Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat-panel display devices are vulnerable to damage from ambient conditions such as rain, snow, and other environmental contaminants when placed in outdoor or challenging indoor settings, requiring effective protection to maintain performance and longevity.
Innovation Solution
A substantially sealed enclosure system comprising a bezel, a transparent front cover, and an enclosure housing, with a bezel seal to prevent liquid ingress, designed to house flat-panel displays and provide thermal modulation and enhanced visibility features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display devices are placed in outdoor or challenging indoor settings, then the application and placement versatility is improved, but the vulnerability to environmental contaminants increases
Solution Approach 1:
The enclosure is divided into multiple components including a bezel, front cover, enclosure housing, and sealing elements that can be independently manufactured and assembled. This segmentation allows each component to be optimized for its specific function while collectively providing environmental protection for the display device placed in challenging settings.
Solution Approach 2:
Sealing elements and gaskets are introduced as intermediary components between the bezel, front cover, and enclosure housing to create a protective barrier. These intermediaries prevent direct contact between environmental contaminants and the display device, enabling versatile placement in outdoor or challenging indoor environments.
2Reliability
If environmental enclosures are developed to protect display devices, then the protection from elements is improved, but the enclosure bulk increases
Solution Approach 1:
The enclosure employs thin-film sealing elements, gaskets, and flexible barriers that provide effective environmental protection without adding significant bulk. These thin-film components create a protective seal between the display device and external elements while maintaining a compact overall enclosure structure.
Solution Approach 2:
The enclosure components are designed to nest within each other, with the bezel, front cover, and enclosure housing fitting together in a compact configuration. This nesting approach maximizes the protective function while minimizing the overall enclosure volume and bulk.
3Reliability
If sealing arrangements are implemented to prevent liquid ingress, then the resistance to liquid ingress is improved, but the manufacturing complexity increases
Solution Approach 1:
The sealing system is segmented into discrete sealing elements and gaskets that can be independently manufactured and assembled between the bezel, front cover, and enclosure housing. This segmentation simplifies the manufacturing process by allowing each sealing component to be produced separately using standard techniques, then assembled into the complete enclosure.
Solution Approach 2:
Standardized sealing elements and gaskets serve as intermediary components that facilitate the assembly process. These pre-fabricated sealing components can be easily installed between enclosure parts, providing reliable liquid ingress protection while maintaining ease of manufacture through standardized interfaces and attachment methods.

AI summary
An enclosure for enclosing a flat panel display for viewing that is substantially sealed and resistant to liquid ingress. The enclosure comprises a bezel, a substantially transparent front cover, and an enclosure housing. The bezel has a peripheral surface defining an enclosure area, an inner edge defining a display opening, and a rear surface. The substantially transparent front cover is operatively connected to the bezel and covers the display opening. The enclosure housing has a front opening and a flange disposed about and extending from the front opening. The bezel and the enclosure housing are joined together at a joining region that is substantially sealed and resistant to liquid ingress. The bezel, the front cover, and the enclosure housing define the enclosure, which is configured to receive a flat panel display therein.
