Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If fluid aerosol generating material is deposited on a surface during manufacturing, then aerosol generating substrate is formed, but the volume of fluid material becomes unstable leading to inconsistent deposition

Engineering Contradiction:
Improvedeposition consistencyVSAvoidvolume stability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-filling the storage means with a reservoir of fluid aerosol generating material before the deposition process begins. This ensures that the material is ready and available at a controlled volume before deposition starts, preventing volume instability during the actual deposition operation. The storage means is prepared in advance to maintain constant volume throughout the manufacturing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control means implements feedback by continuously monitoring the volume of fluid aerosol generating material in the storage means and automatically adjusting the supply rate to maintain a constant desired volume. This closed-loop control system detects volume changes and makes real-time corrections, ensuring stable deposition conditions throughout the manufacturing process.

Inventive Principle:
Principle #23Feedback

2Productivity

If fluid aerosol generating material is continuously supplied to maintain deposition, then production efficiency increases, but volume control becomes difficult leading to waste

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmaterial waste
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The control means uses feedback control to monitor the volume of fluid material in the storage means and automatically adjusts the supply rate from the supply means. When the volume approaches the desired level, the supply is automatically reduced or stopped, preventing overfilling and waste. This ensures continuous production while maintaining precise volume control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies self-service by enabling the storage means to automatically regulate its own volume through the control means, which responds to volume changes by adjusting supply. The system serves itself by detecting its own state (volume level) and making appropriate adjustments without external intervention, optimizing both productivity and material utilization.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the storage means volume varies during deposition, then supply flexibility is maintained, but deposition precision deteriorates

Engineering Contradiction:
Improvesupply flexibilityVSAvoiddeposition precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system applies dynamics by making the supply rate adjustable and responsive to changing conditions. The control means can dynamically modify the supply rate to maintain constant volume despite variations in deposition rate or material consumption. This dynamic adjustment maintains both supply flexibility and deposition precision throughout the manufacturing process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control means changes the supply parameter (flow rate) in response to volume measurements to maintain the desired volume constant. By adjusting this critical parameter, the system ensures that deposition precision is maintained while allowing flexibility in the overall supply process. The parameter change approach enables precise control without sacrificing adaptability.

Inventive Principle:
Principle #35Parameter changes
