Aircraft Display Screen with Reel Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cockpit information display devices are limited by fixed cable bundles that restrict screen positioning, interfering with the environment and not ergonomically adaptable to changing pilot needs during different flight phases.
Innovation Solution
An information display device with a screen and a rear surface that holds a cable bundle, allowing it to be wound or unwound, enabling the screen to be moved between fixed and secondary positions without interfering with flight instruments, and allowing reversible winding for flexible placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable bundle is continuously supplied to ensure display continuity, then information display reliability is improved, but the screen positioning flexibility deteriorates
Solution Approach 1:
The cable bundle is made dynamically adjustable through a reel mechanism that allows it to be wound and unwound. This enables the screen to be repositioned flexibly while maintaining continuous cable supply, resolving the contradiction between reliability and adaptability
Solution Approach 2:
A reel mechanism is introduced as an intermediary device between the screen and the fixed cable supply point. This intermediary allows the cable to be stored compactly when not in use and deployed when needed, enabling screen movement without compromising display continuity
2Reliability
If the cable bundle is fixed to ensure stable connection, then connection reliability is improved, but the screen mobility deteriorates
Solution Approach 1:
The cable connection system transitions from a fixed state to a dynamic one, where the cable can be wound onto a reel for mobility and unwound for stable connection. This dynamic adjustment allows the screen to be moved easily while maintaining reliable connection when positioned
3Ease of manufacture
If the screen occupies a fixed position to simplify installation, then installation complexity is reduced, but the ergonomic adaptability deteriorates
Solution Approach 1:
The screen mounting system incorporates a movable reel mechanism that allows the screen to be repositioned to different locations and orientations. This maintains simple installation procedures while enabling ergonomic adaptability to suit different pilot preferences and flight phases
4Object-affected harmful factors
If the cable bundle is wound against the rear surface to protect it, then cable protection is improved, but the screen positioning freedom deteriorates
Solution Approach 1:
The cable winding system on the reel is designed to be dynamically adjustable, allowing the cable to be wound compactly against the rear surface for protection during storage, and unwound when the screen needs to be repositioned. This maintains both cable protection and positioning freedom

AI summary
An aircraft cockpit that includes an information display device with a screen having a display surface and a rear surface opposite the display surface, and a cable harness connected to the screen. The rear surface includes a mechanism for retaining the cable harness substantially wound against the rear surface. The information display device is mobile within the cockpit.
