Adjustable Fastening Tab for Construction Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foundation screws and adjustable studs do not allow for precise adjustment of construction elements in vertical, horizontal, and angular directions relative to the horizontal plane, making it difficult to level and align elements post-laying, especially on uneven ground surfaces.
Innovation Solution
A fastening tab with a beveled head screw, a metal plate with a beveled aperture, and a flexible joint that allows for vertical and angular adjustment by cooperating to accommodate the screw's position, enabling precise alignment and stabilization of construction elements on foundation screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple foundation screw is used, then the device complexity is reduced, but the adjustment capability (vertical, horizontal, and angular) is insufficient
Solution Approach 1:
The fastening system is divided into separate functional components: a foundation screw for vertical adjustment, a metal plate with beveled aperture for angular adjustment, and a fastening screw for securing the construction element. This segmentation allows each component to perform its specific adjustment function independently, achieving comprehensive adaptability while keeping individual parts relatively simple.
Solution Approach 2:
The invention adds angular adjustment capability (rotation around the vertical axis) to the traditional vertical adjustment foundation screw. The beveled aperture in the metal plate enables the fastening screw to pivot, allowing the construction element to be oriented at different angles relative to the horizontal plane, thus adding a new dimension of adjustability.
2Adaptability or versatility
If adjustable studs with base plates and side walls are used, then the adjustment capability is improved, but the ease of manufacture and installation deteriorates
Solution Approach 1:
The invention extracts the adjustment functionality from a complex integrated stud structure and separates it into simpler components. The foundation screw provides vertical adjustment, while the metal plate with beveled aperture provides angular adjustment. This extraction of functions into separate, simpler components improves ease of manufacture compared to a monolithic adjustable stud.
Solution Approach 2:
Instead of having an adjustable stud with integrated adjustment mechanisms, the invention inverts the approach by using a fixed foundation screw combined with a metal plate that has a beveled aperture. The adjustment capability emerges from the interaction between these two simple components rather than from a complex integrated structure.
3Adaptability or versatility
If foundation screws without angular adjustment are used, then the device complexity is reduced, but the ability to adjust by angle relative to horizontal plane deteriorates
Solution Approach 1:
The metal plate with beveled aperture introduces dynamic adjustability to the system. The fastening screw can pivot within the beveled aperture, allowing the construction element to be angled relative to the horizontal plane. This dynamic capability is achieved through a simple geometric feature (the beveled aperture) rather than a complex mechanical adjustment mechanism.
