Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming decorative panels in aircraft interiors are complex, time-consuming, and labor-intensive, requiring multiple steps including crushed core processing, trimming, adhesive application, and vacuum forming.
Innovation Solution
A method involving pressing a decorative layer with integrated decorative elements onto a substrate, where the decorative layer is made of thermoplastic material without fibers, and the substrate consists of a thermoplastic base material with carbon fibers, eliminating the need for adhesives and vacuum forming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional multi-step process (crushed core, trimming, adhesive application, vacuum forming) is used, then decorative panels can be formed, but the process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple traditional manufacturing steps (crushed core processing, trimming, adhesive application, and vacuum forming) into a single integrated pressing operation. The decorative layer is pressed directly onto the substrate in one step, eliminating the need for separate adhesive application and vacuum forming steps, thereby simplifying the overall manufacturing process.
Solution Approach 2:
The pressing operation serves multiple functions simultaneously: it forms the crushed core structure, trims the panel edges, bonds the decorative layer to the substrate, and forms the final panel shape. This multi-functional approach eliminates the need for separate specialized equipment and operations for each task.
2Productivity
If traditional multi-step process is used, then decorative panels can be formed, but the process becomes labor-intensive
Solution Approach 1:
The patent combines multiple traditional manufacturing steps (crushed core processing, trimming, adhesive application, and vacuum forming) into a single integrated pressing operation. The decorative layer is pressed directly onto the substrate in one step, eliminating the need for separate adhesive application and vacuum forming steps, thereby simplifying the overall manufacturing process.
Solution Approach 2:
The decorative elements are pre-integrated into the decorative layer before it is pressed onto the substrate. This preliminary integration eliminates the need for separate decorative element application steps during the manufacturing process, reducing both time and labor requirements.
3Strength
If adhesive including MEK is used, then decorative laminate can be bonded to panel, but material costs and potential harmful effects increase
Solution Approach 1:
The substrate and decorative layer bond to each other through direct pressing and molecular adhesion without requiring external adhesive materials. The thermoplastic materials in both layers soften under heat and pressure, enabling direct bonding that eliminates the need for separate adhesive substances and their associated harmful effects.
Solution Approach 2:
The patent removes the adhesive component entirely from the manufacturing process. By using direct thermoplastic bonding through pressing, the system extracts and eliminates the need for adhesive materials including MEK, thereby removing the source of harmful effects associated with adhesive application.
