Triangular Rail Stringer with Reinforced Zones for False Wall Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of false wall slabs is challenging due to deformation of the frame under tension from the canvas during the cooling phase after gluing, and existing solutions are either costly, complex, or difficult to implement, especially when removing the canvas.
Innovation Solution
A tubular stringer with a substantially triangular section and reinforced zones along the side, upper, and connecting walls, featuring grooves for the canvas, which provides mechanical strength and resistance to tension without the need for pre-bending, allowing for a simpler and more robust frame structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If pre-bending profiles before attaching canvas is used, then frame deformation is compensated, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The rail body is pre-formed with integrated reinforcement portions (solid areas) during manufacturing, rather than requiring pre-bending operations. This preliminary structural preparation allows the frame to resist deformation automatically when canvas tension is applied, eliminating the need for complex pre-bending procedures while maintaining frame stability.
Solution Approach 2:
The rail body incorporates localized solid areas (reinforcement portions) at specific positions along the profile, particularly in regions susceptible to deformation. This local strengthening provides targeted structural support where needed, maintaining overall frame stability without requiring complex global modifications to the entire profile structure.
2Stability of the object's composition
If pre-bending profiles is performed, then canvas tension deformation is compensated, but production time and cost increase
Solution Approach 1:
The reinforcement portions are integrated into the rail body during initial manufacturing, performing the structural preparation in advance. This eliminates the need for time-consuming pre-bending operations in the production line, as the rails are already optimized to resist canvas tension deformation when assembled into the frame.
3Stability of the object's composition
If continuous prestressing means are applied, then frame deformation is prevented, but structural complexity increases
Solution Approach 1:
Instead of applying continuous prestressing means throughout the frame structure, the invention uses localized solid areas within the rail body cross-section. These reinforcement portions provide targeted structural strength at critical locations, preventing deformation without requiring complex external prestressing devices or mechanisms.
4Force
If traditional gluing method is used, then canvas is attached to profiles, but canvas removal becomes difficult
Solution Approach 1:
The attachment system is segmented into modular components: the rail body with integrated grooves and the canvas with harpoon-shaped edges. This segmentation allows the canvas to be mechanically engaged with the grooves for strong attachment during use, while enabling easy disengagement and removal when needed, overcoming the permanence issue of traditional gluing.
