Split Flange Wall Lead-Through with Hinge Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall ducts with divided flanges are complex and difficult to install due to insufficient positioning and guidance of individual parts, leading to increased costs and assembly challenges, especially when replacing damaged or destroyed flanges in existing installations.
Innovation Solution
The design incorporates a hinge joint mechanism with half-flange parts featuring a hinge bolt and hinge strap at separation points, ensuring secure assembly and alignment, along with a ring-like seal for effective sealing and strain relief, allowing for easy replacement and integration with pre-assembled cables or lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a divided flange is used to enable retrofitting in existing installations, then adaptability is improved, but device complexity increases due to insufficient positioning and guidance of individual parts
Solution Approach 1:
The flange is divided into two half-flange parts that can be assembled separately and then connected to form a complete flange. This segmentation enables retrofitting in existing installations where a complete flange cannot be installed as a single piece, while the hinge joint ensures proper alignment and positioning during assembly.
Solution Approach 2:
The hinge joint acts as an intermediary mechanism between the two half-flange parts, providing both connection and alignment functions. This intermediary element ensures that the individual parts are properly positioned and guided relative to each other and to the wall, resolving the positioning problem while maintaining adaptability.
2Ease of operation
If individual parts are divided for easier installation, then ease of operation is improved, but difficulty of assembly increases due to insufficient positioning and guidance
Solution Approach 1:
The hinge joint provides a dynamic connection that allows the half-flange parts to be assembled in a sequential manner. The hinge allows for some movement during assembly to accommodate positioning tolerances, then locks into a fixed position once aligned, making the assembly process easier while ensuring proper positioning.
Solution Approach 2:
The hinge joint serves as an intermediary that guides the relative positioning of the two half-flange parts. By incorporating the hinge into one of the half-flange parts, it automatically provides the necessary alignment and guidance during assembly, reducing the complexity of the assembly process.
3Reliability
If different connecting means are used on each half-flange part, then reliability of connection is improved, but manufacturing precision requirements increase
Solution Approach 1:
The two half-flange parts have asymmetric designs with different connecting means (hinge bolt vs. hinge strap). This asymmetry provides reliable connection through complementary fitting, where the hinge bolt of one part engages with the hinge strap of the other. The asymmetric design actually reduces manufacturing precision requirements by providing built-in alignment features that guide the parts into correct positioning during assembly.
