Connection element for connecting with rectangular ducting components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connecting rectangular ducting components is time-consuming, expensive, and prone to leakage and structural vulnerabilities due to uneven force distribution, especially under pressure loads, which existing solutions like flanged couplings and multiple hardware components fail to address effectively.
Innovation Solution
A one-piece connection element with lip elements that clamp the ducting components, allowing for easy sliding insertion and sealing without additional hardware, providing reinforcement and maintaining structural integrity under pressure loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple hardware components (flanges, corner pieces) are used to connect rectangular ducting components, then the connection can be achieved, but the installation becomes time-consuming and expensive, and leakage vulnerability increases
Solution Approach 1:
The patent combines multiple separate hardware components (flanges and corner pieces) into a single integrated connection element. This connection element has a U-shaped cross-section that forms a complete frame structure, eliminating the need for multiple separate parts and reducing installation complexity while maintaining sealing reliability
Solution Approach 2:
The connection element is designed with a U-shaped cross-section that can be segmented into a back plate and side plates, allowing for simplified manufacturing and assembly while maintaining the overall structural integrity and sealing capability of the connection
2Volume of stationary object
If rectangular ducting components are used to save space, then the space occupation is reduced, but the components become vulnerable to deflecting under pressure load due to uneven force distribution
Solution Approach 1:
The connection element applies local reinforcement at the connection points between ducting components. The rigid frame structure of the connection element provides localized structural support where forces are concentrated, strengthening the connection without requiring the entire ducting component to have increased wall thickness
Solution Approach 2:
The connection element features rounded inner corners in its U-shaped cross-section, which help distribute stress more evenly compared to sharp corners. This curvature design reduces stress concentration points that would otherwise be vulnerable to deflecting under pressure loads
3Ease of operation
If traditional flanged couplings with sliding strips and screws are used, then ducting components can be joined, but the installation process becomes complex and prone to leakage
Solution Approach 1:
The connection element incorporates an elastic sealing profile that automatically adapts to the ducting component surfaces upon insertion. The elastic material deforms to fill gaps and creates a seal without requiring additional sealing components or complex adjustment procedures, making the installation simple while ensuring reliable sealing
