Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional top-plate members with artificial marble stone decorations are excessively heavy, making them difficult to handle and install, requiring multiple workers and heavy machinery, which is time-consuming and often impractical.
Innovation Solution
A lightweight decorative panel is designed with a decorative stone plate as the main surface and a framing stone material surrounding an opening, combined with a porous formed-material, such as a lightweight cementitious panel with dispersed bubbles and reinforcing fibers, to maintain strength and appearance while reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a top-plate member is made of artificial marble stone decoration, then the appearance and strength are improved, but the weight becomes excessively heavy making it difficult to handle and install
Solution Approach 1:
The panel is divided into multiple layers including a decorative stone plate layer, a lightweight core layer, and a backer layer. This segmentation allows the decorative function and structural function to be separated, enabling weight reduction while maintaining appearance and strength.
Solution Approach 2:
The panel uses a composite structure combining decorative stone plates with lightweight materials such as foam or honeycomb core. This composite approach maintains the aesthetic and structural benefits of stone while significantly reducing the overall weight for easier handling and installation.
2Ease of manufacture
If heavy machinery and rollers are prepared for installation, then the top-plate member can be installed, but the preparation becomes time-consuming and complex
Solution Approach 1:
By segmenting the panel into lighter composite layers, the overall weight is reduced to a level that does not require heavy machinery for installation, thereby reducing preparation time and simplifying the installation process.
Solution Approach 2:
The weight parameter of the panel is changed through material selection and structural design, transforming it from a heavy stone slab to a lightweight composite panel that can be installed with minimal equipment and preparation.
3Weight of moving object
If the top-plate member is light-weighted, then the ease of handling is improved, but the strength may be reduced
Solution Approach 1:
The composite structure combines lightweight core materials with strong decorative stone plates and backer layers, achieving weight reduction while maintaining or even enhancing overall panel strength through the synergistic combination of materials.
Solution Approach 2:
The panel structure is designed with multiple layers in the thickness dimension, distributing loads across different layers. This dimensional approach allows the front decorative layer to be thin and light while the backer and core layers provide structural strength.
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 panel is easier to handle and install, reducing the need for multiple workers and heavy machinery, while maintaining strength and appearance, facilitating improved workability at construction sites.
Implementation Method 1
a porous formed-material in a shape of a plate, which is comprised of a porous lightweight cementitious panel wherein a bubble(s) and a reinforcing fiber(s) are dispersed in a cured-cementitious material
