Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional electric pump is used to circulate gas in a closed circuit, then the gas circulation function is reliable, but the device becomes heavy and consumes excessive electrical energy
Solution Approach 1:
The invention extracts and eliminates the traditional electric pump from the system. Instead of using a pump to circulate gas, the system uses the impeller within the conical chambers to generate pressure differences that drive gas circulation, thereby removing the heavy, energy-consuming pump component while maintaining circulation functionality
Solution Approach 2:
The invention replaces the mechanical pump system with a different mechanical mechanism involving impellers rotating within conical chambers. The impellers create pressure differences through their rotation, substituting the traditional pump's direct mechanical pushing action with a pressure-gradient-driven flow mechanism that is more energy-efficient
2Reliability
If a traditional electric pump is used to circulate gas in a closed circuit, then the gas circulation function is reliable, but the device becomes bulky and heavy
Solution Approach 1:
The invention extracts and eliminates the traditional electric pump from the system. Instead of using a pump to circulate gas, the system uses the impeller within the conical chambers to generate pressure differences that drive gas circulation, thereby removing the heavy, energy-consuming pump component while maintaining circulation functionality
Solution Approach 2:
The invention changes the geometric parameters of the chambers by using conical shapes with specific angle relationships (αA < αB). This geometric parameter optimization allows the system to achieve efficient gas circulation with a more compact and lighter structure compared to traditional pump-based systems
3Reliability
If traditional filtration systems with pumps are used, then gas filtration is effective, but the system complexity and device size increase
Solution Approach 1:
The invention merges the gas circulation function and the filtration function into a single integrated device. The impeller-driven pressure difference system simultaneously performs both gas circulation and drives gas through the filtration system, eliminating the need for separate pump and filter components and reducing overall system complexity
Solution Approach 2:
The circulation device with conical chambers and impellers serves multiple functions: it generates pressure differences for gas circulation, drives gas flow through the filtration system, and can be adapted for different filtration requirements. This multi-functional design reduces system complexity by consolidating multiple functions into a single device
