Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technical textiles lack flexibility and malleability while supporting high loads, and existing combinations of textiles and metals for reinforcement or insulation are either too rigid or not designed for flexible, shape-changing applications.
Innovation Solution
A method combining a flexible woven or nonwoven textile with a malleable aluminum sheet, using a reactive polyurethane glue to secure them, allowing for the creation of a flexible, stress-resistant, and water-resistant textile-reinforced material that can be shaped and decorated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal sheets are combined with textile substrates for reinforcement or insulation, then strength and load-bearing capacity are improved, but flexibility and malleability deteriorate
Solution Approach 1:
The patent uses thin metal sheets (foil) instead of rigid metal plates, allowing the material to bend and conform to shapes while maintaining strength. The thin film approach enables flexibility and malleability to be retained even with metal reinforcement
Solution Approach 2:
The invention creates a composite material system combining textile substrates with metal foil layers and adhesive films. This multi-layer composite structure integrates the strength of metal with the flexibility of textile, achieving both load-bearing capacity and formability
2Use of energy by stationary object
If metal layers are combined for insulation purposes, then thermal insulation is improved, but adaptability for shape-changing applications deteriorates
Solution Approach 1:
The use of thin metal foil layers provides thermal insulation while maintaining flexibility. The thin film structure allows the material to be shaped and reconfigured without rigid constraints, enabling both insulation and adaptability
Solution Approach 2:
The patent enables dynamic shape-changing capability through the flexible construction of the material. The combination of textile and thin metal foil allows the structure to adapt to different configurations while maintaining insulating properties
3Strength
If adhesive pads with fibrous layers are used to join metal layers, then joining strength is improved, but flexibility of the final product deteriorates
Solution Approach 1:
The patent uses thin adhesive films instead of thick fibrous adhesive pads. This thin film approach maintains joining strength while preserving the flexibility of the overall structure, avoiding the rigidity introduced by thick adhesive layers
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 resulting material is highly flexible, capable of supporting heavy loads and undergoing various artistic processing while maintaining non-flammability and resistance to moisture, temperature, and mechanical stress.
Implementation Method 1
a glue is affixed over the entire apparent surface of the textile support positioned on the workbent. The glue is deposited on the support by means of a helical cylinder, at a rate of 30 to 40 grams per square meter, so as to form a homogeneous and uniform film
Implementation Method 2
The method according to the invention can further be optimized using an annealing aluminum sheet, i.e., having undergone heat treatment for modifying the mechanical properties of the original material, to improve malleability
