Trench Drain Frame Segmentation for Substrate Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trench drains face challenges in effectively distributing load and securing to substrates, leading to potential instability and inadequate support during installation and use.
Innovation Solution
The design incorporates a frame with a lower surface that is either unsupported by the channel or directly engages the substrate, along with support ribs and clamps that extend laterally to secure the frame to the substrate, enhancing load distribution and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the frame is fully supported by the channel, then the installation is simpler, but the load distribution and stability are insufficient
Solution Approach 1:
The frame's lower surface is divided into two functional zones: a first portion that contacts the channel for simplified installation, and a second portion that is spaced from the channel to directly engage the substrate for improved load distribution and stability. This segmentation allows the frame to simultaneously achieve easy installation and reliable structural performance.
2Strength
If the frame directly engages the substrate, then the load-bearing capacity increases, but the installation complexity increases
Solution Approach 1:
The frame is segmented into portions with different functions: one portion simplifies installation by contacting the channel, while another portion enhances load-bearing capacity by directly engaging the substrate. This segmentation resolves the contradiction between installation ease and structural strength.
Solution Approach 2:
The frame serves multiple functions simultaneously: it provides structural support, distributes loads, and facilitates installation. The multi-functional design allows the single component to achieve both simplified installation and enhanced load-bearing capacity without requiring additional separate elements.
3Reliability
If support structures are added to enhance stability, then the reliability improves, but the device complexity increases
Solution Approach 1:
The support structures (support ribs and clamps) are merged with the frame to form an integrated assembly. This combination provides enhanced stability and reliability while avoiding the complexity of separate, independently installed support components. The unified design maintains structural integrity without proportionally increasing complexity.

AI summary
Trench drains are installed in indoor or outdoor locations and provide drainage for water and/or other liquids. Trench drains are elongated, having a length that is generally longer than a width. A trench drain includes a channel, a frame, and a drain cover. The channel can receive and direct water and/or other liquids that have entered the drain via the drain cover. The drain cover is supported by the frame, which is mounted to the channel.
