Segmented Pressing Device for Thin Concrete Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for manufacturing thin concrete articles by pressing a non-hardened concrete composition are not scalable due to the weakness and deformation of thin moulding plates, which prevents the production of stable and beveled-edge products with sufficient material removal at the bottom.
Innovation Solution
A device comprising an upper plate with cavities, a moulding plate with open cavities, and a bottom plate that allows horizontal movement between the upper and moulding plates to control the concrete flow, enabling the production of thin concrete articles with sufficient strength and beveled edges, where the thickness of the upper plate determines the final article thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the moulding plate is made thin to manufacture thin concrete articles, then the thickness of the final article is reduced, but the strength and stability of the moulding plate deteriorates causing deformation and breakage
Solution Approach 1:
The system is divided into three separate functional plates: an upper plate for defining article thickness and shape, a moulding plate for forming the concrete article cavities, and a bottom plate for support and material removal. This segmentation allows each plate to be optimized independently - the moulding plate can be sufficiently thick for strength while the upper plate controls the thin dimension of the final article.
2Length of moving object
If the moulding plate is made thin to produce thin articles, then the article thickness is reduced, but the ability to provide sufficient beveled edge guidance for stamps deteriorates
Solution Approach 1:
The functions of article thickness definition and beveled edge provision are separated. The upper plate defines the thin thickness of the article, while the moulding plate provides the necessary beveled edges for stamp guidance. This segmentation allows the moulding plate to have sufficient thickness for proper beveled edge formation without compromising the thinness of the final article.
3Length of moving object
If the moulding plate is made thin to manufacture thin articles, then the article thickness is reduced, but the ability to remove material at the bottom for proper bottom plate contact deteriorates
Solution Approach 1:
The system separates the functions of article formation and bottom support. The moulding plate can be sufficiently thick to allow material removal at its bottom for proper contact with the bottom plate, while the upper plate controls the thin dimension of the final article. This segmentation resolves the conflict between thin article production and adequate material removal capability.
4Length of moving object
If traditional pressing methods are used with thin moulding plates, then thin articles can be produced, but the productivity and reliability deteriorate due to frequent deformation and breakage
Solution Approach 1:
By dividing the pressing system into three separate plates with distinct functions, the moulding plate can be made sufficiently thick and robust for industrial use without compromising the thinness of the final article. This enables reliable, high-volume production of thin concrete articles that was not possible with traditional single-plate methods.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the cost-effective manufacturing of thin concrete articles by ensuring the moulding plate's strength and allowing for beveled edges and efficient material removal, overcoming the limitations of traditional techniques.

AI summary
Device for pressing a non-hardened concrete composition into a desired form includes an upper plate with first cavities running through the upper plate, a moulding plate with one or more second cavities whereby the upper plate is located directly above the moulding plate, a bottom plate located under the moulding plate whereby the bottom plate closes the one or more second cavities on the bottom, whereby the upper plate and the moulding plate can move horizontally in relation to each other between a first position in which the one or more first cavities are directly and exactly above the one or more second cavities and a second position in which the one or more first cavities are not above the one or more second cavities, wherein the thickness of the upper plate and not the thickness of the moulding plate is decisive for the thickness of the final article.
