Slot Drain Connecting Device for Channel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slot channels for surface drainage require precise alignment of slot-shaped inflow openings during installation, which is complex and labor-intensive, especially with narrow openings, and existing solutions are cumbersome and costly.
Innovation Solution
A connecting device with a base body and a movably attached bridge body, featuring a swivel joint, that fits directly into the inflow opening of adjacent channel bodies, allowing for easy alignment and flush connection, even if the channel bodies are not perfectly aligned, providing maximum stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional slot channels are laid without additional alignment measures, then the installation process is simple, but the inflow openings become misaligned and optically disturbing
Solution Approach 1:
A connecting device serves as an intermediary element between adjacent channel bodies. This connector includes a base body that attaches to one channel body and an extension body that extends into the inflow opening of the adjacent channel body, providing automatic alignment without requiring complex external alignment measures during installation.
Solution Approach 2:
The connecting device is nested within the inflow opening of the channel body. The extension body of the connector is received within the inflow opening of the adjacent channel body, allowing the alignment mechanism to be integrated within the existing structure rather than requiring external alignment fixtures.
2Manufacturing precision
If additional alignment measures are used to ensure precise inflow opening alignment, then the alignment precision improves, but the installation effort and time increase
Solution Approach 1:
The connecting device is pre-assembled with the channel body during manufacturing, with the extension body already positioned to receive the connector from the adjacent channel. This preliminary preparation eliminates the need for complex alignment operations during installation, as the components are designed to fit together automatically.
Solution Approach 2:
The connecting device enables self-aligning installation through its geometric design. The extension body fits into the inflow opening at a specific angle and position, causing automatic alignment when the channel bodies are brought together, eliminating the need for external alignment tools or procedures.
3Manufacturing precision
If the connecting device is designed to fit precisely into the inflow opening, then the alignment precision improves, but the device complexity increases
Solution Approach 1:
The connecting device is segmented into two functional parts: a base body that attaches to one channel body and an extension body that extends into the adjacent channel body's inflow opening. This segmentation allows each part to be optimized for its specific function while keeping the overall design simple and manufacturable.
Solution Approach 2:
The connecting device serves multiple functions simultaneously: it provides mechanical connection between channel bodies, ensures precise alignment of inflow openings, and facilitates easy installation through its self-aligning geometry. This multi-functionality reduces the need for separate alignment devices or procedures.
