Solution Overview

Problem

Cork panels are underutilized in interior decoration due to their perceived low aesthetic impact, while stone materials offer a desirable appearance but come with high environmental impact and unfavorable physical properties compared to cork.

Innovation Solution

A cork-based panel is treated with cementitious materials and paints to mimic the aesthetic appearance of stone, involving a process where one face is stabilized with adhesives and the exposed face is textured and painted to create a stone-like effect, balancing cork's mechanical properties with stone's appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If stone materials are used for interior decoration, then aesthetic appearance is improved, but environmental impact increases and physical properties deteriorate (high hardness, heat conduction, density)

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidenvironmental impact
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent applies the copying principle by creating a cork-based panel that replicates the aesthetic appearance of stone through surface treatment. The cork panel is treated with cementitious materials and paints to mimic stone's visual characteristics while maintaining cork's beneficial physical properties, thus achieving the desired aesthetic without the environmental harm of actual stone extraction

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent uses composite materials by combining cork with cementitious materials and paints to create a hybrid surface that exhibits stone-like appearance. The composite structure integrates cork's lightweight and insulating properties with the aesthetic qualities of stone, resolving the contradiction between appearance and environmental impact

Inventive Principle:
Principle #40Composite materials

2Shape

If stone materials are used for interior decoration, then aesthetic appearance is improved, but physical properties worsen (extremely hard, heat-conducting, high density)

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidheat conduction
Core Design Contradiction:
ShapeVSTemperature

Solution Approach 1:

The patent copies only the aesthetic visual properties of stone through surface treatment of cork, while deliberately maintaining cork's superior thermal insulation properties. The cementitious treatment and painting create stone-like appearance without replicating stone's heat conduction, thus resolving the contradiction between aesthetic appearance and thermal performance

Inventive Principle:
Principle #26Copying

3Object-affected harmful factors

If cork panels are used for interior decoration, then environmental sustainability is improved and physical properties are maintained, but aesthetic appearance deteriorates (perceived low aesthetic impact)

Engineering Contradiction:
Improveenvironmental sustainabilityVSAvoidaesthetic appearance
Core Design Contradiction:
Object-affected harmful factorsVSShape

Solution Approach 1:

The patent applies color changes by treating the cork surface with cementitious materials and paints that mimic the coloration and visual texture of stone. This surface treatment transforms the appearance of cork panels, giving them a stone-like aesthetic while preserving the underlying cork material's environmental sustainability

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent copies the aesthetic characteristics of stone onto cork surfaces through chemical and physical treatment processes, enabling cork panels to achieve stone-like visual impact while maintaining cork's environmental benefits

Inventive Principle:
Principle #26Copying

AI summary

The invention is directed to a process for the production of a cork-based panel with stone effect, the process comprising the following steps: a) treating a first face of a cork-based panel, corresponding to the face intended for contact with a wall on which the panel will be installed, with a material chosen from the following: hardening material based on aerial and/or hydraulic cement mortars, single and two-component stuccoes for stone or metals, glues for stone materials; b) letting the first face dry; c) treating the second face intended to remain exposed with one of the materials described in step a, where the two materials used in steps a. and c. may be equal or different; d) letting the second face dry; e) sanding both sides to remove excess material wherein the second face is treated in such a way that on part of the second face cork surface appears, creating on said second face areas with cork surface and areas with cementitious material surface; f) painting the second face with one or more layers of one or more materials chosen from water-based enamels, acrylic enamels, water-based paints, acrylic paints.
