Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid metallic pipes are used as conveying lines, then gas leakage is prevented and reliable operation is maintained, but installation complexity increases especially in hard-to-reach locations and aquatic environments
Solution Approach 1:
The conveying line is divided into modular sections with flexible parts and rigid parts that can be independently installed and connected. This segmentation allows the rigid sections with gas injecting devices to be installed in accessible locations while flexible sections navigate hard-to-reach areas, resolving the contradiction between reliable gas containment and installation complexity.
Solution Approach 2:
Flexible hoses or tubes are used as conveying lines instead of rigid metallic pipes in certain sections. These flexible components can be easily installed in hard-to-reach locations and aquatic environments while still maintaining gas containment through proper material selection and design, thereby reducing installation complexity without sacrificing reliability.
2Productivity
If gas injecting devices are installed in conveying lines, then material movement is improved and gas usage efficiency is increased, but gas leakage risks increase and installation precision requirements increase
Solution Approach 1:
The system incorporates pressure regulation mechanisms and check valves before the gas injecting devices to prevent backflow and overpressurization. This beforehand cushioning protects against gas leakage while maintaining the efficiency benefits of the injecting devices, resolving the contradiction between productivity improvement and gas containment reliability.
3Productivity
If gas injecting devices are installed in conveying lines, then material movement is improved, but installation precision requirements and device complexity increase
Solution Approach 1:
The gas injecting devices are designed as universal, modular units that can be installed in standardized locations along the conveying line. These multi-functional devices serve both material propulsion and pressure regulation functions, simplifying the installation process while maintaining material movement efficiency, thus resolving the contradiction between productivity and installation precision requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates pneumatic conveyance in challenging environments by providing flexible installation and reducing gas leakage, while maintaining reliable operation.
Implementation Method 1
Such injecting devices typically operate by means of a pressure difference. When a pressure in the conveying line is below a pressure of a gas supply head of the injecting device, the gas flows through the injecting device into the line.
Implementation Method 2
When a pressure in the conveying line is above a pressure of a gas supply head of the injecting device, a valve, such as a diaphragm, closes the gas flow from the injecting device.
Implementation Method 3
pneumatic conveyance generally involves a system composed of one or more pipes, valves, air pumps or compressors, tanks and pneumatic conveyors. the materials to be transported are loaded inside a pneumatic conveyor that is typically responsible for pushing the material from its interior into a conveying line by means of a gas stream.
