Aqueous Ionic Throat Solution for Sore Throat Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for sore throats, particularly those of infectious origin, are inadequate as they lack immediate and long-term effectiveness, often disrupt the oral-pharyngeal flora, and can be unsafe for repeated use, especially in children and the elderly, with existing products also prone to microbial contamination and adverse reactions.
Innovation Solution
An aqueous ionic solution comprising a hypertonic mineral salt solution, polyols of plant origin, sucrose esters, propolis, and essential oils, which provides antiseptic, anti-inflammatory, and osmotic actions, is stable, non-irritating, and suitable for frequent use without adverse effects, effectively addressing pain, inflammation, and microbial presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If topical antiseptics are used to treat sore throats, then microbial infection is addressed, but the oral-pharyngeal flora is disrupted and pain relief is insufficient
Solution Approach 1:
The patent combines multiple active ingredients (hexetidine antiseptic, lidocaine anesthetic, and anti-inflammatory compounds) into a single throat spray formulation. This merging allows the product to simultaneously provide antiseptic action against pathogens, pain relief through local anesthesia, and anti-inflammatory effects, thereby addressing the limitation of single-function antiseptics that disrupt flora without providing pain relief.
Solution Approach 2:
The invention uses a composite formulation containing multiple chemically distinct components working together: hexetidine (antiseptic), lidocaine (anesthetic), and anti-inflammatory agents. This composite approach enables multifunctional action (antiseptic + analgesic + anti-inflammatory) in one product, resolving the contradiction between effective pathogen targeting and harmful side effects on oral flora and symptom management.
2Object-generated harmful factors
If local anesthetics are combined with antiseptics for pain relief, then sore throat pain is reduced, but aspiration risk increases and mucociliary function is impaired
Solution Approach 1:
The patent applies local anesthetic (lidocaine) at controlled concentrations that provide sufficient pain relief for sore throat symptoms without reaching levels that would cause complete loss of protective reflexes. This partial action approach balances effective analgesia with safety, reducing aspiration risk while maintaining adequate pain management.
Solution Approach 2:
The formulation includes compounds that support mucociliary function and prevent stagnation of infected mucus, ensuring continuous clearance action. The spray delivers sustained relief while maintaining the natural protective mechanisms of the respiratory tract, counteracting the potential impairment from anesthetic use.
3Reliability
If repeated use of antiseptics is performed to maintain infection control, then pathogen coverage is comprehensive, but the resident flora is weakened and recurrence risk increases
Solution Approach 1:
The patent extracts and targets only the pathogenic components while preserving beneficial flora through selective action. The hexetidine antiseptic component provides targeted pathogen elimination without the broad-spectrum destruction of resident flora, allowing faster recovery of protective microbial communities and reduced recurrence risk with repeated use.
Solution Approach 2:
The formulation uses specific concentrations and combinations of active ingredients that modify the therapeutic parameter profile to favor pathogen elimination while sparing beneficial flora. This parameter optimization enables repeated administration without cumulative damage to the oral-pharyngeal ecosystem, maintaining infection control while supporting flora recovery.
4Reliability
If hypertonic mineral salt solution is used for osmotic action, then decongestant effect is achieved, but immediate pain relief is insufficient
Solution Approach 1:
The patent merges the hypertonic mineral salt solution (providing osmotic decongestant action) with local anesthetic compounds (providing immediate pain relief). This combination allows the single formulation to deliver both the gradual decongestant effect of salt osmosis and the immediate analgesic effect of lidocaine, resolving the insufficiency of pain relief from salt solutions alone.
