Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If desorption gas is supplied to multiple CO2 adsorption devices in a distributed manner, then the number of CO2 supply fans can be reduced, but temperature variation occurs between devices due to different flow passage resistances
Solution Approach 1:
The patent introduces flow passage resistance adjusting members into individual flow dividing portions to create localized flow control. Each branch can have its flow resistance independently adjusted to compensate for differences in device characteristics, ensuring uniform temperature distribution across all CO2 adsorption devices while maintaining the distributed gas supply architecture.
Solution Approach 2:
The patent changes the flow passage resistance parameter in each branch by introducing adjustable resistance members. By modifying this physical parameter locally in each flow dividing portion, the system achieves uniform gas distribution and temperature control across multiple devices without requiring additional fans.
2Productivity
If flow passage resistance is not equalized across devices, then devices with smaller resistance receive excessive flow rates, but this causes temperature rise and material deterioration
Solution Approach 1:
The patent applies local flow control by placing adjustable resistance members in each flow dividing portion. This allows individual adjustment of gas flow to each CO2 adsorption device, preventing excessive flow rates that would cause temperature rise and material deterioration while maintaining adequate productivity.
Solution Approach 2:
The patent implements a control mechanism that monitors flow rates and temperature in each branch, and adjusts the flow passage resistance accordingly. This feedback control prevents excessive flow rates that would lead to material deterioration while maintaining optimal productivity.
3Temperature
If flow passage resistance is not equalized across devices, then devices with larger resistance receive insufficient flow rates, but this prevents reaching required desorption temperature
Solution Approach 1:
The patent introduces flow passage resistance adjusting members into individual flow dividing portions to create localized flow control. Each branch can have its flow resistance independently adjusted to ensure adequate gas flow reaches devices with higher resistance, enabling them to achieve the required desorption temperature.
Solution Approach 2:
The patent changes the flow passage resistance parameter in each branch to optimize gas distribution. By adjusting this parameter locally, devices with larger resistance receive sufficient flow rates to reach desorption temperature while maintaining overall system productivity.
4Temperature
If resistors are added to flow dividing portions, then flow rates can be equalized, but device complexity increases
Solution Approach 1:
The patent introduces flow passage resistance adjusting members into individual flow dividing portions to create localized flow control. Each branch can have its flow resistance independently adjusted to compensate for differences in device characteristics, ensuring uniform temperature distribution across all CO2 adsorption devices while maintaining the distributed gas supply architecture.
Solution Approach 2:
The patent changes the flow passage resistance parameter in each branch by introducing adjustable resistance members. By modifying this physical parameter locally in each flow dividing portion, the system achieves uniform gas distribution and temperature control across multiple devices without requiring additional fans.
