Solution Overview

Problem

Current bowel preparation methods for capsule endoscopy are inadequate in ensuring rapid and complete visualization of the gastrointestinal tract, often resulting in incomplete transit of the capsule endoscope due to slow transit times and battery exhaustion, necessitating improved solutions for cleansing and propulsive enhancement.

Innovation Solution

An oral sulfate solution comprising sodium sulfate, potassium sulfate, and magnesium sulfate, administered in specific concentrations, is used to purge and cleanse the gastrointestinal tract, acting as a transit speed enhancer to facilitate rapid capsule endoscope movement through the GI tract without phosphate salts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional bowel preparation methods are used, then the GI tract is cleansed, but transit time is too slow causing incomplete visualization

Engineering Contradiction:
Improvecompleteness of GI tract visualizationVSAvoidtransit time through GI tract
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the chemical composition parameters of the bowel preparation solution by using sulfate salts (magnesium sulfate, sodium sulfate, potassium sulfate) instead of traditional phosphate-based solutions. This parameter change in the preparation solution's ionic composition stimulates more rapid intestinal motility while maintaining effective cleansing, thereby reducing transit time and ensuring complete capsule endoscope passage through the GI tract.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If capsule endoscope battery capacity is increased, then transit duration is extended, but device size and complexity increase

Engineering Contradiction:
Improvebattery operation durationVSAvoidcapsule endoscope structure
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by optimizing the bowel preparation before capsule endoscopy to ensure rapid and complete transit through the GI tract. By using sulfate-based preparation solutions that stimulate faster intestinal motility, the capsule completes its journey more quickly, reducing the required battery duration and allowing for simpler, more compact capsule designs without compromising visualization completeness.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If phosphate-based bowel preparation is used, then cleansing is effective, but electrolyte disturbances occur

Engineering Contradiction:
Improvequality of bowel cleansingVSAvoidelectrolyte disturbances
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces long-standing phosphate-based bowel preparation solutions with sulfate-based alternatives (magnesium sulfate, sodium sulfate, potassium sulfate). These sulfate salts effectively stimulate intestinal motility and provide thorough cleansing similar to phosphate solutions but with a more favorable electrolyte profile that causes fewer disturbances, making them a superior disposable preparation option for capsule endoscopy.

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