Aircraft Cabin Side Ledge Knob Integrating Multi-Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft cabin control systems operate independently for environmental and passenger comfort functions, lacking a consolidated interface for passengers and crew to efficiently manage multiple parameters like lighting, temperature, media, and window shades.
Innovation Solution
A graphical user interface (GUI) is integrated into a side ledge of an aircraft cabin, allowing users to control environmental and comfort parameters through a touch-sensitive knob or surface, enabling adjustments to light intensity, color, temperature, media type, content, and window shades, with prioritization of inputs to avoid conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent control systems are used for environmental and passenger comfort functions, then each function can be controlled independently, but the system complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines multiple independent control systems into a single consolidated I/O node located at the side ledge. This single interface integrates control for lighting, temperature, window shades, and entertainment systems, allowing passengers to manage all cabin functions from one location rather than using separate control panels throughout the cabin.
Solution Approach 2:
The side ledge I/O node is designed as a universal control interface that handles multiple functions simultaneously. It serves as both an environmental control station and an entertainment system interface, providing multi-functional capability in a single device that adapts to various user needs.
2Ease of operation
If control interfaces are distributed throughout the cabin, then accessibility is improved, but the number of control devices increases and ease of operation deteriorates
Solution Approach 1:
The patent consolidates numerous distributed control devices into a single side ledge I/O node. Instead of having separate switches, dials, and buttons scattered throughout the cabin for lighting, temperature, and entertainment controls, all these functions are merged into one accessible interface near the passenger seat.
3Adaptability or versatility
If multiple control inputs are allowed from different locations, then user flexibility is improved, but input conflicts increase and system reliability deteriorates
Solution Approach 1:
The system implements a prioritization scheme that preemptively prevents input conflicts by establishing a hierarchy of control authority. The side ledge I/O node is assigned higher priority than other control inputs in the cabin, so when multiple inputs are received simultaneously, the system knows in advance which input should take precedence, eliminating conflicts before they occur.

AI summary
A method of operation for a system incorporating a graphical user interface embedded in a knob disposed on a side ledge within a cabin of an aircraft includes displaying a menu for at least one controllable parameter, receiving a selection of the controllable parameter, displaying at least one control for the selected controllable parameter, receiving a control input for the selected controllable parameter, and adjusting the selected controllable parameter consistent with the control input. The controllable parameter comprises a plurality of controllable parameters selected from a group comprising light intensity, light color, temperature, media type, media content, media volume, and the degree of openness of at least one window shade. A knob and an executable computer program product also are provided.
