Solution Overview

Problem

Contemporary aircraft refueling systems require a robust and costly refueling control panel to withstand harsh environments, which adds weight and expense due to the need for physical and electronic protection, and is cumbersome to use in varying conditions.

Innovation Solution

A wireless communication system between the aircraft and refueling apparatus allows for remote control of fuel tank filling, eliminating the need for an aircraft-mounted refueling control panel by using a first controller on the aircraft and a second controller on the refueling apparatus to manage fuel flow and quantity based on stored fuel profiles and real-time sensor data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a robust refueling control panel is used to withstand harsh environments, then reliability is improved, but weight increases

Engineering Contradiction:
Improverefueling control panel reliabilityVSAvoidrefueling control panel weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The control panel is completely removed from the aircraft structure and relocated to the ground-based refueling apparatus. This extraction eliminates the need for a robust, heavy control panel on the aircraft while maintaining all necessary control functions at the refueling location.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A wireless communication system serves as an intermediary between the aircraft's fuel system and the ground control. This mediator enables control functions to be performed remotely without requiring physical connection or heavy protective structures on the aircraft.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a robust refueling control panel is used to withstand harsh environments, then reliability is improved, but cost increases

Engineering Contradiction:
Improverefueling control panel reliabilityVSAvoidrefueling control panel cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The control panel is extracted from the aircraft and placed in the refueling apparatus, eliminating the need for expensive, robust control panels on the aircraft. The aircraft's existing systems are leveraged instead, reducing overall cost.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The control functions are replicated in the ground-based refueling apparatus rather than requiring duplicate robust control panels on the aircraft. This copying approach allows the use of less expensive control systems since they don't need to withstand harsh environmental conditions.

Inventive Principle:
Principle #26Copying

3Ease of operation

If a refueling control panel is mounted on the aircraft for fuel monitoring, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improvefuel monitoring operationVSAvoidrefueling control panel complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control panel is extracted from the aircraft and relocated to the refueling apparatus. This simplifies the aircraft's systems by removing complex control panel hardware while maintaining ease of operation through wireless communication interfaces that are simpler and more versatile.

Inventive Principle:
Principle #2Taking out (Extraction)
