Solution Overview
Problem
Existing line ducts with elastomer bodies struggle to adapt to various line cross-sections and diameters, requiring complex production processes and multiple ducts, which can lead to deformation issues during molding and assembly.
Innovation Solution
A line duct design featuring a one-piece elastomer body with multiple shells arranged in a comb-like configuration, allowing for adjustable shell thickness and spacing to accommodate different line sizes, produced using injection molding or casting, with bridges connecting shells for enhanced stability and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If closed cutting lines are drawn in a solid elastomer body with a cutting tool, then layers can be separated, but the production process becomes complex and time-consuming
Solution Approach 1:
The elastomer body is divided into multiple layers during the molding process itself, rather than cutting them separately afterward. Each layer is formed as a distinct segment with defined thickness, allowing simultaneous production of multiple layers in one molding cycle, thus eliminating the need for subsequent cutting operations and reducing production complexity and time
Solution Approach 2:
The layer separation is prepared in advance during the molding process by forming preliminary separation structures (such as partial through-holes or separation channels) that enable easy separation of layers after molding, rather than requiring complex cutting operations after the elastomer body is fully formed
2Reliability
If the elastomer body is deformed with a tensioning device to seal against the line, then sealing effect is achieved, but the elastomer body may deform during molding and assembly
Solution Approach 1:
The elastomer body is divided into multiple thin layers instead of using a single thick elastomer body. This segmentation reduces the overall thickness of each layer, improving dimensional stability during molding and assembly while maintaining the sealing function through the cumulative effect of multiple layers being deformed by the tensioning device
Solution Approach 2:
The invention changes the thickness parameter of the elastomer body by dividing it into multiple thin layers. This parameter change reduces deformation during molding and assembly while maintaining sealing effectiveness through the combined deformation of multiple layers, thus resolving the contradiction between sealing reliability and dimensional stability
