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

VSEngineering 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

Engineering Contradiction:
Improvemounting member structureVSAvoidheat transfer
Core Design Contradiction:
Device complexityVSLoss of energy

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improveheat transferVSAvoidinsulating structure
Core Design Contradiction:
Loss of energyVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveenergy consumptionVSAvoidassembly process
Core Design Contradiction:
Use of energy by stationary objectVSEase of manufacture

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.

Inventive Principle:
Principle #1Segmentation

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).
