Perforated Gypsum Boards With Spacer Elements For Joint Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling gypsum-based perforated boards in suspended ceilings or walls are labor-intensive and costly due to the need for precise alignment, which can be time-consuming and requires two people, and they lack effective joint strength and damage resistance, especially when using seamless butting methods.
Innovation Solution
The use of prefabricated spacer elements made of materials like metal or plastic, attached to the perforated boards, which define the joint width and provide high joint strength by being designed to match the hole pattern, allowing for easier alignment and filling without exposing edges to damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional alignment tools and methods are used for assembling perforated boards, then optical requirements can be met, but assembly time and labor costs increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-attaching spacer elements to the perforated boards during manufacturing. These spacers are positioned at specific locations (e.g., corners or edges) to define the exact spacing and alignment between adjacent boards. During assembly, workers simply need to connect the spacers of adjacent boards, eliminating the need for complex alignment tools and procedures while maintaining precise optical requirements.
2Manufacturing precision
If two people are used for alignment during assembly, then alignment quality improves, but labor costs increase
Solution Approach 1:
The spacer elements are designed to enable self-aligning assembly. The spacers on adjacent boards automatically position themselves relative to each other through simple connection (e.g., interlocking or bolting), allowing a single worker to achieve precise alignment without requiring a second person. The spacer geometry itself provides the alignment function that previously required human skill and coordination.
3Ease of operation
If seamless butting method is used for laying perforated boards, then assembly becomes easier, but joint strength decreases and edges become vulnerable to damage
Solution Approach 1:
The spacer elements serve as intermediary components between adjacent perforated boards. Instead of direct board-to-board contact (seamless butting), the spacers act as mediators that provide both the connection interface and structural reinforcement. The spacers distribute loads and protect the vulnerable board edges while maintaining the seamless appearance from the room side.
4Manufacturing precision
If spacer elements are attached to perforated boards, then alignment precision and joint strength improve, but manufacturing complexity increases
Solution Approach 1:
The alignment and connection function is segmented into separate spacer elements that are attached to the perforated boards. This segmentation allows the spacers to be manufactured independently using simple processes, then attached to the boards in a straightforward manner. The segmentation transforms a complex integrated solution into simple, modular components that reduce overall manufacturing complexity.

AI summary
Perforated gypsum-based boards, in particular perforated gypsum plasterboards or perforated gypsum fibreboards, are provided with spacer elements on at least two side surfaces, which allow straightforward processing to give a ceiling or a wall with the formation of a fixedly predetermined joint width between adjacent perforated boards.
