Solution Overview

Problem

Current masking methods for aircraft windows are cumbersome and prone to positioning errors due to the complexity of handling and the need for precise alignment of multiple masks, leading to increased material consumption and aesthetic issues during painting operations.

Innovation Solution

A masking kit with a film having an adhesive underside and removable protective sheet, featuring visualization means such as through-holes and positioning aids like lines and windows, allowing for precise positioning and easy alignment on the aircraft window surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If traditional adhesive strips are used to attach masks around the window perimeter, then the mask can cover a slightly larger area than the window itself, but the handling becomes complex and precise positioning on the window becomes difficult

Engineering Contradiction:
Improvemask coverage areaVSAvoidhandling complexity
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent combines multiple masks into a single integrated masking kit that covers the window and peripheral areas simultaneously. This merging eliminates the need to handle multiple separate masks with adhesive strips, reducing handling complexity while maintaining comprehensive coverage area.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The masking kit is divided into distinct functional zones: a first masking area for the window glass, a second masking area for the peripheral seal, and a third masking area for the surrounding surface. This segmentation allows each zone to be optimized independently while simplifying overall application through a single integrated structure.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple masks are used to cover different areas around the window, then comprehensive protection is achieved, but the number of manipulations increases and positioning errors increase

Engineering Contradiction:
Improveprotection completenessVSAvoidnumber of manipulations
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent merges multiple individual masks into a single integrated masking kit that provides comprehensive protection for the window, peripheral seal, and surrounding areas. This single kit replaces multiple separate masking operations, reducing the number of manipulations from three or more separate mask applications to one unified application while maintaining complete protection coverage.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the mask is made flexible to adapt to the surface, then it can conform to the window shape, but precise positioning becomes more difficult

Engineering Contradiction:
Improvesurface conformityVSAvoidpositioning accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The masking kit incorporates pre-positioned alignment markers and reference features that are prepared in advance during manufacturing. These preliminary positioning aids guide the operator during application, ensuring accurate alignment with the window and peripheral areas before the flexible material is fully adhered, thus maintaining positioning accuracy despite flexibility.

Inventive Principle:
Principle #10Preliminary action

4Stability of the object's composition

If adhesive strips of sufficient size are used to secure the mask, then the mask remains stable during painting, but the mask's flexibility and handling become more complex

Engineering Contradiction:
Improvemask stabilityVSAvoidmask structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent integrates the adhesive attachment mechanism directly into the masking kit structure rather than using separate adhesive strips. The adhesive layer is incorporated as an integral part of the masking material, eliminating the need for additional attachment components and reducing overall structural complexity while maintaining stable adhesion during the painting process.

Inventive Principle:
Principle #5Merging (Combining)
