Spline Joint Partition Wall for Screw-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for building partition walls and wall linings require extensive cutting and screwing of metallic studs, which is time-consuming and requires professional skills, making it difficult for amateur carpenters to install them effectively.
Innovation Solution
A kit-of-parts system that includes U-profile tracks and z-profile beams with beam slits, allowing for interlocking without screws, and boards with grooves that form spline joints, enabling easy assembly by reducing the need for cutting and screwing, and allowing for installation by moderately trained DIYers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metallic studs are used with traditional screwing methods, then the partition wall structure is strong and stable, but the installation process becomes time-consuming and requires professional skills
Solution Approach 1:
The patent replaces the traditional screwing mechanical system with a spline joint system. The spline profile engages with grooves in the boards to provide mechanical coupling, eliminating the need for screws while maintaining structural integrity. This substitution simplifies the installation process by removing the need for drilling and fastening operations.
Solution Approach 2:
The metallic studs are designed with self-aligning features where the spline profile automatically engages with the grooves in the boards during assembly. The design allows for self-correction of minor positioning errors and automatic seating, enabling amateur installers to achieve proper alignment without specialized skills or tools.
2Adaptability or versatility
If extensive cutting of metallic studs is performed, then the partition wall can be customized to fit specific spaces, but the installation time increases significantly
Solution Approach 1:
The partition wall system is divided into modular components with standardized dimensions. The metallic studs, U-profile tracks, and boards are designed as discrete modules that can be assembled in various configurations. This segmentation allows customization of the overall wall layout without requiring cutting of individual components, maintaining both adaptability and installation speed.
Solution Approach 2:
The metallic studs are pre-formed with spline profiles and pre-cut to standard lengths during manufacturing. This preliminary preparation eliminates the need for on-site cutting and shaping operations, allowing installers to simply assemble the pre-prepared components to achieve the desired wall configuration.
3Strength
If multiple screws are used to fix boards to the frame, then the connection is secure and durable, but the number of fastening operations increases
Solution Approach 1:
The patent replaces multiple screw fastenings with a single spline joint connection. The spline profile on the metallic stud engages with the groove in the board to provide both vertical and lateral connection strength, eliminating the need for multiple screws while reducing the number of fastening operations from several per board to a single insertion action.
Solution Approach 2:
The patent combines multiple fastening functions into a single integrated spline joint. The same spline profile that provides vertical support also provides lateral stability and positional alignment, merging what would traditionally require separate screws for each function into one unified connection mechanism.

AI summary
The present invention concerns a permanent drywall comprising, a support structure formed by • top and bottom U-profile tracks (2u, 2d) comprising first and second U-flanges, which are fixed to a ceiling and a floor, respectively, extending along a longitudinal axis (X), • i-profile beams (3) comprising a beam web (3w) sandwiched between first and second beam flanges (3f1, 3f2) coupled to the first U-flange of the top U-profile track (2u) by insertion of a beam slit (3s) provided at a free end of he beam web (3w), such as to extend normal to the top U-profile tracks along a vertical axis (Z), the first beam flange (3f1) is located outside of the top U-profile tracks. Rectangular boards (1) are fixed to the support structure. The boards comprise first and second vertical edges parallel to the vertical axis (Z) and provided with a groove (1g) running along the whole height (H1) of the boards. The boards are held in place between two between two i-profile beams (3) by spline joints formed by the first beam flange (3f1) being inserted in the grooves of two adjacent boards. A drywall according to the present invention is very simple to install.
