Solution Overview

Problem

Existing ground support equipment modules on aircraft are often overlooked during pre-flight checks, leading to potential incidents due to their presence on sensitive components, which are not visible to pilots and can cause overheating or engine failure.

Innovation Solution

A ground support equipment system with modules connected via physical wires or wireless RFID modules to a common interconnection device, such as a cockpit door handle, ensuring visible alerting to pilots, and an aircraft control system to prevent engine start if modules are not removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If ground support equipment modules are mounted to sensitive technical components for protection, then protection against environmental conditions is improved, but visibility during pre-flight check deteriorates

Engineering Contradiction:
Improveprotection against environmental conditionsVSAvoidvisibility during pre-flight check
Core Design Contradiction:
Object-affected harmful factorsVSDifficulty of detecting and measuring

Solution Approach 1:

The ground support equipment modules are equipped with colored flags or visually distinct markings that change or enhance their visibility. The flags are designed to be highly visible against the aircraft background, ensuring pilots can easily detect their presence during pre-flight checks regardless of environmental conditions.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

An intermediary alerting system is introduced between the ground support equipment modules and the pilot. This system includes visual indicators, flags, or electronic alerts that mediate the communication of the modules' presence to the pilot, ensuring they are noticed during pre-flight checks.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Difficulty of detecting and measuring

If colored flags are used as visible alerting means, then detectability is improved, but reliability deteriorates in rainy conditions

Engineering Contradiction:
Improvedetectability of ground support equipment modulesVSAvoidvisibility in rainy conditions
Core Design Contradiction:
Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The patent replaces or supplements mechanical visual alerting (colored flags) with electronic or sensor-based alerting systems. Sensors detect the presence of ground support equipment modules and trigger electronic alerts or lights that are not affected by rain, ensuring reliable detection in adverse weather conditions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

An electronic feedback system is implemented where sensors continuously monitor the presence of ground support equipment modules and provide real-time feedback to the pilot through electronic alerts, lights, or audio signals. This feedback mechanism ensures reliable detection regardless of environmental conditions.

Inventive Principle:
Principle #23Feedback

3Productivity

If ground support equipment modules are left mounted to avoid overlooking, then operational continuity is improved, but safety deteriorates due to potential overheating or engine failure

Engineering Contradiction:
Improveoperational continuityVSAvoidsafety during flight operation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary detection during pre-flight checks to identify ground support equipment modules that need to be removed. The alerting system ensures pilots are notified before flight operation begins, allowing time for safe removal and preventing potential overheating or engine failure during flight.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Electronic sensors and alerting systems provide continuous feedback about the presence of ground support equipment modules. This feedback mechanism ensures pilots are informed of any modules that remain mounted, enabling them to take corrective action before flight operation to maintain safety.

Inventive Principle:
Principle #23Feedback
