Solution Overview

Problem

The addition of potassium to beverages often leads to an undesirable increase in pH, requiring the addition of acids like citric or malic acid to maintain a stable pH, which can affect microbial growth resistance and flavor profiles.

Innovation Solution

A blend of monopotassium phosphate and dipotassium phosphate or potassium citrate is used to fortify beverages, maintaining a stable pH without the need for additional acidic components, allowing for the creation of potassium-fortified beverages with desirable pH and taste profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If potassium citrate is added to fortify the beverage with potassium, then the potassium content increases, but the pH rises to an undesirable degree

Engineering Contradiction:
Improvepotassium contentVSAvoidpH level
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent combines multiple potassium sources (monopotassium phosphate, dipotassium phosphate, and potassium citrate) into a single blended fortification composition. This merging approach allows the different potassium compounds to work synergistically, with the phosphate components buffering the pH rise caused by the citrate, thereby maintaining stable pH while achieving desired potassium fortification levels.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent changes the chemical parameters of the potassium fortification by using a specific blend of potassium compounds with different chemical properties. Monopotassium phosphate and dipotassium phosphate have buffering capacities that counteract the pH increase from potassium citrate, effectively changing the overall pH trajectory to remain within desirable ranges while still providing adequate potassium.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If acid is added to counteract the pH rise from potassium fortification, then the pH is maintained at desirable levels, but the flavor profile and microbial growth resistance are affected

Engineering Contradiction:
ImprovepH levelVSAvoidflavor degradation and microbial growth resistance
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of pH rise into a beneficial buffering mechanism. The phosphate components in the potassium blend act as natural buffers that absorb excess base, transforming the pH instability problem into a self-regulating system that maintains pH without requiring additional acid additives, thereby preserving flavor and microbial resistance properties.

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

Solution Approach 2:

The blended potassium composition is designed to be self-regulating regarding pH. The combination of monopotassium phosphate, dipotassium phosphate, and potassium citrate creates an internal buffering system that automatically maintains pH within desirable ranges without external intervention, eliminating the need to add separate acidulents that would compromise flavor and microbial stability.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If additional acid is added to maintain pH, then the pH stability is improved, but the production efficiency and product quality are reduced

Engineering Contradiction:
ImprovepH stabilityVSAvoidproduction efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent merges the potassium fortification function with the pH buffering function into a single integrated composition. By combining monopotassium phosphate, dipotassium phosphate, and potassium citrate in specific ratios, the formulation simultaneously provides potassium enrichment and pH stabilization, eliminating the need for separate acid addition steps and thereby improving production efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The blended potassium composition performs multiple functions: it provides potassium fortification, buffers pH changes, and maintains beverage stability all in one addition. This multi-functionality eliminates the need for separate acidulents and simplifies the production process, improving both efficiency and product quality by reducing the number of processing steps.

Inventive Principle:
Principle #6Universality (Multi-functionality)
