Solution Overview

Problem

Current methods for diagnosing gastrointestinal disorders like IBS and IBD are limited by low sensitivity and inability to accurately determine the location of unhealthy gut states due to challenges in data collection and analysis, particularly in the gastrointestinal tract.

Innovation Solution

A method using a sensor device that ingests through the gastrointestinal tract to collect time series data on unhealthy gut biomarkers and pH, identifying transitions between tract parts to determine the occurrence and location of unhealthy gut states by analyzing changes in these data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If non-invasive methods (stool analysis) are used, then the method is simple and non-invasive, but sensitivity is low and location determination is impossible

Engineering Contradiction:
Improvenon-invasive methodVSAvoidsensitivity and location determination
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent uses an ingestible sensor capsule as an intermediary device that travels through the gastrointestinal tract to collect biomarker data directly at the measurement site. This mediator enables precise local measurements without requiring invasive procedures like colonoscopy, while achieving high sensitivity through direct detection in the gut environment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If invasive methods (colonoscopy) are used, then reliability is improved, but the procedure causes discomfort and is limited to certain tract portions

Engineering Contradiction:
Improvediagnosis reliabilityVSAvoiddiscomfort and accessibility limitations
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical invasive system of colonoscopy with a chemical/biological sensing system. Instead of using a large mechanical scope that causes discomfort and limits access, the invention uses small sensor capsules that can reach all portions of the GI tract through natural peristalsis, detecting biomarkers chemically without mechanical intrusion.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If data collection from the entire gastrointestinal tract is performed, then comprehensive coverage is achieved, but data analysis complexity increases

Engineering Contradiction:
Improvegastrointestinal tract coverageVSAvoiddata analysis complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent divides the gastrointestinal tract investigation into multiple independent sensor capsule units, each collecting data locally as it passes through. This segmentation allows comprehensive coverage of the entire tract while keeping each data collection unit simple and manageable, with data from each segment analyzed independently or integrated systematically.

Inventive Principle:
Principle #1Segmentation

AI summary

According to an aspect there is provided a method for identifying and localizing an unhealthy gut state in a gastrointestinal tract. The method comprises: receiving a first time series of data representing an unhealthy gut biomarker level and a second time series of data representing pH, wherein the time series are acquired by a sensor device while the device passes through the tract; identifying a first time point of a transition from a first to a second part of the tract based on value change of at least one of the first and second data; analyzing at least one of the time series, for identifying occurrence of the unhealthy gut state; and on if an occurrence of the unhealthy gut state is identified: determining a second time point of the occurrence of unhealthy gut state; and determining a location, along the gastrointestinal tract, of the unhealthy gut state based on the first and second time points.
