Solution Overview

Problem

Current silicon supplements, particularly those derived from silica gels/sols, pulverized quartz, or silica from plant material, are not bioavailable due to low solubility and often come in caustic forms, posing dosing errors and safety risks, while existing bioavailable forms like quaternary ammonium compounds are not user-friendly.

Innovation Solution

Combining Group Ia silicon salts, such as sodium or potassium silicate, with C1 to C6 hydroxy carboxylic acids and a solubilizing agent like tetraalkylammonium hydroxide to create a bioavailable, pH-neutral, and easily controllable solid supplement, which can be derived from biogenic sources like rice or diatomaceous earth, enhancing bioavailability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If silica gels/sols, pulverised quartz or plant-derived silica are used as silicon supplements, then the supplement is stable and easy to manufacture, but the bioavailability is low due to low solubility

Engineering Contradiction:
ImprovestabilityVSAvoidbioavailability
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the chemical parameters of silicon supplements by using water-soluble silicon salts (sodium silicate, potassium silicate, calcium silicate) instead of traditional insoluble silica forms. This parameter change transforms the solubility characteristic, enabling high bioavailability while maintaining stability through the specific chemical composition and pH control (5.0-9.0) of the supplement formulation.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If quaternary ammonium compounds are used to stabilize soluble silicon solutions, then high levels of bio-available silicon are provided, but the solution becomes caustic causing dosing errors and safety accidents

Engineering Contradiction:
ImprovebioavailabilityVSAvoidcaustic nature
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and eliminates the harmful caustic components (quaternary ammonium compounds and excessive alkali) from the silicon supplement formulation. Instead, it uses water-soluble silicon salts buffered to a safe pH range (5.0-9.0), maintaining high bioavailability through the soluble silicon salt form while removing the safety hazards associated with caustic solutions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the potentially harmful caustic silicon solutions into beneficial safe formulations by controlling the pH to be neutral or slightly acidic/basic (5.0-9.0). The silicon salts that would normally be caustic are now presented in a buffered, safe form that maintains solubility and bioavailability while eliminating the harmful effects, turning a dangerous substance into a safe supplement.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of manufacture

If potassium silicate or sodium silicate is used as silicon source, then readily available materials are used, but the solution is caustic and not user friendly

Engineering Contradiction:
Improveavailability of materialsVSAvoiduser friendliness
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent changes the pH parameter of commercially available silicon salts (potassium silicate, sodium silicate) from their naturally caustic state to a safe, user-friendly range (pH 5.0-9.0). This is achieved through buffering with organic acids or carbonates, making the materials both easily manufacturable from available sources and safe for consumer use while maintaining high silicon bioavailability.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If silica from plant material is used, then natural source is provided, but the solubility is low resulting in poor bioavailability

Engineering Contradiction:
Improvenatural sourceVSAvoidsolubility
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent changes the chemical form parameter from insoluble plant-derived silica to water-soluble silicon salts (sodium silicate, potassium silicate, calcium silicate). This parameter transformation maintains the natural origin appeal while dramatically improving solubility and bioavailability, as the silicon salts dissolve readily in water to provide bioavailable silicon in the pH 5.0-9.0 range.

Inventive Principle:
Principle #35Parameter changes
