Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the heat capacity of the heating unit is increased to suppress temperature variation due to disturbance factors, then the temperature stability is improved, but the size of the heater is considerably increased
Solution Approach 1:
The heating unit is divided into two distinct heating members: a first heating member with high volumetric specific heat (e.g., copper alloy) and a second heating member with low volumetric specific heat (e.g., aluminum alloy). This segmentation allows each component to serve a specialized function - the first member provides thermal stability while the second member enables rapid heating - without requiring the entire heating unit to be oversized.
Solution Approach 2:
Different regions of the heating unit are assigned different material properties tailored to their specific functions. The first heating member uses high volumetric specific heat material for thermal stability, while the second heating member uses low volumetric specific heat material for rapid temperature response. This local differentiation optimizes overall performance without increasing total size.

Function Achieved in This Case
This configuration effectively suppresses temperature decreases and rapidly increases the yarn running space temperature, maintaining stability and efficiency while minimizing production costs.
Implementation Method 1
the first material forming the first heating member is a material having the volumetric specific heat which is relatively high, the decrease in temperature of the heating unit due to disturbance factors is suppressed to some degree
Implementation Method 2
the volumetric specific heat of the second material is low, with the result that the temperature of the second heating member made of the second material is increased more rapidly than that of the first heating member
