Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a conventional pipeline with uniform inner diameter is used, then the system structure is simple, but the gas flow resistance increases and conveying distance is limited
Solution Approach 1:
The pipeline inner diameter is made non-uniform, with different sections having different diameters. The diameter gradually changes from smaller at the material inlet to larger at the gas outlet, optimizing gas flow distribution in different sections to reduce overall resistance
Solution Approach 2:
The pipeline diameter is designed to dynamically adapt to the gas flow characteristics along the conveying path, with the diameter increasing as gas accumulates and pressure builds up, maintaining optimal flow conditions throughout the system
2Length of stationary object
If the power and fan system is enhanced to achieve long-distance conveying, then conveying distance increases, but energy consumption increases
Solution Approach 1:
The pipeline diameter parameter is changed along the flow direction, creating a gradient structure that reduces gas flow resistance. This allows the existing power system to achieve longer conveying distances without increasing energy input
3Length of stationary object
If a pipeline with gradually enlarged inner diameter is used, then gas flow resistance decreases and conveying distance extends, but the pipeline structure becomes more complex
Solution Approach 1:
The pipeline is divided into multiple sections with different diameter specifications. Each section is designed with a specific diameter range to optimize gas flow at different stages, and sections can be assembled in sequence to achieve the gradual enlargement effect
