Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different carrier fluids and active ingredients are used, then the spraying device can handle various spraying tasks, but the spraying result becomes inconsistent due to varying properties and interactions
Solution Approach 1:
The patent adjusts parameters of the spray solution by adding additives that modify pH value, water hardness, and other chemical properties to ensure consistent spraying results across different carrier fluid and active ingredient combinations
Solution Approach 2:
Additives are introduced as intermediary substances that mediate between different carrier fluids and active ingredients, improving miscibility and preventing unwanted interactions while maintaining reliable spraying performance
2Device complexity
If manual dosing of additives is used, then the device complexity is low, but the dosing precision and automation level are insufficient
Solution Approach 1:
The control device automatically determines the required additive dosage based on measured properties of carrier fluid and active ingredients, and activates the metering device to dosing the additives without manual intervention, achieving full automation
Solution Approach 2:
The system measures actual properties of the spray solution components and uses this feedback information to automatically adjust additive dosing, creating a closed-loop control system that ensures precise dosing
3Ease of operation
If additive dosing is manually determined, then the system is simple to operate, but the dosing accuracy and optimization are compromised
Solution Approach 1:
The patent replaces manual mechanical dosing with an automated system that uses measuring devices to detect properties and a control device to calculate and regulate additive dosing, achieving high precision without manual intervention
