Solution Overview

Problem

Current treatments for constipation do not effectively address the underlying mechanism of the condition, which is believed to be an infection of the gut flora by specific bacterial agents producing bioactive substances, leading to incomplete or variable responses in patients.

Innovation Solution

A composition comprising anti-clostridial agents such as vancomycin, vancomycin derivatives, aminoglycosides, nitroimidazoles, and opioid blocking agents, administered orally or via enema/suppository, to target and suppress the infective agents causing constipation, combined with prokinetic agents to enhance gut motility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional laxatives and dietary fiber are used to treat constipation, then bowel movement frequency may increase temporarily, but the underlying infective mechanism remains untreated leading to variable and incomplete responses

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtreatment regimen complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple anti-clostridial agents (vancomycin, metronidazole, rifaximin) with opioid blocking agents (naloxone, methyl naltrexone) and prokinetic agents into a single comprehensive treatment regimen. This merging of multiple therapeutic mechanisms addresses both the infective cause (Clostridium difficile overgrowth) and the functional consequence (opioid-mediated motility inhibition), thereby improving treatment reliability while managing complexity through coordinated action

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The treatment protocol functions as a composite therapeutic approach, integrating antibiotics with different mechanisms of action (cell wall synthesis inhibition, DNA damage, protein synthesis inhibition) alongside opioid antagonists and prokinetic agents. This composite strategy targets multiple pathogenic mechanisms simultaneously, ensuring more reliable outcomes compared to single-agent therapies

Inventive Principle:
Principle #40Composite materials

2Reliability

If multiple anti-clostridial agents are combined with opioid blocking agents, then treatment effectiveness improves by addressing both infection and motility, but the treatment regimen becomes more complex

Engineering Contradiction:
Improvetreatment response consistencyVSAvoidadministration simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The complex treatment regimen is segmented into distinct functional components: anti-clostridial agents (vancomycin, metronidazole, rifaximin) targeting the infective mechanism, opioid blocking agents (naloxone, methyl naltrexone) addressing motility inhibition, and prokinetic agents enhancing bowel movement. This segmentation allows each component to be optimized for its specific function while collectively improving treatment response consistency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces opioid blocking agents as intermediary substances that mediate between the infective mechanism and the functional outcome. These agents block opioid receptors in the gut, preventing opioid-mediated motility inhibition caused by Clostridium difficile toxins, thereby bridging the gap between eliminating infection and restoring normal bowel function

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If fiber intake is increased to treat constipation, then bowel bulk increases, but this does not address the root cause and may worsen symptoms in infected bowel flora

Engineering Contradiction:
Improvebowel content volumeVSAvoidbacterial infection progression
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of Clostridium difficile overgrowth into a diagnostic and therapeutic opportunity. By identifying constipation as potentially caused by C. diff infection rather than simple dietary insufficiency, the treatment uses anti-clostridial agents to eliminate the pathogen, thereby converting a harmful infectious process into a treatable condition with specific targeted therapy

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

Solution Approach 2:

Instead of following the conventional approach of increasing fiber to treat constipation, the patent inverts the logic by first eliminating the infective cause (Clostridium difficile) that may be preventing normal bowel function. This inversion reveals that treating the underlying infection rather than the symptomatic fiber deficiency leads to more effective and sustainable resolution of constipation

Inventive Principle:
Principle #13The other way round (Inversion)
