Fabric Hinge Construction for Top-Down Overhead Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods require building structures from the ground up, necessitating extensive use of temporary and permanent supports, which are labor-intensive and inefficient.
Innovation Solution
A method involving the use of a flexible fabric suspended in a vertical orientation, treated with a visco-elastomeric fixative to create a fixed overhead structure (FOS) that serves as a hinge for rotating into position, eliminating the need for traditional supports and allowing construction from the top down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If construction is performed from the ground up using traditional methods, then structural stability is achieved, but labor intensity and construction time increase significantly
Solution Approach 1:
The patent inverts the traditional construction sequence by building from the top down rather than from the ground up. The flexible fabric is first positioned in its final location, then the fixative is applied to secure it, eliminating the need for temporary supports and significantly reducing construction time and labor intensity.
Solution Approach 2:
The flexible fabric is pre-positioned in its final location before the fixative is applied. This preliminary positioning allows the structure to be secured in its intended configuration without requiring additional temporary support elements, thereby simplifying the overall construction process.
2Reliability
If temporary supports are used during construction, then structural stability is maintained, but material costs and labor requirements increase
Solution Approach 1:
The patent extracts and eliminates the temporary support structures from the construction process. By applying the fixative to the flexible fabric in its final position, the need for temporary supports is completely removed, reducing material consumption and associated labor costs while maintaining structural stability.
Solution Approach 2:
The flexible fabric serves its own structural support function by being positioned and secured in its final location without requiring external temporary supports. The fixative application process itself provides the necessary structural stability, making the system self-sufficient.
3Strength
If multiple layers are added to increase load-bearing capacity, then structural strength is improved, but construction complexity and time increase
Solution Approach 1:
The patent changes the parameters of the fixative application process, using a visco-elastomeric fixative that provides high load-bearing capacity through its material properties rather than through multiple layers. This single-layer approach with optimized fixative application achieves the required structural strength while maintaining construction efficiency.

AI summary
A method of fabricating a structure including hanging a flexible fabric in a substantially vertical direction, shielding a portion of the flexible fabric and applying a fixative to an unshielded portion of the flexible fabric, thereby forming a fixed portion of the flexible fabric. A shielded portion of the flexible fabric is located in a portion of the fabric and is configured to act as a hinge allowing the fixed portion to be rotated.
