Solution Overview

Problem

The low matching degree between modified tooling and aircraft during the manufacturing process leads to increased manufacturing time and cost, quality issues, and potential accidents due to the independent development of aircraft and process equipment, and the use of incorrect or damaged tooling.

Innovation Solution

A method and device for aircraft tooling modification that generates a tooling change order and modified manufacturing bill of materials based on a design plan, evaluates tooling, and establishes an association relationship between manufacturing and tooling bills of materials to improve the matching degree, ensuring the modified tooling aligns with the aircraft design plan.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If aircraft and process equipment are developed independently, then development flexibility is improved, but the matching degree between tooling and aircraft deteriorates

Engineering Contradiction:

Improvedevelopment flexibilityVSAvoidmatching degree

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent establishes a feedback mechanism where tooling evaluation results are continuously fed back to update the association relationship between manufacturing bills of materials and tooling bills of materials. This ensures that independent developments of aircraft and tooling remain synchronized through iterative refinement of the matching data, resolving the contradiction between development flexibility and matching precision.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary association relationship database that links manufacturing bills of materials with tooling bills of materials. This intermediary structure enables independent development of aircraft and tooling while maintaining their matching degree through the mediating layer that coordinates changes between the two independently developed systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If tooling modification is performed without systematic evaluation, then modification speed is improved, but tooling-aircraft matching quality deteriorates

Engineering Contradiction:

Improvemodification speedVSAvoidtooling-aircraft matching quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary tooling evaluation and generates manufacturing change orders before actual tooling modification. This preliminary action ensures that the modified tooling will match the aircraft design requirements, preventing mismatches while maintaining efficient modification throughput through advance planning and validation.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If manual tooling modification planning is used, then system complexity is reduced, but manufacturing time and cost increase

Engineering Contradiction:

Improvesystem complexityVSAvoidmanufacturing time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent replaces manual tooling modification planning with an automated computer-based system that retrieves data, performs evaluations, and generates modification orders automatically. This substitution of mechanical/manual processes with automated computing systems reduces manufacturing time and cost while managing system complexity through software-based workflows.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If incorrect tooling is used due to poor matching, then tooling availability is improved, but aircraft quality deteriorates

Engineering Contradiction:

Improvetooling availabilityVSAvoidaircraft quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements feedback through tooling evaluation and association relationship updates that ensure only properly matched tooling is available for use. This feedback mechanism prevents incorrect tooling from being utilized by continuously validating the matching status and updating the system state, thereby maintaining aircraft quality while ensuring tooling availability.

Inventive Principle:

Principle #23Feedback
