Solution Overview

Problem

Existing technologies fail to provide a glass composition that can continuously supply specific inorganic components to promote the growth of marine plants like algae and phytoplankton, while ensuring appropriate nutrient supply and controlling dissolution rates, which is crucial for sustainable aquaculture.

Innovation Solution

A glass composition containing trace metal oxides and inorganic components is developed, formulated as a water-soluble glass that dissolves well in water, allowing for controlled nutrient supply and promoting the growth of marine plants by continuously providing essential nutrients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a glass composition is designed to dissolve quickly in water to supply nutrients, then the nutrient supply rate is improved, but the duration of action is reduced

Engineering Contradiction:
Improvenutrient supply rateVSAvoidduration of nutrient supply
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent applies parameter changes by carefully controlling the chemical composition ratios of glass components (SiO2: 1-50 wt%, B2O3: 10-40 wt%, P2O5: 5-20 wt%, Na2O: 1-10 wt%, K2O: 1-10 wt%, CaO: 1-10 wt%, MgO: 1-10 wt%) to achieve optimal dissolution rate. This compositional parameter optimization enables the glass to dissolve at a controlled rate that provides nutrients continuously over an extended period while maintaining high productivity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining multiple glass-forming and glass-modifying oxides in specific proportions. The composite glass composition includes network formers (SiO2, B2O3, P2O5) and network modifiers (Na2O, K2O, CaO, MgO) that work together to create a material with tailored dissolution properties, resolving the contradiction between rapid nutrient release and sustained supply duration.

Principle #40Composite materials

2Ease of operation

If the glass composition is made highly water-soluble to supply nutrients effectively, then the ease of operation is improved, but the stability of the object's composition is reduced

Engineering Contradiction:
Improvewater solubilityVSAvoidcompositional stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by optimizing the ratio between glass-forming oxides (which provide stability) and glass-modifying oxides (which enhance water solubility). Specifically, the balanced composition with SiO2 (1-50 wt%) providing structural stability alongside controlled amounts of Na2O (1-10 wt%), K2O (1-10 wt%), CaO (1-10 wt%), and MgO (1-10 wt%) achieves both high water solubility for effective nutrient supply and compositional stability for controlled dissolution.
