Plasterboard Panel With Foldable Core Cutout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in handling and transporting plasterboards due to their large size and weight, which makes them cumbersome for vertical partitions and construction sites.
Innovation Solution
A plasterboard design featuring a cardboard sheet with a straight cut from one edge to the opposite edge, allowing the core to be broken along the cut, enabling the two parts to pivot and reducing the overall length, with the cut optionally covered in glue and reinforced cardboard sheets for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plasterboards are made with large size to produce vertical partitions without arranging two boards one above the other, then productivity is improved, but handling and transportation become difficult
Solution Approach 1:
The plasterboard is divided into two equal halves by a cut through the core, allowing the board to be folded into a compact configuration for easy transportation while maintaining full size for efficient vertical partition installation. The cut enables the board to be segmented into manageable portions that can be handled separately during transport but assemble to form the complete panel during installation.
Solution Approach 2:
The plasterboard transitions from a static rigid structure to a dynamic configurable structure. The cut allows the board to change its configuration between a flat extended state for installation and a folded compact state for transportation. The core material provides the necessary flexibility to bend along the cut line while maintaining structural integrity during both states.

3Ease of operation
If a cut is made in the cardboard sheet to allow breaking and pivoting, then handling and transportation are facilitated, but structural integrity may be compromised
Solution Approach 1:
The cut is made only in the cardboard sheet while leaving the core material intact. This localized modification allows the cardboard to be separated and folded without compromising the structural integrity of the core. The core maintains its full strength and rigidity, while the cardboard provides the necessary flexibility for folding and handling.
Solution Approach 2:
The plasterboard is divided into two equal halves by a cut through the core, allowing the board to be folded into a compact configuration for easy transportation while maintaining full size for efficient vertical partition installation. The cut enables the board to be segmented into manageable portions that can be handled separately during transport but assemble to form the complete panel during installation.

AI summary
A facing panel, in particular a plasterboard panel (2), according to the invention comprises a core (4) arranged between two cardboard sheets (6, 8). One cardboard sheet (8) has a substantially straight cutout (12) extending from one edge of the panel to an opposite edge. The invention also provides that the core (4) has a break (14) across its full thickness, and that the cardboard sheet (6) opposed to the cut-out sheet (8) is folded at approximately 180° along the break (14).
