Solution Overview

Problem

The use of touch tablets in aircraft cockpits is hindered by issues such as interference from magnetic fields, ergonomic discomfort, inadequate brightness and contrast, limited autonomy, and distraction from notifications, as well as the lack of a secure housing leading to potential damage.

Innovation Solution

An interface system that includes a display device with a dedicated support for portable computer equipment, providing power supply, bidirectional data transfer, and a communication gateway to overlay tablet data on the display, with ergonomic enhancements and protection against external factors, allowing control gestures to be translated and notifications to be managed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If touch tablets are used in aircraft cockpits, then ease of operation and ergonomics are improved, but reliability deteriorates due to magnetic field interference

Engineering Contradiction:
ImproveergonomicsVSAvoidmagnetic field interference
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a protective housing as an intermediary barrier between the touch tablet and the magnetic field sources in the cockpit environment. This housing shields the capacitive touch sensor from magnetic field interference while maintaining touch functionality, thus preserving ease of operation while improving reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If touch tablets are used without housing, then ease of operation is improved, but object-generated harmful factors worsen due to potential damage and falling

Engineering Contradiction:
Improveease of useVSAvoiddamage risk
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The protective housing serves as a preventive measure that cushions and protects the touch tablet from potential damage during handling, transport, and use in the cockpit. It prevents falling and impact damage before they can occur, eliminating the harmful factors while maintaining the ease of use benefits

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Duration of action of moving object

If tablet autonomy is increased, then duration of action is improved, but loss of energy worsens due to power consumption requirements

Engineering Contradiction:
ImproveautonomyVSAvoidpower consumption
Core Design Contradiction:
Duration of action of moving objectVSLoss of energy

Solution Approach 1:

The system dynamically manages power consumption by enabling the touch tablet to enter low-power states when not actively being used, while maintaining connectivity to the aircraft's electrical system for supplemental power. This dynamic power management extends autonomy during flight while minimizing energy loss

Inventive Principle:
Principle #15Dynamics

4Illumination intensity

If display brightness is increased for cockpit visibility, then illumination intensity is improved, but use of energy worsens

Engineering Contradiction:
ImprovebrightnessVSAvoidpower consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The display device incorporates adaptive brightness control that adjusts illumination intensity based on ambient light conditions and operational context. During daytime flights, brightness is optimized for visibility, while during nighttime operations, brightness is reduced to conserve energy, thus balancing illumination needs with power consumption

Inventive Principle:
Principle #35Parameter changes
