Solution Overview

Problem

Current treatments for kidney disorders like nephrolithiasis, particularly hypocitraturia, face challenges due to patient compliance issues with potassium citrate therapy and the lack of effective dietary measures to increase urinary citrate levels without high potassium intake, which is risky for individuals with chronic kidney disease.

Innovation Solution

A dietary supplement comprising alkali salts such as sodium bicarbonate, potassium citrate, and magnesium citrate, optionally with a sugar alcohol, formulated as a low or ultra-low potassium beverage, tablet, or powdered mixture, designed to increase urinary citrate levels and manage kidney stone formation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If potassium citrate is used as first line therapy for hypocitraturia, then urinary citrate levels are increased, but patient compliance deteriorates due to gastrointestinal disturbances and medication expense

Engineering Contradiction:
Improveurinary citrate levelsVSAvoidpatient compliance
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent changes the chemical parameters of the therapy by using alternative alkali salts (sodium bicarbonate, magnesium citrate) instead of potassium citrate, thereby maintaining the citrate-raising effect while avoiding the gastrointestinal side effects that reduce compliance

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs non-prescription dietary supplements rather than expensive prescription medications, making the therapy more accessible and sustainable for long-term use, thereby improving patient compliance

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Quantity of substance

If dietary modification is used to increase urinary citrate, then medication expense is reduced, but the dietary measures become arduous and difficult to maintain

Engineering Contradiction:
Improveurinary citrate levelsVSAvoiddietary adherence
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent uses inexpensive dietary supplement products that are easy to consume (beverages, tablets, powdered mixtures) rather than requiring complex dietary changes, making the therapy affordable and simple to adhere to long-term

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent creates a multi-functional product that serves both as a dietary supplement and a citrate-raising therapy, combining the benefits of dietary modification with the efficacy of medication in a single easy-to-use format

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

3Object-affected harmful factors

If low potassium diet is implemented for chronic kidney disease patients, then hyperkalemia risk is reduced, but urinary citrate increase for kidney stone prevention is limited

Engineering Contradiction:
Improvehyperkalemia riskVSAvoidurinary citrate levels
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent changes the ionic composition parameters by using sodium and magnesium-based citrate sources instead of potassium-based sources, thereby maintaining citrate delivery while reducing potassium load for chronic kidney disease patients

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments the alkali metal components by using a combination of sodium bicarbonate and magnesium citrate rather than relying on a single potassium source, allowing independent optimization of citrate delivery and potassium restriction

Inventive Principle:
Principle #1Segmentation
