Gypsum Repair Plug With Recesses for Plasterboard Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for repairing plasterboards, such as using joint compound to fill holes, are tedious and require multiple layers that shrink upon drying, making the process time-consuming and inefficient.
Innovation Solution
A cylindrical repair plug with longitudinal or spiraling recesses made from gypsum plaster or similar materials, which can be twisted or screwed into place using a fluid to secure it, allowing for a single-layer application and easy insertion into holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If joint compound is used to fill holes in plasterboards, then the holes can be sealed, but the process becomes tedious and time-consuming due to multiple layers being required
Solution Approach 1:
The repair system is segmented into a separate plug component and a fastening joint compound. The plug provides the structural filling function while the joint compound provides only the fastening function, eliminating the need for multiple layers of compound and reducing repair time.
Solution Approach 2:
The plug acts as an intermediary component between the hole and the joint compound. It provides a stable base that eliminates the need for bulk compound layers, allowing the joint compound to focus solely on fastening and finishing.
2Reliability
If multiple layers of joint compound are applied to fill holes, then adequate sealing is achieved, but the process requires repeated drying time between applications
Solution Approach 1:
The function of sealing is separated from the function of fastening. The plug provides immediate structural sealing without requiring drying time, while the joint compound applies only as a thin fastening layer that dries quickly.
Solution Approach 2:
The plug is inserted into the hole before applying joint compound, providing immediate structural support and sealing. This preliminary action eliminates the need for multiple layers of compound and their associated drying times.
3Ease of operation
If a solid plug without recesses is used, then insertion is difficult and tight fit is hard to achieve, but adding recesses increases manufacturing complexity
Solution Approach 1:
The plug incorporates recesses that allow joint compound to penetrate and create a mechanical interlock. This simple geometric feature enables easy insertion and secure fastening without complex structures or additional components.
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
Enables quick and effective sealing of holes with a single layer of joint material, reducing the time and effort required for repairs while ensuring a snug fit and easy insertion, resulting in a nearly invisible finish after painting.
Implementation Method 1
This plug is fastened in the hole with the use of a fluid/liquid which is absorbed by the material of the plug, thus fastening it in the hole.
