Multi-Film Cladding Panel Simulating Stone Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation materials like polystyrene and polyurethane are soft, prone to moisture absorption, and lack durability and aesthetic appeal, making them difficult to integrate with materials like marble or stone for exterior cladding, while existing solutions face issues with cracking, weight, cost, and thermal bridging.
Innovation Solution
A cladding system comprising multi-film layers that simulate the appearance of brick, stone, or marble, with a transparent external film, a granular film, and a base insulating layer, allowing for coordinated sizing and grout simulation without visible seams, and featuring a method to produce panels with controlled thickness for desired R-value and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real stone or brick is used for exterior cladding, then aesthetic appeal and durability are improved, but weight and installation complexity increase significantly
Solution Approach 1:
The patent creates artificial stone panels that visually replicate the appearance of natural stone through multi-film layering. The external transparent film combined with granular film and support film reproduces the texture, color variations, and visual characteristics of natural stone without using actual stone material, thereby eliminating the weight problem while maintaining aesthetic appeal and durability
Solution Approach 2:
The invention uses composite material construction with multiple film layers bonded together. The external transparent film, granular film containing pigment particles, and support film create a composite structure that combines the benefits of each layer: transparency and protection from the external film, texture and color from the granular film, and structural support from the support film, achieving both lightweight construction and stone-like appearance
2Use of energy by moving object
If rigid foam insulation is installed on exterior walls, then insulation performance is improved, but moisture absorption and deterioration risk increase
Solution Approach 1:
The patent applies multiple thin film layers over the rigid foam insulation to create a protective barrier. The external transparent film and granular film form a non-permeable shell that prevents moisture from reaching the insulation material, while still allowing thermal energy to be blocked, thus maintaining insulation performance without moisture absorption risks
3Reliability
If stone veneer is installed directly on rigid insulation, then aesthetic appearance is improved, but installation complexity and cost increase due to reinforcement requirements
Solution Approach 1:
Instead of installing heavy stone veneer that requires reinforcement, the patent creates a lightweight artificial stone panel that replicates the appearance of natural stone. The multi-film construction produces the desired aesthetic effect without the weight, eliminating the need for additional reinforcement layers and simplifying installation while maintaining cost-effectiveness
4Ease of operation
If polyurethane panels are used for faux stone, then ease of installation is improved, but mechanical resistance and durability decrease
Solution Approach 1:
The patent enhances the mechanical resistance of polyurethane panels by creating a composite structure with multiple film layers. The external transparent film provides a hard protective surface, the granular film adds structural integrity, and the support film reinforces the overall panel, thereby increasing mechanical resistance while maintaining the ease of installation benefits of polyurethane
