Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple capacitive probes and electronic components are installed within the fuel tank to accurately determine fuel volume and mass, then measurement precision is improved, but device complexity and installation/maintenance costs increase

Engineering Contradiction:
Improvefuel volume and mass determination accuracyVSAvoidnumber of probes and electronic components
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces capacitive probes and electronic measurement components with an optical imaging system. An imager captures images of the fuel tank interior, and image processing algorithms determine fuel volume and mass from these visual data, eliminating the need for multiple electronic probes within the tank.

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

Solution Approach 2:

The patent creates an optical copy (image) of the fuel tank interior to measure fuel properties. Instead of directly measuring with probes, the system captures visual information and processes it to derive fuel volume and mass, using the image as a substitute for physical measurement devices.

Inventive Principle:
Principle #26Copying

2Measurement precision

If multiple probes are installed within the fuel tank to accurately determine fuel properties, then measurement precision is improved, but installation and maintenance costs increase

Engineering Contradiction:

AI summary

A method can include generating image data of an interior of a fuel tank (12) disposed within a wing of an aircraft, and determining (114), by a processing device, an amount of wing bending of the wing of the aircraft based on the generated image data of the interior of the fuel tank. The method can further include producing (116), by the processing device, a fuel measurement value representing an amount of fuel contained in the fuel tank based on the amount of wing bending of the wing of the aircraft, and outputting (118), by the processing device, an indication of the fuel measurement value.
