Hinged Drywall Panels and Flaps for Rapid Corner Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The finishing process of drywall corners, especially inner and outer corners, is time-consuming and skill-dependent, leading to increased construction costs and labor time, particularly for DIY individuals.
Innovation Solution
A hingeable drywall apparatus with gypsum-containing segments connected by a hinge, allowing for easy formation of inner and outer corners through a groove and reinforcement with non-metallic strengthening materials, enabling quick and easy corner construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional drywall corner finishing process is used, then corner joints can be formed, but the process is time-consuming and requires high skill level
Solution Approach 1:
The drywall board is segmented into two separate boards, each with a tapered edge. These segmented boards can be easily joined at corners without requiring complex finishing procedures, thus improving productivity and reducing skill requirements.
Solution Approach 2:
The tapered edges are pre-formed on the drywall boards during manufacturing. This preliminary action eliminates the need for on-site corner shaping and finishing work, allowing quick assembly by individuals with minimal skill.
2Ease of manufacture
If traditional corner finishing process is used, then corner joints can be completed, but labor time and construction costs increase
Solution Approach 1:
Dividing the drywall into segmented boards with pre-formed tapered edges simplifies the manufacturing process and enables rapid corner assembly, significantly reducing finishing time and labor costs.
Solution Approach 2:
The drywall boards are designed to be self-finishing through their tapered edges, which automatically create the necessary corner profiles when joined. This eliminates the need for additional finishing operations by workers.
3Strength
If metal corner sections are used for outer corners, then corner structure is reinforced, but installation complexity and time increase
Solution Approach 1:
The metal corner sections are extracted and replaced with simplified drywall boards featuring tapered edges. This removal of complex metal components reduces installation complexity while maintaining adequate corner strength through the engineered paper-gypsum-paper structure.

AI summary
A drywall system is provided including a first drywall panel and a second drywall panel connected to the first drywall panel via a main hinge. A first drywall flap connected to the first drywall panel via a first hinge, and a second drywall flap connected to the second drywall panel via a second hinge. The first drywall panel, the second drywall panel, the first drywall flap and the second drywall flap can hinge to assume at least one corner configuration in which the first and second flaps lie on a first plane, the first drywall panel lies on a second plane and the second drywall panel lies on a third plane, such that the first plane, the second plane and the third plane are mutually orthogonal. A coating can be provided on an external surface of the framing drywall liner for strengthening the groove which, in embodiments can be polyester strip that extends over portions of the first and second gypsum-containing segments on either side of the of the groove.
