Solution Overview

Problem

There is a need for a stable and less bitter calcium preparation that is transparent and stable at high concentrations, particularly in a wide pH range higher than slightly acidic, as existing techniques fail to provide such a solution effectively.

Innovation Solution

An aqueous preparation of calcium comprising water, calcium, a compound of Formula I (citric acid structure), and a compound of Formula II (phosphoric acid structure), where 98% or more of the calcium is in a non-ionic form, forming a complex that binds with these compounds and forms colloidal particles, maintaining transparency and stability at pH values ranging from 4 to 13.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If calcium is dissolved in water to create a calcium solution, then calcium availability is improved, but the solution becomes unstable and forms precipitates over time

Engineering Contradiction:
Improvestability of calcium solutionVSAvoidtransparency and homogeneity of calcium solution
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent introduces citric acid and phosphoric acid as intermediary substances that mediate between calcium ions and water. These intermediaries form stable complexes with calcium, preventing direct precipitation and maintaining solution stability and transparency over time.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite calcium preparation system containing calcium ions, citric acid, phosphoric acid, and water. This composite formulation leverages the synergistic effects of multiple components to achieve enhanced stability and prevent precipitation that cannot be achieved with simple calcium solutions.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If calcium concentration is increased to provide sufficient calcium intake, then nutritional effectiveness is improved, but bitterness increases and oral ingestion becomes difficult

Engineering Contradiction:
Improvecalcium concentrationVSAvoidbitterness of calcium solution
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the calcium solution by introducing citric acid and phosphoric acid. This alters the taste profile and reduces bitterness, enabling higher calcium concentrations to be orally ingested without the unpleasant bitter taste that would otherwise prevent continuous consumption.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If pH is adjusted to improve calcium solubility, then dissolution rate is improved, but solution stability deteriorates at extreme pH values

Engineering Contradiction:
Improvedissolution rate of calciumVSAvoidstability of calcium solution at extreme pH
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent optimizes the pH parameter within a specific range (pH 4-13) and introduces citric acid and phosphoric acid that stabilize calcium solubility across this wide pH range. This allows efficient calcium dissolution while maintaining solution stability even at extreme pH values within the specified range.

Inventive Principle:
Principle #35Parameter changes
