Solution Overview

Problem

Current treatments for hoarseness and inflammatory diseases of the mouth and throat, such as sore throats, often fail to provide satisfactory relief from pain and inflammatory symptoms, especially for organic causes, and existing remedies like hot milk with honey can exacerbate issues or offer only short-term relief.

Innovation Solution

A pharmaceutical composition combining antiviral polysaccharides, polyhexanide as a surface disinfectant, and hyaluronic acid, which forms a protective film on the mucous membrane to prevent pathogen penetration, reduce dryness, and provide long-lasting pain relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If home remedies like hot milk with honey are used, then temporary soothing effect is achieved, but mucus formation increases and healing process is hindered

Engineering Contradiction:
Improvesoothing effectVSAvoidmucus formation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of honey (increasing mucus formation) into a beneficial formulation by combining it with specific antiviral polysaccharides and polyhexanide. The composition maintains the soothing property while the polysaccharides counteract the mucus-forming effect, transforming a harmful home remedy into an effective pharmaceutical composition.

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

Solution Approach 2:

The invention creates a composite pharmaceutical composition combining multiple active ingredients: antiviral polysaccharides (from plants or fungi), polyhexanide (surface disinfectant), and optionally local anesthetics or anti-inflammatory agents. This composite formulation achieves both soothing and antimicrobial effects simultaneously, resolving the contradiction between temporary relief and harmful mucus formation.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If commercially available lozenges are used, then short-term relief is provided, but effect wears off extremely quickly

Engineering Contradiction:
Improveshort-term reliefVSAvoidduration of effect
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The patent ensures continuous therapeutic action by formulating a composition with slow-release properties. The polysaccharide matrix and polyhexanide combination provides sustained release of antiviral and anti-inflammatory active ingredients, maintaining effective concentrations in the throat area for extended periods rather than the brief duration of conventional lozenges.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The invention changes the release parameters of the active ingredients by using polysaccharide-based matrices that control diffusion and degradation rates. This parameter modification extends the duration of action from minutes to hours, allowing the composition to maintain therapeutic effectiveness throughout the day.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If conventional treatments are used for inflammatory diseases, then some symptom relief is achieved, but sufficient relief from pain and inflammatory symptoms is not provided

Engineering Contradiction:
Improvesymptom reliefVSAvoidsufficiency of relief
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges multiple therapeutic mechanisms into a single composition: antiviral polysaccharides provide direct viral inhibition and immunomodulation, polyhexanide provides broad-spectrum antimicrobial activity, and optional local anesthetics/anti-inflammatories provide immediate symptom relief. This combination achieves reliable and sufficient relief from pain and inflammatory symptoms that conventional single-mechanism treatments cannot provide.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The composition is designed for local application in the throat and mouth areas, with formulations specifically tailored to provide high concentrations of active ingredients at the site of infection. The local anesthetics and anti-inflammatories are positioned to act directly on inflamed tissues, providing reliable pain and inflammation relief in the specific affected areas.

Inventive Principle:
Principle #3Local quality

4Reliability

If antiviral polysaccharides and polyhexanide are combined, then synergistic effect is achieved, but formulation complexity increases

Engineering Contradiction:
Improvesynergistic effectVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses polysaccharides as intermediary substances that facilitate the interaction between polyhexanide and the target pathogens. The polysaccharide matrix enhances the antimicrobial activity of polyhexanide through synergistic mechanisms, while the combination is formulated in a way that maintains stability and compatibility, managing the formulation complexity through careful selection of excipients and processing methods.

Inventive Principle:
Principle #24Intermediary (Mediator)
