Engineering Contradiction Analysis
1Device complexity
If a two-dimensional cavitation process is used, then the device structure is simpler, but the efficiency is lower and noise is higher
Solution Approach 1:
The patent transitions from a two-dimensional cavitation process to a three-dimensional cavitation process by introducing a constricting form with cavitation steps that create cavitation bubbles in multiple spatial dimensions. This dimensional change increases the surface area for heat transfer and improves heating efficiency while maintaining device structure simplicity.
2Device complexity
If a two-dimensional cavitation process is used, then the device structure is simpler, but noise is higher
Solution Approach 1:
By implementing a three-dimensional cavitation process through constricting forms and cavitation steps, the patent distributes cavitation activity across multiple spatial dimensions. This reduces the concentration of cavitation events in a single plane, thereby lowering noise generation while keeping the device structure relatively simple.
Solution Approach 2:
The patent converts the harmful noise-generating cavitation process into a beneficial heating process by carefully controlling cavitation bubble formation and collapse in a three-dimensional space. The cavitation steps and constricting form guide the cavitation process to produce heat efficiently while minimizing noise through proper geometric design.

Solution Approach 1:
The patent converts the potentially destructive cavitation process into a beneficial heating process by using constricting forms and cavitation steps to control bubble formation. The three-dimensional cavitation process directs energy toward heating the liquid rather than creating destructive forces, transforming a harmful phenomenon into a useful one.
Solution Approach 2:
The patent changes the geometric parameters of the cavitation process by introducing constricting forms with specific dimensions and cavitation steps at predetermined locations. These parameter changes control the pressure and temperature conditions during cavitation, ensuring that the process generates heat without creating destructive forces that could damage the device or liquid.
4Use of energy by moving object
If energy utilization is improved, then heating efficiency increases, but device complexity increases
Solution Approach 1:
The patent improves energy utilization by changing the geometric parameters of the cavitation process through constricting forms and cavitation steps. These parameter changes optimize the pressure and temperature conditions for cavitation, ensuring that energy is efficiently converted into heat. The device complexity is kept manageable by using straightforward geometric modifications rather than complex control systems.
