Innovation Solution
A method for manufacturing a pipe assembly by blow molding, where at least one functional element is positioned in a recess of a blow mold, and a tubular preform is inserted to form a through-opening between the channel and the functional element during the blow molding process, allowing for a form-fit and/or material-fit connection of the functional element to the base body, eliminating the need for subsequent opening of blind outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If functional elements are integrated directly into the pipe assembly during blow molding, then manufacturing efficiency is improved and subsequent opening steps are eliminated, but the complexity of the blow molding process increases
Solution Approach 1:
The functional elements are positioned in the blow mold cavities before the blow molding process begins. The preform is then molded directly around these pre-positioned functional elements, creating through-openings and integrating the elements into the pipe assembly in a single step. This preliminary positioning eliminates subsequent opening steps and manual assembly operations.
Solution Approach 2:
The invention combines multiple operations into a single blow molding process: creating the pipe assembly base body, forming through-openings, and integrating functional elements all occur simultaneously. The mold cavity design integrates the functional element positioning features directly into the blow mold structure, merging what would traditionally be separate manufacturing steps into one unified process.
2Reliability
If through-openings are created during blow molding for functional element integration, then media-tight connections are ensured, but the precision requirements for mold recess positioning increase
Solution Approach 1:
The functional elements are nested within recesses or cavities in the blow mold structure. The mold design includes precisely formed recesses that receive and position the functional elements during the blow molding process. The preform is molded around these nested functional elements, ensuring precise positioning and creating sealed through-openings that guarantee media-tight connections.
Solution Approach 2:
The blow molding process itself creates the through-openings and positions the functional elements without requiring separate operations. The material flow and pressure during blow molding automatically form the connections between the pipe assembly and functional elements, with the mold structure providing the necessary positioning features that ensure both precision and sealing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method enables the direct creation of openings for functional elements during blow molding, facilitating secure and easy attachment of outlets, branches, or connectors to the pipe assembly, reducing the need for separate opening steps and ensuring a media-tight connection.
Implementation Method 1
During the process, the preform conforms to the inner wall of the mold, which defines the outer contour of the pipe assembly
Implementation Method 2
into which a partial area of the preform is formed and broken open by blow molding
