Solution Overview

Problem

The traditional method of replacing degraded decorative laminates on aircraft involves the entire removal and replacement, which is costly and inefficient, as it requires the entire laminate to be removed and replaced even for minor damage, increasing material, labor, and time costs.

Innovation Solution

A method and system for applying and replacing tactile textured substrates on aircraft surfaces by forming and curing tactile features on substrates using UV light, allowing selective removal and replacement of substrate portions, and using adhesive or mechanical fasteners for coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire laminate is removed and replaced when degraded in small areas, then the aesthetic integrity and appearance of the aircraft surface is maintained, but the cost (materials, labor, time) and complexity of the replacement process increases significantly

Engineering Contradiction:

Improveaesthetic integrityVSAvoidreplacement process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The laminate is divided into multiple interchangeable panels that can be independently removed and replaced. Each panel is a discrete unit with standardized coupling mechanisms, allowing only the degraded panel to be replaced rather than the entire laminate. This segmentation enables localized maintenance while preserving the overall aesthetic integrity of the aircraft surface.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention applies different properties to different parts of the laminate system. Each panel can be independently manufactured with specific tactile textures, decorative patterns, or material compositions suited to its location. This allows localized replacement of only the degraded panel while maintaining the unique aesthetic qualities of each region of the aircraft surface.

Inventive Principle:

Principle #3Local quality

2Reliability

If the entire laminate is removed and replaced when degraded, then complete surface coverage and uniform appearance are ensured, but the time and labor required for maintenance increases

Engineering Contradiction:

Improvesurface coverageVSAvoidmaintenance time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The laminate system is segmented into multiple independently replaceable panels with standardized dimensions and coupling mechanisms. This allows maintenance personnel to quickly remove and replace only the specific degraded panel without disturbing adjacent panels, dramatically reducing maintenance time compared to replacing the entire laminate while ensuring complete surface coverage is maintained.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple replacement panels are pre-manufactured and stored in readiness, matching the aircraft's existing panels in appearance and dimensions. When a panel degrades, a pre-prepared replacement panel can be immediately installed, minimizing aircraft downtime and ensuring continuous complete surface coverage without the time-consuming process of manufacturing or custom-fitting replacement sections.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If tactile features are printed onto the substrate using UV light, then the tactile texture and aesthetic appearance are enhanced, but the manufacturing process complexity and equipment requirements increase

Engineering Contradiction:

Improvetactile feature precisionVSAvoidprinting process complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention replaces traditional mechanical embossing or molding processes with UV light-based direct digital printing to create tactile features on the substrate. This photopolymerization process allows precise deposition of textured material directly onto the panel surface through digital patterning, achieving high manufacturing precision for tactile features while using a more flexible and potentially simpler printing system rather than complex mechanical forming equipment.
