the entire display assembly, maintenance can be performed quickly without full removal from the mounted position.
3Reliability
If the front glass assembly is secured with multiple fastening means for stability, then the reliability is improved, but the ease of repair deteriorates
Solution Approach 1:
The front glass assembly is secured with a limited number of fastening means (exactly four at the corners) rather than numerous fasteners along the entire perimeter. This provides sufficient stability for normal operation while allowing quick removal and replacement by minimally-trained personnel when needed.

AI summary
An electronic display which can be serviced without having to remove the display from its mounted position. A front housing and a rear housing are hingedly attached so that the front housing can rotate and allow access to the interior of the display. An axial force mechanism can be used to aid in rotating the front housing to an open position. A locking collar, support member, or axial locking member may be used to ensure that the front housing remains open. A removable front glass assembly or removable glass panel may be used with an exemplary embodiment. The front glass assembly or glass panel can be easily replaced if it becomes damaged by minimally-trained personnel. Gutters may be used between the front and rear housing as well as the front housing and front glass assembly to ensure an adequate seal against contaminates.
