Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uniform supplying pipes are used for all troughs, then the structure is simple and manufacturing cost is low, but the heating liquid supply amount cannot be differentiated among troughs leading to inefficient heat exchange
Solution Approach 1:
The patent applies local quality by making each supplying pipe have different flow path cross-sectional areas according to the specific heat exchange requirements of each trough. Outermost troughs receive less heating liquid through smaller cross-sectional area pipes, while intermediate troughs receive more through larger cross-sectional area pipes, optimizing heat exchange efficiency for each location.
2Productivity
If valves are installed to control heating liquid flow to each trough, then differentiated supply amounts can be achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent changes the physical parameter of the supplying pipes by varying their flow path cross-sectional areas. This passive geometric parameter change automatically controls the heating liquid flow distribution to each trough, eliminating the need for active valve control systems while achieving differentiated supply amounts optimized for each trough's heat exchange requirements.

Function Achieved in This Case
This configuration allows for efficient vaporization of liquefied gases by ensuring appropriate heating liquid distribution, eliminating the need for valves and reducing material and resistance costs, while maintaining consistent heat exchange rates among heat transfer tubes.
Implementation Method 1
a first supplying pipe connecting the manifold with the first trough for supplying the heating liquid from the manifold to the first trough; and a second supplying pipe connecting the manifold with the second trough for supplying the heating liquid from the manifold with the second trough, the second supplying pipe having a smaller flow path cross-sectional area than the first supplying pipe
Implementation Method 2
While the heating liquid is flowing down along the outer surface of each of the heat transfer tubes, the liquefied gas does heat exchange with the heating liquid with flowing upward in the heat transfer tubes. Owing to the heat exchange, the heating liquid has a decreased temperature, and the liquefied gas having an increased temperature vaporizes.
Implementation Method 3
the heating liquid is supplied to the plurality of troughs through the manifold and the plurality of supplying pipes. The heating liquid overflows from the troughs and is supplied to the plurality of heat transfer tubes of the heat transfer panels adjacent to each of the troughs. While the heating liquid is flowing down along the outer surface of each of the heat transfer tubes, the liquefied gas does heat exchange with the heating liquid with flowing upward in the heat transfer tubes.
