Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electromechanical systems are used for precise dosing, then dosing precision is improved, but device size increases
Solution Approach 1:
The patent replaces complex electromechanical dosing systems with a gas-generating cell system that uses chemical reactions to produce gas pressure for dispensing. This substitution eliminates motors, sensors, and control electronics while achieving precise dosing through controlled gas generation rates, thereby reducing device size significantly.
Solution Approach 2:
The patent achieves precise dosing by controlling parameters of the gas-generating cell including the rate of gas generation, cell volume, and pressure characteristics. By adjusting these parameters, the system achieves accurate dosing without requiring large electromechanical components, thus resolving the contradiction between precision and size.
2Volume of moving object
If spring-driven systems or elastomer pumps are used, then device size is reduced, but dosing precision deteriorates
Solution Approach 1:
The patent replaces spring-driven and elastomer pump systems with a gas-generating cell system that uses controlled chemical reactions to produce gas pressure. This substitution maintains the compact size advantage while dramatically improving dosing precision through controllable gas generation rates and pressure characteristics, eliminating the precision limitations of passive mechanical systems.
Solution Approach 2:
The patent achieves precise dosing by controlling parameters of the gas-generating cell including the rate of gas generation, cell volume, and pressure characteristics. By adjusting these parameters, the system achieves accurate dosing without requiring large electromechanical components, thus resolving the contradiction between precision and size.
3Volume of moving object
If gas generating cell technology is used, then device size is reduced, but dosing reliability deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms including pressure sensors and control systems that monitor the gas generation process and adjust parameters in real-time. This feedback control ensures consistent and reliable dosing by compensating for variations in gas generation, thereby achieving high dosing reliability in a compact device.
Solution Approach 2:
The patent achieves precise dosing by controlling parameters of the gas-generating cell including the rate of gas generation, cell volume, and pressure characteristics. By adjusting these parameters, the system achieves accurate dosing without requiring large electromechanical components, thus resolving the contradiction between precision and size.
4Ease of operation
If electromechanical systems are used, then dosing controllability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex electromechanical control systems with a simplified gas-generating cell system that uses controlled chemical reactions. This substitution reduces device complexity by eliminating motors, sensors, and control electronics while maintaining dosing controllability through parameter control of gas generation.

AI summary
A conveyable medium, which may be gaseous, liquid, viscous, pasty, or pulverulent, is dispensed into an organism (human, animal, plant) or onto a technical system in a targeted, controlled, closed-loop controlled, and monitored manner by a displacement pumping principle using a gas produced by a gas generating cell. Conveyable media may be medicaments or active ingredients in a liquid, dissolved, or viscous form, as well as any type of supporting substance and liquid, and lubricants or protective agents (grease, oil) or reagents. The system includes the following parts: a) an operating, control, regulating, monitoring, and communication unit; b) a gas drive unit; c) an active ingredient reservoir; and d) a connection system.
