Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft cabin management systems allow limited interaction between passengers and cabin equipment, requiring passengers to reconfigure applications when their needs change, and do not facilitate efficient communication and service delivery between passengers and crew.
Innovation Solution
An aircraft cabin system where passenger terminals, such as smartphones or tablets, are integrated into the cabin environment, allowing wireless communication with seat management units to enable personalized seat adjustments and direct communication with crew terminals, using application software to interpret data and display options, and a data exchange system that minimizes radio link power and ensures data transmission reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passengers use traditional remote controls or dedicated terminal devices to operate cabin equipment, then device functionality is reliable, but device complexity and passenger portability are reduced
Solution Approach 1:
The patent enables universal portable terminals (smartphones, tablets) to perform multiple functions including seat control, entertainment, communication with crew, and personal data storage. The terminal acts as a multi-functional device replacing multiple dedicated cabin controls, allowing passengers to operate various cabin equipment using their existing personal devices without requiring specialized remote controls or dedicated terminals.
Solution Approach 2:
The patent introduces a portable terminal as an intermediary device between the passenger and the cabin equipment. The terminal communicates with the seat management unit and crew terminals through wireless connections, mediating all interactions. This intermediary approach allows passengers to control cabin equipment without direct connection to each device, simplifying the interface while maintaining system functionality.
2Adaptability or versatility
If passengers reconfigure applications when their needs change, then adaptability is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-storing passenger preferences, seat adjustments, and service requests in the portable terminal before flights. The terminal maintains a library of pre-configured applications and settings that can be instantly recalled and activated based on current needs, eliminating the time-consuming process of reconfiguration. Passenger profiles and preferences are saved in advance for immediate retrieval.
Solution Approach 2:
The patent enables dynamic adaptability where the portable terminal automatically adjusts and reconfigures applications based on real-time passenger needs and flight context. The system dynamically switches between different functional modes (seat control, entertainment, communication) without requiring manual reconfiguration, adapting seamlessly as passenger requirements change during the flight.
3Measurement precision
If dedicated remote controls are used for each cabin equipment, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent employs a universal portable terminal that can precisely control multiple different cabin equipment types (seat adjustments, entertainment system, lighting, temperature control) through a single device. The terminal maintains precise control capabilities for each equipment type while eliminating the need for multiple dedicated remote controls, thereby reducing overall device complexity without sacrificing control precision.
Solution Approach 2:
The patent utilizes parameter changes by transmitting specific control signals and data parameters from the portable terminal to the target equipment. The system changes operational parameters (seat position, temperature, volume) through wireless communication protocols, maintaining precise control through digital parameter transmission rather than physical button presses on dedicated remotes.
4Ease of operation
If wireless communication with multiple terminals is implemented, then ease of operation is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic action by establishing scheduled communication intervals between the portable terminal and cabin equipment. Instead of maintaining continuous wireless connections, the system uses periodic data exchanges and connection activations only when communication is needed, reducing overall energy consumption while maintaining ease of operation. The terminal wakes up or activates communication protocols only during required interactions.
Solution Approach 2:
The patent extracts and optimizes the wireless communication function by using efficient data transmission protocols and minimizing the duration and frequency of radio link activations. The system extracts only the essential communication requirements for each interaction, transmitting minimal necessary data between the portable terminal and cabin systems, thereby reducing energy usage while preserving full operational capability.

AI summary
An aircraft cabin (100) comprises a plurality of seats (20), at least one of which is paired with a passenger terminal (40). These terminals communicate wirelessly to transmit seat adjustment capacity data from a seat management unit (22) to the passenger terminal and to transmit seat adjustment instructions from the passenger terminal (40) to the seat management unit. The passenger terminal (40) includes application software that interprets the data received from the seat management unit to display a representation of the possible adjustments on a screen (41) of the passenger terminal and interprets operator actions on passenger terminal keys as seat adjustment instructions.A main computer (10) in the cabin provides communication between the passenger terminals (40) and the crew terminals (31, 32) to transmit, by displaying on terminal screens, requests from a passenger to the crew and from the crew to a passenger or a group of passengers.
