Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional melt spinning apparatuses face challenges in effectively suppressing heat transfer to plate-like members below the heating chamber, which can adversely affect adjacent devices and increase energy consumption.
Innovation Solution
A spinning equipment design that incorporates an insulating structure with a mounting member composed of multiple components, including first and second mounting members positioned horizontally apart, to lengthen the heat transfer path and increase thermal resistance, thereby reducing heat transfer to the plate-like member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-component mounting member is used to attach the plate-like member to the heating chamber, then the device complexity is reduced, but the heat transfer to the plate-like member increases
Solution Approach 1:
The mounting member is divided into multiple components (first mounting member, second mounting member, and connecting member) instead of using a single component. This segmentation increases the heat transfer path length and thermal resistance, thereby reducing heat transfer to the plate-like member while still achieving the attachment function.
Solution Approach 2:
The connecting member acts as an intermediary element between the first and second mounting members. It extends the heat transfer path and introduces additional thermal resistance, effectively mediating the heat transfer from the heating chamber to the plate-like member and reducing energy loss.
2Loss of energy
If the insulating material thickness is increased to suppress heat transfer, then the heat transfer is reduced, but the device complexity and space requirements increase
Solution Approach 1:
The insulation strategy is segmented into two parts: insulating material for general thermal isolation and a multi-component mounting member for targeted heat transfer path extension. This segmentation allows effective heat suppression without uniformly increasing insulating material thickness throughout the entire structure.
Solution Approach 2:
Instead of solely increasing insulation thickness in the vertical dimension, the solution extends the heat transfer path horizontally through the connecting member that connects the first and second mounting members. This dimensional approach to heat path extension provides effective thermal resistance without increasing vertical space requirements.
3Use of energy by stationary object
If the plate-like member temperature is reduced through better insulation, then energy saving is achieved, but the manufacturing complexity increases
Solution Approach 1:
The mounting member is segmented into standardized components (first mounting member, second mounting member, connecting member) that can be manufactured independently and assembled together. This segmentation allows for simpler individual component manufacturing while achieving the complex function of extended heat transfer path through modular assembly.

AI summary
To provide a spinning equipment capable of suitably suppressing heat transfer to a plate-like member disposed below a heating chamber. The spinning equipment comprises a heating chamber (6) to which a spinning pack (7) having a spinneret (8) is attached, a plate-like member (23) fixed to the heating chamber (6), and an insulating structure (20) for suppressing heat transfer to the plate-like member (23). The insulating structure (20) includes insulating materials (21, 22) provided between the heating chamber (6) and the plate-like member (23), and a mounting member (40) for attaching the plate-like member (23) to the heating chamber (6). The mounting member (40) has a first bolt (42) fixed to the heating chamber (6), a second bolt (43) that fixes the plate-like member (23) at a position different from the first bolt (42) in a horizontal direction, and a plate (41) disposed inside the insulating materials (21, 22) and connecting the first bolt (42) and the second bolt (43).
