Solution Overview

Problem

The assembly of profile components on internal frame structural components of an aircraft is challenging due to the difficulty in accessing these areas, which are ergonomically unsuitable for personnel, and the use of heavy or unwieldy tools complicates the installation process.

Innovation Solution

A method and assembly system utilizing a robotic arm with a tool holder and gripping device that allows profile components to be mounted through existing openings in the aircraft's outer skin, enabling alignment, fixation, and attachment of components using fastening means, with the option of a stop for alignment assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If personnel manually assemble profile components in difficult-to-reach areas of the aircraft, then the assembly work can be performed, but the working conditions are ergonomically unsuitable and the process is difficult

Engineering Contradiction:
Improveease of assemblyVSAvoiddifficult-to-reach areas
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

A robotic arm with tool holder serves as an intermediary device to perform assembly operations in difficult-to-reach areas of the aircraft. The robotic system can be positioned outside the aircraft and guide tools through openings to access internal frame structures, eliminating the need for personnel to work in ergonomically unsuitable positions inside the aircraft

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual mechanical assembly operations with an automated robotic system. The robotic arm, controlled by a control unit, performs picking, guiding, aligning, and fastening operations that would otherwise require personnel to physically access confined spaces inside the aircraft, thereby improving ease of operation

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

2Strength

If heavy or unwieldy tools are used for connecting frame components, then the fastening function is achieved, but the installation process becomes even more difficult for personnel

Engineering Contradiction:
Improvefastening strengthVSAvoidinstallation difficulty
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The robotic arm with tool holder acts as an intermediary that delivers fastening tools to the work area without requiring personnel to manually handle heavy equipment. The system maintains strong fastening capability while transferring the burden of tool handling to the robotic system

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The robotic system performs the entire assembly process autonomously under control unit guidance, picking components, positioning them, and applying fasteners without human intervention in the difficult-to-reach area. The system serves itself by automatically completing all installation steps

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If multiple tools are used for alignment and fastening operations, then the assembly precision is improved, but the complexity of the assembly system increases

Engineering Contradiction:
Improvealignment precisionVSAvoidnumber of tools
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple assembly functions (picking, guiding, aligning, and fastening) into a single integrated robotic system with a multi-functional tool holder. The tool holder can accommodate different fastening means and positioning devices, eliminating the need for multiple separate tools and reducing system complexity while maintaining precision

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The tool holder is designed as a universal platform that can perform multiple functions: holding profile components, guiding them to the correct position, aligning them with frame structures, and applying various fastening means. This multi-functional design reduces the number of separate tools needed while maintaining assembly precision

Inventive Principle:
Principle #6Universality (Multi-functionality)
