Drainage Assembly with Interlocking Flanges to Minimize Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage systems for insulated structures, such as refrigerators, face challenges in securely and efficiently redirecting defrosted liquid, with a need for improved interlocking mechanisms to minimize rotation and ensure effective liquid drainage.
Innovation Solution
A drainage assembly featuring a flexible body with radially extending notches and flanges, where a first drainage tube with receiving flanges is integrated with a second tube having engagement flanges, forming an interlocking arrangement that stabilizes the assembly and facilitates secure liquid redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drainage assembly is installed in an insulated structure, then liquid drainage is enabled, but rotation of the flexible body may occur compromising stability
Solution Approach 1:
The drainage assembly employs a nested flange structure where the first flange is received within a first notch of the flexible body, and the second flange is received within a second notch of the flexible body. This nested arrangement creates multiple levels of mechanical constraint that prevent rotation of the flexible body while maintaining drainage functionality.
Solution Approach 2:
The drainage assembly divides the connection structure into multiple segmented components: the flexible body is separated from the drainage tube, and the drainage tube is further divided into multiple flanges at different positions. This segmentation allows each component to perform its specific function while collectively preventing rotation through distributed mechanical constraints.
2Ease of operation
If the flexible body is made flexible to accommodate installation, then ease of installation is improved, but rotational stability deteriorates
Solution Approach 1:
The flexible body exhibits local quality differentiation where the main body remains flexible to accommodate installation, but specific regions (the notches) provide rigid mechanical constraints. The notches are precisely formed to receive and constrain the flanges, creating localized stability zones that prevent rotation while preserving overall flexibility for installation purposes.
3Stability of the object's composition
If multiple flanges are added to prevent rotation, then rotational stability is improved, but device complexity increases
Solution Approach 1:
The flanges and notches serve multiple functions simultaneously: they provide mechanical constraint to prevent rotation, enable easy assembly through snap-fit engagement, and maintain structural integrity. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity despite the addition of multiple flanges.

AI summary
A drainage assembly for an insulated structure includes a flexible body that has a plurality of flexures and defines an opening and notches that extend radially from the opening. A first drainage tube extends through the opening and includes receiving flanges disposed within the notches defined by the flexible body. A second drainage tube is in fluid communication with the first drainage tube. The second drainage tube includes engagement flanges disposed within the receiving flanges of the first drainage tube.
