Solution Overview

Problem

Rehydration products, such as sports drinks, often have a salty taste due to the presence of electrolytes like sodium chloride and sodium citrate, which can deter consumers from consuming sufficient amounts, leading to inadequate rehydration.

Innovation Solution

An electrolyte blend comprising sodium lactate and potassium chloride is used to create beverages with a low salty taste, providing the necessary electrolytes for rehydration without the salty flavor, achieved by leveraging the larger molecular size of sodium lactate, which takes longer to register on taste buds, and the use of potassium chloride, which contributes less saltiness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional electrolytes (sodium chloride, sodium citrate) are used in rehydration beverages, then electrolyte content is sufficient for rehydration, but the beverage develops a salty taste that deters consumers

Engineering Contradiction:
Improveelectrolyte contentVSAvoidsalty taste
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the electrolyte blend by using sodium lactate instead of traditional sodium chloride and sodium citrate. This parameter change maintains the necessary electrolyte content while fundamentally altering the taste profile, reducing saltiness through the different chemical properties of lactate compared to chloride and citrate ions.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite electrolyte system combining sodium lactate with potassium chloride and other electrolytes in specific ratios. This composite approach allows the formulation of a beverage that provides comprehensive electrolyte replacement while the specific combination and ratios are optimized to minimize salty taste, achieving both rehydration effectiveness and palatability.

Inventive Principle:
Principle #40Composite materials

2Reliability

If electrolyte concentration is increased to ensure adequate rehydration, then rehydration effectiveness improves, but the salty taste becomes more pronounced

Engineering Contradiction:
Improverehydration effectivenessVSAvoidsalty taste intensity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes the different taste thresholds and perception characteristics of different electrolyte compounds. By changing from sodium chloride to sodium lactate, the system can achieve higher electrolyte concentrations without a proportional increase in perceived saltiness, as lactate has different taste properties that mask saltiness more effectively than chloride at equivalent concentrations.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If conventional electrolyte formulations are used, then rehydration needs are met, but consumer consumption is limited due to unpleasant taste

Engineering Contradiction:
Improveelectrolyte provisionVSAvoidconsumer consumption
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent fundamentally changes the taste parameter of the beverage by substituting traditional salty electrolytes with sodium lactate-based formulation. This makes the beverage more palatable and appealing to consumers, increasing the likelihood of adequate consumption to meet rehydration needs without the barrier of unpleasant salty taste.

Inventive Principle:
Principle #35Parameter changes
