V-Shaped Elastic Coupling Element for Inverted T Profile Stress Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling elements for bar-shaped inverted T profiles lack sufficient resistance to stresses in both parallel and transverse directions, which compromises the stability and structural integrity of false ceiling lattice structures.
Innovation Solution
A metal coupling element with a specifically designed geometry, comprising a rectangular portion, a lesser height portion, a V-shaped elastic appendix, and a toothed surface, is applied to the central rib of the T profile by clinching, allowing for secure engagement with other profiles to enhance stability and resistance to stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional coupling elements are used for inverted T profiles, then the structure can be assembled, but the resistance to stresses in parallel and transverse directions is insufficient
Solution Approach 1:
The coupling element is divided into multiple functional portions: a first portion for engagement with the central rib, a second portion extending perpendicular to the first, and a third portion forming a V-shaped elastic appendix. This segmentation allows each portion to specifically address different stress directions and engagement requirements, thereby improving overall strength and reliability.
Solution Approach 2:
The V-shaped elastic appendix is designed to be flexible and deformable, allowing it to dynamically adapt to stress loads. The elastic portion can deflect under transverse stresses and return to its original position, providing dynamic resistance to both parallel and transverse stresses while maintaining structural integrity.
2Strength
If the coupling element uses a complex geometry with multiple portions and features, then the resistance to stresses improves, but the manufacturing complexity increases
Solution Approach 1:
The coupling element utilizes changes in geometric parameters, particularly the V-shaped elastic appendix with specific angle and dimensions, to achieve high stress resistance. By optimizing these parameters during design, the element provides enhanced strength while remaining manufacturable through standard metal forming processes.
Solution Approach 2:
The coupling element is made of metal material that combines strength and elasticity. The metallic material allows the complex geometry to be manufactured with appropriate mechanical properties, achieving both high stress resistance and manufacturability through material selection.
3Ease of operation
If the coupling element is made as a separate piece applied by clinching, then the assembly process is simplified, but the connection strength may be compromised
Solution Approach 1:
The coupling element is designed with pre-formed engagement features including the V-shaped elastic appendix and notches that are prepared in advance during manufacturing. These preliminary actions ensure that when the element is applied by clinching, the connection achieves maximum strength without requiring complex assembly operations.
Solution Approach 2:
The coupling element acts as an intermediary component between the central rib and the lattice structure. Its specially designed geometry with multiple portions and elastic appendix provides a strong connection interface that simplifies assembly while maintaining high connection strength through its mediating function.
