Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the thickness of external insulation brick is reduced to increase heat dissipation capacity, then cooling efficiency is improved, but the structural strength and thermal shock resistance are compromised
Solution Approach 1:
The external insulation brick is segmented into multiple thin brick layers (e.g., 3-5 layers of 8mm bricks) with heat dissipation gaps between them, allowing heat to be dissipated through the gaps while maintaining structural integrity through the layered configuration
Solution Approach 2:
Heat dissipation gaps are strategically positioned at specific locations where heat accumulation is most problematic, creating localized heat dissipation channels without compromising the overall structural strength of the insulation system
2Productivity
If the cooling section length is increased to improve heat dissipation capacity, then cooling efficiency is improved, but manufacturing complexity and installation difficulty increase
Solution Approach 1:
The cooling section is divided into multiple modular units that can be manufactured separately and then assembled together, reducing manufacturing complexity while achieving the required total length and heat dissipation capacity
Solution Approach 2:
Instead of increasing length in one dimension, the solution adds heat dissipation gaps in the thickness direction of the insulation brick, providing additional heat dissipation pathways without extending the cooling section length
3Productivity
If localized rapid cooling is applied to increase cooling capacity, then cooling efficiency is improved, but thermal shock resistance requirements increase excessively
Solution Approach 1:
Multiple small heat dissipation gaps are distributed throughout the insulation brick, creating numerous localized heat dissipation points that collectively provide uniform cooling across the glass surface, avoiding concentrated thermal shock
Solution Approach 2:
The heat dissipation gaps provide slightly more cooling capacity than the minimum required, allowing for flexible adjustment and ensuring adequate cooling without creating excessive thermal gradients that would cause thermal shock
