Solution Overview
Problem
Existing fibre forming devices face challenges in accurately adjusting the temperature of the spinner wheel without modifying the gas flow, which affects fibre quality due to dependencies on various environmental and mechanical factors.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the burner is adjusted by adjusting the fuel/oxidizer arrival parameters to control temperature, then the temperature of the spinner wheel is modified, but the gas flow is also modified which affects fibre quality
Solution Approach 1:
The temperature control function is segmented from the gas flow control function. The invention introduces a separate air circulation device with independent control capabilities, allowing temperature adjustment without affecting the burner's gas flow parameters. This segmentation enables independent optimization of both temperature and fibre quality.
Solution Approach 2:
The air circulation device acts as an intermediary between the burner and the spinner wheel for temperature control. Instead of directly adjusting the burner's fuel/oxidizer parameters, the system uses the air circulation device to modify the thermal environment around the spinner wheel, thereby controlling temperature without interfering with the gas flow that directly affects fibre quality.
2Manufacturing precision
If the gas flow is modified to control fibre stretching, then the fibre quality is improved, but the temperature of the spinner wheel is also affected
Solution Approach 1:
The control functions are segmented into independent systems: gas flow control for fibre stretching and air circulation control for temperature management. This allows the gas flow to be optimized for fibre quality while the air circulation device independently maintains the required temperature of the spinner wheel.
Solution Approach 2:
The air circulation device serves multiple functions: it controls the temperature of the spinner wheel, manages smoke evacuation, and does not interfere with the gas flow used for fibre stretching. This multi-functionality allows temperature control without compromising fibre quality.
3Productivity
If the centrifuge operates at high rotation speed for fibre production, then productivity is improved, but the centrifuge is highly loaded by mechanical stresses leading to deformation and temperature variations
Solution Approach 1:
The air circulation device is equipped with independent control means that can respond to temperature variations caused by high-speed rotation. The system can detect temperature changes and adjust the air circulation accordingly, providing feedback control that maintains temperature stability despite the mechanical stresses and deformation associated with high productivity operation.
