Liquid Fertilizer Concentrate Siphon with Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fertilizers either burn lawns in hot weather or require rain to be effective, and dry fertilizers are inefficient in absorption.
Innovation Solution
A liquid fertilizer concentrate system with a container, siphon, and flow control valve that allows for controlled application and absorption, comprising a mixture of nitrogen, phosphorous, sulfur, potassium, iron sources, and water, enabling application in hot weather and efficient soil absorption without rain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid fertilizer is applied in hot weather, then fertilizer effectiveness is improved, but lawn burning occurs
Solution Approach 1:
The patent changes the concentration parameter of the fertilizer solution based on ambient temperature. The flow control valve adjusts the ratio of concentrate to water mixing, delivering lower concentrations in hot weather and higher concentrations in cooler weather, thereby maintaining effectiveness while preventing lawn burn
Solution Approach 2:
The system dynamically adjusts the fertilizer application rate in real-time based on temperature conditions. The flow control valve responds to temperature changes by modifying the flow rate, making the application system adaptive rather than static
2Ease of operation
If dry fertilizer is used, then storage and shipping are easier, but absorption efficiency is reduced
Solution Approach 1:
The patent employs a hydraulic system using a siphon to deliver liquid fertilizer concentrate without mechanical pumps. The siphon uses pressure differential and gravity to move the liquid, enabling easy storage and shipping of liquid fertilizer while maintaining high absorption efficiency through direct soil application
3Ease of operation
If dry fertilizer is applied, then application is simpler, but effectiveness without rain is reduced
Solution Approach 1:
The patent replaces the natural reliance on rain for fertilizer activation with a controlled hydraulic delivery system. The siphon-based liquid application system actively delivers fertilizer directly to the soil regardless of rainfall conditions, substituting passive dry fertilizer application with active liquid delivery
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe application in hot weather, efficient fertilizer absorption, cost savings, even distribution, convenience, and lower shipping costs compared to dry fertilizers.
Implementation Method 1
A siphon tube includes a siphon tube first portion in fluid communication with the liquid fertilizer concentrate and a siphon tube second portion fluidly coupled to the first inlet of the siphon

AI summary
A fertilizer application system for a liquid fertilizer concentrate includes a container containing a first fluid. A siphon is disposed on the container and includes two inlets and an outlet. A flow control valve is configured to selectively control an amount of first fluid flowing through the siphon based on ambient temperature of an environment outside the container. A siphon tube includes a siphon tube first portion in fluid communication with the first fluid, and a siphon tube second portion fluidly coupled to an inlet of the siphon. The first fluid includes a liquid fertilizer concentrate comprising a nitrogen containing source, a phosphorous containing source, a sulfur containing source, a potassium containing source, an iron containing source, and water.
