Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices for extruding free-flowing food masses with filling flow dividers and nozzles are complex and time-consuming to assemble and clean, with many screw connections and parts contributing to high costs and inefficiencies.
Innovation Solution
A device with a movably mounted filling flow divider using a bearing device, such as a linear guide or modular nozzle block, simplifies assembly and cleaning by eliminating the need for multiple screw connections and allowing direct communication between outlets and inlets, reducing assembly and cleaning time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple screw connections and individual parts are used to connect filling flow divider and nozzle arrangement, then the device can be assembled and disassembled, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The filling flow divider and nozzle arrangement are merged into a single integrated unit that moves as one component. The bearing device supports both elements together, eliminating the need for separate screw connections between them. This integration directly reduces assembly complexity and time while maintaining the functional separation of the two components.
Solution Approach 2:
The filling flow divider is made movable relative to the nozzle arrangement through the bearing device, allowing dynamic positioning during assembly and operation. This movability enables simpler assembly procedures compared to fixed rigid connections, as the components can be easily positioned and adjusted without requiring multiple fastening operations.
2Ease of operation
If multiple screw connections are used in the device, then the structure is stable, but cleaning becomes expensive and difficult
Solution Approach 1:
By integrating the filling flow divider and nozzle arrangement into a single movable unit supported by the bearing device, the number of separate screw connections is dramatically reduced. This integration maintains structural stability while eliminating numerous cleaning-accessible fastening points, making the device easier and less expensive to clean.
3Loss of time
If a bearing device is used to mount the filling flow divider movably, then assembly is simplified and time is reduced, but the device structure becomes more complex
Solution Approach 1:
The bearing device introduces controlled movability to the connection between the filling flow divider and nozzle arrangement. This dynamic mounting mechanism, while structurally more complex than rigid fixed connections, significantly simplifies the assembly process by eliminating multiple screw connections and reducing assembly time, as the components can be easily positioned and adjusted.
