Solution Overview
Problem
Existing match dies for forming aircraft interior panels are large, bulky, heavy, and expensive, requiring complex tool storage and transportation due to their metal components, which increase weight and cost.
Innovation Solution
A system using metal mounting plates and forming plates with integrated heating elements, secured by temperature-resistant plastic bases formed via additive manufacturing, such as polycarbonate, to form panels through compression and heating, reducing weight and cost by using 3D printing for the plastic bases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal bases and mounting plates are used in match dies, then strength and heat resistance are improved, but weight and cost increase
Solution Approach 1:
The patent applies composite materials by combining metal forming plates with plastic bases and mounting plates. The metal forming plates provide necessary strength for panel formation, while the plastic bases and mounting plates reduce overall weight. This composite construction resolves the contradiction by using each material where it provides the most benefit - metal for structural integrity during forming, plastic for weight reduction in non-critical components.
2Strength
If metal bases and mounting plates are used in match dies, then strength and heat resistance are improved, but cost increases
Solution Approach 1:
The patent reduces cost by using composite materials - metal forming plates combined with plastic bases and mounting plates. The plastic components are less expensive than metal and can be manufactured through additive manufacturing, reducing overall tooling cost while maintaining necessary strength through the metal forming plates.
Solution Approach 2:
The patent changes the material parameter from all-metal construction to a hybrid metal-plastic construction. This parameter change reduces cost by substituting expensive metal components with cheaper plastic alternatives in non-critical areas, while maintaining strength where required through the metal forming plates.
3Temperature
If steam heating is used for forming plates, then panel formation is enabled, but heat transfer loss increases
Solution Approach 1:
The patent extracts the heating function from the base and mounting plate components, concentrating it only in the forming plates where it is needed. By placing heating elements directly in the forming plates and using plastic bases that do not conduct heat, the system eliminates unnecessary heat transfer loss to non-critical components while maintaining necessary temperature for panel formation.
Solution Approach 2:
The plastic base acts as a thermal intermediary that blocks heat transfer from the heated forming plates to the mounting plates and other non-critical components. This intermediary material allows the system to maintain high temperatures in the forming plates while preventing heat loss to surrounding structures, resolving the energy loss contradiction.
4Reliability
If all-metal match dies are used, then durability is improved, but tool storage and transportation complexity increases
Solution Approach 1:
The patent uses composite materials to reduce weight while maintaining durability. The metal forming plates provide the necessary durability for panel formation, while the plastic bases and mounting plates reduce overall weight, simplifying storage and transportation requirements without compromising the durability needed for reliable operation.
