Field Serviceable Display Assembly With Hinged Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic display assemblies are not field serviceable, making maintenance and repairs difficult, especially when they are connected to external power sources and communication networks, which increases costs and regulatory compliance challenges.
Innovation Solution
A field serviceable and replaceable assembly for electronic displays with hingedly mounted side assemblies that allow access to electronic components, featuring a sealed, powered, and cooled cavity, with separate connections for power and communications to avoid disturbing utility lines, and optional increased cooling through additional air channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic displays are encased in a housing to protect them from environmental conditions, then reliability is improved, but ease of repair deteriorates because servicing becomes difficult or impossible
Solution Approach 1:
The assembly is divided into separate serviceable portions (side assemblies) that can be independently accessed through hinged doors, while the main housing remains sealed for environmental protection. This segmentation allows technicians to access specific electronic components without compromising the overall sealed structure.
Solution Approach 2:
Hinged access doors serve as intermediary elements between the sealed housing and the need for component access. These doors provide a controlled interface that maintains the sealed environment while allowing periodic access for servicing electronic components.
2Adaptability or versatility
If electronic displays are connected to external power sources and communication networks, then functionality is improved, but device complexity increases due to additional connections and regulatory requirements
Solution Approach 1:
Power and communication connections are extracted from the main sealed housing and relocated to the serviceable side assemblies. This allows connections to be made and maintained outside the protected environment, reducing the complexity of maintaining sealed connections to utility lines.
Solution Approach 2:
The connection architecture transitions from a centralized approach to a distributed approach, where power and communication interfaces are positioned in multiple accessible locations (side assemblies) rather than requiring access to the main sealed housing.
3Reliability
If side assemblies are made fixed and sealed, then protection from environmental conditions is improved, but ease of operation deteriorates because access for maintenance is lost
Solution Approach 1:
The side assemblies transition from a static fixed structure to a dynamic structure with hinged doors that can open and close. This allows the assembly to adapt between maintaining a sealed environment during operation and providing access during maintenance, resolving the contradiction between protection and serviceability.
