Modular Seatback Display Shroud for Changing Screen Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger seat back shrouds require redesign or replacement when IFE devices change in size or shape, leading to significant costs due to their one-piece configuration.
Innovation Solution
A modular display assembly comprising a video shroud with an inner opening and an adaptable lip, allowing for easy replacement of the adaptor to accommodate different display sizes and shapes without modifying the shroud, which can be standardized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-piece protective shroud is used to cover the display device, then the device is protected from damage or tampering, but the shroud must be completely redesigned or replaced when the device shape or size changes
Solution Approach 1:
The shroud is divided into a standardized main body portion and a replaceable adaptor component. The adaptor can be removed and replaced to accommodate different display sizes and shapes, while the main shroud structure remains unchanged. This segmentation allows the protective function to be maintained while providing adaptability to various display configurations.
2Strength
If the shroud is configured to snugly conform to the seat back and device perimeter, then a durable protective surface is provided, but considerable cost is involved in replacing or redesigning the shroud for each device change
Solution Approach 1:
The shroud system is segmented into an expensive, durable main body that remains in place and a smaller, less expensive adaptor that can be replaced. This allows the costly protective surface to be reused while only the smaller adaptor needs to be manufactured and replaced when device specifications change, significantly reducing replacement costs.
Solution Approach 2:
The main shroud body is designed as a universal component that can accommodate multiple different display devices through the use of various adaptors. This multi-functionality allows a single shroud design to serve multiple purposes with different display configurations, reducing the need for custom shroud manufacturing.
3Ease of manufacture
If a modular shroud with replaceable components is used, then cost-effective updates are enabled, but the shroud structure becomes more complex
Solution Approach 1:
The shroud is segmented into two main components: a standardized body and a replaceable adaptor. This segmentation enables cost-effective updates by allowing only the adaptor to be replaced rather than the entire shroud, while the added complexity is minimized by keeping the adaptor design simple and the interface between components straightforward.

AI summary
Described are display assemblies having a display coupled to a passenger seat back, a video shroud coupled to the passenger seat back and with an inner opening positioned adjacent the display, wherein a gap is positioned between an outer edge of the display and an edge of the inner opening, and an adaptor having a lip and coupled to the video shroud, wherein the lip is positioned adjacent the gap. A portion of the lip may surround at least the outer edge of the display and/or may overlap a portion of the video shroud.
