Solution Overview

Problem

Aircraft touch screen displays experience vibration-induced errors during turbulence or mechanical vibrations, leading to frustration and decreased efficiency for flight crew members as they inadvertently select incorrect elements, requiring re-entry of intended inputs.

Innovation Solution

A computer-implemented method and system that utilize processors to receive data from vibration sensors and tracking devices to determine a corrected user interaction by comparing actual and intended interactions, adjusting for sensed vibrations and sending command signals to aircraft components to perform the intended function.

1Productivity

If touch screen display is used in aircraft, then efficiency and data consolidation are improved, but vibration-induced input errors increase

Engineering Contradiction:

ImproveefficiencyVSAvoidinput accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system uses vibration sensors to detect aircraft vibrations and tracking devices to monitor user interaction intent. This feedback loop allows the system to identify when a vibration caused an unintended touch and automatically correct it by sending the intended command, thereby maintaining input accuracy while preserving touch screen efficiency

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary system between the touch screen and the aircraft control components. This intermediary layer includes vibration sensors, tracking devices, and a processor that mediates the interaction by detecting vibrations, determining intended vs. actual inputs, and correcting commands before they reach the aircraft systems

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If vibration correction system is implemented, then input accuracy is improved, but device complexity increases

Engineering Contradiction:

Improveinput accuracyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses a touch screen display that serves multiple functions: it displays aircraft information, accepts user input, and acts as part of the correction system by showing visual feedback about vibration detection and input correction status. This multi-functionality reduces the need for separate dedicated components for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)
