1Productivity

If manual intervention is used to monitor and adjust flue gas capture systems, then operational simplicity is maintained, but operational efficiency and reaction consistency deteriorate

Engineering Contradiction:

Improveoperational efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system automatically monitors flue gas parameters and adjusts fan speed and agitation without manual intervention. Sensors detect CO2 concentration, temperature, and humidity, while the processor autonomously controls the fan motor and agitation system to optimize capture efficiency and maintain reactant consistency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses sensors to continuously monitor flue gas parameters including CO2 concentration, temperature, and humidity. This feedback is processed to dynamically adjust fan speed and agitation intensity, creating a closed-loop control system that optimizes capture efficiency while maintaining reaction consistency.

Inventive Principle:

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The fan speed is dynamically adjusted based on real-time CO2 concentration measurements. The processor monitors sensor data and varies the fan motor speed to match actual capture needs, increasing speed when CO2 levels are high and reducing speed when levels are low, optimizing both efficiency and energy consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters including fan speed, agitation intensity, and reactant flow rate based on monitored flue gas conditions. These parameter adjustments optimize CO2 capture efficiency while minimizing energy consumption and reactant loss under varying operational conditions.

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system replaces manual monitoring and adjustment with automated electronic sensors and processors. Sensors detect reaction parameters including temperature, humidity, and CO2 concentration, while the processor automatically adjusts operational conditions, eliminating the need for manual intervention and ensuring consistent reaction quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If agitation is increased to prevent reactant loss and filter clogging, then reliability improves, but energy consumption increases

Engineering Contradiction:

Improvesystem reliabilityVSAvoidagitation energy

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The agitation system operates periodically rather than continuously, with the processor adjusting agitation intensity and duration based on reaction progress and reactant consistency measurements. This periodic action prevents filter clogging and maintains reactant quality while minimizing energy consumption compared to continuous agitation.

Inventive Principle:

Principle #19Periodic action
