Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If compensation mechanisms are implemented to ensure accurate dosing, then dosing precision is improved, but device complexity increases
Solution Approach 1:
The system measures the actual concentration of constituents in the inhalation media and compares it against target values. Based on this feedback, the control circuit calculates compensation values and adjusts the dose accordingly. This closed-loop feedback mechanism ensures dosing precision while keeping the control logic manageable through systematic comparison and adjustment procedures.
Solution Approach 2:
The system dynamically adjusts dosing parameters based on measured constituent concentrations. When concentrations deviate from target values, the control circuit modifies the dose parameters (such as actuation duration or intensity) to compensate for the deviations. This parameter adjustment approach enables precise dosing control without requiring complex hardware modifications.
2Measurement precision
If compensation values are calculated and applied to meet target doses, then dose accuracy is improved, but control system complexity increases
Solution Approach 1:
The system pre-establishes target concentration values and compensation procedures before actual dosing occurs. The control circuit is programmed with predetermined target values for constituents and automated procedures for calculating and applying compensation. This preliminary configuration simplifies the real-time control process while ensuring accurate dose delivery.
Solution Approach 2:
The control system automatically measures constituent concentrations, calculates compensation values, and adjusts doses without external intervention. The system serves itself by using its own measurements to drive its control actions, eliminating the need for complex external monitoring and control systems while maintaining high dose accuracy.
