Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If manual measurement and trial-and-error methods are used for fuselage alignment, then measurement flexibility is maintained, but alignment time and labor requirements increase significantly

Engineering Contradiction:
Improvealignment timeVSAvoidmeasurement system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical measurement tools with an automated optical measurement system using transmitters and reflector targets. This substitution eliminates the need for hand tools and manual measurement processes, directly reducing alignment time while the automated calculation system handles the complexity of processing measurement data.

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

Solution Approach 2:

The measurement system is designed to be self-sufficient by automatically acquiring measurements from multiple transmitters and reflector targets, then autonomously calculating the required fuselage structure movements. This self-service capability eliminates the need for numerous human operators to manually record and process measurements, significantly reducing labor requirements.

Inventive Principle:
Principle #25Self-service

2Productivity

If numerous separate measurements are acquired using hand tools, then measurement coverage is comprehensive, but labor intensity and operational complexity increase

Engineering Contradiction:
Improvealignment efficiencyVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent merges multiple separate measurement operations into a single integrated automated system. Instead of using numerous hand tools for separate measurements, the system combines multiple transmitters and reflector targets into one coordinated measurement network that simultaneously captures all necessary alignment data, dramatically improving productivity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces transmitters and reflector targets as intermediary elements between the fuselage structures and the measurement system. These intermediaries enable automated measurement acquisition without requiring direct human intervention for each measurement point, simplifying operation while maintaining comprehensive measurement coverage.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If manual recording and uploading of measurements is performed, then data accuracy can be verified, but time consumption and labor requirements increase

Engineering Contradiction:
Improveposition measurement accuracyVSAvoiddata processing time
Core Design Contradiction:

Solution Approach 1:

The patent replaces manual recording and data upload processes with automated electronic data capture and transmission. The measurement system directly transmits position data from transmitters and reflector targets to the calculation system, eliminating manual recording steps while maintaining measurement precision through automated data acquisition.

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

4Extent of automation

If trial-and-error methods are used to calculate fuselage movement distances, then flexibility in adjustment is maintained, but the number of iterations and time required increase

Engineering Contradiction:

Solution Approach 1:

The patent replaces trial-and-error calculation methods with an automated computational system that directly calculates the required fuselage structure movements based on measured position data. This substitution eliminates iterative adjustments while the calculation system handles the complexity of determining precise movement distances and directions.

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

Solution Approach 2:

The patent implements a feedback mechanism where the measurement system continuously monitors fuselage structure positions and the calculation system determines required adjustments. This closed-loop feedback enables automated alignment without trial-and-error iterations, as the system directly computes the corrective movements needed based on real-time position measurements.

Inventive Principle:
Principle #23Feedback
