Aircraft Display Shielding Structure for Impact Debris Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panel units in aircraft are prone to glass debris scattering due to detachment of touch panels from the frame under impact, which is exacerbated by the demand for slim bezels and unpredictable turbulence, posing a safety risk.
Innovation Solution
A display device with a shielding component extending backward from the peripheral portion of the first panel, which prevents glass debris from escaping through the gap between the panel and the housing, even under impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesion area between the edges of the touch panel and the frame is increased to prevent detachment under impact, then the reliability of the assembly is improved, but the bezel width increases, making it difficult to meet slimming down requirements
Solution Approach 1:
The shielding component extends in the depth direction (front-to-back dimension) rather than increasing the lateral adhesion area. This dimensional transition allows the system to achieve impact protection without compromising the slim bezel design, as the shielding component utilizes the available depth space to provide both adhesion and shielding functions
2Length of moving object
If the bezel width is reduced to meet slimming down requirements, then the appearance and space utilization are improved, but the adhesion area between the touch panel and frame is decreased, making the assembly more susceptible to impact damage
Solution Approach 1:
The shielding component serves multiple functions simultaneously: it acts as both a structural element to maintain the slim bezel design and a protective component that provides impact shielding. By combining these functions into a single element, the system achieves both slimming down requirements and reliability improvement without requiring separate components for each function
3Reliability
If glass components are made more resistant to impact damage, then the safety is improved, but the weight and complexity of the display device increase
Solution Approach 1:
The shielding component is positioned to extend forward from the peripheral portion of the first panel, creating a protective barrier before impact reaches the glass components. This beforehand cushioning approach prevents direct impact to the glass, reducing the need for thicker or more complex glass structures, thereby maintaining safety while avoiding unnecessary weight and complexity

AI summary
A display device for use in an aircraft includes a first panel that is light-transmissive, a second panel that opposes a first back surface that is a back surface of the first panel, a housing, and a shielding component. The second panel displays an image on a second front surface, and includes a glass substrate. The housing defines a housing space that houses the second panel, and includes a side wall that supports a peripheral portion of the first panel. A shielding component includes one end connected to the peripheral portion of the first panel. The shielding component includes a portion that extends backward from the peripheral portion in an interior of the housing space.
