Solution Overview

Problem

Existing technologies for manufacturing stone material articles with low thickness face limitations in material compactness and delamination, particularly with ceramic materials, and lack aesthetic fidelity and mechanical strength.

Innovation Solution

A process involving arranging a block or sheet of natural stone or ceramic materials, gluing a flexible support, cutting to achieve a minimum thickness, winding into irregular shapes, and impregnating with polymeric materials to create laminated panels with enhanced mechanical hardness and aesthetic appeal, allowing for easy installation and thermal insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If stone material plates are cut to low thickness (3-5mm), then the weight and material consumption are reduced, but the mechanical strength and structural integrity deteriorate

Engineering Contradiction:
ImproveweightVSAvoidmechanical strength
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent applies composite materials by combining thin stone plates (3-5mm) with a flexible support structure and adhesive layers. This creates a composite laminate structure where the thin stone provides aesthetic value while the support structure provides mechanical strength, resolving the contradiction between reduced weight and maintained strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent uses a flexible support structure (flexible shell) that can be wound around cylindrical supports during production. This flexible support maintains the structural integrity of thin stone plates while allowing them to be handled and installed, enabling both low thickness and adequate mechanical strength.

Inventive Principle:
Principle #30Flexible shells and thin films

2Loss of substance

If stone material plates are cut to low thickness (3-5mm), then the material consumption is reduced, but the structural integrity and resistance to damage worsen

Engineering Contradiction:
Improvematerial consumptionVSAvoidstructural integrity
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

By creating a composite laminate with thin stone plates bonded to a flexible support structure, the patent achieves both reduced material consumption (thin plates) and maintained structural integrity (through the composite structure and adhesive bonding).

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies adhesive layers to the stone plates before assembly and pre-assembles the laminate structure before final installation. This preliminary bonding action ensures structural integrity is established before the product is put into service, preventing damage during handling and installation.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If adhesive materials are applied to stone surfaces, then the bonding and assembly are facilitated, but the surface aesthetics and natural appearance may deteriorate

Engineering Contradiction:
Improvebonding easeVSAvoidsurface aesthetics
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent applies adhesive materials locally at the edges and bonding surfaces of the stone plates rather than covering the entire surface. This localized application facilitates assembly while preserving the natural aesthetic appearance of the visible stone surfaces.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The flexible support structure serves as a temporary carrier that is removed after the laminate is assembled. This allows adhesive materials to be applied effectively during manufacturing without permanently affecting the final aesthetic appearance, as the support itself is not visible in the finished product.

Inventive Principle:
Principle #26Copying
