Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ultrasonic waves are used to crush microbubbles to produce ultrafine bubbles, then ultrafine bubbles can be manufactured, but the device configuration becomes complicated and size increases
Solution Approach 1:
The patent replaces the ultrasonic wave system with a mechanical collision system. Two water streams are made to collide at high speed within a collision chamber, mechanically breaking down microbubbles into ultrafine bubbles without requiring ultrasonic generators or complex control systems. This mechanical approach simplifies the device configuration while achieving the same ultrafine bubble production goal.
Solution Approach 2:
The invention uses hydraulic principles by utilizing high-speed water streams to achieve bubble crushing. Water is supplied through nozzles at high velocity, and the kinetic energy of the colliding water streams provides the force needed to break down microbubbles. This hydraulic approach eliminates the need for electrical ultrasonic components, reducing device complexity and size.
2Manufacturing precision
If ultrasonic waves are applied from one side to microbubble-containing water, then ultrafine bubbles are manufactured, but manufacturing efficiency is relatively low and bubble diameters are non-uniform
Solution Approach 1:
The invention divides the single-sided ultrasonic treatment into a dual-stream collision system. Instead of treating water from one side, two separate water streams are generated and made to collide. This segmentation allows both streams to contribute to bubble breakdown simultaneously, improving manufacturing efficiency while the head-on collision provides uniform force distribution, resulting in more uniform bubble diameters.
Solution Approach 2:
The high-speed colliding water streams create intense mechanical vibration and turbulence at the collision point. This mechanical energy input is more uniform and efficient than single-sided ultrasonic waves, causing microbubbles to be broken down more consistently into uniform ultrafine bubbles while processing larger volumes of water per unit time.
3Manufacturing precision
If batch processing steps are used to collect and process small diameter bubbles, then ultrafine bubbles can be manufactured, but manufacturing is intermittent and efficiency is low
Solution Approach 1:
The invention transforms the batch processing approach into a continuous flow system. Water streams continuously collide in the collision chamber, and ultrafine bubbles are continuously generated and discharged. This eliminates the intermittent nature of batch processing, allowing continuous manufacturing of ultrafine bubbles with consistent quality, thereby significantly improving productivity.
