Spraying Device Bypass Line Pre-Dilution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray devices require pre-dilution of active ingredients in a separate storage container, leading to excess active substance usage and inefficient flowability, and lack the ability to quickly adapt the applied volume flow to changing requirements.
Innovation Solution
The active substance is continuously fed into a pressurized bypass line with a constant quantity ratio to the carrier liquid, which opens into the carrier liquid line leading to the spray nozzles, allowing for real-time pre-dilution and adjustment of the active substance concentration based on current requirements, using adjustable flow valves and a mixing chamber for homogeneous mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active ingredient is pre-diluted in a separate storage container, then the active substance is always available in the spray system, but excess active substance is wasted and environmental safety requirements are not met
Solution Approach 1:
The active ingredient is pre-diluted in a bypass line before the main carrier liquid flow, creating a concentrated stream that mixes with the main flow at a controlled point. This preliminary action ensures the active substance is ready for application without requiring large quantities to be stored in advance, thus maintaining reliability while reducing waste.
Solution Approach 2:
A bypass line acts as an intermediary pathway that carries a pre-diluted active ingredient solution separate from the main carrier liquid flow. This intermediary system allows controlled mixing at a specific point (T-mixer), enabling precise dosing and reducing excess active substance while ensuring continuous availability for spraying.
2Quantity of substance
If large amounts of active ingredient are pre-diluted in a separate container, then sufficient active substance is available for application, but the system cannot quickly adapt to changing requirements
Solution Approach 1:
The system uses adjustable flow valves in both the bypass line and main carrier liquid line, allowing dynamic adjustment of the mixing ratio in real-time. This enables the system to adapt quickly to changing application requirements while maintaining sufficient active substance quantity, resolving the contradiction between quantity and adaptability.
3Manufacturing precision
If active substance is fed into bypass line with constant quantity ratio, then precise concentration control is achieved, but device complexity increases
Solution Approach 1:
The system replaces complex electronic or computerized dosing systems with a simpler mechanical T-mixer configuration using flow valves and pressure-driven fluid dynamics. The constant quantity ratio is achieved through the inherent properties of the mixing chamber and valve control, providing precise concentration control without excessive device complexity.
