Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sheet material is used, then it meets FAA standards, but it lacks durability and ease of installation
Solution Approach 1:
The sheet material is divided into multiple functional layers: a protective polycarbonate layer for durability and an adhesive layer for ease of installation. This segmentation allows each layer to specialize in one function, resolving the contradiction between durability and ease of installation.
Solution Approach 2:
The invention uses a composite structure combining polycarbonate material with adhesive properties. This composite material integrates the hardness and protection of polycarbonate with the bonding capabilities of adhesive, simultaneously achieving both durability and ease of installation.
2Adaptability or versatility
If single color sheet material is used, then it is simple to manufacture, but it is limited to single application
Solution Approach 1:
The sheet material is designed with universal applicability through its multilayer structure that can be applied to various aircraft surfaces including bulkheads, bins, and carts. The adhesive layer enables versatile application while the manufacturing process remains relatively simple, resolving the contradiction between versatility and manufacturing simplicity.
3Ease of operation
If multilayer structure with adhesive is used, then ease of installation is improved, but manufacturing complexity increases
Solution Approach 1:
The manufacturing process merges multiple operations into integrated steps. The polycarbonate and adhesive layers are combined in a way that allows for streamlined production, reducing the overall manufacturing complexity despite the multilayer structure. This merging approach enables ease of installation while controlling manufacturing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sheet material provides enhanced protection and ease of installation, meeting FAA requirements for durability and flexibility in application across different aircraft surfaces.
Implementation Method 1
The first time at 115° F. to get the material warm and soft
Implementation Method 2
A second compression pass is performed at 200-220 psi to bond the high durability adhesive to the material
Implementation Method 3
The hot film, with or without color is then cooled gradually and laid flat so that it does not curl
