Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing winding process for interlinked hollow fibers onto a core for mass and/or heat exchange devices is complex and requires a cumbersome adaptation to a drive, making it difficult to achieve quick and residue-free insertion into the exchange device.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a winding core is designed for direct insertion into the exchange device, then the insertion process is simplified and becomes residue-free, but the adaptation to a drive becomes more complex requiring additional coupling elements
Solution Approach 1:
The coupling element is divided into two distinct connection areas: a first connection area with a spreading element for connecting to the winding core, and a second connection area for connecting to the drive. This segmentation allows the coupling element to mediate between the simplified winding core design and the drive requirements, resolving the contradiction between easy insertion and drive adaptability.
Solution Approach 2:
The coupling element acts as an intermediary component between the winding core and the drive. It provides the necessary mechanical interface without modifying the winding core itself, enabling the winding core to maintain its simple insertion design while still achieving rotationally fixed connection to the drive through the coupling element.
2Ease of operation
If a spreading mechanism is used to connect the coupling element to the winding core, then axial movement is avoided and connection is achieved without residue, but the connection mechanism becomes more complex
Solution Approach 1:
The spreading element changes its radial dimension (parameter) when subjected to axial force. This parameter change allows the coupling element to expand radially and create a rotationally fixed connection with the winding core without requiring axial movement or leaving residues, achieving easy operation through a controlled parameter transformation.
3Productivity
If motorized winding is implemented, then winding efficiency and precision are improved, but the requirement for a coupling element increases device complexity
Solution Approach 1:
The coupling element serves multiple functions: it provides rotationally fixed connection to the drive, transmits rotational motion to the winding core, and enables easy assembly and disassembly. This multi-functionality allows motorized winding to be implemented without proportionally increasing device complexity, as a single coupling element accomplishes multiple requirements.
