Lance Dispensing Device for Pasty Fertilizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fertilizer application devices, particularly for commercial plant cultivation, face inefficiencies with liquid fertilizers due to frequent dosing needs, dust formation from granules, and limited nutrient retention, while existing pasty fertilizer devices are not economical for large-scale use.
Innovation Solution
A dispensing device with a receptacle and lance-like dispensing mechanism, utilizing a pump to generate pressure for precise metered dispensing of pasty fertilizer through a lance tip, eliminating dust and ensuring long-term nutrient supply, featuring a compact and portable design with manual or electric operation and adjustable dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid fertilizer is used for nutrient supply, then easy dosing and application is achieved, but frequent applications are required which are labor-intensive
Solution Approach 1:
The patent changes the physical state parameter of the fertilizer from liquid to paste form. This parameter change allows the fertilizer to maintain ease of dosing while achieving long-term nutrient supply, thereby reducing application frequency and labor requirements
Solution Approach 2:
The paste fertilizer provides excessive nutrient supply duration compared to liquid fertilizer, ensuring that nutrients are available for an extended period without requiring frequent reapplication, thus improving productivity
2Duration of action of stationary object
If granule fertilizer is used for long-term supply, then nutrient retention is improved, but dust formation and application opening blockage occur
Solution Approach 1:
The patent changes the physical state parameter from granular solid to paste form. This transformation eliminates dust generation during handling and application while maintaining long-term nutrient supply capabilities, and the paste consistency prevents blockage of application openings
Solution Approach 2:
The paste fertilizer acts as a disposable material that is applied once and provides long-term nutrients without generating harmful byproducts like dust, eliminating the need for cleaning or maintenance of application equipment
3Measurement precision
If pasty fertilizer with pressure-sensitive container and valve opening is used, then precise dosing is achieved, but the device is not economical for large-scale use
Solution Approach 1:
The patent segments the fertilization system into a reusable dispensing device and replaceable paste fertilizer cartridges. This segmentation allows the precision dosing mechanism to be used repeatedly while only the consumable paste portion needs replacement, making the system economical for large-scale commercial use
Solution Approach 2:
The dispensing device is designed as a universal tool that can handle paste fertilizer with precise dosing capabilities, making it suitable for both small-scale precise applications and large-scale commercial operations, thereby improving scalability
